SLLS770A–JANUARY 2007–REVISED FEBRUARY 2007
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 incorporate a differential receiver
(RX) with the 120 mV sensitivity needed by
ControlNet industrial applications.
TXBAR
A secondary receiver (CD) detects the presence of a
valid positive differential signal.
