7.1.2 CAN bus cable
Galvanically separated
Maximal CAN bus length 200m Speed 250kBd
Nominal impedance 120Ω
Cable type twisted pair (shielded)
Following dynamic cable parameters are important especially for maximal 200 meters CAN bus length and 32
iS-COM units connected:
Nominal Velocity of Propagation min. 75% (max. 4,4 ns/m)
Recommended data cables: BELDEN (
For shorter distances (up to 50 m): 3105A Paired - EIA Industrial RS-485 PLTC/CM (1x2 conductors)
For longer distances: 3106A Paired - EIA Industrial RS-485 PLTC/CM (1x2+1 conductors)
7.1.3 RS232 cable
It is recommended to use standard Null-modem cable for local connection between controller and PC, although
the three wires (TxD, RxD, GND) RS 232 connection is enough for direct controller to PC communication:
