the layout and check Duplex operation for adequate signal coverage.
Depending on the layout size, geometry and surrounding materials it is often
possible to move the UR92(s) to better cover dead spots. Experimenting with
UR92 location will usually help you locate a position that is best for your lay-
out. Note that DT402D orientation and body position of you and your opera-
tors may also affect the UR92’s range and reception.
On very large layouts or layouts with problem areas, it is possible to add more
than one UR92. Adding extra units will automatically provide space-diversity
coverage and reliability. Adding multiple UR92s is covered in the Advanced
Installation and Customization section of these instructions.
If duplex range is poor, it may be due to interference from a Wireless LAN or
similar device operating continuously on the same channel. The next section
outlines several ways to avoid interference and congestion from other devices.
20.3 Resetting UR92 To 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.
1. Disconnect the UR92(s) from the LocoNet. If you have more than one
UR92 in your layout, you must disconnect all of them to do a full factory
reset on each unit as follows.
2 Disconnect any throttle that is plugged into the UR92.
3. Leave the PS14 power supply connected to the UR92 and to the wall outlet.
4. Press and hold the button (next to the power supply jack) for two seconds or
until both the red and green LEDs begin to blink. Release the button.
5. When the lights stop blinking, unplug the power supply.
6. Reconnect the PS14 DC power supply to the UR92. The green and red
LEDs will blink and then the red LED will stay on.
7. Connect the UR92 to your working LocoNet system using one of the RJ12
jacks at the rear of the UR92. The red LED will go off and the GREEN
RADIO
LED will blink at a 2-second interval to indicate that it is set up for
duplex radio operation and is working.
8. The UR92 is now set to the factory default Group Name of
Dtxnnnn
(where “
nnnn
” is the unit serial number) and Channel 11.
