The Calsense Ethernet communication device, model CS3-EN, offers a rugged and powerful option which provides connectivity with Calsense cloud-based Command Center Online using an existing Ethernet network such as a school campus or City with buildings that are linked via an Ethernet network.


  • Simple device set-up and configuration using the Calsense CS3000 Irrigation Controller

Ethernet Communications Details

The device ships from Calsense DHCP-ready so there’s often nothing required to start communicating. Simply connect it to an existing network using a category 5 (CAT-5) or better Ethernet cable and it automatically connects to Calsense server. If you prefer to assign an IP address statically, the device can be programmed directly at the controller using the controller’s keypad. Remote configuration over a network is also possible using a web browser.

The Ethernet port on the Calsense Ethernet communication option is autosensing so it automatically detects the type of Ethernet network it’s connected to and communicates at the highest speed it can. If the connection is lost, the device intelligently attempts to reconnect to the network automatically.
