8.Place the 2 halves of the strain relief assembly on either side of the telephone wire and press together very lightly (See Figure 9, below). 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.

11.Insert one captive screw through a saddle washer and then insert the entire piece through the hole in the DB-25 end of the case. Snap that side of the case closed. Repeat the process for the other side. This completes cable installation.

4.2CONNECTION TO THE RS-232 INTERFACE

Once you have configured the Model 1000 for DTE or DCE and

connected the twisted pair wires correctly, simply plug the Model 1000 directly into the DB-25 port of the RS-232 device. After doing so, remember to insert and tighten the two captive connector screws.

(Note: If you must use a cable to connect the Model 1000 to the RS-232, make sure it is a straight through cable of the shortest possible length—we recommend 6 feet or less).

4.3 OPERATING THE MODEL 1000

Once the Model 1000 is properly installed, it should operate transparently—as if it were a standard cable connection. Operating power is derived from the RS-232 data and control signals; there is no "ON/OFF" switch.
