Chapter 1: Overview
Guide Organization This guide provides directions on how to install and set up the AT&T Intelligent Ports Card, Model 1600 (IPC-1600). It also explains how the product interacts with other components of your computer system and advises you on troubleshooting. The remainder of this guide is divided into the following: * ■ Chapter 2, “MS-DOS* Device Driver Installation,” describes how to install the MS-DOS device driver software.
Guide Organization 1-2 ■ Appendix A, “Hardware Parameter Settings,” provides information about setting the Input/Output (I/O) port address, controller memory starting address, and the Interrupt ReQuest (IRQ) level for the IPC-1600. A sample configuration record is provided for keeping track of installed card parameters and characteristics. ■ Appendix B, “Serial Input/Output Device Interface,” provides information about port electrical and physical characteristics.
What Is an IPC-1600? The AT&T Intelligent Ports Card, Model 1600 (IPC-1600) is a sixteen port, intelligent, serial Input/Output (I/O) controller with an 80C186 16-bit microprocessor running at 12.5 MHz. The sixteen RS-232, asynchronous ports are wired to RJ-45 (10-pin) fanout modules via two 80-conductor ribbon cables. The IPC-1600 operates with the AT&T UNIX System V/386 Release 3.
What Is an IPC-1600? ■ Two diskettes [one 3.5-inch, 720-KB diskette (COMCODE 405977737) and one 5.25-inch, 360-KB diskette (COMCODE 405977752)] each labeled “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0.” ■ Two diskettes [one 3.5-inch, 1.44-MB diskette (COMCODE 405977786) and one 5.25-inch, 1.2-MB diskette (COMCODE 405977802)] each labeled “Intelligent Ports Card (IPC-1600) UNIX System V/386 Device Drivers, Version 1.0.
IPC-1600 Architecture The architecture of the IPC-1600 provides many useful and powerful multiuser capabilities under the UNIX system. Furthermore, single-user applications using the IPC-1600 for general-purpose I/O, as well as for industrial control, can be done under MS-DOS. IPC-1600 features include the following: ■ One 80C186 16-bit microprocessor (12.5 MHz). ■ Industry Standard Architecture (ISA) bus connectors (any 16- or 32-bit slot can be used).
Ports and Drivers The software that takes care of the I/O tasks between the user terminals/MODEMs/printers and the UNIX system is built into the IPC-1600 firmware to increase the UNIX system performance. End users get the benefit of immediate keyboard/screen response and the enhancement of the overall performance of the UNIX system. The UNIX system driver supports the 8-bit character set. The MS-DOS device driver supports an 8-bit character set and the MS-DOS level interface.
Information in the Examples The contents of most of the displays presented in this guide depend on the particular machine configuration. Therefore, the information displayed on your terminal will vary from the information presented in the examples. In particular, the installation software displays and display options are dynamic with respect to available system configuration resources. All displays in this guide were taken from an AT&T 6386E Work Group System (WGS).
Hexadecimal Notation Throughout this guide, base 16 numbers (hexadecimal) are denoted by a lowercase letter “h” suffix. For example, 100h.
MS-DOS and UNIX System IPC-1600 Use Strategy Native MS-DOS and UNIX System Operation Requirement: The host computer must be set up to have base memory above 512KB (512KB to 640KB) disabled for the IPC-1600 to use controller memory starting addresses 080000h or 090000h. Refer to the customer documentation that came with your AT&T Work Group System (WGS) for information on how to disable base memory.
MS-DOS and UNIX System IPC-1600 Use Strategy MS-DOS Under Simul-Task and UNIX System Operation If you plan to use MS-DOS under Simul-Task 386 or to use only the UNIX system for the operation of the IPC-1600, skip Chapter 2. Start with Chapter 3, “UNIX System Device Driver Installation,” and follow the instructions for the installation of the software. Then install the IPC-1600 board per Chapter 4, “Hardware Installation.
Chapter 2: MS-DOS Device Driver Installation
Introduction Comment: If you are using only the UNIX system for Intelligent Ports Card operation, you can skip this chapter and go to Chapter 3, “UNIX System Device Driver Installation.” If you plan to use MS-DOS under Simul-Task 386, follow the procedures in Chapter 3. The instructions in this chapter apply only to native MS-DOS. See the section, “IPC-1600 Diagnostics,” in Chapter 7 for diagnostics information.
Installation Procedure The following steps define the sequence of events for installing the IPC-1600 for use in the native MS-DOS environment. Read the entire procedure and supporting paragraphs before doing the installation. Write down the hardware parameter settings for each board to be installed as you read through the procedure the first time. Then refer to these notes when you do the procedure.
Installation Procedure Preconfigure the IPC-1600 Boards Set the starting controller memory address (DS1, SW8—1), the I/O address (DS1, SW11—9), and the IRQ level (DS2, SW8—1) for each IPC-1600 to be installed. Note that IRQ levels are not used by the MS-DOS driver. Therefore all DS2 switches should be set to the OFF position (Note 2). Refer to Appendix A, “Hardware Parameter Settings,” for switch location and decode information. The following table identifies the initial options.
Installation Procedure Install the Hardware Refer to Chapter 4, “Hardware Installation,” and follow the instructions for the installation of the board. Ignore any instructions in Chapter 4 involving the DS1 and DS2 DIP switches, since they have already been done in this procedure. Load the Software Power up the system [AT&T Work Group System (WGC) computer] to boot native MS-DOS (Version 3.0 or later) from either the floppy diskette or the system disk drive.
Installation Procedure Now, change directory (cd) to IPC and copy the files on the diskette in the “A” drive or in the “B” drive to the system disk drive as follows. The example uses the “A” diskette drive; the system disk is the “C” drive. Change directory to an optional separate directory to contain the IPC-1600 software. C: $ cd ipc Copy the files from the “A” drive to the “C” drive C:\IPC $ copy a:*.* /v A:IPC16CNF.EXE A:IPC16DOS.SYS A:IPC16DIA.
Installation Procedure Create or Modify the CONFIG.SYS File Use an editor, such as EDLIN, to change (or create) the CONFIG.SYS file in the root directory of the drive from which you boot MS-DOS. Add the following line to the CONFIG.SYS file if the IPC16DOS.SYS file is in a separate directory. The complete path name must be specified for the DEVICE entry. For example, if the driver is in the a directory path \IPC, the CONFIG.SYS file entry is as follows. DEVICE=\IPC\IPC16DOS.
Installation Procedure Execute IPC16CNF to Configure the Driver The IPC16CNF.EXE program is used to configure or reconfigured the IPC-1600 MS-DOS driver and to specify individual channel (port) parameters. The following screen shows the initial IPC16CNF program display.
Installation Procedure Number of Boards Option The N)umber of Brds option is used to specify the number of installed IPC-1600 boards. The default is seven boards. Once specified, the initial table is redrawn to show the number selected. Memory Segment Option The M)emory Segment option is used to specify the controller memory starting address for all IPC-1600 boards. When selected, the table is redrawn to show the new data.
Installation Procedure Start Channel Number Option The S)tart Channel # option is used to specify the beginning channel number for all IPC-1600 provided ports. Each IPC-1600 port in the system is assigned a number that distinguishes it from the other ports in the system. These channel numbers are used by the driver and INT 14h calls. Selecting the starting channel number specifies the range of numbers the communications ports will use. The standard MS-DOS COM1 and COM2 ports use channel numbers 0 and 1.
Installation Procedure Channel Parameters Option The following screen shows the initial display for changing parameters for a given IPC-1600 board. The display shows the default parameters. After selecting a channel, options are presented for changing the ENABLE, BAUD, MODE, HANDSHAKE, and NAME parameters. The display is automatically updated to show what channel has been selected and to show the parameter data.
Installation Procedure After selecting a channel, the following options are available. Q)uit E)nable B)aud Select Parameter: M)ode H)andshake N)ame C)hange Chanl # The E)nable option is used to enable (ENBL) or disable (DSBL) the selected channel (port) as shown in the following screen display. B) ENBL A) DSBL Select Settings: The B)aud option is used to set the BAUD rate for the selected channel (port) as shown in the following screen display.
Installation Procedure The H)andshake option is used to select the flow control for the selected channel (port). The following screen display shows how to select the flow control options. A) NONE Select Handshake B) XON/XOFF C) RTS/CTS D) BOTH Protocol: The N)ame option is used to change the MS-DOS name assigned to the channel. No name is used if INT 14 support has been selected. The following screen display shows how to specify a new channel name. Old Name : COM5 New Name (8 characters max.
Installation Procedure Finishing Up Quitting the IPC16CNF program using the Q)uit option produces various messages depending on what has been done before the exit request. During the exit process, a combination of the following prompts can be displayed. Re-Configure the IPC1600(s) (Y/*) : Responding “Y” to this prompt causes the IPC-1600 to be reprogrammed. The system can then be used without a reboot.
Installation Procedure Reconfigure the Boards If Necessary Requirement: Be sure to take notes throughout this phase of installation. Write down I/O addresses and the memory addresses so that once the device drivers have been installed you will have a permanent record to which you may later refer. Likewise, if you are going to remove or add a board, write down any changes that you make in the process. A sample configuration record is shown in Appendix A.
Accessing Serial Ports After you have completed the hardware phase of the installation and the configured driver is loaded, use the serial I/O ports on the IPC-1600 as if they were files with file names COM5 through COM20 ..., as applicable.
Removing the MS-DOS Device Driver To remove the Intelligent Ports Card MS-DOS device driver from the system, use an editor, such as EDLIN, to delete the entry in the CONFIG.SYS file which corresponds to DEVICE=\IPC\IPC16DOC.SYS. Then reboot the system. If you want to free the system disk space occupied by the IPC-1600 software, delete (DEL) the IPC16DOS.SYS, IPC16CNF.EXE, and IPC16DIA.COM files along with the IPC directory (RMDIR).
Removing the MS-DOS Device Driver The following screen display shows how to remove only IPC-1600 driver and configuration software files from the system disk. The IPC16DIA diagnostic program remains on the system disk. C:\ $ d e l ipc\ipc16dos.sys C:\ $ d e l ipc\ipc16conf.exe C:\ $ After editing the CONFIG.SYS file, reboot the system to reconfigure the system.
Limitations of the IPC-1600 MS-DOS Device Driver All IPC-1600 boards in the system must be assigned the same starting controller memory address; otherwise, only one board can be accessed under native MS-DOS. All IPC-1600s can be diagnosed regardless of controller memory address assignments; however, the controller memory address switch settings must be below 1MB. This MS-DOS device driver will NOT drive the following: ■ Any indigenous serial I/O ports such as COM1: and COM2:.
Chapter 3: UNIX System Device Driver Installation
Introduction Comment: If you are using only native MS-DOS for IPC-1600 operation, you can skip this chapter. Chapter 2, “MS-DOS Device Driver Installation,” provides MS-DOS driver installation and setup instructions. If you intend to run MS-DOS under Simul-Task 386, use the installation instruction in this chapter.
Tunable Parameters and Memory Guidelines The following table shows the tunable parameter guidelines for IPC-1600. IPC-1600 TUNABLE PARAMETERS SYSTEM MEMORY PARAMETER NCLIST NPROC NREGION 2MB 4MB 8MB 16 MB+ 120 100 210 170 150 300 560 200 600 1180 400 1200 The installation of the IPC-1600 UNIX system driver and related software is independent of these requirements. However, to obtain proper system performance, these parameters should be adjusted before the installation of the IPC-1600.
Tunable Parameters and Memory Guidelines Sufficient system memory must be available to support the number of IPC-1600 boards being installed. The following system memory guidelines should be followed.
General Installation Procedures Power up the AT&T WGS computer, making sure that no diskette is in the diskette drive(s) during the boot phase. Wait until the UNIX system is ready, and then log in using either “root” or the privileged access user administration login you have been assigned. Insert the “Intelligent Ports Card (IPC-1600) UNIX System V/386 Device Drivers, Version 1.0” diskette into the appropriate diskette drive (5.25-inch or 3.5-inch drive) and close the diskette drive door.
Installation Procedures Comment 1: The installation software displays are dynamic and depend on the type and configuration of the machine. All possibilities are not presented in the examples. Comment 2: AT&T Framed Access Command Environment (FACE) subsystem is an optionally orderable product. If available, the AT&T FACE software should be installed before installing the IPC-1600 software.
Installation Procedures Enter the number corresponding to the action you want to specify. After you specify either item 1 or 2, you will be asked to confirm your choice. Specifying item 3 terminates the installation process with nothing being installed. Select option 2 to install the device driver and the AT&T FACE menus for the IPC-1600.
Installation Procedures Specify Shared or Board-Unique Hardware Interrupt Assignment The installation process then asks you to specify how hardware interrupts are to be assigned. The IPC-1600, Intelligent Ports Card - Version 1.0 package allows the ports boards to be configured to all use the same interrupt (shared) or for each board to be configured to a different interrupt. If interrupts are shared, a maximum of 7 ports boards may be installed.
Installation Procedures Specify Shared or Board-Unique Controller Memory Assignment The installation process then asks you to specify how controller memory is to be assigned. The IPC-1600, Intelligent Ports Card - Version 1.0 package allows the ports boards to be configured to all use the same controller memory (shared) or for each board to be configured to a different controller memory starting address.
Installation Procedures If you specify to share controller memory among all boards, you are then asked to select the controller memory starting address to be used by all IPC-1600 boards as follows. The IPC-1600 comes from the factory with the controller memory address range set to 080000h-08FFFFh. Remember to select a controller memory address range which does not conflict with other board types in the system. The device driver used for IPC-1600, Intelligent Ports Card - Version 1.
Installation Procedures Specify the Number of Boards You are then asked to specify the number of boards to be installed as follows. Remember that the number of boards indicated in the example is dynamic with respect to the system type and available system configuration resources. The current system configuration will allow for up to 7 IPC-1600 controller boards to be installed.
Installation Procedures Assigning Board-Unique Hardware Interrupt Request Level If you specified board-unique hardware interrupt assignments, the system now displays a list of available hardware interrupts and prompts you to enter the interrupt number to be assigned to the first board that you wish to install. At the factory the hardware is set to IRQ10; if IRQ10 is already assigned, the first available interrupt in the displayed list appears as the default.
Installation Procedures Assigning an I/O Address The system now displays a list of available I/O addresses and prompts you to enter the I/O address to be assigned to the board. The IPC-1600 comes from the factory with the I/O address set to 100h; if I/O address 100h is already assigned, the first available I/O address in the displayed list appears as the default. The hardware I/O address will be set to match the software assignment(s) later in Chapter 4.
Installation Procedures Assigning Board-Unique Starting Controller Memory Address If you specified board-unique controller memory assignment, the system now displays a list of available starting controller memory addresses and prompts you to enter the address to be assigned to the board.
Installation Procedures Remember that if you are adding more than one board, the controller memory addresses should not conflict. The IPC-1600 is 16-bit transfer board requiring 64KB of host memory. Also, 8-bit and 16-bit transfer boards cannot share a 128KB memory window. Controller memory address space cannot conflict with Basic Input/Output System (BIOS) shared memory. Be sure to write down the address(es) that you specify.
Installation Procedures Confirming the Data After you enter the three items of data, a confirmation screen displays your choices and prompts you either to verify what you have selected or to indicate that it is unacceptable.
Installation Procedures Following the acceptance of the last board, an overall IPC-1600 configuration summary is displayed. The following is an example of how the display and prompt may appear on your screen: Board # ------- Is TYPE ---- IRQ --- I/O Addr. --------- Mem. Addr --------- 1. IPC-1600 10 100 080000 2. IPC-1600 10 110 080000 this configuration acceptable? (y or n) To accept the data, press the Y key and then press the ENTER key.
Installation Procedures Completing Driver Installation After you enter Y in response to the last prompt, the system completes the driver installation by rebuilding the UNIX system kernel. This process takes several minutes. The following message appears: The UNIX Operating System will now be rebuilt. This will take approximately 2 minutes. Please wait. The UNIX Kernel has been rebuilt.
Installation Procedures Once the kernel has been rebuilt, another message displays: Confirm To complete the install/remove process a shutdown is now being initiated automatically. Make sure your floppy drive is empty. If you are installing or removing controller boards, you may power down the system after the shutdown has completed. Strike ENTER when ready or ESC to stop. Remove the “Intelligent Ports Card (IPC-1600) UNIX System V/386 Device Drivers, Version 1.0.
Modifying Kernel Configuration Removing All IPC-1600 Boards To remove all IPC-1600 board information from the kernel, log in as “root” and execute removepkg. When prompted, select the “IPC-1600, Intelligent Ports Card — Version 1.0” item. Changing IPC-1600 Configuration You can reinstall the driver on top of the current driver when you need to add or change the IPC-1600 configuration information.
Chapter 4: Hardware Installation
Introduction The IPC-1600 board can be installed in any 16-bit or 32-bit bus expansion slot in following machines: ■ AT&T 6386E Work Group System ■ AT&T 6386/25 Work Group System ■ AT&T 6386E/33 Work Group System ■ AT&T 6386E/33 Work Group System Model S. Refer to the appropriate “User's Guide” supplied with your machine for board installation instructions. This chapter guides you through the process of installing the appropriate hardware.
Preparation Prepare Machine for Installation If the machine is powered-up and is running the UNIX operating system, use the shutdown command to bring down the operating system as shown in the following screen display. # cd / # shutdown Set the power switch of the system and of all external devices to “OFF.” Unplug the system module power cord. Using the documentation that came with your machine, prepare an expansion bus slot for the installation of a board.
Preparation Prepare the IPC-1600 for Installation Set the Controller Memory Starting Address Locate the DS1 Dual In-line Package (DIP) switch (a group of eleven switches) on the IPC-1600. Refer to Appendix A, “Hardware Parameter Settings,“ for switch location information and instructions on how to set the controller memory starting address (DS1, SW8 through SW1) to correspond to the values established when installing the software (Chapters 2 and 3).
Connect the 16-Ports Fanout Module Cables After setting the I/O port address, the controller memory starting address, and the hardware interrupt request level for the board, you are ready to connect the ribbon cables and port modular cables to the 16-Ports Fanout module as follows. If you have the optional AT&T IPC-1600 Ports Cabinet, locate and install the cabinet now. Refer to Appendix C, “AT&T IPC-1600 Ports Cabinet,” and the documentation that came with the cabinet for installation information.
Connect the Ribbon Cables to the IPC-1600 Route the ribbon cables from the 16-Ports Fanout module to the host computer. Thread the ends of the ribbon cables through the board slot opening in the host computer and connect them to the IPC-1600 board. The connectors are keyed for proper alignment with the 80-pin headers on the board. Observe the port markings on the front of the 16-Ports Fanout module to insure correct port numbering on the fanout module.
Install the Board Follow the instructions in the documentation that came with your machine for installing a board. Carefully pass the excess ribbon cable through the board slot opening until the board can be plugged into the 16- or 32-bit Industry Standard Architecture (ISA) bus connector. Align the IPC-1600 board with the selected board slot and plug the board into the corresponding connector. Secure the IPC-1600 board with the mounting bracket using the 2.25-inch long-shank screws.
Chapter 5: Managing the Serial Ports
Introduction This chapter defines the IPC-1600 device node names used in the UNIX system. This chapter also describes how to manage the serial I/O ports using either the hipcutils(1) command or the AT&T Framed Access Command Environment (FACE), which is optionally available with the UNIX System V/386 Release 3.2 and later. (If you are using the UNIX System V/386 Release 3.2 or later but do not have FACE, refer to the UNIX System V/386 Operations/System Administration Guide.
Definition of IPC-1600 Device Node Names Node Names There are two classes of device node names: ■ ttyis xyy (for software) ■ ttyihxyy (for hardware). The x is the board occurrence number. Board numbers are 1 through 7. The yy is the port number on the IPC-1600 board. Port numbers are 01 through 16.
Definition of IPC-1600 Device Node Names The following table shows all available device names for the serial ports with multiple IPC-1600 installation.
Definition of IPC-1600 Device Node Names Software Device Class The /dev/ttyisxyy device type must be used for I/O devices (terminals, printers, MODEMs, etc.) when software flow control is desired. The ttyisxyy class of device node names does not support hardware flow control via the standard Electronic Industries Association (EIA) RS-232C hardware handshaking signals (CTS and RTS). Flow control is provided under software control.
Definition of IPC-1600 Device Node Names Hardware Device Class The ttyihxyy provides the standard EIA RS-232C hardware handshaking and monitors the following: ■ Data Carrier Detect (DCD) ■ Clear To Send (CTS) ■ Ring Indicator (RI). The detection of the DCD loss causes the port to log off if the Hang UP on final CLose (HUPCL) flag is set. In addition, the presence of the CTS signal enables the IPC-1600 transmitter and the presence of the DCD signal enables the IPC-1600 receiver.
IPC-1600 Administration Via hipcutils The hipcutils command is used to administer IPC-1600 ports. The command is used to reset ports that are hung or otherwise not operable and to configure the Data Carrier Detect (DCD) wink and break durations for a port. Refer to the hipcutils(1) manual page which is provided as part of this package for additional information.
UNIX System V Release 3.2 Administration Via FACE The AT&T Framed Access Command Environment (FACE) subsystem is an optionally orderable product which provides an enhanced UNIX system user interface. Contact your AT&T Service Representative or authorized dealer for more information. The serial I/O ports are all under the control of the FACE subsystem which is under the UNIX system. AT&T FACE is a character-based user interface which presents the user with a logical view of the UNIX System V environment.
UNIX System V Release 3.2 Administration Via FACE In order for the Flow Control selection to select the device properly, you must explicitly set the Flow Control field or, at the least, you must move the cursor through the field. For Serial Printer Setup using the IPC-1600, select the “Serial Printer Port Setup” and refer to the UNIX System V/386 Release 3.2 FACE User’s/Administrator’s Guide for additional information.
Chapter 6: System Features
Features The IPC-1600 works in either 16-bit or 32-bit expansion I/O slots. The IPC-1600 provides sixteen identically configured serial I/O ports with a full complement of Electronic Industries Association (EIA) RS-232C/Consultative Committee International Telegraph and Telephone (CCITT) V.
Features ■ Break sequence (transmit data line held “low” for two consecutive stop-bit sequences). In addition, modem-handshaking line discipline and receive-error detection (such as framing error, data overrun error, and parity error) are built in. Transmit and receive data are buffered through the on-board Static Random Access Memory (SRAM) and passed between the IPC-1600 and the host processor via the high-speed dual-ported SRAM to enhance system performance.
Performance Characteristics The IPC-1600 supports the following bit per second rates: 38400, 19200, 9600, 4800, 2400, 1800, 1200, 600, 300, 200, 150, 134.5, 110, 75, and 50. The performance of the IPC-1600 expressed in terms of line occupancy at a prescribed baud rate in the raw and cooked modes with no flow control is as follows. In the cooked mode, canonical processing is enabled. In the raw mode, canonical processing is disabled.
Performance Characteristics The output capacity of the IPC-1600 is determined by the number of lines (ports) simultaneously operating at 98% occupancy with no flow control as follows. Raw Mode: 16 16 14 7 ports at 4,800 ports at 9,600 ports at 19,200 ports at 38,400 bps bps bps bps Cooked Mode: 16 16 14 7 ports at 4,800 ports at 9,600 ports at 19,200 ports at 38,400 bps bps bps bps Operating beyond these input limits with no flow control will result in loss of characters.
Power Consumption The IPC-1600 is supplied with +5V, +12V, and –12V via the Industry Standard Architecture (ISA) adapter card. The total typical case power consumption is as follows: +5V @ 2.00 Amperes = +12V @ 0.07 Amperes = –12V @ 0.10 Amperes = Total Power = 10.0 Watts 0.8 Watts 1.2 Watts 12.
Chapter 7: Troubleshooting the Intelligent Ports Card
Introduction This chapter includes detailed information on troubleshooting the Intelligent Ports Card and the use of the diagnostic program supplied on the “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0” diskette. Information on how to use the IPC-1600 with other products and other “Helpful Hints” are also provided in this chapter.
MS-DOS Boot Error Message The following error messages may be displayed at system boot time and can be caused by an incorrect board configuration. SRAM MEMORY ERROR (Indicates faulty memory or memory not found.) BIOS RESET ERROR (Indicates BIOS failed to initialize correctly.) The following error messages may be displayed at system boot time and can be caused by a hardware problem. FEPOS CODE MOVE ERROR (Indicates error when loading the on-board operating system.
IPC-1600 Diagnostics Copy Diagnostics to the System Disk Comment: This procedure is only for systems running native MS-DOS from the system disk drive. Power up the system [AT&T Work Group System (WGS) computer] to boot native MS-DOS (Version 3.0 or later) from the system disk drive. Insert the “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0“ diskette into the appropriate diskette drive and close the diskette drive door.
IPC-1600 Diagnostics Now, change directory (cd) to IPC and copy the IPC16DIA.COM file on the diskette in the “A” drive or in the “B” drive to the system disk drive as follows. The example uses the “A” drive. Change directory to an optional separate directory to contain the IPC-1600 software. C: $ cd ipc Copy the file from the “A” drive to the “C” drive C:\IPC $ c o p y a : i p c 1 6 d i a . c o m / v A:IPC16DIA.
IPC-1600 Diagnostics How to Run Diagnostics IPC-1600 diagnostics are run by executing the IPC16DIA program under native MS-DOS. There are six diagnostics which can be selectively executed from the IPC16DIA program. The program is terminated by the ESC key. Note that it is necessary to change the controller memory address assignment IPC-1600 boards set above 1MB to an address supported by diagnostics. Remember to reset the controller memory address switches for UNIX system operation, as applicable.
IPC-1600 Diagnostics You are next asked to select the starting memory address for the board to be tested as follows. Select the appropriate number (1-7) for the IPC-1600 memory address: 1)80000H 2)90000H 3)A0000H 4)B0000H 5)C0000H 6)D0000H 7)E0000H You are then asked to specify the IRQ level for the board to be tested as follows.
IPC-1600 Diagnostics The IPC16DIA program is terminated by entering an escape (ESC). The following screen shows that all diagnostics were successfully executed once for the specified board and then an ESC entered to quit the program. ------------------------------------------------------------------------------******** ******** *********** IPC-1600 DIAGNOSTICS Version 1.5.
IPC-1600 Diagnostics IPC-1600 Test Descriptions Host 64KB Dual-Ported Memory Tests The host processor dual-ported memory test diagnostics execute in the host processor. These tests write to memory, read the memory, and compare what is read to what was written. The IPC-1600 is held reset and the dual-ported memory is enabled during test execution. Host/lPC-1600 Interface Tests The host processor/IPC-1600 interface tests execute in both the host processor and the IPC-1600.
IPC-1600 Diagnostics IPC-1600 Communication Ports Tests The communication ports tests execute in both the host processor and the IPC-1600. These tests use the IPC-1600 FEPOS to exercise each port on the IPC-1600. A combination of four baud rate (1200, 9600, 19200, and 38400 bps), four data word sizes (5, 6, 7, and 8 bits), two stop bits (1 and 2), and three parity selections (none, odd, and even) are used to test each port.
Helpful Hints Typically, the lower interrupts on the Industry Standard Architecture (ISA) bus are used by other circuit boards in the system. Therefore, to prevent configuration conflicts, try using some of the higher interrupts (IRQ 10, IRQ 11, and IRQ 15) for the Intelligent Ports Card. Make sure that the Intelligent Ports Card is installed in a 16-bit or a 32-bit ISA-compatible bus slot.
Helpful Hints When using a Hayes* compatible MODEM, dial out once to configure the MODEM before caIling into the MODEM. The AT&T 446 Laser Printer and the HP† LaserJet Series II printer must be installed on a serial port configured as a ttyihxyy device under the UNIX system. Use stty clocal to prevent loss of printer data for printers which raise Data Carrier Detect (DCD) to signal erroneous data. These printers include the AT&T 446 Laser Printer and the HP LaserJet Series II printer.

Appendix B: Serial Input/Output Device Interface
Serial Port Characteristics At the IPC-1600 RJ-45 type modular jack connectors, each serial port is configured as Data Terminal Equipment (DTE). To connect an I/O device (terminal or MODEM) to a serial port requires a 10-conductor or 8-conductor modular cable and the appropriate 10-pin or 8-pin modular to 25-pin connector adapter. Modular cables and adapters are ordered separately for the IPC-1600. Each of the sixteen serial ports have the following characteristics.
Voltage Envelope The region between +3V and –3V is defined as the transition region and is considered an invalid level. A voltage more negative than –12V or more positive than +12V is also considered an invalid level. During the transmission of data, the “marking” condition is used to denote the binary state “1” and the “spacing” condition is used to denote the binary state “0.” Figure B-1 shows the voltage envelope.
IPC-1600 80-Pin Headers P3 and P4 P3 and P4 are each eighty-pin, right-angle headers. The 16-Ports Fanout Module ribbon cables connect to these headers as shown in Figure B-2. Connector P4 is used for ports 1 through 8; connector P3 is used for ports 9 through 16. The 16-Ports Fanout Module cable assembly has two 80-conductor ribbon cables. Cable “P4” connects to header P4 (ports 1 through 8); cable “P3” connects to header P3 (ports 9 through 16).

Compatibility with Other I/O System Cabling Overview To protect the investment in existing systems and cabling, provisions have been made to use the existing system cables and connectors with the IPC-1600. The existing cabling is used along with the appropriate IPC-1600 modular cables and adapters (previously described) to connect an IPC-1600 to the existing cabling sytem.
Compatibility with Other I/O System Cabling Intelligent Ports Card Model 802 (IPC-802) Interface When an IPC-1600 replaces an IPC-802, the existing serial I/O cables are used along with 8-conductor or new 10-conductor modular cables and associated adapters to provide the serial I/O connections. Figure B-13 shows how to connect IPC-1600 serial ports to existing IPC-802 I/O system cabling.
Compatibility with Other I/O System Cabling 3B2 Computer PORTS/EPORTS Interface Caution: Do NOT plug a 3B2 computer cross-over modular RJ-45 cable directly into the IPC-1600 RJ-45 receptacle (jack) connector. Inserting a 3B2 computer modular cable directly into an IPC-1600 jack does not provide RS-232C communication. Appropriate RJ-45 to DB-25 adapters must be used to provide proper RS-232C communication. See Figure B-13.

Appendix C: AT&T IPC-1600 Ports Cabinet
General Description Purpose The AT&T IPC-1600 Ports Cabinet (Figure C-1) is a wire-frame assembly providing mounting space for two 16-Ports Fanout modules (COMCODE 405977869). The cabinet can be placed on a table or floor or can be mounted on a wall or other stable surface. The wire-frame assembly includes wiring guides to facilitate the organized routing of the cables and cable strain relief. The overall dimensions of the assembled cabinet are roughly 10 inches high by 9 inches wide by 3.5 inches deep.
Installation Information Comment: Before doing any installation activity, you should first read through all the information in this section to gain a complete understanding of what needs to be done. General Instructions The general sequence to install the IPC-1600 ports cabinet is as follows. Step 1: Decide where and how to mount the cabinet. Step 2: Secure the wire-frame assembly to a stable surface (optional).
Installation Information Choosing a Mounting Location The AT&T IPC-1600 Ports Cabinet must be located within about 7 cable feet (2 meters), the length of the fanout module cable assembly, of the host machine. The method of mounting (floor, table, or wall) is a matter of convenience for your particular installation. The most physically secure method of mounting the cabinet is to fasten it to a stable surface. Secure-type mounting is recommended to protect the connections and apparatus.
Installation Information Installing the 16-Ports Fanout Module It is recommended that the upper position of the two mounting positions be used first to facilitate easy addition of the second 16-Ports Fanout module. The 16-Ports Fanout module snaps into the wire-frame assembly from the front of the assembly (Figure C-2). First put the slot on the left side of the 16-Ports Fanout module over the wire tab on the left side of the wire-frame assembly.
