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:
XMT |
| RCV | } One Pair |
XMT |
| RCV | |
G | To Shield (Optional) | G | } One Pair |
RCV |
| XMT | |

| XMT |
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.
