CHAPTER 2: Introduction 2. Introduction 2.1 Overview The 5250 Adapter Cards allow emulation of IBM 5250 terminals and printers on your PC equipment. By installing these Cards, you can access the full resources of an IBM midrange computer (such as S/36, S/38, or AS/400) by simply connecting your PC over twinaxial cable. The Adapter Card is connected to the IBM host through a twinaxial cable. The Adapter Card’s cable-through feature allows multiple PCs to be connected to one port of the IBM® host system.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL 2.3 What’s Included • 5250 Adapter Card. • Auto-terminating twinaxial cable assembly (this connects the twinax cables to the Adapter Card). • Windows® Utility diskette. • This user’s manual. NOTE The external connector on the Adapter Card provides a connection to the autoterminating twinax cable assembly. Make sure you use only the cable assembly provided with the Adapter Card.
CHAPTER 2: Introduction If you’re using Windows 95 or 98, which supports PnP devices, no external Configuration Utility is needed. If you’re using MS-DOS or Windows 3.1, then a Configuration Utility can be implemented as an application program. The Configuration Utility of a PnP system is usually supplied by the computer manufacturer. One example of this type of program is the ISA Configuration Utility, or ICU.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL 3. Software Installation Before installing the Adapter, please install the included Windows Utility diskette. This diskette contains the 5250 Windows Configuration Utility, Enabler, Diagnostics, and Adapter Handler in a compressed format. Also included on this diskette are the CEM5250.386, CEM5250.VXD, and TwinaxOEM.sys device drivers, an installation utility, and a readme.txt file.
CHAPTER 4: Hardware Installation 4. Hardware Installation 4.1 Installation Procedures 4.1.1 INSTALLING THE ADAPTER CARD Your PC manual contains instructions for installing options such as this Adapter Card. Follow the instructions in that manual to do the following: • Power off and unplug the system unit. • Remove the system unit’s cover. (Not applicable for the PC472C.) • Install the Adapter Card. • Replace the system unit’s cover. (Not applicable for the PC472C.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL NOTE The PC should be turned off and unplugged from the wall outlet before twinax cables are connected or disconnected. 4.2 Configuring the Adapter 4.2.1 5250 ISA ADAPTER CARD (PC473C) If you are installing this adapter in a Plug-and-Play computer, please read Section 4.2.1.2 prior to installing the adapter. 4.2.1.
CHAPTER 4: Hardware Installation 4.2.1.2 Plug-and-Play Environments This section describes the installation and configuration requirements for using the Adapter Card in a Plug-and-Play (PnP) compatible system. In order to effectively use the Adapter Card in a PnP computer, the part of the computer that manages system resources must be made aware of the Adapter Card and the resources that it requires.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL Windows 95/98 will then configure the hardware, and display the hardware settings. Make a note of the hardware settings if you plan on using any third-party software. You will have to reboot Windows 95/98 in order for the new configuration to work. If Windows 95/98 cannot configure the Adapter Card because of configuration conflicts, it will inform you of the possible corrective actions to try. 4.2.1.4 MS-DOS and Windows 3.
CHAPTER 4: Hardware Installation 4.2.2.3 Non-Plug-and-Play Systems (Legacy PCs) The 5250 Plug n Play Adapter Card can be configured in older PCs without Plug-and-Play capability. The Adapter has been shipped with a Configuration Utility, which will allow you to select the system resources in these systems. In older systems, all resources for this adapter are set by the DOS 5250 configuration program (DCFG5250) program. The adapter is not enabled until the Enabler (ENB5250) program is executed.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL When starting Windows 95/98, the operating system checks for any new hardware devices. The first time Windows 95/98 is started after the 5250 Plug n Play Adapter Card has been installed, the message New Hardware Found will appear in a dialog box. Under the New Hardware Found message, the new hardware will be identified; in this case it will have found the 5250 Plug n Play Adapter Card.
CHAPTER 4: Hardware Installation The 5250 PCMCIA Adapter Card is supplied with a self-terminating twinax cable assembly. There is a small 15-pin connector which is plugged into the 5250 PCMCIA Adapter Card. This connector is keyed and can only be plugged in one way. Please observe the keying and do not force the cable into the connector. It is recommended that the twinax cable assembly be attached to the 5250 PCMCIA Adapter Card prior to applying power to the computer.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL The resources can also be observed by executing the GETW95C.EXE program in the 5250CARD directory. The resource information passed from Windows 95/98 to the CEM5250.VXD device driver will be displayed. Since Windows 95/98 handles assigning all the resources, no memory exclusion statements will be required as with Windows 3.1. 4.2.4 5250 PCI ADAPTER CARD (PC470C) AND PCI EXPRESS CARD(PC478C) The 5250 PCI Adapter Card is fully compatible with the PCI Rev. 2.
CHAPTER 4: Hardware Installation To observe the resources assigned by Windows 95/98 for the adapter, click on Start, then Settings, then Control Panel, and then double-click on System. Click on the Device Manager Tab, then double-click on 5250 Emulation Adapters. There will be an entry for the 5250 PCI Adapter. Double-click on this entry and then select the Resources tab. The display will now show the 5250 PCI Adapter Card resources. The resources can also be observed by executing the GETW95C.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL Figure 4-2. Memory jumper on the PCI Express Card. You can place the jumper either on the upper two pins or the lower two pins (see Figure 4-3). When you place the jumper in the high memory position, the card will function anywhere in memory (high or low). When the jumper is in the low memory position, it will only function in low memory. Jumper setting for low memory Jumper setting for high memory Figure 4-3. Jumper settings for high and low memory.
CHAPTER 4: Hardware Installation Table 4-1 describes the advantages and disadvantages of using the high and low memory configuration on your PCI or PCI Express adapter. Table 4-1. Advantages and disadvantages of using the high and low memory configuration Memory Advantages Disadvantages High Memory Compatible with all PCI v2.1 compliant PCs. Old legacy applications may not work. Low Memory All legacy applications will still work. May fail in some PCs that reserve low memory.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL Seven Sessions The PCI Express card allows up to seven simultaneous emulation sessions to be active (6 display sessions and 1 printer or 7 display sessions) using the Vislink v5.10 software. Each session must have its own unique station address. SNA or APPC emulation programs such as Client Access for Windows or Rumba still only use one physical station address.
CHAPTER 4: Hardware Installation 2 MHz Mode 2 MHz mode increases the rate at which data is transferred on the twinax line. Normally, data is transferred at 1 Mbps, but the 2 MHz mode doubles the line speed, allowing transfers to occur at 2 Mbps. NOTE All stations on the line must be 2 MHz capable in order for this function to work. If there is even one station at the lower speed, all stations will drop down to the lower speed.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL 5. Utility Software 5.1 Enabler Program This program is primarily used for Windows 3.x applications. It will not work on PCI cards that are using memory above 1 MB. See the PCI card memory resources information found in Section 4.2.4. The Enabler program is used to enable the Adapter. This program is run automatically by the Diagnostic and Adapter Handler software. It may also be called from the DOS command line in order to test your configuration.
CHAPTER 5: Utility Software 5.2 GETW95C Program The GETW95C.EXE program is provided on the Utility diskette to allow the operator to get configuration information and will display the resources assigned to the Adapter by Windows 95/98. The CEM5250.VXD driver must have been installed prior to executing this program. The CEM5250.VXD driver is normally installed automatically by Windows 95/98 when the Adapter Card is first installed in the system.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL 5.3 SETPCI Program The SETPCI.EXE program is used to configure the PCI Card to function below and above one megabyte. This utility cannot be run under Windows 95/98/NT. It must be run from a DOS or Windows 95/98 boot disk. After booting from a DOS or Windows boot disk, the program can be run by the following command line: pciset.exe The program will try to detect the presence of a PCI bios and the PCI Card. If found, the following menu will be displayed.
CHAPTER 5: Utility Software Option 3: Irq Mode (High Memory) This mode sets the PCI card to run with an interrupt, and to run anywhere in memory (the BIOS will usually assign this to above one megabyte). Option 4: No Irq Mode (High Memory) This mode sets the PCI card to run without holding an interrupt, and to run anywhere in memory (the BIOS will usually assign this to above one megabyte). See Appendix B for more information on non-interrupt mode.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL SYSTEM.INI file. The entry can also be added by using any text editor and adding the following line to the [386Enh] section: Device=CEM5250.386 Once installed, the CEM5250.386 VxD will be loaded from the Windows startup files. The system must be rebooted in order for this change to take effect. Do not use this file on Windows 95/98 systems. 5.5.3 TWINAXOEM.SYS There is a Windows NT® device driver called TwinaxOEM.
CHAPTER 5: Utility Software 5250 Diagnostics File View Help Test Status: Ready Run Online Tests Loop Continuously Loop Count: Press Start to begin diagnostic tests... Start Close Help Figure 5-1. 5250 diagnostics (16 bit). This diagnostics utility uses the 5250 Enabler program to gain access to the 5250 emulation card. The enabler program will not work on a PCI card using memory above one megabyte, so the 16-bit diagnostics will fail, however the 32-bit diagnostics program will run properly. 5.6.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL NOTE The MicroPlus, PnP, and PC Card adapter types are not capable of using memory above one megabyte, so the 16- or 32-bit diagnostics can not be used. The 5250 Windows Diagnostics can be used in both Windows 3.x and Windows 95/98 systems (not NT). It will aid in determining if your Adapter is functioning properly. Extensive help information can be viewed online by clicking on the Help button followed by the Search option.
CHAPTER 5: Utility Software DCFG5250 The configuration program displays the main menu at the top of the screen, and the current configuration in a window at the bottom. Context-sensitive help is available by pressing . If the message: Cannot open cfg5250.dat Press any key to continue appears, exit the configuration program and check to see that the CFG5250.DAT file exists, and that it is in the directory indicated by the enabler environment string (see Section 5.1).
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL values selected to be programmed into the PC471C’s non-volatile memory. In the Fixed Resource Mode, a PnP system will not be able to move the board’s resources and will assign the fixed values programmed in the adapter’s non-volatile memory. This should only be used when running an emulation program that does not support the flexible resource assignment of a PnP system. When using the 5250 Enabler and VxD, you should stay with the Normal PnP mode.
CHAPTER 5: Utility Software When Card Services is selected, the PCDD5250.SYS device driver must be loaded via your CONFIG.SYS file, as instructed by the installation program. Note that using Card Services with any of the “Values Assigned by” selections is preferable to using any of the hardware-specific selections, as the use of Card Services is more likely to avoid configuration conflicts. If your system does not have Card Services, then one of the hardware controllers should be selected.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL Interrupt Level The IRQ item on the Hardware menu allows the selection of an interrupt request line that will be used by the Adapter. The default value is 5. In most systems, interrupt request levels cannot be shared. 5.9 DOS Diagnostics The 5250 DOS diagnostics can be used in a DOS environment only. To run the Diagnostics, make sure that the diagnostic program (DIA-EA.EXE, DIAPNP.EXE, DIA-PCC.EXE or DIA-PCI.
CHAPTER 5: Utility Software “1” will result in the diagnostics being run once. “2” will result in the tests being run a user-specified number of times. (This mode is useful when searching for an intermittent problem.) “3” exits the diagnostic program and returns control to MS-DOS®. If option “1” on the main menu is selected, the diagnostic tests are run once. If any test fails, an error code and error message are displayed.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL NOTE The tests may also be canceled when an error is detected by entering a “C.” The test will then ask you whether to run the online tests, as in option “1” above; however, it asks before the tests start, and only once, not on each pass of the tests. NOTE A problem with the Adapter could result in an incorrect list of active station addresses in this situation. See Appendix A for suggestions for solving problems with the Adapter. 5.
CHAPTER 5: Utility Software To invoke D5250AH, enter the following at the DOS command prompt: D5250AH [/U] [/?] The items in the brackets are optional parameters. The brackets themselves are not entered. The parameter U may be entered in upper or lower-case letters; parameter values are entered in hexadecimal notation. The /U parameter specifies that the adapter handler is to be removed from memory (unloaded). For example: D5250AH /U The /? parameter displays summary help.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL Appendix A. Error Codes and Conflict Resolution The following list describes the most common error codes and possible corrective actions that can be taken. The corrective action is intended to help you resolve the problem without having to make a service call. A Windows help file, included on the Windows Utility diskette, describes in detail how to configure your Adapter with various third-party applications. A.
APPENDIX A: Error Codes and Conflict Resolution For Windows 3.1 systems, use the configuration program (DCFG5250) to change the adapter’s IRQ setting. For most DOS 5250 emulators and the IBM adapter handler (E5250AH), you must use their configuration software or command line parameters (for example, E5250AH /L7). A.1.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL reserve this address space, add the following to your CONFIG.SYS files for the respective memory manager. If a different memory manager is used, find the proper syntax for excluding the space required for the Adapter Card. EMM386 (Microsoft) device=C:\DOS\EMM386.EXE X=DC00-DDFF QEMM386 (Quarterdeck Office Systems) device=C:\QEMM\QEMM386.SYS ARAM=DC00-DDFF 386MAX or BLUEMAX (Qualitas) device=C:\386MAX\386MAX.SYS RAM=DC00-DE00 (RAM parameter may be in 386MAX.
APPENDIX A: Error Codes and Conflict Resolution A.1.3 I/O CONFLICTS Many older PC adapters only use 10 address bits for decoding I/O space. The Adapter Card uses all 16 bits of the I/O address space for decoding its location. Since the Adapter Card uses all 16 bits, it’s possible for another adapter using only 10 bits for decode to be mapped in the same space even though the actual I/O port addresses are different.
5250 ADAPTER CARDS: HARDWARE INSTALLATION MANUAL A.2 Miscellaneous Problems A.2.1 TWISTED PAIR OR FAULTY CABLE PROBLEMS Error 5141 Link Connection Lost; -PC Support & CA/400 Error 0042 | 0043 - Online queue data incorrect; -Diagnostics You may encounter Diagnostic error 42 or 43 above or intermittent “line drops” if you are using twisted-pair wire or incorrect cable termination.
APPENDIX B: Non-Interrupt Mode Appendix B. Non-Interrupt Mode The Adapter normally uses one of the PC’s Interrupt Request Lines (IRQ) for optimum performance. However, the Adapter may be configured to operate without using an IRQ. This non-interrupt mode is valuable for PCs that have no free IRQs. Depending on your Adapter Card and PC operating system, you will have different options for configuring the interrupt mode. For more detailed information, see the online help.
