UR92 Duplex Radio Transceiver

   Setting the Duplex Group Channel:  1. Connect the DT402D to the front RJ12 jack of any UR92 on the LocoNet.2. On the DT402D press the opTN key and then the EDIT key.  The Group Channel Numer (11-26) will now show in the lower left hand side of the display. 3. Use the Y/+ key to change to a higher channel in the available range of 11 through 26.  The N/- key will change to a lower channel.  4. Press the ENTER key to update the current displayed characters as the new UR92 Duplex Group Channel. To skip making any changes, ...

Setting Duplex Group Name You can use the DT402D to edit the UR92’s Duplex Group name to one you prefer. Note that this change is optional, and the UR92 factory default will always work out of the box.   The Duplex Group Name is stored in non-volatile memory and is remembered even when unpowered or disconnected from your system.   You should have all UR92s connected prior to changing the Group name or they will automatically renegotiate and may change the preferred name to a default.  1. Connect the DT402D or DT500D to the front RJ12 jack of any UR92 ...

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. ...

Resetting Factory Defaults You are unlikely to encounter a problem that will require a factory reset. One such instance may occur if you set a password for your Duplex Group name and forget what it is. Resetting to factory default condition is an easy way to correct the situation. Note: If you have more than one UR92 in your layout, you will want to disconnect all of them to do a full factory reset on each unit as follows. Once they have been reset, reconnected to your LocoNet, and allowed to renegotiate a common Group name; you can change the ...

Troubleshooting Your Installation To get the best performance out of your duplex radio installation, walk around the layout and check Duplex operation to ensure complete signal coverage. Depending on the layout size and geometry and surrounding materials it is often possible to move the UR92(s) to better cover dead-spots. Experimenting with UR92 location usually will quickly provide a position that is best for most layouts. Note that DT402D orientation and your body position may also affect range and reception. On very large layouts or layouts with problem areas, it is possible to add more than one UR92. Adding extra units ...

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 ...

Follow these simple instructions to determine the best location/s on your layout for installing your UR panels for the best possible infrared or radio reception. With LocoNet, you can use Infrared, Duplex Radio and Simplex radio individually or in any combination on your layout.You'll need to be able to observe whether your command station is receiving commands from the UR panels when you are installing infrared or radio receivers and transceivers.  Your Digitrax command station makes it easy to determine when the system is receiving a signal and when it is not.  You can observe the NET LED and the Track Status Indicator or your ...

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 ...

Configuring the Duplex Group Password The UR92 ships from the factory with the default Duplex Group Password of 0000, the value that disables password requirements. You may have an occasion when operating in a multisystem environment when you may want to restrict access to your layout and operating system via a tetherless Duplex Throttle. The password for your Duplex Group may be activated or changed: 1. Plug a DT402D or DT500D throttle into the UR92. 2. Press the EXIT key. 3. Press the OPTN key then the EDIT key. 4. Enter a 4-digit number using the numbers on the keypad ...

  Q:  Can I mix UP-5s with Radio and IR panels? I want to upgrade slowly and still use the 400 throttles and the UT throttles while I mail them in to you one at a time for conversion to radio. A:  Yes, and you can continue to use the UP5's after conversion to radio; for instance, if you have visitors who bring their own Digitrax non-radio throttles. That's the real genius of LocoNet, since you can add to your railroad in any way. Note that you will need to plug in your throttle to LocoNet initially to select the locomotive before you ...
