3 Electrical and Mechanical Interface
The CXM539 is powered from a single input voltage that can range
b6 V and +15 V. Current consumption is 100 ma. Two serial
interfaces are present; one that uses RS-232 levels and one that uses TTL
levels. The baud rate is user programmable and can be set at the following
values: 300, 1200, 2400, 4800, 9600, 19200, 38400, and 72800. The data
words employ 8 bits with one stop bit and no parity.
A female 9 pin D connector is used to provide an electrical interface to the
CXM539 system. The Pin out of this connector is as follows:
