Move S1 to position ON to activate the CAN terminating resistor.

The mounting hole at the bottom right corner is electrically connected to the ground plane of the USBoard. Please insulate this mounting point if necessary in your installation.

The USBoard can be mounted both horizontally and on walls. Please note that when mounted upside down the relays might malfunction. The data output is not affected by the mounting orientation.

Tip

More information about these connectors can be found at Connectors.

Connector X1 – WE MPC4, 6-pin

Pin Description
1 Power supply input
2 CAN High
3 CAN High
4 Ground (for both power supply and RS-232)
5 CAN Low
6 CAN Low

Pins 2 and 3 are bridged, as well as pins 5 and 6. This allows two CAN cables (CAN-in and CAN-out) to be connected easily.

Pin Description
1-4 Sensor power supply 0 V
5 Sensor 1
6 Sensor 3
7 Sensor 5
8 Sensor 7
9-12 Sensor power supply +8 V
13 Sensor 2
14 Sensor 4
15 Sensor 6
16 Sensor 8

Connector X3 – WE MPC4, 16-pin

Pin Description
1 Sensor 9
2 Sensor 11
