Hi Techno,
My old LC 2317 plug I have looked at and photographed. I hope I have attached the correct photo. Not able to see it in the preview for some reason???. Looking at at the wires straight on from the PC Com port where it plugs in, with hook on top, from left to right, orange, black, red, white. Looking down towards hook would be L to R, white, red, black, orange. This means the white wire would be towards the outside of the unit when plugged in. Got it? ha ha.
Hope this helps,
Irving
