LED operation Automatic MAC addressing
Controllers with Automatic MAC addressing functionality can
be identified by a label covering the MAC address rotary
switches. This information is also printed on the product label
available on the controller. When a controller with Automatic
MAC addressing feature is powered ON, can assign its own
unique MAC address ranging from 1 to 30. It can also coexist
with other unitary controllers whose MAC addresses are set
manually. The controller can automatically adjust the MAC
address at any time to avoid duplicate addresses in the
network. The automatic MAC address assigned through this
process is retained when the controller is powered OFF.
To disable Automatic MAC addressing, remove the label on
the rotary switches and set the switches to the manual
