Ensuring C10 internet connectivity

Modified on Thu, 02 Mar 2023 at 03:01 PM


The temperature measurements are wirelessly sent to a central point, which is the Gateway (E.g. C10). This gateway forwards the measurements onto the internet. It is typically located in the office, and requires a 220V power outlet and a network connection.

This document describes how to successfully connect the Gateway to the server. The overview should be sufficient for a novice user, while the detailed description (refer to the last page) can be shared with the IT staf 

The Gateway attempts to create an outgoing internet connection to the RmoniWeb server on the internet. So it effectively behaves like a computer on your network, trying to reach a website on a server. This means it must be connected on your network and must be allowed to connect to the server.


Things to check in advance

Make sure to check the following things during an installation:

  • Network connection
    Make sure a network port is available in the office. Check if this network port is connected to your network. E.g. plug in a computer, switch off the Wi-Fi and try to surf on the internet. If this doesn’t work than check if the network port is connected to the network switch in the patch panel.

Things to check during installation

Make sure to check the following things during an installation:

  • Network connection
    Plug the gateway into the network port, plug in the power adapter. Check if the orange light (at the network connector) is on (continuously). Is this not the case? Check the cabling or try another port.

  • Server connection
    Check the LEDs on the front of the gateway. the green led (server) will blink for a few seconds before it turns on green continuously to indicate a successful connection to the server. Is this not the case? Please check out our detailed description below and ask your IT staff for assistance when required.

Detailed IT description

The Gateway has to receive an internal IP address on the LAN and also has to be allowed to create an outgoing TCP connection to the RmoniWeb server. The requirements are: :

  • IP address
    The Gateway will ask an IP address via DHCP by default. If this is not supported on your LAN, please provide an IP address which can be pre-programmed into your Gateway.

  • MAC address
    If the MAC address has to be white-listed on your LAN, please make sure to look for the Ethernet MAC Address which is noted on the log-in documents. Do not use the MAC address sticker on the side of the gateway (this is a Zigbee MAC address).

  • TCP connection
    The gateway will try to make an outgoing connection to dns4.sensor2web.com at port 6337. Please, see below if DNS is not supported.

  • DNS
    If DNS is not supported on your LAN, than please let us know in advance. We will than pre-program the target IP address at port 6337.

  • Firewall
    Please, add the following firewall rule if your firewall blocks outgoing TCP connections:

ALLOW [RAW TCP] from [internal IP] to dns4.sensor2web.com at port 6337

  • Ethernet
    Standard 10/100 Mbps Ethernet raw TCP

  • Bandwidth
    The sensor measurements are very small, typically less than 100 bytes sent every 5 minutes. So even with a sensor network of 20 nodes, the data traffic generated is neglectable.
