Node Address Select the ControlNet node address of the 1747-SCNR module by
setting the two 10-digit rotary switches on the top of the scanner.
You can select a node address from 01 to 99 for a device on a
ControlNet link. Zero
(00) is not a valid node address.
IMPORTANT
Since 00 is the default value from manufacturing, you
must change the node address when using the
scanner for the first time. Turning on the scanner
with the node address set to 00 clears the module
memory back to the factory default.
