Hardware Installation
Installing Smartio C168H/PCI consists of both hardware and software installation.
This chapter describes how to install the hardware, and in the next chapter, we discuss software installation.
The no-switch/no-jumper Smartio C168H/PCI board hardware configuration is straightforward, since the IRQ number and I/O addresses are automatically assigned by the PCI BIOS. This means that the board MUST be plugged in before installing the driver software.
Installing the Smartio C168H/PCI Board
Step 1: Turn off the PC and disconnect the power cable.
Warning!
Make sure your system is turned off before installing an expansion board. If you do not first shut down the computer, you risk damaging both the PC and the board.
Step 2: Remove the PC cover.
Step 3: Remove the slot cover bracket if there is one.
Step 4: Plug the Smartio C168H/PCI(s) into the PC’s free PCI expansion slot(s).
Step 5: Fasten the holding screw to fix the control board in place.
Step 6: Replace the system cover.
Step 7: Connect one of the connection boxes/cables (and adapter if required) detailed in the next section.
Smartio C168H/PCI User's Manual 2-1
Step 8: Turn on your PC. The BIOS will automatically assign the IRQ and memory address.
Note ! Each board must occupy one unique IRQ and one unique
memory address, assigned automatically by the PCI BIOS.
You may, however, use the PC's PCI-slot BIOS setup to manually assign a free IRQ number. This method, however, is usually not available to assign the memory address. The IRQ numbers that can be used are 2, 3, 4, 5, 9, 10, 11, 12, and 15. The I/O addresses that can be used range from 0x0000 to 0xFFFF.
Step 9: Proceed with the software installation, detailed in the next chapter,
Software Installation.
Installing Connection Option Opt8x
Use one of the following connection options to set up your Smartio C168H/PCI.
After that, connect your modem, serial printer, PC COM1/2, bar code reader, POS device, instrument, or any other serial device to the board’s DB25/DB9 connectors.

RS-485 Programming for Opt8J
If you intend to use Opt8J for RS-485 communications, follow the RS-485 programming guide given below, and refer to the chapter Connection Option (Opt8x)
and Cable Wiring for more Opt8J RS-485 operation details.
The Opt8J option only supports 2-wire half-duplex RS-485 communications. Data
+/
− pins are used for both data transmitting and receiving, depending on the RTS signal.
The port switch for each port should be set to the On position. The port is used for transmitting data if RTS is asserted and is used for receiving data if RTS is not
asserted.
This RTS scheme is suitable for any system that permits RTS control from within application programs. This includes Windows NT, Windows 95/98, DOS, and
UNIX.
How to transmit and receive data under Windows NT and
Windows 95/98
We recommend that you configure Smartio C168H/PCI ports as follows to acquire precise timing control when using RS-485 2-wire transmission.
There are 2 ways to control RS-485 2-wire transmission.
Solution 1
The following model is commonly used for RS-485 2-wire transmission. sio_SetWriteTimeouts(port, 0); sio_RTS(port, 1); sio_write(port, buff, 10); sio_RTS(port, 0); sio_read(port, buff, 10);
/* Set sio_write() into block mode */
/* Turn on RTS signal. The RS-485 port is ready for transmitting data. */
/* Write 10 byte characters in "buff". The function blocks until last character transmitted */
/* Turn off RTS signal. The RS-485 port is ready for receiving data. */
/* Read 10 bytes */
4-6 Smartio C168H/PCI User’s Manual
Serial Programming Tools
Solution 2
The PComm library contains a dedicated RS-485 function that integrates the functions given in solution 1 regarding sending data. sio_putb_x(port, buff, tick ); /* 1. Turn on RTS; ready for transmitting data.
3.
4.
Wait for tick time.
Turn off RTS; ready for receiving data. */
For more information about these functions, refer to the PComm library on-line Help file for Windows NT and Windows 95/98.

RS-422/485 Impedance Matching
When using RS-422/ 485 serial communications, an electrical signal travels through two different resistance junctions in a transmission line. The impedance mismatch that exists will sometimes cause signal reflection, distorting the signal. This in turn contributes to communication errors. The solution to this problem is to establish th e same im pedance at the line ends as in the line itself, by terminating them with resistors.
The resi stance of the termination resistor should equal the characteristic impedance of the tr ansmission line. Resistors sh ould be added near the receiving side.

Troubleshooting
In this chapter, we list several problems that could arise when using Smartio
C168H/PCI, and solutions you can follow to fix the problems. If you are unable to find a solution to your particular problem in this chapter, contact either a dealer or
Moxa for help. To receive a quicker response from your dealer, please use the
Problem Report Form at the end of this manual.
General Troubleshooting
1. While installing the driver, the Moxa driver is unable to detect the Moxa
PCI board.
Hardware causes and solutions:
A. The board is not installed. Please install it.
B. The board is not properly plugged into the system. If this is the case, re- plug the board into a 32-bit PCI slot. It may al so be the case that the slot you’ve chosen could be damaged. In this case, try other slots until you find one that works.
C. The motherboard does not have an available IRQ for the C168H/PCI board. In this case, enter the BIOS and make sure an IRQ is available in the PCI/PnP settings.
2. The Moxa board and driver are activated but cannot transfer d ata (either transmitting or receiving).
Hardware Causes and Solutions:
A. Check to see if the cable is wired correctly. Refer to the Connection
Option (Opt8x) and Cable Wiring chapter for correct cabling information.
Smartio C168H/PCI User's Manual 6-1
B. Either the cable or board could be defective. Try other ports, cables, and boards to verify this, or use PComm Diagnostic utility to test the Moxa board and port conditions. If Diagnostic reports an error, replace the faulty components.
Software Causes and Solutions:
C. The Smartio C168H/PCI board will check the line status (CTS) before transmitting data if the RTS/CTS flow control feature is set to Enable in either the configuration or application program. Refer to the Connection
Option (Opt8x) and Cable Wiring chapter for proper wiring specs, and check the line status of the suspected port using the diagnostic LED indicators on the mini tester.
D. The board controlling application might not be written correctly for the corresponding API of the operating system. To see if this is the case, run another application that you know is good, or use utilities provided by
Moxa. You can either use PComm Terminal emulator or HyperTerminal under Windows NT and Windows 95/98.
Windows NT
This section is specifically for troubleshooting under Windows NT. For general problems and solutions, 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.
This indicates that the Moxa board was found, but the IRQ that was assigned conflicts with another adapter’s IRQ setting. Check the PCI BIOS IRQ settings first, and then select an available IRQ.
2. After the system reboots, the error message “Cannot find any configured
Moxa Smartio/Industio series board!” appears in the Event Log.
Make sure the PCI board is seated firmly in the expansion slot.
3. The COM number of the Smartio C168H/PCI (Bus No=x Dev No=x,
Port1=COMx), with device number xx, conflicts with others.
6-2 Smartio C168H/PCI User’s Manual
Troubleshooting
Different boards have conflicting COM numbers. Change the M oxa board’s
COM number mappings.
4. Windows NT system panic (blue screen).
One possible reason is an IRQ or I/ O address conflict with other ISA Bus adapters, such as LAN and SCSI boards, or the system BIOS. Refer to the corresponding problem in the previous General Troubleshooting section for solutions.
Win dows 95/98
This section is specific for troubleshooting under Windows 95/98. For general problems and solutions, see the previous section, General Troubleshooting.
1. The system cannot find the Smartio C168H/PCI board!
- The boards are not properly plugge d in.
- The slot bein g used is defective. Try other slots until you find one that works.
- The board might be defective.
2. After the system reboots, the error message “C168H/PCI (BusNo=x,
DevNo=x, Port1=COMx) interrupt number is invalid!” appears.
This indicates that the Mo xa board has been found, but the IRQ that was assigned conflicts with another adapter. Make sure the Moxa board’s IRQ does not conflict with another adapter’s IRQ setting. Check the PCI BIOS IRQ settings and select an available IRQ for the Moxa board.

PCI
The 32-bit Smartio C168H/PCI board complies with PCI specifications 2.1.
Hardware configurations for IRQ and I/O addresses are automatically assigned by the PCI BIOS. Hence, you must first plug the board in before installing the driver software.
Unlike ISA slots, different PCI slots in the same PC may have different bus numbers and device numbers with respect to the PCI specifications. The same PCI board will have different system configurations if switched to a different PCI slot. This is
Smartio C168H/PCI User's Manual A-1
referred to as slot-sensitive or slot-dependent, and may apply to PCI slots in PCs with different motherboards and different device number sets. For example, some use 17, 18, 19, and 20 for identifying the respective PCI slots, but some use 11, 12,
13, and 14.
Due to slot-dependency, it is necessary to re-configure the driver software once the board is plugged into a different PCI slot.
Up to 4 Smartio C168H/PCI boards can be installed in one system. When installing more than one board, remember the order of boards to distinguish the installed boards from each other.

To increase the overall data throughput, special features such as on-chip FIFO and onchip hardware flow control are used to reduce the number of interrupts to the onboard CPU and to prevent loss of valuable data.
