Device Overview

Front View: Features a power socket for connecting the power supply and an input/output connector for various signals. A Power LED indicates the device's operational status.

Back View: Includes a USB port for connection to a computer, a mobile antenna connector, and a reset button. It also displays Mobile network type LEDs and Mobile signal strength indication LEDs.

Hardware Installation

1. Unscrew the two back panel hex bolts and remove the back panel.
2. Insert your SIM card into the SIM socket.
3. Attach the panel and tighten the hex bolts.
4. Attach the mobile antenna (maximum torque 0.4 N·m / 3.5 lbf·in) and connect the USB cable.

Input/Output Connector Pinout

The input/output connector offers configurable inputs and relay contacts:

• DI1 and DI2: DRY/WET configurable inputs. WET: 0-1.9 V is "0", 1.9-3.8 V is "1". DRY: "0" when shorted to GND, "1" otherwise.
• NC*, C*, NO*: Normally Closed, Common, and Normally Open contacts for internal Relays 1 and 2. Relay 1 (Non-latching) ratings: 0.5 A at 60 VDC/70 VAC, 1 A at 30 VDC/VAC. Relay 2 (Latching) ratings: 0.8 A at 70 VDC, 0.9 A at 70 VAC, 2 A at 30 VDC/VAC.
• A: ADC input. Analog voltage range 0-30 V. Can be configured for 4-20mA sensor protocol (0-30 mA current measurement).
• I and : Isolated input contacts. 0-7.3 V is "0", 7.3-71 V is "1".
• +: Power output (+9 ... +30 VDC) connected to the gateway's power supply input. Useful for powering external sensors.
• 3.8: 3.8V power output for 1-Wire sensors.
• 1W: 1-Wire protocol input/output.
• : GND contact.

Power Socket Pinout

The power socket accepts a positive power input (+9 ... +30 VDC) via the red wire and a ground connection via the black wire. The white wire is for I/O.

Device Configuration

1. Connect the device to your computer using the USB cable and power it on. Allow up to 30 seconds for boot-up.
2. Your computer's OS should detect the USB device and install the driver.
3. Open a web browser and navigate to http://192.168.2.1 to access the gateway's Web interface (WebUI).
4. Enter the login credentials (default: admin/admin01) when prompted.
5. After logging in, observe the Signal Strength indication in the Mobile widget. Adjust antennas or device location to optimize cellular performance.
