Quick Installation Guide
First Edition, May 2007
1. Overview
The CA Series multiport serial module provides serial port expansion for
embedded PCs. It is designed for PC/104 CPU boards that accept the
PC/104 expansion interface. Optional DB9 and DB25 cables are available
to connect different devices. The device drivers make full use of the
64-byte Tx/Rx FIFO and on-chip flow control, which allows up to 921.6
Kbps data transmission. Six different models are available as follows:
yCA-108: 8 ports, RS-232
yCA-114: 4 ports, RS-232/422/485
yCA-134I: 4 ports, RS-422/485 w/2 KV optical isolation protection
yCA-104 V2: 4 ports, RS-232
yCA-132 V2: 2 ports, RS-422/485
yCA-132I V2: 2 ports, RS-422/485 w/2 KV optical isolation protection

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 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:
Interface 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:
Interface 2-WIRE/4-WIRERS422/RS485
RS-422 --- OFF
4-wire RS-485 OFF ON
2-wire RS-485 ON ON
