Calsense
Requirements
To connect a Calsense Ethernet device to your network, the following is required:
• An existing Ethernet network
Note: Gigabit and greater networks are only supported if the network auto-negotiates down to
100 Mbps.
• A network that uses Internet Protocol version 4 (IPv4)
Note: Internet Protocol version 6 (IPv6) is not supported.
• Outbound TCP connections via port 2000 allowed through any firewalls or routers between the
central computer and controller
• A dedicated IP address - this can either be assigned by a DHCP server using IP reservations or
statically
Note: Dynamic IP addresses without IP reservations are not supported.
• Category 5 (CAT-5) or greater cable to connect the device to the network
• A maximum cable length of 100 meters (328 feet) between the controller and a switch or router
Phone Modem (model -R)
The Calsense Phone Modem communication option (model -R) enables a computer running the Calsense
Command Center software to communicate with a controller using an analog phone line. Figure 25
shows an example of a single computer communicating to a controller using a phone modem.
This option includes an embedded 56.6 Kbps V.92 modem with an integrated RJ-11 phone jack. This
modem accepts incoming calls from the Calsense central software, allowing the user to remotely
monitor and manage their irrigation systems without the need to purchase additional equipment or pay
licensing fees.
Benefits of choosing the phone modem option are:
• Uses existing analog phone lines in the field
• Does not require any additional equipment or licensing
