DESCRIPTION
This Signal Conditioner allows analog voltage levels to be set and read
via its RS-232 serial port. Commands are provided to perform various
functions: an analog output, read an analog input, verify the communica-
tions link, programming, and enter calibration mode.

FEATURES
The
I/O
is capable of operating in a voltage output mode or a current out-
put mode. When operating in the voltage mode the analog input and out-
put range is 0.00 to 5.00 volts. In the current mode the analog input and
output range is 4.00 to 20.0 milliamps. See Selecting the Operating Mode.
