I bought this because I needed this and could not get it locally.

In case it isn’t clear in the description this is a Straight Though cable, for use with an old external modem or similar, if you need a cable for programming or linking two computers together then this ain’t for you.

This cable is not properly pinned for cnc NC file transfer and would require you take it apart and modify and you’re better off buying the connector ends and making your own cable. Wish I had known this before buying so I take part in the fact it won’t work.
