This menu enables setting the various CAN-Bus parameters. Before being able to
use the CAN bus, it is necessary to activate this function by pressing

CAN2.0A or as extended frames according to CAN2.0B. Correspondingly it is possi

enables alteration of the so-called
Bit Timing Register
for different baud
rates and sample points. It is possible to directly fill it with a 4 digit HEX value in the
range between 0 to 7fff (according to the Siemens Processor Manual S. 23-10 – Or

It is possible to alternatively alter each of the registers parameters separately; in ad

answered with the corresponding address.
NOTICE
Unexpected antenna resets
In case of transmission errors on the CAN bus, the antenna performs a reset. Also
the case that no device is connected when the CAN bus is activated can be
interpreted as a transmission error.
If the CAN bus is not used: deactivate the CAN bus.
