Wireless Diversity Receiver
Rio Rancho, NM – USA
SOFTWARE
UDRpanel software does not detect any connected receivers.
• Be sure receivers are powered on and properly connected. Select default scan limits and check COM port
settings in Options window. Check each receiver to make sure all receivers have unique LecNet
address settings.
UDRpanel detects some receivers but not others.
• Select default scan limits in Options window. Check each receiver to make sure all receivers have unique
LecNet address settings.
A pane in the main window appears “gray” and unresponsive.
• Communication with receiver was temporarily lost. Double-click the pane to attempt a reconnect. If reconnect
fails, check that receiver is powered on and connected. If you have exchanged receivers, rescan to
detect the new receiver(s).
Spectrum analyzer leaves “gaps” in coverage, even after repeated sweeps.
• Receiver has been programmed at the factory or dealer to have fewer than 256 channels.
Walk test recorder fails to play back audio.
• First, make sure your PC can play sounds. You should see a speaker icon in the system tray. If there is no
speaker icon, your PC’s sound system is not active and the audio capability will not work. When windows
starts, it normally plays a musical wave file. If you can hear it, the playback part of your windows sound
system is working. Confirm with headphones that audio is arriving at the receiver’s headphone jack. Connect
an audio cable (pn: 21675) from the receiver’s headphone jack to the PC sound card’s line or mic input, and
make sure that the receiver headphone volume is not turned all the way down. Double-click the speaker icon in
the windows system tray to access the Volume Control dialog. Select “Properties” from the Options menu,
choose the Recording controls and click OK. Be sure mic and line inputs are selected with moderate volume
settings and leave the Recording Control dialog displayed. Now switch to the UDRpanel receiver setup window
and start a walk test recording. Switch back to the Recording Control dialog and check the meters. Audio from
the wireless receiver should move the meters. Adjust the volume controls for a good meter indication. Return to
the UDRpanel receiver setup window, stop the recording, seek to the beginning and play.
I got all the panes just the way I wanted them, and now they’re back to their original positions and the receiver names
are back to the defaults.
• When you’re happy with a configuration, you must save it to a disk file. The next time you start UDRpanel,
ask to open a previously saved configuration instead of scanning.
I asked for a demonstration and now I want to leave demonstration mode and use the software on real receivers.
• The only way to do this is to exit the program and run it again.
When I tune the receiver from the setup dialog, it takes a second or so for some of the controls to update.
• The controls in the windows dialog can work much more quickly than the real receiver, so the program intro
duces a delay deliberately. When no retuning command has been issued for a half second, the actual tuning
command is sent over the LecNet so the receiver can “catch up”.
Sometimes when I exit UDRpanel, not all of my receivers are reset from “remote mode”.
• If you are using a mix of UDR200B and 200C receivers, occasionally minor timing conflicts can arise. The
erroneous remote mode can be cleared by running UDRpanel again or cycling the power on the affected
receiver(s).
The transmitter battery status is slow to appear and sometimes vanishes for no apparent reason.
• Transmitter battery status can only be reliably indicated if the signal strength has remained moderately strong
for at least 30 seconds. The software is trying to keep from displaying unreliable information.
