HTerminators must only be fitted at both ends of the network, not at intermediate nodes.
HThe 0V connection of all of the nodes on the network must be tied together through the CAN cabling. This ensures that the CAN signal levels transmitted by NextMove PCI or CAN peripheral devices are within the common mode range of the receiver circuitry of other nodes on the network.
