1. "CAN" - digital connector RJ12 for the connection of CAN sensors and CAN extensions on a CAN bus, with auto-sensing.

2. LEDs:

  • "ACT" - indicates appliance status:    

         - operating mode of the device: switches at a frequency of 2 times per second;

         - successful completion of the software update process: switches at a frequency of 4 times per second;

  • "E1" - indicates 12V E1 relay status;

  • "E2" - indicates 12V E2 relay status;

  • "ERROR" - indicates error and traffic:

          - operating mode of the device: the norm is extinguished, not the norm - a constant glow;

          - режим обновления ПО: переключается с частотой 2 раза в секунду;

• Blinking "ACT" ............ • Blinking "E1" ............ • Blinking "E2"............ • Blinking "ERROR" ..........

3. "LAN" - Ethernet 10/100 Base-T port, provides Ethernet connection.

• LEDs - "yellow" (status) and "green" (traffic) show the network traffic. The status LED: flashes green when the system starts up, and shows the connection state (constant green light - the connection is established, blinking green - the connection attempt).

4. "HS USB" - type miniAB USB-port 2.0, required to connect a USB camera or to restore an appliance.

5. "RESTART" or "RESET" - restarts the appliance.

6. LEDs: "CAN" - indicates CAN bus status:

  • "CAN" blinks slowly - nothing is connected

  • "CAN" blinks fast - configuration is in process

  • "CAN" glows constantly - connected to CAN devices

7. "1-WIRE" - can be used with VT10 / 1-Wire extension board". Allows connecting 1-Wire reader or 1-Wire temperature sensors in serial line. Has "1-WIRE" status led.

8. "SD" - SD, MicroSD card connector with ejector, needed to store data.

9. This is a slot for "VT760 / Internal LTE modem". The modem is purchased separately!

9a."Main antenna" - Connector, used when the LTE modem is installed inside of the appliance to connect LTE main antenna. (The main antenna is supplied together with the modem).

9b.  "Auxiliary antenna" - Connector, used when the modem is installed inside of the appliance to connect LTE auxiliary antenna. The additional antenna helps to strengthen the signal level. (Auxiliary LTE antenna and antenna output are ordered separately from the modem).

10. LED: "MODEM STATUS" - indicates SIM card status. Blinking = working. (VT760 / Internal LTE modem is ordered separately)

10b. "SIM card" - SIM card slot with an injector.

11. "A1..A8" - 8 RJ12 analog sensor inputs with auto-sensing.

12. "DC 12V 2A" - DC power input.

13. "Dip switch" Normal ↑ Off - the system should be always switched to this mode.

Recovery ↓ On - use this option only in case you need to recover manufacturing settings.

14. "" - External chassis grounding, M4 thread.

15. "TEMPERATURE SENSOR" - accuracy +/- 1 °C.

16. "DRY CONTACTS 1...4" - Dry contacts terminal (type IN)

17. "OUTPUT 12V 0.25A" - 12V 0.25A output electronic relay terminal
