Connecting analog sensors

Connect the analog sensor by a supplied RJ-11 (6P4C) cable to any analog port "A1 .. A8" or "Sensor" port. The determination of the sensor type and connection will occur automatically.

6P4C RJ11 cable wiring/pinouts

1- Orange, 2- White Blue, 3- Blue, 4 - White Orange

Colors are true for this telephone cable. Both ends match the colors and pinouts (identical).

Please refer to the RJ connectors comparison table:

Daisy chain connection

Some of the analog sensors can be connected to a daisy chain. Please refer to the article "Chain Connection of analog sensors".

Maximum cable length test

Extending the number of analog sensors

Using CAN extension "VT408 / Sensor extension unit" it is possible to increase the number of analog sensors connected to the monitoring unit up to 80 sensors.

Chain connection of analog sensors

This procedure applies to the following sensors, which are supported by the appliance and are connected to the analog ports:

VT530 and VT560 are the only analog sensors that allow non-addressable chain connection.  All the sensors in one chain are seen by the system as one sensor.  One chain can have up to 10 sensors. Example of such connection:
