ControlNet TRANSCEIVER
The third signal receiver function (SIG) provides a
scaled analog output which is proportional to the
differential voltage between XF1 and XF3. This
output can be used for diagnostic purposes.

These devices are single-channel circuits with one
transceiver for single node operation or distributed
stand-alone applications.
The pull-or-pull transmitter circuit is designed to sink
current from a center-tapped transformer, providing
galvanic isolation from the shared bus.
These devices incorporate a differential receiver
