Contemporary Research 10 232-AMP+
RS-232 Cable Connections
Single 232-Amp+
RS-232 wiring for control or programming should only use pins 2, 3, 5. Cables with all pins wired can lock
out front-panel programming and data communication (Pins 4 and 9 are inputs).
Tuner/232-Amp+ Daisy-Chain
One 232-Amp+ and 232-series tuner can be controlled from one RS-232 control port. The 232-Amp+ will be
Unit 1, and the 232-series tuner will be set to Unit 2.
The flow of information will start at the tuner, which will respond to Unit 2 commands, passing on Unit 1
commands to the 232-Amp.
