KHF 1050 SYSTEM INSTALLATION MANUAL
An external controller turns on the KRX 1053
Receiver/Exciter by asserting the POWER ON/OFF CONTROL
discrete input. In an installation in which LRU power
is to be controlled by a radio master switch or relay,
this input may be permanently strapped to ground.
This input is continuously read.
When the TUNING MODE discrete input is not assorted,
the CONTROLLER SELECT discrete determines which HF
controller input is active.
NOTE:Asserted = GND, Not Asserted = OPEN
The KRX 1053 Reciever/Exciter accepts tuning and
control data from the HF CONTROLLER INPUT #1 when the
CONTROLLER SELECT and TUNING MODE discrete inputs are
not asserted.
The KRX 1053 Receiver/Exciter accepts tuning and
control data from the HF CONTROLLER INPUT #2 when the
CONTROLLER SELECT discrete input is asserted and the
TUNING MODE discrete input is not asserted.
This input is continuously read.
When the BURST/CONTINUOUS TUNING MODE discrete input is
not asserted, the KRX 1053 Receiver/Exciter operates
with continuous tuning and mode control data and the
CONTROLLER SELECT discrete input determines the active
controller input.
When the BURST/CONTINUOUS TUNING MODE discrete input is
asserted, the KRX 1053 Receiver/Exciter operates by
receiving bursts of tuning data.
