The goal is to buy a Mini-DIN 6-pin extension cable, open the cable (i.e. at mid-point) and reverse the wires connected to pins 3 and 4.
This attempt failed because the Mini-DIN 6-pin extension cable did not have 6 wires. It only had 4 wires.
Just thought I would post this failure in case your project has failed for similar reasons.
****Sorry Pictures got lost ****
Here’s the Mini-DIN 6-pin extension cable. Note that it has the same cable connections as a computer keyboard or mouse.
Tools - Cutting Pliers and Wire Stripper:
These were too small for the Wire Stripper. I stripped these manually:
Testing Continuity/Ohms with a multimeter to find out which wire is connected to which pin. I bought this cheap multimeter at Harbor Freights for $2.
Finally, here’s my reason for failure. The pin connections matched the Standard CS-44 Cable Connections chart except for the Black wire (see picture below). I can reverse green/white wires, but that will leave me without a pin#2 connection. Drat! I have to start with a cable that has 6 wires, not 4.
