Connect the ribbon cable to the P102 on the P3SVGA board as shown in Figure 12. Place the boards
on a firm surface to avoid over-stressing them. Be certain that:
1. The connector is aligned so that that it covers all of both rows of pins.
2. The ribbon cable is oriented so that the red wire is at the pin 1end of the connector as
shown. Your ribbon cable may exit the connector toward the board instead of away from it
as shown here. That is not a problem as long as you orient it to place the red wire at the pin
1 end as shown.

Mount the boards on the rear panel as shown in Figure 13. Start all of the jack screw nuts before
tightening them. Do not over-torque them. It is possible to twist the head off of the threaded section,
especially if you use a wrench.
