ETP 4G TeeBoxes

Notes for Engineers

Both connectors from the antenna should be plugged into the Netgear LB2120 to allow for diversity receiving. The antenna should be positioned on the outside of any enclosure if possible. The LEDs indicate signal strength of the 4G signal.

The Meraki Z3 Internet port is set to DHCP to automatically pick up an suitable IP address from the Netgear LB2120. This will be in the range 172.16.10x.yyy where x is the system number (currently 1 – 8).

The Intel NUC can be connected to any port on the Meraki Z3 and should be set to DHCP to automatically pick up a suitable IP from the Z3. This will be in the range 172.16.x.yyy where x is the system number (currently 1-8).

The Victron Multiplus inverter monitoring adaptor must be connected to port 5 of the Meraki Z3 as it requires PoE. The IP address of the adaptor is hard coded and can be found by pressing the button on the adaptor. The IP address must be appropriate for the system it is connected to. The sensor cable from the monitoring adaptor should be connected to the COM and NO connector of the Victron Multiplus inverter.

The NUCs are running a custom kiosk operating system called Porteus Kiosk. These displays are controlled centrally by accessing the Kiosk Server using VNC or Screen Sharing. For the URL needed to access this dashboard, please contact CT.

As this is a cloud based server, hosted at CT, the NUCs themselves do not need static IP addresses, only internet access.

The custom operating system can easily be installed on site if a NUC fails, or has been installed with the incorrect operating system, this can be fixed by using the installation instructions included later in this post.

The Netgear LB2120 4G Router and the Meraki Z3 are monitored by the CT monitoring system, however this may require some configuration to ensure the equipment actually on site is being monitored, and old devices are removed.

The monitoring home page, which displays any problems present, can be accessed at etpmonitoring.ct-networks.com. By logging in to the platform you can administer this monitoring and who receives email notifications. Full instructions and user manuals are included in the web pages of the monitoring system, just select the Documentation tab.

This monitoring system is still in development and any feature requests or bugs should be reported to CT.

For most deployments CT will be using Vodafone M2M SIM cards which are designed to have better service from mobile phone towers. All these SIM cards have unlimited roaming data contracts attached to them.

To fully utilise these functions, the Netgear LB2120 4G routers must be configured with a custom APN, so the SIM cards connect correctly to cell services.

To confirm this, log in to the Netgear LB2120 and select Mobile -> APN. If the Vodafone M2M APN has not been added already, simply create a new APN and fill in the details below. The username and password are both ‘web’
