Part No. 001-4008-101/102

Range

This field designates radio frequency range.

Channel

This field specifies whether the unit is quarter-, full-, or half-channel (6.25, 12.5, or 25 kHz).

Transceiver Type

This field configures the transmitting and receiving characteristics of the unit according to 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

Carrier Sense

Denotes the RSSI level when the unit senses a carrier. Carrier Sense is used for data recovery, in the interpre-

tation of diagnostics, and to turn on the front panel CS LED. The threshold may be raised to prevent false

Carrier Sense operation in the presence of noise, inter-modulation, or other sources of interference (i.e. for

ambient noise at -100 dBm, set the Carrier Sense for -95 dBm).

Tx Timeout

Tx Timeout is used to set maximum period of time the unit will allow in a transmission. The range is 0 to 120

seconds in 1 second intervals (0 being disabled). Tx Timeout is used to protect both the unit and the net-

work in case a transmitter becomes stuck on the air. For Integra-TRs equipped with the cooling option for

extended transmit applications, the Tx Timeout must be disabled.

Rx Frequency

Rx Frequency designates channel pair transmit frequency.

Tx Frequency

Tx Frequency designates channel pair receive frequency

Power

This field designates the channel pair Power Output Adjust value. The default value is 255 (5 watts). This

value should be left at the default value unless lower power is required to meet regulatory requirements or to

increase the allowable transmit duty cycle.

NOTE: Power does not vary linearly with this parameter so some experimentation may be required to

determine the correct power setting.
