Connecting to the Target

Connecting to the Target

The connection to the user target (UUT) board/system is done from the ScanTAP-4 Intelligent Pod
TAP connectors to mating connectors on the target. The ScanTAP-4 connects to the target via the
supplied 1:1 TAP flat cables, P/N 15310, 15311 or 15312. Figure 3-1 shows the top view of the
ScanTAP-4 box, including the four TAP connectors which are clearly marked: TAP 1, TAP 2,
TAP 3 and TAP 4.
