5.2.6.1.2 List of commands
One command telegram always consists of four bytes, including the actual com -
mand and the parameters. When using the procedure ‘transparent’ (also refer to Ap -
pendix, section 10.7 on page 50) it is, in addition, necessary to transfer one start
character and a check sum (XOR operation of all bytes including the start character).
5 commands are defined:
Further information regarding command no. ...
1. The monitor mode should not be used during normal operation (e. g. from an
PLC), as the following output is not according to a transparent or 3964R proto
-
col but only suitable for display on a VT52-terminal and used for the alteration
of parameters.
2. An activated reference transponder is described by setting the corresponding
bit in the system status “0x0100“.
Please note that while the reference transponder is activated, the runway tran
-
sponders cannot be processed unambiguously, i.e. they are either oppressed or
their position is inaccurate.
3. The successful deactivation of the reference transponder is described by delet -
ing the “0x0100“ bit from the system status.
