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 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.

Connection

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.

Installation and connecting of VT10 1-Wire board

To install and to connect extension units: switch off appliance, unplug from the outlet or disconnect the power connector.

1		Carefully unscrew screws holding the cover and open it. Depending on the monitoring system, it may have: 1-Wire, Antenna, GSM or Dry Contacts or any other additional modules installed inside. Carefully open the box by unplugging, if necessary, any cables that connect from top cover to bottom cover.
2		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.
3		Set up 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.
4		Connect "16 wire IDC16 flat cable" supplied with "1-Wire extension" board to the connector on the 1-Wire board and on main board (e.g. VT335 board).
6		Close and fasten the cover. Carefully place top cover back so that all cover wings fit in and all cutoffpoints match the panel holes.
