Setting the Node Address
Switches Set the adapter Node Address switches ( Figure 2.1 ) by rotating the switches
to the desired value for each digit.
Important: Each node on the ControlNet network must have a unique
address. Set the node address before power is applied because
the adapter uses the node address it detects when it first
receives power. To change a node address, you must set the new
value and then remove and reapply power to (or reset) the
adapter.
