Description
RX+ is the positive half of the differential received data output from the to the host system. If the host system
uses a single ended received data input, that input should be connected to RX+ and RX- should remain open.
Ground connection to the XE0092. This signal provides the reference for the /OH input and /RI output. This
pin should be connected to the systems digital ground.
Ring is one wire of the two-wire telephone line connection (RJ11 Pin 4). FCC Part 68 Rules require a 1500 volt
isolation barrier between the telephone line and all other circuits. This isolation must be preserved throughout
the system. Xecom recommends 0.100 inch spacing between traces connected to Ring and all other conductors
to preserve this isolation
Tip is one wire of the two-wire telephone line connection (RJ11 Pin 3). The telephone company places a DC
"Battery" voltage across Tip and Ring on all public switched telephone lines. The XE0092 accept this line
battery voltage without regard to its polarity.
