I did something similar, using a 40 pin IDE-type cable, then a 40 pin header plug on a bit of stripboard (strips cut between the rows of pins of course) with a few wires soldered to the right strips going to a DB25 connector. For a real kludge you can put solid-core wire into the holes of an IDC socket. So IDE cable as above, DB25 with solid core wire soldered to the right pins, then pushed into the holes on the free end of the cable. Not for 'use' but it will work for testing. Of course the OP has the current loop cable. You can remove the contacts from 40 (or 44) pin socket housing and re-arrange them. You have the jumper wire for the serial pin, you need to move one end of that. And a length of 6 way cable with said contacts on one end -- strictly you only need 3 for the RS232 one. So you could hack it about, cut of the 8 pin mate-n-lock and fit a DB25. But pehaps you want to keep the current loop cable too. -tony
