Network Address Switch Assemblies
You must set two switch assemblies to configure your adapter module with its
unique network address. You access these switches through the top of the module.
The following figure shows the location of the switches. These switches are read on
power-up to establish the network address of the module. Network address switch
settings are described on page 7.
Determining Power Requirements
The ControlNet adapter module requires a maximum backplane current of 900mA
at 5VDC. Remember to add this amount to other current requirements for your I/O
