CAN bus addressing and termination

Version: 00
If a controller is replaced, e.g. during repairs, take care that the four
DIP switches correctly are reset on each of the three controllers.
In particular, wrongly set termination DIP switches can result in
faults during operation which are often hard to locate and occur only
intermittently.
If two controllers accidentally have the same address, or if one has
an inadmissible address, operation is not possible. In these cases
an error code is displayed at MBC-110.
4 DIP switches on each
