Recommended Target Connectors
28
Figure A-4 shows a typical schematic of the target TAP connector with termination resistors. The
1K pull-up resistors should connect to the target Vcc supply corresponding to the interface voltage
(programmable on the PXIE-1149.1/4E from 1.25 to 3.3 V). Recommended resistor values are +/-
5%.
