Function and purpose
Increases the number of analog sensors connected to any Vutlan monitoring unit. Each unit connected adds 8 analog sensors. Connects on CAN port and allows further CAN daisy chain connection. Sensors connected to the extension unit appear in the system automatically.
...
ERROR continuously lit, RUN flickers - the expansion module has no connection with the master module
ERROR is continuously lit, RUN is extinguished - the expansion module has communication with the master module, but is not included in the monitoring system (not configured)
ERROR is extinguished, RUN is continuously lit - the expansion module is included in the monitoring system

Mounting: Wall mount
There are x4 M3 thread holes at the bottom of the case. You can mount ‘VT123 / Wall brackets’ to these holes and then use them to mount onto the wall or surface. ‘VT123 / Wall brackets’ are ordered separately.
...
Use M3 screws to fix VT408 on the VT125t trays.

Installation
Connect the CAN input of the unit by RJ11/RJ12 cable supplied to the CAN input of the previous CAN unit or monitoring system. The red LED lights up. Match the TR bus terminators on the attached CAN units. CAN bus terminators TR (position 2 in VT450) should be in the ON state only at the end CAN units port and in Off states (1,2) for all intermediate units. One CAN bus can have not more than 8 CAN units, sensors, and/or another CAN device.
Normally 12V 0.5A external power supply is connected to the jack labeled PWR (point 2 in the general scheme). But if the only VT408 unit is connected and the length of the cable from the monitoring unit to the VT408 does not exceed 10m allowed the extension unit operation without any external power supply. In all other cases, the use of an external power supply is desirable.
