Power Supply

Use the appropriate cord for your geography. Any IEC320-C7 power cord with appropriate safety agency rating is acceptable for use, but do not use the IEC320-C7-PW cords that are squared on one side. The image below shows the power supply and power cords supplied with the system.

NGR-30 Power Supply

Note: The power supply included with the Gateway is 100-240 Vac, 50/60 Hz input, 12 Vdc, 2A output. A. No other power supply should be used beyond what has been provided with the kit.

To install the power supply follow these steps:

  • Attach the cord for your geography to the power supply. The power supply is external to the Gateway. It is a brick style.
  • Insert the power supply plug into the power socket on the top of the Gateway.
  • Plug in the cord to the wall socket.

System Cooling

The system is passively cooled, there are no fans. It is important that the Gateway has adequate ventilation. Take note when mounting the system that the vents on the label side of the unit are not obstructed. 

Connecting the Antennas

To install the antennas, remove them from the plastic covers and screw them into the antenna connectors.

Note: The antennas supplied with the kit are the only antennas approved to be used with the device. Use of any other antennas will void the regulatory approvals.

The diagrams below show the positions for the Zigbee and Cellular antennas. The Cellular antenna is only required on cellular enabled versions of the Gateway. Position A is for the Zigbee antenna (black colour), position B is for the 3G cellular antenna (grey colour) and Position C is for the auxiliary 3G antenna. The Zigbee and Primary 3G antenna should be connected on the opposite side to the RJ-45 Ethernet socket. The Auxiliary 3G antenna should be connected on the same side as the RJ-45 Ethernet socket. The other antenna connectors on the device are not required.

Note: In some cases the Gateway will be supplied with a USB dongle which includes the Zigbee antenna and it will not be necessary to connect the Zigbee antennas as per the instructions below. Simply insert the USB dongle into the USB port on the Gateway. The product code for this device is NGO-10.

Inserting a SIM card

Most countries worldwide have one or more operators that support 3G data services – please check with your local operator as to whether the operator supports HSPA, WCDMA or EDGE data services. All three are supported by the on-board module. Please obtain your SIM from your local cellular network operator (not all versions of the Gateway include a cellular module). The SIM may be easily inserted in the slot on the top of the Gateway. A SIM card must be added to cellular version of the Gateway to support cellular connectivity.

To install the SIM card, position the SIM so that the contacts are facing the non-labelled side of the Gateway as shown below. The notch in the SIM card should be on the lower left hand side, when looking towards the contacts. Gently push the SIM card into the slot. To remove the card, gently push down on the card and it will uninstall.

Indicator Lights

There are 10 indicator lights on the top surface. From left to right in the following order starting with the bi-color status light:

  • 1 bi-colour status LED, which is green for disk activity
  • Green + yellow + red LEDs for the 3G cellular modem
  • Green + yellow + red LEDs (not used)
  • Green + yellow + red LEDs for Zigbee

Turning the system On / Off

There is no on-off switch or button for the Gateway. To turn on follow these steps: 

  • Connect the power cord appropriate for your geography to the power supply brick.
  • Connect the power supply brick to the Gateway.
  • Plug in the power cord to the wall outlet.

Check that the green indicator light is on. This light is located at the top of the system. To turn off the Gateway, first log into the web interface, navigate to Settings > System and issue a command to shut down the system, then unplug it from the wall outlet.


The temperature in which the Gateway operates when installed must not go below 0°C or rise above 50°C. Extreme fluctuations in temperature can cause a variety of problems with the Gateway. 

The Gateway mounting location must provide sufficient airflow to maintain proper cooling. The mounting area must also include ventilation sufficient for exhaust of heat from the unit. Do not cover up air vents on the system. Also ensure that the unit is mounted in a location that is free from sources of vibration, contamination or physical shock, and that the Gateway is isolated from strong magnetic fields or other sources of interference.

Do not attempt to modify the AC power supply or use an AC power cord if it is not the exact type required. Ensure that the wall outlet that supplied power is properly grounded.

There is no reason to open the chassis of the Gateway under normal operating conditions. Doing so can be dangerous and can damage the Gateway product.
