Hi, am looking for flex strip 4pin to 3pin adapter cable for programming (click for image link below), am buying coz the one i have takes several attempts or never detects my HA “siemens NITRO 16 CIC”, i have the socket cable, thank you.
look on E-bay
Try cleaning the copper contacts with a soft clean pencil eraser and don’t push the cable in too far.
Actually the tip of the copper somehow was bent it seems and there is a small gap in the middle copper lane, see the below image. When i striaghten the tip of the cable it works, but have to be very still when tuning 
cant relay on this. Will try the pencil eraser method, and am looking to buy new flex cable on ebay, is this the correct model name for siemens “flex connect CS53”?
Looks like you found your problem. Yes I believe that is the correct model number.
Thanks for your information. I found the cable in ebay.com from this seller “spajka”, i hope he has more quantity for those who are searching. spajka on eBay
