1625 DB25F I/O Adapter Cable

The 1625 DB25F I/O Adapter Cable connects all the pins (but the pin 1) of a 26-pin dual-row 0.1" pitch connector to a 25-pin female SubD connector fitted into a standard-profile PC bracket.

Usage with Internal IO2 connector

Applies to:

The adapter brings the second set of I/O lines and the +12V power output to a bracket-mount SubD connector. The pins are assigned as follows:
