VT10 / 1-Wire board

Physical description

It is possible to connect up to two readers to one Vutlan monitoring system. Please use a splitter to do this. In such a case both readers are seen by the system as one reader. This is useful when one reader is used for entrance and one reader for the exit of the same door.

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.

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 the 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 the 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 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.
4		Connect "16 wire IDC16 flat cable" supplied with a "1-Wire extension" board to the connector on the 1-Wire board and on the mainboard (e.g. VT335 board). Make sure is installed in 2-3 position
6		Close and fasten the cover. Carefully place top cover back so that all cover wings fit in and all cutoff points match the panel holes.
