Connectors
Caution:
Many of the connectors provide operating voltage (+5V DC and +12V DC, for
example) to devices inside the computer chassis, such as fans and internal peripherals.
Most of these connectors are not over-current protected. Do not use these connectors for
powering devices external to the computer chassis. A fault in the load presented by the
external devices could cause damage to the computer, the interconnecting cable, and the
external devices themselves. This section describes the board’s connectors.

The on-board 14 pin D-Connector J2A1 (#6) supplies the necessary signals to support
the Composite, S-Video, and Component TV standards. Component video &
Composite video is connected to the development board using a D-connector to
Component Video cable (with three RCA receptacles at one end and D-mating
connector on other end) (not included in the kit). S-video is connected to the board
using a D-connector to S-Video cable (with 4-pin DIN connector one end and D-
mating connector on other end) (not included in the kit).
