Tune Range
For UHF Range 0 25 kHz units only: Tune Range allows setting of the Integra-TR to the low or high end of the frequency
(242-4048-030: 406.1-422 MHz Low Rx, 242-4048-031: 414-430 MHz High Rx).
Transceiver Type
These radio buttons configure the transmitting and receiving characteristics of the unit according to the type of network
application:

Tx Only - For use in a full-duplex application to disable receptions on the unit used as the transmitter. Tx Only
designation pre-loads the synthesizer and allows faster attack time to speed up transmission response.

Rx Only - For use in a full-duplex application to disable transmissions on the unit used as the receiver. Rx Only
designation prevents accidental transmissions.

Transceiver - For use in all other applications.
Disable Tx w/Carrier Present
The Disable Tx w/Carrier Present provides the following options to configure unit reaction to an RF carrier presence when a
transmission is to begin:

Disabled - Select this option to instruct the unit to allow a transmission when a carrier is present.

Enabled (Discard data) - Select this option to instruct the unit not to allow a transmission if a carrier is present. Any
user data the unit receives on the COM Port while a carrier is present, is ignored and discarded.

Enabled (Buffer data) - Select this option to instruct the unit not to allow a transmission if a carrier is present. Any
user data the unit receives on the COM Port while a carrier is present is buffered and sent when the carrier is no
longer present.
Carrier Sense
Denotes the RSSI level when the unit senses a carrier. Carrier Sense is used for data recovery, in the interpretation of
diagnostics, and to turn on the front panel CS LED. The threshold may be raised to prevent false Carrier Sense operation in
