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.

10.Place the top half of the case as necessary to slide it over the strain relief assembly. Do not snap the case together yet.

11.Insert one captive screw through a saddle washer. 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 connected the twisted pair wires correctly, simply plug the Model 1025 directly into the DB-25 port of the RS-232 device. After doing so, remember to insert and tighten the two captive connec- tor screws.

4.2.1 CONNECTION TO A “DTE” DEVICE

The Model 1025 is wired as a DCE, and therefore wants to plug into a DTE such as a terminal, PC or host. Because the Model 1025 is interface powered, a direct connection to the RS-232 DTE port is most desirable. If you must use a cable to connect the Model 1025 to the DTE port, make sure it is a straight through cable of the shortest possi- ble length—we recommend 6 feet or less.
