TECHNICAL DATA
4.1 General
4.2 CAN cable
The recommended cables for installations are 4 wires twisted and a shielded cable with an
impedance of 120 Ohm. The network topology is a 2-wire bus line that is terminated at both ends by
resistors representing the characteristic impedance of the bus line. The typical CAN cable
impedance is 120 Ohm, and so for the termination resistors of ~120 Ohm must be used. For long
networks a higher resistor value must be used (150-300 Ohm).
