DeviceNet Connections
The DeviceNet interface connections are made on a 5 pin removable screw terminal on the front
of the Gateway. The connector is numbered from left to right as follows:
1. V- DeviceNet input power return
2. Can Low
3. Shield
4. Can
High
5. V+ DeviceNet input power (15 to 24 VDC from host)
DeviceNet Power
15 to 24VDC power must be supplied to the DeviceNet connector for the DeviceNet communications to
operate. The power must be connected to the 5 pin screw terminal. In normal operation this is a separate
supply from the CANBus transducer supply.
DeviceNet Termination
For proper operation the DeviceNet cable must be terminated with a 120 ohm resistor at each end of the
cable. The XG555 provides DeviceNet interface termination on the DeviceNet interface board. An external
termination resistor should not be added at the XG555 end of the DeviceNet network. If the transducer
bridge is not the last DeviceNet node on the cable and termination is provided elsewhere, you will have to
disable the termination on the transducer bridge. To disable the on-board termination, remove jumpers LK4
and LK5 from the DeviceNet interface board.
