Hardware Installation Chapter 2
The PC Receiver's Device ID high byte determines the maximum number of
devices supported in the network.
The Group ID and Device ID should not be modified except under exceptional
circumstances. One such circumstance would be operating two or more
independent PowerMonitor W250 networks in such close proximity that RF
interference with each other occurs. Please contact Rockwell Automation
support services for more information or if assistance is required.
