RS-485 Programming for Opt8J
If you intend to do RS-485 communication with Opt8J, please follow the RS-485
programming guide below and also refer to Chapter “Connection Option (Opt8x)
and Cable Wiring” for more Opt8J RS-485 operation details.
The Opt8J supports only 2-wire half-duplex RS-485 communication. Data+/-
pins are served for both data transmitting and receiving, depending on the RTS
signal.
The port switch of each port should be set to On position. The port is for
transmitting data if RTS is asserted and for receiving data if RTS is not asserted.
RTS scheme is suitable for any system, including Windows NT and Windows
95/98, DOS, or UNIX, that permits RTS control from application programs.
How to transmit and receive data under Windows NT and
Windows 95/98
We recommend you to configure Smartio C168H/PCI ports as follows in order to
acquire precise timing control in RS-485 2-wire transmission.
There are 2 solutions to control RS-485 2-wire transmission.
Solution 1
The following model is common in RS-485 2-wire transmission.
sio_SetWriteTimeouts(port, 0);
sio_RTS(port, 1);
/* Set sio_write() into block mode */
/* Turn on RTS signal. The RS-485 port is ready for t
ransmitting data. */
sio_write(port, buff, 10);
sio_RTS(port, 0);
/* Write 10 byte characters in "buff". The function bl
ocks until last character transmitted */
/* Turn off RTS signal. The RS-485 port is ready for
receiving data. */
sio_read(port, buff, 10);
/* Read 10 bytes */

RS-422/485 Impedance Matching
For RS-422/485 serial communications, when an electrical signal travels through
two different resistance junctions in a transmission line, the impedance mismatch
will sometimes cause signal reflection. Signal reflection causes signal distortion,
which in turn will contribute communication errors. The solution to this problem is
to establish the same impedance at the line ends as in the line itself by terminating
them with resistors.
The value of the termination resistor should equal the characteristic impedance of
the transmission line. The resistors should be added near the receiving side.

6 Troubleshooting
Common Smartio C168H/PCI errors and possible corresponding solutions are listed
below. If the problem still cannot be solved by following solutions given, contact
dealers 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 PCI board cannot be detected by the MOXA driver while
installing the driver.
Hardware causes and solutions:
A. The board is not installed or missing (absent). Please install it.
B. The board is not properly plugged in the system. If that is the case, re-
plug the board in a 32-bit PCI slot this time. Sometimes the slot for
plugging the board is malfunctioned. In this case, try other slots until you
find a good one.
C. The motherboard does not have an available IRQ for the C168H/PCI
board. Please enter BIOS and make sure there are available IRQ in
PCI/PnP settings.
2. The MOXA board and driver are activated but cannot transfer
(transmitting/receiving) data.
Hardware Causes and Solutions:
A. Check if cable wiring is connected correctly. Please refer to the
“Connection Option (Opt8x) and Cable Wiring” chapter for correct
cable connection.
Smartio C168H/PCI User's Manual 6-1
Download from Www.Somanuals.com. All Manuals Search And Download.
B. The cable or the board are probably defective. Please try other ports,
cables or boards to verify it. Or use PComm Diagnostic utility testing
MOXA boards and port conditions. If Diagnostic reports error, replace
the malfunctioned faulty components.
Software Causes and Solutions:
A. 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
the configuration or application program. Please refer to the “Connection
Option (Opt8x) and Cable Wiring” chapter for proper wiring and check
the line status of the suspected port using the diagnostic LED indicators
on the mini tester.
B. The board controlling application might not be correctly written
according to the corresponding API of the operating system. To verify the
problem, please run another existing and known good application or the
utilities provided by Moxa. Such as Pcomm Terminal emulator or
HyperTerminal under Windows NT and Windows 95/98.
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.
This indicates the MOXA board is found, but the IRQ is conflicting with
another adapter. Please check the PCI BIOS IRQ settings first and then select
an IRQ that is available.
2. After the system reboots, the error message “Cannot find any configured
MOXA Smartio/Industio series board!” appears in the Event Log.
Please 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
Download from Www.Somanuals.com. All Manuals Search And Download.
Troubleshooting
The COM numbers for different boards are conflicting. Change the COM
number mappings for MOXA boards.
4. Windows NT system panic (blue screen).
The possible reason is an IRQ or I/O address conflict with other ISA Bus
adapters, like LAN and SCSI boards, or the system BIOS. Please refer to the
corresponding problem in the previous section “General Troubleshooting”
for solutions.
Windows 95/98
This section is specific for troubleshooting under Windows 95/98. For general
problems and solutions, please see the previous section, “General
Troubleshooting”.
1. The system fails to find the Smartio C168H/PCI board!
- The board(s) is(are) not plugged properly.
- The slot with boards plugging in is defective, please try another slot until you
find a good one.
- 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 MOXA board is found, but the IRQ is conflicting with
other adapter. Make sure MOXA board’s IRQ is not conflicting with other
adapter’s. Check the PCI BIOS IRQ settings and select an available IRQ for
MOXA boards.

PCI
The 32-bit Smartio C168H/PCI board complies with the PCI specifications 2.1.
Hardware configuration for IRQ and I/O addresses is automatically assigned by the
PCI BIOS. Hence, you must first plug the board before installing the software
driver.
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 switching to a different PCI slot,

which may be called slot-sensitive or slot-dependent. This may also apply to PCI
slots in PC with different motherboard, which may use 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 the slot-dependency, it is necessary to re-configure the software driver
once the board is plugged in different PCI slots.
Up to 4 Smartio C168H/PCI boards are allowed in one system. When installing
more than one boards, please remember the order of boards for distinguishing the
installed boards.
UART 16C550C
The UART chip 16C550C is an intelligent asynchronous controller supporting one
full duplex channel that simultaneously transfers data at 921.6 Kbps speed. To
increase the overall data throughput, special features such as on-chip FIFO and on-
chip hardware flow control are used to reduce the number of interrupts to the
onboard CPU and to prevent any loss of valuable data.
