It's a DB-25 to DB-9 RS-232 serial cable.   RS-232 ports originally used DB-25 connectors --> then PC serial ports started using DB-9's, and that's now much more common.

But I'm sure what you have is simply a serial cable the connects two serial devices ==> I suspect your "... tool with a parallel input" actually has a serial input :-)

... another reason I'm sure it's a serial cable:  40 metres is WAY too long for a parallel signal [the IEEE 1284 spec states a maximum cable length of 10 metres]   :-)    (but 40 metres is fine for an RS-232 connection)
