Further information concerning number:
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 protocol
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“ (only valid for systems that include a reference
transponder). Please note that, while the reference transponder is activated, the
runway transponders cannot be processed unambiguously, i.e. they are either
oppressed or their position is inaccurate.
3.
The successful deactivation of the reference transponder is signaled by the
deletion of the „0x0100“ bit from the system status.
4.2.4.1.3
System Monitor
In monitor mode the system is configurable via a menu. Please refer to section 5.2
4.2.4.2
Positioning Pulse
The digital positioning output indicates the crossing of the center line of the antenna
in direction of travel (X- direction). Its duration is adjustable within a millisecond pat-
tern. In addition it can be limited to one pulse per crossing.
4.2.4.3
CAN
4.2.4.3.1
Description
Either Basic- or Full-CAN mode is configurable. The system monitor is used for setting
the CAN parameters (also refer to section 5.2.2.5 on page 35). The internal CAN mod-
ule is based on the CAN specifications V2.0 part B. It is possible to transmit either
standard or extended frames (adjustable). The system monitor is used for setting the
bit timing as well as the identifier.
It is possible to output four different CAN Message Objects and receive one. It is con-
figurable whether telegrams are output permanently according to the set update rate
or only while a transponder is within the field. In addition, remote operation is select-
able.
The objects are activated in the CAN menu by input of an address different from 0.
