3304 HD26F I/O Adapter Cable

The 3304 HD26F I/O Adapter Cable interconnects a 26-pin dual-row 0.1" pitch connector to a 26-pin 3-row female High-density 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:
