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. |
