Termination
For proper operation, a 120-ohm terminator is required at the ends of the CAN and/or RS-485
bus. If multiple devices are on the bus, only the devices on the ends of the network bus need
termination resistors. Figure 8 shows an example of how to terminate the network. Termination
may be provided as part of the network cabling or 120-ohm termination plugs for the RJ-45
communications connector on the charger are available to order separately (SENS p/n 803707).
