Hi Theo, thanks for that.

Do you know what pin in the mini-din 8pin plug is attached to each color.

Is brown pin 1, red pin 2, orange pin 3, etc.

 

Many thanks

Hi Smithers1,

I never opened a 8-pin plug but usually the order is from top to bottom in the list so I asume you are right about the order brown = pin 1 etc.

I suggest that if you start testing the cable the first time just leave the white wire +5Vdc power not connected but use an external powersource for the GOT 5Vdc. Only connect the '-' from the 5Vdc to both GOT and PLC side (to close the loop). Aldough I think the port is galvanic isolated by opto-couplers you don't have the risk of destroying your FX PLC port due a wrong wire connection.

As you noticed, there is not much info on the net about this subject. Perhaps because the original cable is around € 20,- euro and only the real hardcore electronic guys heat up the soldering iron to make a cable theirselfs just because it is possible...:-) Don't take that personal but for that price I would just order a standard cable somewhere and save me the headache. It is up to you to decide. Succes!

 

Best regards,

Theo V.
