Board 12V Input Power
The VC7203 board receives 12V main power through J2 (callout 3, Figure 1-2) using the
12V AC adapter that ships with the board. J2 is a 6-pin (2 x 3), right angle, Mini-Fit
connector.
Caution!
When supplying 12V through J2, use only the power supply provided for use with this
board (Xilinx part number 3800033).
Caution! Do NOT use a 6-pin, PC ATX power supply connector with J2. The pinout of the 6-pin, PC
ATX connector is not compatible J2 and the board will be damaged if an attempt is made to power it
from a PC ATX power supply connector.
