2.2 Input Ports Setup
The digital and analogue inputs are configured by the use of jumper settings depending on the type of
sensor and/or signal to be applied to the specific port.
- See Appendix-B for connection diagrams applications examples -
To access the configuration jumpers, remove the terminal covers by pressing down gently on the centre of
the covers and sliding them off, then unclip the top cover by lifting it while gently pushing the end plate
outwards.
The table below shows a general guide to the jumper configuration for various sensor/signal types. The
jumper settings are shown with the LeNETmobile in the same orientation as the other diagrams in this
manual.

Note: A digital port that is not used should be configured as dry contact and any analogue port that is not
used should be set to 0 – 5 VDC modes.
The following points should be considered before connecting the sensors with the LeNETmobile:
Some general instructions about the sensor installation are given below:
•
LeNETmobile should be powered OFF before connecting or disconnecting sensors.
•
For the sensors employing shielding wire, make sure that shield is connected to ground (GND)
port at LeNETmobile and is not connected at the sensor side.
