KB673 DS64 Stationary Decoder-Power & RailSync

  Can a DS64 be powered from the LocoNet RailSync lines? No.  The LocoNet cable is used only for LocoNet commands. The DS64 must be powered via the rear modular connector (12-14 volts AC or DC) OR via the AUX power 12-16 volts DC using AX1(-) and AX2(+) on the circuit board at the front of the unit. It is also possible for the DS64 to get it's power from the track hooked to Trk A and Trk B terminals, but experience has proven that this power source may not be reliable in certain situations.  NOTE: Use only the rear power jack or ...

KB714 Loconet Overview

LocoNet is Digitrax's method of communication between LocoNet compatible devices on a model railroad layout.  LocoNet compatible devices are designed to work together on the network, and in some cases can also accept DCC commands from  the track, but often go beyond the scope of simple DCC train control.   LocoNet is a peer-to-peer Ethernet type multiple access network.  Because of its design architecture, it is very robust and powerful.  Layout implementation is simple and wiring is free form with minimal limits. LocoNet is designed to run an unshielded 6 conductor ribbon cable.  Digitrax recommends using flat, six-conductor telephone wire ...

KB613 Throttle Jacks vs. LocoNet Jacks

The jacks on the front and sides of the UP5, UR92, UR91, UR90, and LNRP front panels are Throttle Jacks and should only be used for connecting throttles to LocoNet.  They should not be used to connect to other LocoNet devices.  The jacks on the back of these units are LocoNet Jacks that are used for connecting LocoNet devices to the network.  Technically speaking! These units were designed to have the FRONT jack's second Railsync differential signal run as a diode-or'ed power source (for throttles).  This means that some cable orientations and power loads could cause unexpected operations in downstream LocoNet devices ...
