Functional description & components
1. "LED: ACTIVITY" - green LED indicates appliance status
"LED: ERROR» - red LED indicates system error and traffic.
2. "Analog sensors: A1..A6" - x6 RJ12 analog sensor inputs with auto-sensing. Read instructions at "Analog sensors connection", "Sensor configuration".
3. "USB" - type miniAB USB-port 2.0, required to connect a USB camera, USB flash, USB hub or to restore an appliance using USB flash.
4. "CAN" - digital connector RJ12 for the connection of CAN sensors and CAN extensions on a CAN bus, with auto-sensing. Read instructions at "CAN devices connection", "Setting up CAN".
- "CAN Status" - LED for digital bus sensors:
- The LED blinks slowly - nothing is connected
- The LED blinks fast - configuration is in process
- The LED glows constantly - connected to CAN devices
5. "LAN port" - Ethernet 10/100 Base-T port, provides an Ethernet connection.
- "LAN Link" - orange LED for Ethernet port. It shows network traffic.
- "LAN Activity" - green LED for Ethernet port. It shows network traffic. Flashes green when the system starts up. Shows the connection state (constant green light - the connection is established, blinking green - the connection attempt).
6. "DRY CONTACT INPUTS 1...4" - Digital inputs. Read instructions at "Connecting dry contacts", "Dry contacts settings".
7. "TEMPERATURE SENSOR" - accuracy +/- 1 °C.
8. "MODE" - a DIP switch for changing system modes.
- Normal mode 🠀: Normal operating state. The system should be always switched to this.
- Recovery 🠂: Turns a recovery mode On. Use this option only in case you need to recover manufacturing settings. Read instructions at "Factory settings recovery".
9. "RESTART" - button restarts the appliance. Press the button for several seconds.
10. "OUTPUT 12V 0.25A" - 12V 0.25A output electronic relay terminal. Read instructions at "Connecting 12V devices to 12V outputs".
11. "ISOLATED DRY CONTACTS OUTPUTS 1...4" - Digital outputs 24VDC / 15mA (type OUT). Read instructions at "Connecting dry contacts", "Dry contacts settings".
12. "RS-485 MODBUS RTU" - port for connecting Modbus RTU / RS-485 sensors and devices. Read instructions at "Connecting Modbus RTU sensors to VT336 & VT336PoE", "Configuring Modbus devices".
- "RS-485 Status" - LED for displaying Modbus RTU port status.
13. "DC 12V 1A" - DC power input. Instructions are in the section below.
14. "Modem" - "VT770 / LTE, GPS modem" is ordered separately. Read instructions at "Connecting VT770 / LTE modem with GNSS", "Network: LAN, GSM, LTE, RADIUS, DNS, SSL, VPN".
- "Modem status" - LED displays modems status.
- "SIM card slot" - Open the top cover to insert a SIM card.
- "GSM, LTE main antenna" - Connect GSM or LTE main antenna.
- "LTE auxiliary antenna" - Connect LTE auxiliary antenna (Auxiliary LTE antenna and antenna output are ordered separately from the modem). It helps to establish a stronger and more stable signal.
- "GPS active antenna" - GPS antenna and antenna output are ordered separately from the modem. Allows to set the time using GPS and shows the location of the device on the map.

Powering the device
Power supply with grounding.
Power supply without grounding.
Powering the device using VT-RM-9-12 / Mosfet Redundancy module
VT-RM-9-12 decouples the outputs of the power supplies (9-12VDC, Max. 5A). Automatically supplies load current (Smooth Switchover) from the system input supply with the higher voltage.

Mounting the device on a DIN rail
|1||Insert the DIN rail holder as shown in the picture|
|2||Press the module onto the DIN rail, it should snap.|
To dismantle the unit from the DIN rail:
- Use a flat screwdriver and insert it into the DIN rail holder.
- Pull the handle of the screwdriver to start pulling the DIN rail holder.
- Now You can pull the enclosure from the DIN rail.
Mounting enclosure guards
- Use pliers or a cutter to cut necessary plastic petals.
- Use a screwdriver to make necessary holes in the plastic guards.
|2||Simply slide it inside the empty spaces until it clicks.|
|3||Use a screwdriver to pull it out.|
The system uses terminal blocks for several interfaces:
They share the same characteristics.
