Chapter 1Introduction
Welcome to the CA Series of PC/104 communication modules, a multiport serial module for
industrial applications. 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.
The CA Series includes the following models:
CA-108:
8 ports, RS-232
CA-108-T:
8 ports, RS-232, wide temperature
CA-114:
