1 Introduction Chapter 1 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.
CA Series User’s Manual Introduction 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.
