VT10 / 1-Wire board

Physical description

When "VT10" is installed inside of monitoring unit, "VT10" looks like this:

1a. RJ9 jack for connecting 1-Wire sensors.

1b. Green LED. If the green light is "ON", then the 1-Wire board is on. There's an element inside monitoring unit's interface that can be switched "ON" and "OFF", which activates 1-Wire bus.


Monitoring units have the option of installing "VT10 / 1-Wire board" (expansion board). The board is mounted and connected inside the monitoring unit. 1-Wire technology is based on a serial communication protocol that uses one data line and a reference ground between the master (for example, the VT335 / Monitoring Unit) and one wire slave.

Carefully unscrew screws holding the cover and open it.


Break 2 steel bridges in the 1-Wire hole of the appliance case (e.g. VT335 top metal)cover. Using forceps (cutter) with thin nozzles cut the thin bridges in the hole. Make sure that no burrs are left.


Set up the 1-Wire board on 2 steel spacing sleeves inside the appliance case (e.g. VT335 top metal cover), attach the board with two M3 screws from supply to the sleeves.
