Part Number: CAB104

You must connect pin 5 (the isolated ground) to the

ground of the connected external device.

The red stripe on the CAB104 cable indicates pin 1 on

the 10 pin header connector.

Ensure that you terminate the CTS signal if not required

by your application. This is commonly done by

connecting CTS to RTS. Failure to do so may result in a

loss of a performance on your Xtreme/104 Opto adapter.
