C(A)N Parameters
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
.
ATTENTION!
In case the CAN bus is not connected, it is essential to deacti-
vate this function, as transmission errors will lead to antenna
reset while the CAN bus it activated!

Entering
enables generation of telegrams either as standard frames according to
CAN2.0A or as extended frames according to CAN2.0B. Correspondingly it is possi-
ble to either set the
dentifier (CAN address) as 11 bit value (0-2047) or as 29 bit val-
ue (0-536870911).
The identifier, that is adjustable via
, refers to transmitted frames for Message Object
1 (Table 11 on page 23) and to received frames for Message Object 4 for the reference
transponder (Table 14 on page 25), respectively. The Identifier adjustable via
refers
to Message Object 2 (Table 12 on page 24),
, accordingly, refers to Message Ob-
jects 3 (Table 13 on page 24). Entering 0 deactivates the corresponding Message Ob-
ject.
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 — Ordering No.
B158-H6651-G1-X-7600).
It is possible to alternatively alter each of the registers parameters separately; in addi-
tion, without knowledge of the exact meaning of the single timing parameters, one out
of five possible baud rates can be selected
