Circuit Board Header Connection

The circuit board's 10-pin male header, which connects to the EthernetBlaster cable's 10-pin female plug, has two rows of five pins. These pins are connected to the device’s programming or configuration pins. Figure 3–3 on page 4 shows the dimensions of a typical 10-pin male header.
