Ethernet (LAN)
Enable DHCP
Click on the radio button to enable DHCP if you want the controller to obtain its IP address from the
local area network. This option only works if the controller is connected to a LAN.
Ethernet IP Address
When a controller is attached to a network, your IT Administrator needs to assign it an Ethernet IP
address. When you want to communicate with the controller from your PC on the network, you go to
your Browser and type in the controller’s address. Type that address into the text box.
Ethernet IP Netmask
When a controller is attached to a network, your IT Administrator must also assign the IP Netmask.
Type the number assigned in the text box.
Ethernet Gateway
When a controller is attached to a network, your IT Administrator must also assign the Gateway. Type
the number assigned in the text box.
Network Mode
If you have purchased the software to allow networking of controllers via Ethernet, use the pull down
arrow to select the role that this controller will serve on the network. If it is not part of a network of
controllers, select “Independent”. If it is the Master, select “Master”. If it is the Slave, select “Slave”.
Once the network mode has been selected, the power to the controller must be cycled in order for the
change to take effect.
Network Detection (only appears if the controller has master networking activated)
Click on the Detect Network button of the Master Controller and it will look at all of the devices that
are connected to it, determine which devices are its slaves, and refresh the Sub-Network frame in the
lower left corner of your browser with all of the slaves detected.
