The Sensor Seal Gateway is compatible with standard networking hardware such as routers and switches. An internet connection is required for initial setup and management via the web-based Gateway Manager but is not necessary for normal operation once configured.
The gateway uses UDP port 1818 to communicate with the Gateway Manager server. Ensure your firewall does not block outgoing traffic on this port while you wish to configure the gateway.
Note: The Sensor Seal Gateway does not currently support using IPv6.
Connection LED Status Codes
Gateway v1.1
| Connection LED | Description |
|---|---|
| Solid on | Connected to the Gateway Manager Server. The gateway has a functioning internet connection and can be managed remotely. |
| Fast blinking (200 ms on/off) | Default route resolved. The gateway has obtained an IP and can communicate with the local router. Local data transmission (e.g., UDP Broadcast) should work. |
| Slow blinking (150 ms on/off) | Link up. An Ethernet cable is connected, but the gateway cannot communicate with the router. |
| Solid off | Link down. No Ethernet cable is connected. |
Network Hardware Configuration Examples
Example 1
In this configuration, a 4G LTE router is used to supply internet connectivity to a Sensor Seal Gateway. The gateway is configured to send Sensor Seal measurements to a remote SSGSCP server hosted in the cloud.
The gateway is connected to the 4G LTE router via a PoE injector using two network cables. The router has its DHCP server enabled and assigns the gateway a local IP address, subnet mask, default route, and DNS server.
Since it has internet access, the gateway is able to connect to its Gateway Manager server and can therefore be configured via the Gateway Manager web interface.
Example 2
In this configuration, the Sensor Seal Gateway is connected to a PoE switch via a network cable. Another device is also connected to the network switch. Both this device and the Sensor Seal Gateway are configured to use static IPs. The other device is set up to continuously listen for incoming UDP packets on port 2828. The Gateway is configured to use the
UDPUnicast
connectivity type with the ASCII measurement format.
No router is used in this configuration and the Sensor Seal Gateway does not have any internet connection. To update the gateway's configuration, it needs to be connected directly to a computer with a link-local address and accessed using
