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.

BrightSign HD600 Theory of operation Power Supply The HD600 has a four voltages present. These are 5V, 3.3V, 2.5V, and 1.2V. 5V comes in from the power connector and is used directly for USB, the video filter chip, and the optical SPDIF chip. 3.3V is created from 5V by a AMC2596-ADJDDF switching regulator. Similar regulators are used to create 2.5V for the DDR SDRAM, and 1.2V for the PNX1500 core voltage. Reset The HD600 has a Low Voltage Reset circuit made up of a ADM809SART.
BrightSign HD600 Video Encoder and Filter The PNX1500 streams decoded video out of the VDO port using a double data rate clock. In other words, 12 bits of video data is clocked out of the PNX1500 on the rising edge of the VDO_CLK signal, and on the dalling edge as well. This allows the PNX1500 to output 24 bits of data at a 74.25MHz rate, using only a single 74.25MHz clock and 12 data lines. The SAA7105 video encoder takes the VDO data in and sends the data straight to the video DACs in HD mode.
BrightSign HD600 CF flash slot The CF flash slot is connected up in TRUE IDE mode, and it uses the PNX1500 IDE mode on the XIO bus. The chip select for the CF slot is XIO_SEL1. two 74LVC245 bidirectional buffers isolate the databus of the CF from the XIO databus, so that the CF card can be hot plugged. A 74LVC244 chip buffers the other CF signals, again so that the CF card can be hot plugged. The PNX1500 won’t attempt to access the CF slot unless it first detects that a CF card is present.
BrightSign HD600 Flow Chart: (for Repair Center Use) (1) Power Start No LEDs on Is the Output power adapter 5V DC? No Replace Power Adapter Is the Voltage of No Check D22 & D23 for shorts L76 = 5V? Yes Is the Voltage of No Check U30, L73, U20 No Check RP5 TP43 3.3V? Yes Is the Voltage across D23 ~= 2V? Yes Replace D23 This information applies to a product under development. Its characteristics and specifications are subject to change without notice.
BrightSign HD600 (2) Power LED comes on, no serial port output No serial port output Is there 2.5V DC at TP19? No Check U22, D11, L55 Is there 1.2V DC at TP42? No Check U27, L59, D18 No Check U26 Is RESET_L high at No R197 after powerup? Check U36 Yes Is there 27MHz at R50? Yes Yes Is SYS_RESET_L high at R7 after powerup? Yes No Check U23, Check I2C bus for shorts, Check PNX1500 U18 Check U9 for good program and good solder joints, This information applies to a product under development.
BrightSign HD600 (2) Power LED comes on, 1 or more green LEDs come on in sequence from left to right Start Green LED1 or LED2 No , rest off? Green LED3 on, rest off? No NOR flash boot failed, Check SDRAM U19, U35 and NOR flash U9. Check XIO bus for shorts.
BrightSign HD600 (3) Power LED comes on, RED led comes on plus 1 or more green led stays lit. Start, RED led on NOR flash read failed, NOR flash U9 contents. Try updating NOR flash with CF card. Green LED1 or LED2 No or LED3 or LED4 on? No Green LED5 or LED6 or LED7 on? Check CF socket, U3, U4, U6, XIO bus Yes Green LED8 or LED9 on? No NOR flash read failed. Try updating NOR flash with CF card. failed. Check U9. No NOR flash write failed. Check U9.
BrightSign HD600 (4) Power LED comes on, 1 or more green LEDs come on in sequence from left to right, and then go out. Red LED stays out. Serial port tests are in order. Connect a PC to the HD600 using a null modem cable (Wire up 2-3, 3-2, 5-5). Set the terminal program to 115,200 N,8,1. A) If the serial port is not working, then check U2 and P2. B) Use LEDTEST command to test each LED.
BrightSign HD600 VIDEOMODE 1024x768x60p VIDEOTEST ATA:/true.vob (You can use your own VOB file or MPEG2 file for this test, on the CF card) If the RGB video fails to play, check the following: U25, U24, U21, P9. While playing RGB in 1024x768 mode, the following signals should be present: •Videoclock at pin 20 of U25 should be 65MHz. •HSVGC and HSYNC should have 48.
