This is a programming cable used by the Ronetix PEEDI series of debugger/programmers.
This cable is for the 14-pin JTAG connector used by boards with MIPS32-based processors, e.g. PIC32, ADM5120, Atheros AR6001XL.
One of these cables is included with the purchase of a MIPS32-licensed PEEDI (or add-on programming license). Use this order page if you want an extra cable.
