Table 3–2 identifies the 10-pin female plug pin names and the
corresponding programming mode.
1 The circuit board must supply V
CC(TARGET)
and ground to the
EthernetBlaster cable for the I/O drivers.
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.
