The receiver is designed to sense the signal generated by a similar

transmitter, and is electrically isolated from all other circuitry on the

module. It consists of an opto–isolater circuit with an input and return

connection at the RS–232 connector. All other signals on the RS–232

connector are driven and received by standard RS–232 interface circuits,

and have a maximum drive capability of 50 feet.
