BrightSign HD120, HD220, HD1020 • • HDMI connector Power plug for 5 V power input at 3 A Power Connector The power connector on this board is rated for 5 V at 3 A. The plug for the connector is a standard, center-positive 5.5mm plug with a 1.65mm center pin hole. DE9 RS-232 Connector The RS-232 connector is a male DE9. Like PCs, the BrightSign HD series of players are DTE devices. The input to the chip accepts a range between +30V and -30V, so it is compatible with standard +12V and -12V signaling.

BrightSign HD120, HD220, HD1020 ENVIRONMENTAL AND POWER USAGE The HD120, HD220, and HD1020 players are designed to be used between 0°C and 40°C, at 90% maximum relative humidity, non-condensing. The power supply on the BrightSign HD series is 15 W and 5.0 V at 3 A. These players will use approximately 1 A of power when playing a 720p or 1080i MPEG2 HD source file. Note: 1 A at 5.0 V is approximately 5 W. There is 2 A of additional available power that can be used by peripherals connected to a player.

BrightSign HD120, HD220, HD1020 THEORY OF OPERATION Power Supply There are five voltages present in the player: 5 V, 3.3 V, 2.5 V, 1.5 V and 1.2 V. 5 V comes in from the power connector and is used directly for the USB. 3.3 V is created from 5 V by a switching regulator. Similar regulators are used to create 2.5 V for the DDR SDRAM and 1.2 V for the CPU core voltage. Reset The HD120, HD220, and HD1020 players have a Low Voltage Reset circuit. This circuit will hold the RESET_L signal low until a valid 3.
BrightSign HD120, HD220, HD1020 SDRAM The HD120, HD220, and HD1020 players each contain one DDR SDRAM device. When the BCM7208 boots, it will copy the code from the NAND flash device into the SDRAM and then execute the code from the SDRAM. The SDRAM runs at a clock rate of 666MHz, with a data rate of 1333MHz. Serial Port The player has a built in UART that communicates with the RS-232 level shifter. The MAX232 creates valid RS-232 voltage levels for the transmit pin by using a capacitive voltage switcher.
BrightSign HD120, HD220, HD1020 Green flash activity Flashes any time there is CPU activity. Yellow update Flashes when the board is being upgraded. Red status Flashes a certain number of times to indicate which error is occurring. The flash codes are described below. 2 Unspecified error 3 Network recovery script is preparing to run on a device configured for network recovery. 4 No upgrade file found 5 Failed to load kernel module 6 Board is not capable of running the current firmware version.
BrightSign HD120, HD220, HD1020 SDHC/SD Flash Slot The SDHC/SD flash slot supports SDHC and SD flash cards. NAND Flash BrightSign players have a built-in NAND flash. All the code for the player is stored on the NAND flash. It may also be possible to store some content on the NAND flash, which is connected directly to the BCM7208. Ethernet The 10/100 Base-T Ethernet is implemented on the HD120, HD220, and HD1020 by directly interfacing with the BCM7208.
