4. Remote Control
Tandem-seat airplanes can be equipped with the KRT2RC Remote
Control Unit. The remote control unit is connected to RS232 serial
interface and enables selection of the most common settings like
frequency, volume, squelch, VOX, display contrast and brightness. In
addition the unit has an independent memory for favourites (frequency
and designator).
Transmission error messages are displayed in the error window in the
third line
R_Time = Time-out transmission error
R_ChkS = Checksum error
R_Cmd = Unknown command
R_Char = Data error
R_Freq = Wrong Frequency
The error message disappears when a valid command or a new
frequency has been input, latest however after 5 seconds.
Remote control unit errors do not interfere with the KRT2
transceiver operation.
Data transmissions between the transceiver KRT2 and the remote control
unit is checked once every minute. A “r” in the upper right corner is
displayed when there is no malfunction.
