The circuit board must supply VCC(TRGT) and ground to the ByteBlaster II cable for
the I/O drivers.
Circuit Board Header Connection
The circuit board’s 10-pin male header has two rows of five pins connected to the
device’s programming or configuration pins. Figure 2–3 shows the dimensions of a
typical 10-pin male header.

Although a 10-pin surface mount header can be used for the JTAG, AS or PS
download cable, Altera recommends using a through-hole connector due to the
repeated insertion and removal force needed.
