harman/kardon Download Procedure

HD970 June 05

To: harman/kardon Service Centers

Models: HD970/230 Subject: FIRMWARE DOWNLOAD

Item needed: CD-R disc, writer program/CD-R writer and two files include a txt file and a BIN file

The BIN file contains the servo firmware and the txt help the unit to download the software.

1. Please add all the files to a blank CD-R as CD-ROM Mode 1 format.(standard) Caution: If you make CD-R download disc as CD-ROM XA mode, new firmware will not be downloaded.

2. When your adding files to the blank CD-R, please do not change the file's name.

3. When you are ready to make a CD-R download disc, you should make CD-R session closed. That is, CD-R download

disc must be a single session disc (finalized). Always write the CD-R in lowest speed possible.

4. Power HD970 on and make sure the unit is 100% functional before start any upgrade.

5. Eject the tray by OPEN /CLOSE and insert the CD-R

6. Close the tray with OPEN/CLOSE or pushing tray manually.

7. Wait until tray open itself. The display will show the status of the download.

8. Remove the disc.

9. Unplug the power cord

10. Plug the power cord, power HD970 on and ensure the units are working.

The BIN file contains the servo firmware and the txt help the unit to download the software.

1. Please add all the files to a blank CD-R as CD-ROM Mode 1 format.(standard) Caution: If you make CD-R download disc as CD-ROM XA mode, new firmware will not be downloaded.

2. Please type the volume name of the CD-R as "ATPLDR_DOWN" exactly.

Caution: you must type the volume name in capitals by all means.

3. When your adding files to the blank CD-R, please do not change the file's name.

4. Please add the BIN file with the 40Mbytes TXT dummy file. Because attached file's data area is, sometimes, too small for servo to spin up.

5. When you are ready to make a CD-R download disc, you should make CD-R session closed. That is, CD-R download

disc must be a single session disc. Always write the CD-R in lowest speed possible.

6. Power HD970 on and make sure the unit is 100% functional.

7. Eject the tray by OPEN /CLOSE and insert the CD-R

8. Close the tray with OPEN/CLOSE or pushing tray manually.

9. Wait until tray open itself with "READING" written in the display.

20 Output ZEROR Right Channel Zero Flag Output. This pin goes high when the right channelhas no signal input or the DSD mute pattern is detected.

21 Output ZEROL Left Channel Zero Flag Output. This pin goes high when the left channel hasno signal input or the DSD mute pattern is detected.

22 Input MUTE Mute. Assert high to mute both stereo analog outputs. Deassert low for nor-mal operation.

23 Input PD/RST Power Down/Reset. The AD1955 is placed in a reset state and the digitalcircuitry is powered down when this pin is held low. The AD1955 is reset onthe rising edge of this signal. The serial control port registers are reset to thedefault values. Connect high for normal operation.

24 Input CDATA Serial Control Input, MSB First, Containing 16 Bits of Unsigned Data. Usedfor specifying control information and channel-specific attenuation.

25 Input CLATCH Latch Input for Control Data

26 Input CCLK Clock Input for Control Data. Control input data must be valid on the risingedge of CCLK. CCLK may be continuous or gated.

27 Input MCLK Master Clock Input. Connect to an external clock source.
