Overview
The CA Series PC/104 module is designed to be used with PC/104 CPU modules or CPU cards
with the PC/104 expansion interface. Models are available for RS-232, RS-422, and RS-485, with
2, 4, or 8 ports. The serial ports are accessed through a 20 or 40-pin box header connector on the
module. DIP switches allow you to configure the I/O base address and INT vector of each port.
The industry-standard MOXA UART (16C550 compatible) is fully programmable. Built-in 15 KV
ESD protection protects devices connected to the serial network.
Package Checklist
MOXA performs a careful mechanical and electrical inspection of each module prior to shipping.
Your module should arrive in perfect electrical order, free of any marks or scratches. Please handle

Hardware Installation
Installing the CA Series module is easy. Before inserting the module into the PC/104 slot, you
must first configure the I/O base address, interrupt vector, IRQ, and serial interface (for select
models).
ATTENTION
Safety First!
To prevent damage to your system or board, make sure your embedded PC’s power is turned off
before installing your CA Series module.
Step 1: Shut off power to your embedded PC and to any peripheral devices. After shutting off
power, remove the cover of your embedded PC.
Step 2: Use the DIP switches on the module to select I/O base address, interrupt vector, IRQ, and
serial interface (for select models). Details for each model are provided later in this
chapter.
Step 3: Insert the module firmly into the embedded PC’s PC/104 slot.
Step 4: Screw the control board in place.
Step 5: Connect the cables.
Step 6: Power on the embedded PC.

I/O Base Address
Use DIP switch SW1 to set port 1’s I/O base address. The other ports will be configured
automatically. The default I/O base address is 0×180 and allows settings from 0×000 to 0×3FF.
Some popular settings are provided below:
A3 A4 A5 A6 A7 A8 A9
8 1 2 4 8 1 2 Hex
ON ON ON ON ON ON ON 0×000
ON ON ON ON ON ON off 0×200
ON ON ON ON ON off off 0×300
ON ON ON ON off off off 0×380
ON ON ON off off off off 0×3C0

off off off ON ON ON ON 0×038
off off off off ON ON ON 0×078
off off off off off ON ON 0×0F8
off off off off off off ON 0×2F8
For example, an I/O base address of 0×180 should be set as follows:
A3 A4 A5 A6 A7 A8 A9 Hex
ON ON ON ON off off ON 0×180
ON DIP
1234567
A3 A4 A5 A6 A7 A8 A9
081
= on, = off
The other serial ports will be set automatically to 0×188, 0×190, 0×198, etc.

Interrupt Vector
Use DIP switch SW2 to set port 1’s interrupt vector. The default interrupt vector is 0×1C0, with
SW2 set as follows:
A3 A4 A5 A6 A7 A8 A9 Hex
ON ON ON off off off ON 0×1C0
ON DIP
1234567
A3 A4 A

Serial Interface
For the CA-114, use S3, S4, and S5 to select the serial interface as follows:
Mode S3 S4 S5
RS-232 --- --- ON
RS-422 --- ON off
4-wire RS-485 ON off off
2-wire RS-485 off off off
For the CA-134I, CA-132 V2, and CA-132I V2, use the 2-WIRE/4-WIRE and RS-422/RS-485
DIP switches to select the serial interface as follows:
Interface 2-WIRE/4-WIRE RS422/RS485
RS-422 --- OFF
4-wire RS-485 OFF ON
2-wire RS-485 ON ON
IRQ
Before selecting an IRQ, please enter the PC’s BIOS and reserve a dedicated IRQ for the module.
On the module, the IRQ is set by a jumper. Before inserting the module into the PC/104 slot, use
the jumper to select an IRQ (3, 4, 5, 6, 7, 9, 10, 11, 12, or 15).
