Wireless Diversity Receiver

LecNet

COMPUTER INTERFACE

MICROPROCESSOR CONTROL

An internal microprocessor controls the frequency

settings and display, and provides a user friendly

interface for setup and operation. 256 frequencies

are available in 100KHz steps. The 25.6 MHz

bandwidth covers more than four UHF television

channels to allow maximum flexibility in frequency

coordination for congested RF environments and

in travelling venues.

THE LecNet

INTERFACE

All setup functions and almost all operational

functions are available from the UDR200B front

panel without the use of a PC. Via a PC, several

other features are added to simplify setup and

enhance monitoring during operation. LecNet

software is

supplied with the UDR200B.

The first display that appears when the UDR200B software is

loaded is a composite summary of up to 8 receivers, showing

basic RF and audio levels and frequency settings. Each of the

8 display screens includes a button to switch to the complete

control panel for that specific receiver.

For multi-channel systems, each UDR200B

receiver is assigned a unique serial address

from the front panel of the receiver. When

the LecNet

Master Pro software is then

launched, a role call is initially taken to

identify all devices that are connected.

AUTO SEARCH FUNCTION

The UDR200B provides the installer with a convenient method

of conducting a “site survey” when setting up for a new venue

or installation. The Auto Search function scans either the

entire tuning range of the receiver, or a selected frequency

group, and locates RF signals in the vicinity. The results are

graphically displayed in the lower section of the screen. The

screen markers are a peak holding type to record activity over

any chosen time period. The Auto Search procedure is espe-

cially valuable in travelling or rental venues that set up and tear

down frequently.

When the “Receiver Setup” button is clicked, a detailed display

appears with a wide variety of information dynamically dis-

played. RF and audio levels, Opti-Blend

panning activity,

frequency, pilot tone status, user and group names for each

receiver, and all information provided by the front panel LED

character strip is clearly displayed. Frequencies can be

changed to any frequency within the range of the receiver, or

to only those included in a previously selected, compatible

grouping.

The individual receiver control panel includes three sections to

display current settings, provide a workspace for new fre-

quency groups and a spectrum analyzer section for site sur-

veys.
