6-2 Industio CI-134 Series User’s Manual
Software Causes and Solutions:
a. For RS-422 mode, Industio CI-134 Series 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.
b. Perhaps the application controlling the board is not correctly written
according to the corresponding API of the operating system. To verify, please
run an existing and known good application or the provided utilities by Moxa.
For example, under Windows NT and Windows 95/98,
Pcomm “Terminal
emulator” or “HyperTerminal” utilities are good for testing the COM ports.
3. Why the DOS utility IQ-IRQ can not access Industio CI-134 to configure?
There are several reasons that may lead to this trouble:
a. The user forgets or does not know the Configuration Access Port (CAP) of the
board. See next problem
4 for how to solve this problem.
b. The CAP of the board conflicts with other add-on boards’ I/O address. Please
change other add-on boards’ I/O address to avoid the conflict.
c. The
Industio CI-134 board is not plugged in a right or good slot. Please plug
the board in a good 16-bit ISA slot.
d. The
Industio CI-134 board may malfunction. Please return for repair.
If any existing board has the same I/O address as 0x180, the
default CAP address,
or the 1st port's I/O address, you must try to avoid the conflict by doing either one
the following.
a. Install a jumper (short) at position JP1 on the upper-left corner of the board.
This will force the CAP address to 0xA700.
b.
Change or disable the existing board's I/O address.
4. What to do if user forgets or does not know the Configuration Access Port
(CAP) address of
Industio CI-134?
The Industio CI-134 multiport boards are designed without jumper or switch, so
the configuration is completed only by DOS utility Io-irq.exe.
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 Io-
irq.exe can access to the board.
