The CA-132/132I PC/104 modules are reliable, high performance,
multiport serial communication solutions that have 2 RS-422/485
ports, and can be used with PC/104 CPU boards that accept the
PC/104 expansion interface. Optional DB9 and DB25 connection cables
are available for connecting to serial devices, and the CA-132/132Is’
versatile driver support makes the modules suitable for a wide range
of applications.
