This is a replacement ICSP cable for the FORTE programmer. One end has a 2x8-pin female connector. This connector fits into the FORTE's programming connector.

Coming out from the 2x8-pin female connector are 10 wires of 150mm length. Each wire is terminated with a female square crimp connector. They can be fitted to standard 0.1" spaced male square post headers.

One of these cables is included with the FORTE. You only need to purchase this if you want to have a spare.
