4.0 INSTALLATION & OPERATION
Once the Model 1205 is properly configured, installation and
operation are very simple. The Model 1205 draws all necessary
operating power from the V.35 interface, thus no AC power or batteries
are required. There is no power switch. Just like a cable, the unit
should operate transparently when the host devices are turned on and
communicating. Follow these installation and operation instructions.
1. Configure the Model 1205 for your specific application according to
the instructions in
Section 3.0
of this manual.
2. Turn off the host (DTE) devices to which the Model 1205 is to be
connected.
3. If one of the host devices has an EIA-530 port, you may plug the
Model 1205 directly into that device. Then connect the Model 1205
to the other host device using a multipair cable* not to exceed 300
feet in length.
4. If neither host device has an EIA-530 port, you will need a multipair
adapter cable* for each end of the Model 1205. The total cable
length must not exceed 300 feet. See Figure 5 above.
5. Turn on both host devices. They should communicate normally as
if connected by a simple cable. If they do not communicate
properly, check the configuration of the Model 1205 and each host
device (Who is supplying the clock?, etc.). If problems are still
detected, call Patton Technical Support a:
