Wireless Diversity Receiver

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”.

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.
