Introduction
The term Industio stands for smart multiport serial I/O solution for industrial
applications. The
CI-134IS
, are designed for 16-bit ISA/EISA bus. They offer 4 independent RS-
Industio CI-134 Series boards, including CI-134, CI-134I and
422/RS-485 serial ports. It offers reliable communication link over a longer distance
(4000ft). It is best suitable for industrial environment.
Connections with
point-to-point full-duplex or multidrop half-duplex are available
to meet your needs. Each port can connect up to 64 devices, such as data acquisition
equipment and many other serial devices, to the PC and its compatible systems in a
multidrop environment.

Automatic Data Direction Control for RS-485
To ease the 2-wire RS-485 half-duplex control, Automatic Data Direction Control
intelligence is built on each
interference. Hence, the applications can manage the RS-485 port without extra code
to control the half-duplex protocol.

Termination Resistors Ready for RS-422/RS-485
Termination Resistors are already installed on the Industio CI-134 boards and no
more headaches for finding proper resistors and connecting them for impedance
matching problem. More details are in chapter, “Connection Cable and Cable
Wiring”.
Surge/Isolation Protection
To meet the demand of high reliability in industrial environment and to prevent the
boards from damage caused by lighting or high potential voltage, an optical isolation
option (2KV) and surge block option (2KV) are available. This is critical to harsh
environment such as factory.
ASIC Design, Compact Size
The Industio CI-134 Series is equipped with MOXA customer-designed ASIC chip,
which replaces lots of conventional IC and hence reduces the board to half-size,
increase the operation performance, and lower the failure rate of the board. Full range
of I/O addresses and IRQ numbers are available. In addition, with
EEPROM
or switch. These features make each port on the board truly independent to any other
port and thus compatible with most existing non-intelligent boards. Because the
family is so flexible in hardware configuration, it is compatible virtually with all
kinds of other manufacturer's non-intelligent multiport boards using 16550 UART.
for storing the configuration data, the family is designed without jumper
CAP Address
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,
read and write the on-board EEPROM for configuration information through the
CAP (Configuration Access Port) address. The CAP address is the only channel via

How to Do Quick Hardware Installation
1. Short the jumper JP1 on the upper-left corner of the board.
2. Plug the board in PC with the desired system installed (Windows NT or 95/98),
which is powered off in advance.
3. Do software (driver) installation, detailed in the next chapter.
This is to specify the desired I/O address, IRQ and INT Vector in the software
configuration panel, no matter what hardware settings are on the board. The
software configuration program will automatically update the hardware settings.
After this, users already complete the whole installation.
4. Shutdown the system (Windows NT or 95/98).
5. Do power off and then on (or Reset) the PC. (Please cold start.)
6. Restart System (Windows NT or 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. However, remember to

Cable and Cable Wiring”
The
Industio CI-134 Series supports only 2-wire half-duplex RS-485
communication
depending on the mode selected: either Automatic Data Direction Control or By RTS mode.
Automatic Data Direction Control Mode (Recommended)
Automatic Data Direction Control scheme is the best solutions for RS-485
applications. The mode switch for the port should be set to
use Automatic Data Direction Control Mode.
Under this mode, no extra code is required to control the data transferring (data
transmitting and receiving), which is automatically managed with the intelligent
hardware mechanism. That is,
as RS-232/RS-422 programming

By RTS Mode (For back-compatibility)
If the mode switch for the port is set to OFF position, By RTS Mode is used. The port
is ready for transmitting data if
if
RTS signal is not asserted.
RTS scheme is a traditional way and suitable for most system, including Windows
NT, Windows 95/98 and DOS, or even UNIX, that permits RTS control from
application programs. This mode should be compatible with most of the alreadymade RS-485 applications.
How to transmit and receive data for Windows NT, 95/98 & DOS

Serial Programming Tools
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); /* Set sio_write() into block mode if for
Windows NT and Windows 95/98 */
sio_RTS(port, 1); /* Turn on RTS signal. The RS-485
port is ready for transmitting data. */
sio_write(port, buff, 10); /* Write 10 byte characters in "buff".
The function blocks until last
character transmitted */
sio_RTS(port, 0); /* Turn off RTS signal. The RS-485
port is ready for receiving data. */
sio_read(port, buff, 10); /* Read 10 bytes */
Solution 2
There is a dedicated RS-485 function in PComm or API-232 library. It
integrates the above functions of solution 1 regarding sending data as one.
sio_putb_x(port, buff, tick ); /* 1. Turn on RTS and ready for

2. Send data.
3. Wait for tick time.
4. Turn off RTS and ready for

Impedance Matching and Termination Resistors
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.
Industio CI-134 already installs the resistors on board for your convenience,
indicated as follows. The value of the termination resistor should equal the
characteristic impedance of the transmission line. Resistors should be added near the
receiving side.

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.
The board is not properly plugged in the system. If that is the case, re-install
the board and make sure that it fits well in a 32-bit slot this time. Sometimes
the slot for plugging the board is bad. In this case, try other slots until you find
a good one.

2. The MOXA board and driver are activated but cannot transfer
(transmit/receive) data.
Hardware Causes and Solutions:
a. Check for wrong cable wiring. Refer to the “Connection Cable and Cable
Wiring” chapter for precise pin outs of the connector type you are using.
b. The cable or the board is defective. You may use other ports, cables or boards
to verify. In addition, the
Windows 95/98 is good for testing MOXA boards and port conditions. If
Diagnostic reports error, replace the faulty components.

Industio CI-134 Series User’s Manual 6-1
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,
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
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
d. 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.
Industio CI-134 board may malfunction. Please return for repair.
4 for how to solve this problem.
Pcomm “Terminal
If any existing board has the same I/O address as 0x180, the
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
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.
