Overview
CA-132/132I is a PC/104 module that supports the RS-422/485 serial interfaces, and can be used with
PC/104 CPU modules or CPU cards that accept PC/104 expansion modules. CA-132/132I has two
independent serial interfaces, which are accessed through RJ45 connectors. You can configure both ports
for the RS-422 or RS-485 interfaces by DIP switch. The module’s industry-standard MOXA UART
(16C550 compatible) is fully programmable. Moxa has implemented its patented ADDC™ technology
for RS-485 automatic direction control, so there is no need to change jumpers to switch the module
between driver and receiver. The built-in 16 KV ESD surge protection protects other devices connected
to the RS-485 network.

Hardware Installation
RS-422/485 Interface Settings
You can use DIP switches SW3 and SW4 to configure each port individually for either RS-422
(4-wire) or RS-485 (2/4-wire) interface with termination resistor (TR) on/off (120 ohm). SW3
configures Port 1, and SW4 configures Port 2, as shown in the switch setting diagrams below.
SW3 (P1)
SW4 (P2)
The following diagram shows how to use the DIP switches to configure each port for either RS-422
(4-wire) or RS-485 (2/4-wire) interface with or without termination resistor.
I/O Base Address & Interrupt Vector Settings
CA-132/132I Series have two 7-switch DIP switch panels, named SW1 and SW2. Panel SW1 is for
I/O Base Address setting, and SW2 is for Interrupt Vector setting. Once you configure Port 1’s I/O
Base Address and Interrupt Vector, the settings for the other ports will be configured automatically as
well. You can choose base addresses from hex 000 to 3FF. The default settings are CH#1 (Hex 180)
for I/O Base Address and 1C0 for Interrupt Vector settings.
Example:

IRQ Setting
CA-132/132I Series has a jumper selectable function for you to configure IRQ settings. Before you
insert a CA-132/132I board into the PC/104 interface, you need to choose an available jumper from 3,
4, 5, 6, 7, 9, 10, 11, 12, or 15 to configure the IRQ setting.
Initial Inspection
Before we ship CA-132/132I products, we first perform a careful mechanical and electrical inspection
of these serial boards. Products should be free of any marks or scratches and in perfect electrical order
when customers receive them. Handle these boards only by their edges, since the static charge from
your body may damage the integrated circuits. Always keep the boards in their anti-static package
whenever they are not installed. You can also use this package to return the board should it need to be
repaired.

Port number:
This is actually the port ID of each port. The application software will refer to
the port by its port number (ID). Duplicated port number is not allowed. That
is, each MOXA serial port is referred to as port number in terms of serial
programming.
You may map the port number range to the one you prefer between 0 and 127
as long as no port number overlapping condition or port number undefined
condition occurs. Generally, you should take the convenience of programming
into consideration when specifying the port numbers for the board.
TxD buffer size: The transmission (output) buffer allocated in the system for each port.
RxD buffer size: The receiving (input) buffer allocated in the system for each port.
F5: Group Edit: This is a convenient function that helps you edit the configuration of several
ports at one time as a group.

PComm, a professional serial comm tool for PCs, is a software package that runs under Windows
NT/2000/XP/2003 and Windows 95/98/Me. PComm provides:
#
A powerful serial communication library for easy programming in the most popular programming
languages. The serial communication library is useful for developing applications for data
communications, remote access, data acquisition, and industrial control under Windows
NT/2000/XP/2003 or Windows 95/98/Me. It is a simpler solution compared to the more complex
Windows Win32 COMM API.

PComm Installation
To install PComm, run \Setup.exe from the diskette enclosed in the package. Please note that the PComm
diagnostic and monitor utilities are for MOXA boards only; these two utilities will not work with other
manufacturer’s serial boards.
PComm Programming Library
The serial communication library assists you in developing serial communications programs for any
COM port that complies with Microsoft Win32 API. It facilitates the implementation of multi-process
and multi-thread serial communication programs and hence remarkably reduces development time.
This serial communication library provides a complete function library and sample programs for Visual
C++, Visual Basic, and Delphi. To view detailed function descriptions and sample programs, click on [Start]
" [Program] " [PComm Lite] " [PComm Lib Help], [PComm Porting Notes] or [PComm Programming
Guide], or refer to the sample programs in the PComm directory.
Utilities
In this section, we give brief descriptions of each utility. For more information about these utilities, see
the on-line help from the software diskette.
Diagnostic (for MOXA boards only)
A convenient diagnostic program, ONLY for MOXA boards and ports, provides internal and external
testing of IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD, etc. It allows the user to check the
function of both software and hardware.
To run the Diagnostic program, click on [Start]"[Program]"[PComm Lite]"[Diagnostic].

Monitor (for MOXA boards under Windows NT Only)
A useful port status monitoring program allows you to monitor data transmission of selected
MOXA COM ports. It monitors data transmission/receiving throughput, and communication line
status, with data updated and displayed on the screen at regular time intervals. Click on a specific
port to see a graph of the current communication parameters and status of that port.
To run the Monitor program, click on [Start]"[Program]"[PComm Lite]"[Monitor].
Terminal Emulator
Terminal Emulator can be used to connect to various ports to see if data transmission is
functioning correctly. Terminal Emulator features multi-windows, and supports VT100 and ANSI
terminal types. You can transfer data interactively, send patterns periodically, and transfer files
using ASCII, XMODEM, YMODEM, ZMODEM, and KERMIT protocols.
To run Terminal Emulator, click on [Start]"[Program]"[PComm Lite]"[Terminal Emulator].

RS-485 Programming
If you intend to do RS-485 communication with CA-132/132I Series boards, please follow the
RS-485 programming guide below and also refer to the chapter, “Connection Cable and Cable
Wiring”, for more RS-485 operation details.
The CA-132/132I Series supports only 2-wire half-duplex RS-485 communication. Data+/- pins
are used for both data transmitting and receiving, depending on the mode selected: either
Automatic Data Direction Control or By RTS.
By RTS Mode (For back-compatibility)
If the mode switch for the port is set to the OFF position, By RTS Mode is used. The port is ready
for transmitting data if RTS signal is asserted and ready for receiving data if RTS signal is not
asserted. RTS scheme is the traditional method, and is suitable for most systems, 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 existing RS-485 applications.
How to transmit and receive data for Windows NT, 95/98
We recommend you to configure CA-132/132I Series 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) /* 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)
sio_RTS(port, 0)
/* 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. */
sio_read(port, buff, 10)
/* Read 10 bytes */
Solution 2
There is a dedicated RS-485 function in PComm 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 transmitting data.
2. Send data.
3. Wait for tick time.
4. Turn off RTS and ready for receiving data. */
For more information on these functions, please refer to PComm library on-line Help file for
Windows NT and Windows 95/98 respectively.
