Patton electronic 1020S - Manual (Page 6)

4. Connect one pair of wires to the two XMT (transmit) poles on
the terminal block, making careful note of which colors you
use. The Model 1020 is not polarity sensitive, so either wire
may connect to either pole.
5. Connect the other pair of wires to the two RCV (receive) poles
on the terminal block, making careful note of which colors you
use. The Model 1020 is not polarity sensitive, so either wire
may connect to either pole.
Ultimately, you will want to construct a two pair crossover
cable that makes a connection with the two Model 1020s as
shown below:
6. If there is a shield around the telephone cable, it may be
connected to “G” on the terminal block. To avoid ground
loops, we recommend connecting the shield at the computer
end only. A ground wire is
not necessary for proper operation
of the Model 1020.
7. When you finish connecting the wires to the terminal block, the
assembly should resemble the diagram below:
RCV G XMT
8. Place the 2 halves of the strain relief assembly on either side
of the telephone wire and press together very lightly. Slide the
assembly so that it is about 2 inches from the terminal posts
and press together firmly. If your cable diameter is too small
or too large for our strain relief, please contact our technical
support. We have strain relief assemblies to accommodate
most cable diameters.
9. Insert the strain relief assembly with the wire going through it
into the slot in the bottom half of the modem case and set it
into the recess in the case.
