3. Strip back the insulation on each of the 2 twisted pair wires
about .25".
4. Connect
one pair of wires to XMT+ and XMT- (transmit positive
and negative) on the terminal block, making careful note of which color
is positive, and which color is negative.
5. Connect the
other pair of wires to RCV+ and RCV- (receive
positive and negative) on the terminal block, again making careful note
of which color is positive, and which color is negative.
Ultimately, you will want to construct a two pair cross over cable that
makes a connection between the Model 1009s as shown below:
6. If there is a shield around the telephone cable, it may be
connected to "G" on the terminal block. We recommend connecting the
shield at the computer end only to avoid ground loops. A ground wire is
not necessary for proper operation of the Model 1009.
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.
9. Insert the strain relief assembly with the wire going through it
into the slot in the bottom half of the modem case and seat it into the
recess in the case. (If the telephone wire is too thin to be held by the
strain relief assembly, you will need to order a different sized strain
relief. Call Patton's Sales Department at (301) 975-1000.)
