4.2.3.2.6
CAN Message Object 4 (Reception Object)
It is possible to send commands to the antenna. For this it is necessary to send a Mes-
sage Object with the same address as Message Object 1 and a length of 6 bytes.
4.2.3.3
Positioning Pulse
The digital positioning output indicates the antenna center crossing in direction of trav-
el. Its duration can be set within a millisecond pattern. Furthermore it is possible to limit
it to one pulse per crossing.
It is possible to ’freeze’ the content of the serial telegrams at the time of the positioning
pulse for an adjustable number of telegrams (refer to section 5.3.2.2 „(S)erial Output“
on page 35 and 5.3.2.5 „C(A)N-Parameters“ on page 39).
4.2.3.4
Analysis Interface
This interface (pin „R“ of the connection socket, see Table 1 on page 17) enables re-
cording important system data independently of the serial data traffic. The interface
parameters are:
57600 Baud, 8 Data bit, no parity
The following values are output as ASCII characters, separated by commas. Each line
is terminated with CR LF.
