If you connect to a standard RS232 interface of a PC (9-pole male submin D
connector), the used cable must look like this:
Additional RS232 connection available:
8.8.2 CAN Bus
The CAN interface is designed according to ISO 11898. It is a two-wire connection with
differential signals. ISO 11898 specifies a bus cable with two signal lines, CAN_H and
CAN_L. The lines have a rated impedance of 120 Ohm. The signal lines are connected
to a terminating resistor (120 Ohm) at both ends of the bus cable (see figure).
The total length of the bus cable must not exceed the specified lengths. The following
table indicates physical limitations valid for specific transmission rates:
Baud rate
Max. bus length
50 kBd 1000 m
125 kBd 500 m
250 kBd 250 m
500 kBd 100 m
1000 kBd 25 m
