*1. Besides the Additional I/O Power Supply Unit, some other Units can supply I/O power to the NX bus. For
example, you can use a Connected Communications Coupler Unit. If you use this Unit to supply I/O power
to the High-speed Analog Input Units, the Additional I/O Power Supply Unit is unnecessary. The Additional
I/O Power Supply Unit is also unnecessary if you do not use the trigger inputs of the High-speed Analog
Input Units.
