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.

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

Wire # IDC Pin # SubD Pin # Signal Name Signal Description
1 1   GND Ground
2 2 1 GND Ground
