ADDER CUSBEXT100 Quick Start Download Page 1

The Adder C-USB modules allow you to extend the distance between a USB peripheral and your computer by 
up to 100 meters.  
The local module connects to a vacant USB port on your computer. You then connect your USB 1.1 or 2.0 
peripheral to the remote module which is linked via CAT5e, 6 or 7 cabling (not supplied) to the local module. 
A power adapter is provided to supply either the local or remote module, whichever is most convenient.
In operation, the C-USB modules remain transparent to allow your USB peripheral to work as expected.
