5.6  LocoNet Wiring Components

Connecting the LocoNet components is easy to do.  Digitrax LocoNet devices
are connected using 6-conductor cables with RJ12, 6-pin connectors. 

Making your own LocoNet Cables is simple and cost effective.  We recom-
mend that you invest in a good quality set of crimpers.  Most Digitrax dealers
can supply or tell you where you can get the cable, plugs and crimpers you will
need.  Internet electronic suppliers also have these components available.

We recommend that you use the LT1 tester that came with your Super Chief
Xtra Set to test the cables to be certain they are good before installing them.
Many layout problems we see are related to LocoNet cables that were not built
or crimped correctly.

LocoNet can support a total cable length of up to 2,000 feet with no two
devices connected by more than 600 feet of cable.  LocoNet wiring is totally
free-form.  We do not recommend looping LocoNet back on itself.

5.7  Making LocoNet Cables

We use the following wiring convention for all LocoNet cables and connec-
tions: 

LocoNet cables are wired pin 1 to pin 1.  When you hold the plug with the tab
up and look into the end of the connector you will see the wires listed above
starting at the left side and moving to the right.  (This is sometimes called a
“reversing cable” in the telecom industry even though it really does not
reverse.)

5.8  Testing LocoNet Cables with an LT1

1. Disconnect the wire harness from the LT1. 

2. Plug one end of the LocoNet cable being tested into the LT1. 

3. Connect the other end to any powered Digitrax booster 

LocoNet Jack A

or

B.

Be sure you have at least one Digitrax throttle connected to LocoNet.

4. All four LEDs on the LT1 will light if the cable is good.  LEDs may not all
