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).
Most Digitrax dealers can supply or tell you where you can get the cable, plugs
and crimpers you will need. Mail order electronic suppliers also have these
components available.
4.12 LocoNet Throttle Jacks & LocoNet Connection Jacks
Digitrax LocoNet devices are connected using 6 conductor LocoNet cables. All
LocoNet devices have LocoNet Connection Jacks that allow you to daisy chain
the network around the layout.
Some Digitrax devices like the Universal Panels also have LocoNet Throttle
Jacks. The Throttle Jacks should not be used for connecting LocoNet devices
that will be daisy chained beyond themselves or that use rail sync. You can use
these jacks for throttles, DS54s and PM42s. Consult the installation instructions
for the particular device you are installing to determine whether it can use the
Throttle jacks or if a Connection jack is necessary.
All Digitrax throttles are memory walkaround throttles, some are equipped
with infrared LEDs and others are radio throttles. Even if you use wireless
throttles, you will still need to install at least one or two LocoNet throttle jacks
on your layout. Any RJ12 6 conductor phone jack can serve as a LocoNet
throttle jack. The problem with using RJ12 telephone style jacks is that you
will have to wire them and secure them to the layout so that they don’t come
loose. The Digitrax Universal Panel UP5 (or UR91), included with your Super
Empire Builder Set, provides a simple plug and play alternative to wiring RJ12
telephone style jacks around the layout. This fascia mounted panel provides 2
RJ12 LocoNet throttle jacks , as well as “Track Status” indicator on the front
panel. The back of the panel provides 2 RJ12 LocoNet connection jacks for
daisy chaining to the next LocoNet device on the network. An additional RJ12
throttle jack is provided on the side of the UP5 for connecting additional throt-
tles or LocoNet devices such as PM42s and DS54s. The UP5 gives a profes-
sionally finished look to your layout fascia. UP5, UR90 (infrared receiver) &
UR91 (radio receiver) all provide additional LocoNet Throttle Jacks for your
system.
