Ports

• Optical SPDIF audio output.

• DB9 Male RS232.
• DB25 Female for LED output and Switch input, as well as supplying 100mA of 3.3V power.

• 10/100 Ethernet Auto-MDIX and Auto-polarity switching.

• Two high speed USB host ports.
• DB15 VGA video connector.

• Triple RCA jacks for Component Hi-Def output (Y-Pr-Pb). This port can also output composite

video and S-Video.

• 3 stereo 1/8” mini plugs for audio output
• 2.5MM Power plug for 5V power input at 2.8A.

• IR receiver for 38KHz IR reception.

• Front panel LEDs for status.
• Front panel Switch for user input (Typically used to switch screen resolutions)

• 4 in 1 flash slot for SD/MMC/XD/MemoryStick flash cards.

• Compact Flash slot for CF cards.

Power Connector

The power connector on our board is rated at 5V @ 2.8A. The plug to go into our connector is standard
5.5MM plug, center positive, with a 2.1MM center pin hole. The power is over voltage protected and
reverse polarity protected with a 5W 5.6V zener diode.

Optical SPDIF connector

This connector accepts a standard SPDIF optical cable.

DB9 RS232 connector

RS232 connector is a male DB9. The HD600 is a DTE device (like a PC). The input to our chip accepts
up to +25V and -25V, so it is compatible with standard +12 and -12 volt signaling. The output of our chip
is rated at +5.4V and -5.4V typical which exceeds the voltage required by the RS232 specification. The
chip we use for RS232 only enables the RS232 transmit function when a valid RS232 voltage level is
detected on the receive line. This implies that the RS232 connector cannot be used for RS232 output only.

The baud rate is 9600, No parity, 8 data bits, 1 stop bit. No hardware or software flow control. The TX
and RX signal will look like this:
