Once the unit has been opened, you will be able to see the
terminal blocks located at the rear of the PC board.
2. Strip the outer insulation from the twisted pairs about one inch
from the end.
3. Strip back the insulation on each of the 2 twisted pair wires
about .25".
4. Connect one pair of wires in the telephone cable to "XMT"
(Transmit) on the terminal block, being careful to observe the polarity.
(The wire connected to "XMT+"must be connected at the other end of
the telephone line to "RCV+" in the other unit and the wire connected to
"XMT-" must be connected at the other end of the telephone line to
"RCV-" in the other unit).
5. Connect the other pair of wires in the telephone cable to "RCV"
(Receive), again being careful to observe the polarity. (The wire
connected to "RCV+" must be connected at the other end of the
telephone line to "XMT+" in the other unit and the wire connected to
"RCV-" must be connected at the other end of the telephone line to
"XMT-" in the other unit).
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 these units.
7. When you finish connecting the wires to the terminal block, the
assembly should resemble the diagram below:
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.
