Description
RS-232 to RS-232 / isol Repeater
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 provides 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 the I-7551 is located in the input and
output interface circuit. In other words, the I-7551 is 3-way isolation RS-232 to RS-232 repeater.
