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 settings. In addition the unit has an independent
memory for favorites (frequency and identifier).
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 transmission between the transceiver KRT2 and the remote control
unit (KRT2-RC) is checked once every minute. A “r” in the upper right
corner is displayed when there is no malfunction.
The KRT2-RC can also operate the KRT2 in a fully stand-alone mode such
the KRT2 can be installed anywhere in the aircraft and be operated
remotely by the KRT2C. This feature will be useful in tandem aircraft, or
aircrafts with very little space behind the instrument panel.
