Had the same problem with a DAL sound card using aes/ebu. I purchased a model from All Pro Audio to get the correct pin out and had a new xlr fabbed using Neutrik parts. Not sure if this is necessary, but I went this path.
I looked up the ready made unit and I think it is listed below. If you use it, take it apart and remove the flux from the solder joints.
