ATR833 / P/N 833-(1xx)-(1xx)
Operation and Installation
2.10 Remote Control Panel
In Tandem-aircrafts it is possible to control the ATR833 by a second
control panel (ATR600RT Remote Control Unit), which is connected to
the RS232 interface of the ATR833. This second control panel enables
to set frequencies and adjust Volume, Squelch, VOX and other basic
settings (see 2.4).
In case of an error in the transmission between ATR833 and its remote
unit, following error messages may appear in the second line besides
„VOLxx“:
1e = Time-out-transmission error
2e = erroneous transmission (e.g. checksum error)
3e = unknown command
The error message disappears as soon as a correct command is
received or the frequency is changed.
A malfunction of the remote unit does not impact the reliable operation of
the ATR833.
If the channel spacing (see 2.8.3.2) is changed at the main
device, the remote unit needs to be re-started in order to
consider this change.
