1 1 Introduction Overview The Standard Multiport Async Solutions The standard C168P multiport boards offer 8 serial ports for connecting terminals, modems, printers, data acquisition equipment and any other serial devices to the PC/AT and its compatible systems. The Smartio C168P is equipped with custom-designed ASIC chip which replaces lots of conventional ICs and reduces the board to half-size. The whole family supports 16 bit architecture. Full range of I/O addresses and IRQs are available.
Hardware Configuration Method JP1 Switch ON 1 2 3 4 Jumper ......... ......... Smartio Family New : set I/O address and IRQ via software Utility. Traditional Multipoort Board Traditional : set switch and and jumper manually for I/O address and IRQ. Instead of using traditional jumper or switch for IRQ and I/O address settings, hardware configuration of each port is easily set by DOS utility, Io-irq.
Introduction Operating System Support The family is operational under most popular operating systems such as Windows NT, Windows 95/98, SCO UNIX/XENIX/OpenServer, DOS, Linux, QNX, FreeBSD, etc. However, MOXA device drivers for Windows NT, Windows 95/98, Linux and DOS are provided for easier installation, configuration and better performance. In this manual, chapters for MOXA Windows NT, Windows 95/98 and DOS device drivers are included.

Introduction Opt8J v v v RS-422/485 connection box with 8 port female DB25 connectors. 1.5 meter DB62 to DB62 cable. 110V or 220V adapter. C168 P Rx Tx 1 2 3 4 5 6 7 8 Opt8J Opt8J is the RS-422/485 connection box with 8 port female DB25 connectors for MOXA 8 port boards, including the C168P. There are 8-DIP switches on the side of the Opt8J. Each switch controls the communication mode (RS-422 or RS-485) of each port, respectively.
RS-485 Mode The Opt8J supports only 2-wire RS-485 communication. Set the respective switch to ON position to use RS-485 interface. This means the port can transmit data only when RTS is asserted, and receive data only when RTS is not asserted (half-duplex). Refer to Chapter “Connection Option (Opt8x) and Cable Wiring” for RS-422/RS485 cable wiring. And also to Chapter “Serial Programming Tools” for Opt8J RS485 programming details.
2 2 Hardware Installation The installation of the C168P consists of hardware and software installation. The hardware installation is detailed in this chapter. The next chapter deals with the software installation for various operating systems.
Now you should do either the normal hardware installation (detailed in the later section, “Hardware Installation with IO-IRQ Utility”) or the quick hardware installation (detailed right in the next section, “Quick Hardware Installation”). The latter is provided to facilitate the hardware installation, only under the circumstances that: u u u Only one C168P board is allowed to install in a system. Windows NT and 95/98 are the only operating systems supported.
Hardware Installation 5. DO power OFF and then ON (or Reset) the PC. (Please cold start.) 6. Restart System (Windows NT/95/98). It is very important to keep the JP1 always short in this case. Without running the hardware configuration program, Io-irq.exe under DOS prompt, the software configuration program will automatically update the hardware settings of the board while updating the software settings. This saves the trouble doing hardware configuration.
1. Choose a PC that has DOS system inside. 2. Power off the PC. 3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC, one board at a time with JP1 open. + If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board. This is to prevent conflict between two boards with same default hardware settings.
Hardware Installation 1. Run the utility “Io-irq.exe” contained in the driver diskette to set up I/O address, IRQ and INT vector of the board. 2. Select “Smartio/Industio ISA Family” and press ENTER key.
3. Enter the CAP address of the C168P board to be configured. 4. Configure the following parameters as necessary. Port Index Indicate the port index for each port. I/O address Enter the base I/O address for each port, either sequentially or not. Avoid to conflicting with any other devices. IRQ Enter the IRQ, 2, 3, 4, 5, 7, 10, 11, 12 or 15, for each port, independently or not. Speed This field specifies the use of normal or high speed capability. Normal speed ranges from 50 bps to 115.2 Kbps.
Hardware Installation INT Vector Enter the interrupt vector I/O address for all ports. I/O address for interrupt vector is from 00000H to 0FFFFH. Interrupt vector is one byte of I/O address, in which each bit is used to indicate the occurrence of interrupt for corresponding port. To use interrupt vector, type in the hardware Interrupt vector I/O address. If not using interrupt vector, type 0 or leave blank as the interrupt vector. There are two modes for the C168P driver.

6 6 Troubleshooting Common C168P problems and possible solutions are listed below. If you still have problems, contact your dealer or Moxa for help. Or use the “Problem Report Form” at the end of this manual to report problems to your dealer at once for faster technical support. General Troubleshooting 1. The MOXA driver, while installing the driver, cannot detect the MOXA board. Hardware causes and solutions: a. The board is not installed or missing (absent). Please install it. b.
Software Causes and Solutions: a. C168P checks the line status (CTS) before it sends data out if the RTS/CTS flow control feature is set to “Enable” in the configuration or application program. Please refer to the “Connection Cable and Cable Wiring” chapter for proper wiring. Check the line status of the suspected port using the diagnostic LED indicators on the mini tester. b. Perhaps the application controlling the board is not correctly written according to the corresponding API of the operating system.
Troubleshooting To configure the board, you need to know the board’s Configuration Access Port (CAP) address. Because the CAP address is the only channel, via which the Ioirq.exe can access to the board. The following procedure instructs user to recover once the CAP is unknown. Step 1. Power off the PC. OFF Step 2. Install jumper onto the JP1 of the board. Install jumper JP1 Step 3. Power on the PC. Now the CAP address of the board will be 0xA700. ON Step 4. Execute Io-irq under DOS environment.
Step 8. Power off the PC. OFF Step 9. Remove the jumper on position JP1. Remove jumper JP1 Step 10. Power on the PC. ON Windows NT This section is specific for troubleshooting under Windows NT. For general problems and solutions, please see the previous section, “General Troubleshooting”. 1. After the system reboots, the error message “Another driver in the system, which did not report its resources, has already claimed the interrupt used by xxx.” appears in the Event Log.
Troubleshooting a. Some partial decoded network board may interfere with our board. Please avoid from using 0x300 as I/O address for those network boards. b. Check hardware configuration of C168P board by IO-IRQ.EXE. Then make sure the hardware configuration, including I/O addresses for each port, Interrupt Vector, IRQ, is identical to that of the driver. c. The I/O addresses may conflict with other devices, please change another set of I/O address such as I/O:0x280, Interrupt Vector:0x2C0. d.
c. The I/O addresses may conflict with other devices, please change another set of I/O address such as I/O:0x280, Interrupt Vector:0x2C0. d. The board(s) is not plugged properly.
