The connection of pin 1 and pin 3 is not required for
the CAN bus; neither is the bridge on the side of X7:
X7/5 - X7/9.
There is electrical signal separation between the
individual COMPAX.
Terminator
The terminator with 120W resistance (between
CAN-H and CAN-L) at the start and end of the serial cable
(e.g. control and last COMPAX) is recommended.
4.2 Device Settings
CAN-Bus settings are made using COMPAX parameters;
these may be set from the front panel (see next page).
4.2.1 Node ID (Device address)
Settable on every COMPAX using parameter P194; value
range: 1...127.
99: Standard setting;
4.2.2 Baud rate
Up to 1M baud possible.
The baud rate is set with parameter P195 (unit: Bit/s). The
following baud rates are possible:
20 kbit/s
50 kbit/s
100 kbit/s
125 kbit/s
250 kbit/s
500 kbit/s
800 kbit/s
1000 kbit/s
