I know you didn't ask but a twisted overview follows:
It's all useful info.
A JTAG port is a way of programming Field Programmable parts, testing same, and testing PCB designs.
The Altera Cyclone 4 FPGA on the KnC controller has one of theese.
There is an unpopulated place for the JTAG connector on the power input end of the PCB.

Is this the kind of thing you're talking about? I had to get this to mess with the old BTC Garden blades. What is required to connect to the Altera Cyclone 4?
This? It only has up to CycloneIII listed but I can't see much else available:
