Interfaces and Connector Assignments 6.3 24 V and CAN via InRailBus Power supply voltage and CAN can optionally be fed via InRailBus. Use the mounting-rail bus connector of the CBX-InRailBus for the connection via the InRailBus, see order information in the appendix (page 46). Take notice of the instructions for connecting power supply and CAN signals via InRailBus in the appendix! 6.4 DIAG The serial diagnosis interface DIAG does not fulfil a function and is only used for manufacturing purposes. 6.4.1 Assignment Note: The module may only be operated with USB nets with USB interfaces with versions 1.1 or 2.0! Operability can only be guaranteed for these USB interfaces.

Correctly Wiring Electrically Isolated CAN Networks 7 Correctly Wiring Electrically Isolated CAN Networks Generally all instructions applying for wiring regarding an electromagnetic compatible installation, wiring, cross sections of wires, material to be used, minimum distances, lightning protection, etc. have to be followed. The following general rules for the CAN wiring must be followed: 1 A suitable type of wire (wave impedance approx. 120 Ω ±10%) with an adequate wire cross section has to be used and the voltage loss in the wire has to be considered! 2 A CAN data wire requires two twisted wires and a wire to conduct the reference potential (CAN_GND)! For this the shield of the wire should be used! 3 The reference potential CAN_GND has to be connected to the earth potential (PE) at one point. Exactly one connection to earth has to be established! 4 A CAN net must not branch (exception: short stub lines) and has to be terminated by the wave impedance of the wire (generally 120 Ω ±10%) at both ends (between the signals CAN_L and CAN_H)! 5 Stub lines have to kept as short as possible (l < 0.3 m)! 6 The bit rate has to be adapted to the wire length. 7 CAN wires should not be laid directly next to disturbing sources. If this cannot be avoided, double shielded wires are preferable. 8 When using double shielded wires the external shield has to be connected to the earth potential (PE) at one point. There must be not more than one connection to earth.
