4.2 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.

Note: 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 and
composite video are 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).
