		+	In addition to the above 5 signals, you also need to connect V<sub>DD</sub> and Ground signals from the board.
		+	There are several interface cables that include all these pins and a few extra ones.
		+	The 14-pin (2x7) interface is known as the '''TI standard''',
		+	while the 20-pin (2x10) interface is known as the '''ARM standard'''.
		+	The Linkstation HG uses a 16-pin (2x8) interface which is standard for Freescale/PPC boards.
		+
		+	See [[Add Jtag Port]] for a list of cable vendors.
