USB-1096HFS User's Guide Specifications

Note 1: The daisy chain power output option allows multiple MCC USB Series boards with a USB hub output port

to be powered from a single external power source in a daisy chain fashion.

The voltage drop between the input of one module and its daisy chain output is 0.5 V maximum. You should

plan for this voltage drop when configuring a daisy chain system to assure functionality of the last board in the

chain.
