where to purchase C37FF-x or C37FFS-x cable?

[xing]

Hi, I recently purchased a PCIe-DAS1602/16 board. According to the product manual, the recommended cable for the analog output connector is either the C37FF-x or the C37FFS-x (shielded) cable. However, both cable options seem to be discontinued when I attempt to make a purchase online. How can I purchase the cable, and/or could you suggest alternative cables, if these recommended cables cannot be obtained?

You can get 37-pin cables from L-COM. Here's an example of a 2.5 ft female cable.
