The objects are activated by entering an address other than 0 in the CAN menu (see
section 9.2.3.1 on page 34).
10.3.2.1 Reception Box Transponder Programming (Vehicle Controller –>
Transponder Antenna)
Length: 4 Byte
Used to program a new transponder code. To program a transponder:
There must be a transponder in the reading area.
A new transponder code is sent via the receive box shown above. The following
applies to this code:
–
The received code is different from the read code of the transponder under
the antenna.
–
The received code is different from a previously received code. The antenna
temporarily stores the last code received via the box. Only when a new code
is received is the programming process started.
After an antenna reset, the code 0000 is in the memory of the antenna. If the code
0000 is to be programmed, it is recommended to send another code and then send
the 0000 again.
If these conditions are met, the antenna starts the programming process. This
takes approx. 50 ms.
Via Status 1 (see section 10.3.2.3 below) it can be checked whether the
transponder sends the new code.
As soon as the new code is received via Status 1, the programming process is
finished.
10.3.2.2 Transmission Box 1 PosiPulse (Transponder Antenna –> Vehicle Con
-
troller)
Length: 0 Byte
No data, signals a Posipulse.
With the help of this telegram, a PLC, for example, can detect a PosiPulse via the
CAN bus without having to connect the corresponding output of the POWER con
-
nector.
