Chapter 5 – Components and Operation
3 different CAN message objects can be output and 1 can be sent. In addition it is to
be set whether telegrams are to be output permanently at the set update rate or only
as long as a transponder is within range. Remote operation is also possible. Objects
are activated within the CAN menu, through the input of an address unequal 0 (refer
to section 6.3.2.5.1 on page 40).
5.2.2.3.2 CAN Message Object 1 (Send-Object)
5.2.2.3.3 CAN Message Object 2 (Send-Object)
5.2.2.3.4 CAN Message Object 3 (Send-Object)
5.2.2.3.5 CAN Message Object 4 (Reception-Object, Transponder Program
-
ming)
Via the reception Message Object 4 commands can be sent to the antenna. It has
the same ID as the send object Message Object 1 and a length of 8 byte.
