1. Introduction
The I-7551 Photo coupler provides a complete full-duplex (including control
signal) electrical isolation channel between two RS-232 devices. This
isolation is an important consideration if a system uses different power
sources, has noisy signals or must operate at different ground potentials.
The I-7551 has the option of reconfiguring which control signal is used.
CTS can be selected instead of DSR and RTS instead of DTR. The I-7551
incorporates two DC-to-DC converters; the isolation site of I-7551 is located
in the input and output interface circuit. In other words, I-7551 is three- way
isolation RS-232-to RS-232 converter.
