34.7.2 Defined Baud rates
The Baud rate must be selected according to the length of the cable. See
"Maximum cable length".
The following Baud rates can be set via rotary switch:
Switch position Baud rate
0 Delivery condition, not allowed during operation, see infor-
mation.
1 125 kbit/s
2 250 kbit/s
3 500 kbit/s
4 800 kbit/s
5 1 Mbit/s
6 - F not allowed.
The firmware adopts the adjusted Baud rate once during start-up of the
CECX-B-CO. Changing the Baud rate during operation
is not possible.
Information
The CECX-B-CO is delivered with the Baud-switch position 0. It is manda-
tory that it is set accordingly. If the Baud-switch position is invalid, the
communication with the CECX-B-CO is disabled (Status LED illuminates
red).
To increase the robustness of the CAN-network, the Baud rate should be
selected accordingly lower. The set Baud rate must be set using the con-
figuration tool
Match the Baude rate, otherwise an error is issued.
