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 ...

KB41 UR92 - Installation/Quick Start

The UR92 is simple to install and begin using in your new or current layout. 1. In most cases a UR92 should be situated near the physical center of a layout and will typically cover a circle of about 300+ feet (~100 meters) across, which will be adequate for most layouts. Some layouts may require additional UR92s for adequate signal coverage. 2. Connect the PS14 DC power supply to UR92 via the DC power jack on the side. The green and red LEDs should blink and then the red LED should stay on. 3. Connect the UR92 to your working LocoNet ...

KB16 Which Throttle works with which Universal Panel, UR90(IR), UR91(Simplex Radio), UR92 (Duplex Radio), or UR93 (Duplex Radio)?

The following chart indicates: Which Digitrax throttle (DT400, DT400R, DT402, DT402R, DT402D, DT500, DT500D, DT602, DT602D, UT4, UT4R, UT4D, UT6 & UT6D) Works with which LocoNet interface throttle panel (Universal Panel-UP3/UP5/UP7, UR90, UR91, UR92, and UR93) Under which types of communication (Tethered, IR Mode, Simplex Radio, or Duplex Radio).

KB703 UP5 Front Panel Installation

While it is possible to use RJ12 telco jacks as throttle jacks on LocoNet, the UP5 is much simpler to use and looks much more professional on the front of the layout. The UP5 is shipped as a kit that must be assembled.  You will need to attach the front panel to the circuit board using the screws provided as shown below before installing the entire unit on your layout.  If your front panel does not fit at a "perfect" 90 degree angle to the circuit board, this is will not affect the functionality of the unit.Make sure to line up the Track ...

KB701 UP5 Layout Installation and LocoNet Connection

1. The UP5 Universal Panel is designed for mounting on the fascia board of the layout. Cut a hole approximately 2.5” W x 1.5” H in the fascia board. Insert the UP5 through the hole with the face plate on the front of the fascia board. Attach the UP5 face plate to the fascia board with four #6 screws. Note: The UP5 uses the black screws to mount the front fascia plate.2. Connect the UP5 to LocoNet using pre-tested LocoNet cables. There are 2 LocoNet Jacks located at the back of the UP5 board for connecting LocoNet devices on your layout. ...

KB702 UP5 Power Supply and Track Indicator Connections

Hooking up the UP5's Power Supply (Optional but highly recommended to make sure LocoNet voltage is adequate to control large layouts)The optional power supply (PS14) can be connected to one or more UP and/or UR panels to provide additional power for LocoNet operation and for battery saving power to any Digitrax throttle that is plugged into any of the powered panels.1. Plug the PS14 into the DC jack located on the side of the UP5 circuit board.2. Connect the +Common point on each additional board (located between the two LocoNet jacks) to the powered board with 22AWG wire (Figure 2). ...

KB37 UR92 - Adding More UR92's

Adding UR92s will provide better signal coverage for complex layouts. If you are adding more than one UR92, be sure to connect all of the units before changing the Duplex Group name or channel number or you will have the units automatically re-negotiate these values with each addition. 1. Add the UR92(s) to your LocoNet. (See UR92 Installation articles, below.) 2. After adding extra UR92s, use the DT402D to turn OFF layout track power and then turn track power back ON. This forces all the UR92s to automatically negotiate a common and permanent single Duplex Group name and channel number. ...
