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.
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 (see Figure 10, below).

10. TIP the top half of the case as necessary to place it over the
strain relief assembly (see Figure 11, below). Do not snap the case
together yet.
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.
4.2 CONNECTION 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.
