Chapter 1 Introduction
Welcome to MOXA CA-132/132I Series of advanced 2-port RS-422/485 PC/104 communication
modules, a new industrial multiport serial board solution. Both ports of CA-132/132I can be
configured by DIP Switch for either the RS-422 or RS-485 interface, and with its PC/104 standard, the
CA-132/132I Series is compatible with any PC/104 CPU module or CPU card that accepts PC/104
expansion modules.

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
The hardware installation of CA-132/132I serial boards is easy to carry out. Before you insert
CA-132/132I into the PC/104 interface, you must first configure the RS-422/485 setting, I/O Base
Address & Interrupt Vector, and IRQ Settings. Follow the detailed steps given below to install the
CA-132/132I serial board in your computer.
Step 1: Configure the RS-422/485 setting, I/O Base Address & Interrupt Vector, and IRQ Settings
(see details below).
Safety First!
To avoid damaging your system and boards, make sure your PC’s power is turned off before installing
your CA-132/132I board.
Step 2: Turn your PC’s power off, and also shut off the power to any peripheral devices, and remove
the PC’s cover.
Step 3: Insert the CA-132/132I serial board into the PC/104 interface slot.
Step 4: Fasten the holding screw to fix the serial board in place.
Step 5: Replace the PC’s cover.
Step 6: Power on the PC.

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:

When you wish to configure your Port 1’s I/O base address to 180, the DIP switch settings of panel
SW1 should be as follows:
When you wish to configure your Port 1’s INT Vector to 1C0, the DIP switch settings of panel SW2
should be as follows:
On On On Off Off Off On
0 ×1C0
The following diagrams show the DIP switch settings of panel SW1 and panel SW2 when the I/O base
address is configured to be 180, and the INT Vector is configured to be 1C0.
The diagram shown above is SW1 for
setting I/O Base Address.
The diagram shown above is SW2 for
setting INT Vector.

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.
