BrightSign HD600
Overview
This hardware reference manual specifies the hardware interfaces on the HD600, as well as providing a
guide to troubleshoot the hardware of the HD600 for in-field service. This manual will not describe any
software functions.
The BrightSign HD600 is a device that can be used to drive a variety of HDTV and computer monitors
for digital sign and kiosk applications. As well as driving the Video Display, the HD600 has many
different control interfaces built in to allow the sign to be controlled.

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:

DB25 Switch/LED connector
The Switch/Led connector is a DB25 Female. This connector is used to allow the HD600 to control
external LEDs or other devices requirind 15mA of current or less. Connect the LED outputs to the LED
ANODE and connect LED CATHODE to ground. If you want to connect up some other device then the
output is capable of sourcing or sinking up to 24mA at 3.3V, but we do have a series resistor of 100 Ohms
in each line. This connector also allows connecting up external contact closures to ground. In order to
connect a switch, connect one side of the switch to the switch input, and connect the other side of the
switch to one of the ground pins on the DB25 connector. Finally the connector can also supply 3.3V at up
to 100mA to an external device. The 3.3V output is polyfuse protected. The DB25 has the following
pinout:
pin Description pin Description
1 LED 5 output 2 Ground
3 LED 2 output 4 LED 0 output
5 Button 11 input 6 Button 9 input
7 Ground 8 Button 6 input

11 Ground 12 Button 1 input
13 +3.3V output 14 LED 4 output
15 LED 3 output 16 LED 1 output
17 Ground 18 Button 10 input
