Functions:

1. N - R - DIP switch for operation mode
   N / Normal Operation: The switch is toggled to the left ← and should always remain in this position.
   R / Appliance Restore: The switch is toggled to the right →. Used to load the clean system image from an SD card.

2. LTE Slot Modem - The LTE modem can be installed in this slot. This modem is ordered separately.

3. SD Card - MicroSD card slot with ejector. The card is needed for data storage or system restore.

4. LAN Port - Ethernet 10/100 Base-T port providing an Ethernet connection.
   Orange LED - orange LED for the Ethernet port, indicates network traffic.
   Green LED - green LED for the Ethernet port, shows network status. Flashes green during system startup. Indicates connection state (solid green = connected, blinking green = connection attempt).

5. USB - USB Type C required for USB camera recording, USB flash for system logs and system restore.

6. CAN - digital RJ12 6P4C connector for connecting CAN sensors/extensions/devices on a CAN bus. Modules can be cascaded.
   LED: CAN - green LED indicates the status of the CAN bus.
   The LED blinks slowly - no connection
   The LED blinks rapidly - configuration in progress
   The LED glows steadily - connected to CAN devices

7. Reset settings - resets settings to factory defaults. Hold the button for more than 5 seconds. The ERR LED begins blinking indicating restoration has started. Wait 20-60 seconds for the system to restart. The ACT LED starts blinking when the system is ready. The device is now accessible.

8. Analog Sensors: A1..A4 - 4 RJ12 6P4C analog sensor inputs with auto-detection.

9. Dry Contact Inputs 1...8 - Dry contact inputs (Type IN). Pitch 3.5 mm, 6-pin.

10. Restart - the button restarts the device. Hold the button for 2 seconds and then release. The system will restart.

11. Isolated Dry Contact Outputs

12. Modbus RTU Expansion Slot / VT485 Expansion Slot

13. Relay Outputs 12V DC 0.25A - 12V 0.25A (per output) terminal outputs (electronic relay). Pitch 3.81 mm, 3-pin.
    LEDs: E1, E2 - status indicators for two 12V 0.25A outputs on the front panel.
    The LED is ON (orange) - output is ON (initial state configurable).
    The LED is OFF (orange) - output is OFF (initial state configurable).

14. System LEDs
    LED-ACT - green LED indicates system status,
    - device operating mode: blinks at 2 Hz;
    - successful completion of software update: blinks at 4 Hz;
    LED: ALARM - can be programmed via interface for alarm indication.
    LED: ERROR - red LED indicates errors and data traffic.
    Operating mode: LED off when normal, solid on if error;
    Software update mode: blinks at 2 Hz;

15. DC 24-48V BACKUP POWER - 12V DC 2A alternative power supply. Terminal pitch 5.08 mm.

16. DC 12V BACKUP POWER - 12V DC 2A alternative power supply. Inner contact diameter 2 mm, outer contact diameter 6.3 mm.

17. DC 12V POWER - 12V DC 2A main power supply. Pitch 3.81 mm, 2-pin.
