Description

The PM318 Expander allows multiple listeners to be connected to a single talker. The PM318 takes three either a single-ended RS-232 or a differential RS-422 signal. It conditions and buffers the input signal to provide 8 single-ended RS-232 outputs and 8 differential RS-422 outputs. It also provides up to 1kVRMS input-to-output-to- power isolation using optical and transformer technology.
