No. : DISP CODE ID Dev. : Device ID SIG. : CODE SIG ID TYP. : CODE TYPE ID Ver. : Version 6 Note: Step4, 5 is to check if CPU software is capable of DSP code. "Software Type No" is to show what "DSP Code Group" CPU is capable of. And vice versa. Step 8 is to manage the 16 codes for DSP. · When the unit is once turned into Service Mode, the unit keeps this mode until the main power is turned off. (Turning into stand-by mode does not make it quit from Service Mode.) When the unit quits from Service Mode, Information in the memory is also cleared and the unit returns to the status when it is out from the factory. Product Reset To reset the back up memory of the unit into the default status, follow the procedure below. 1. 2. Turn of the unit and press 7.1CH INPUT and MULTI button simultaneously more than 1.5 seconds. After "DEFAULT" is displayed on FLD, power is turned off once and turned of again, EEPROM is cleared to the default status, µ-com is reset and the unit returns to the normal status. (Software Serial Number will not be cleared.) Note: When the unit is shipped from the factory, the procedure above must be done to set the unit to initial status after the tests. Personal notes: 7 5. SYSTEM ERROR When the microcomputer detects a trouble, the following information is displayed on the FLD. · After the error contents indication, Surround Mode is initialized and returned Factory mode. · The contents of the ERROR indication are the followings. 1. Trouble in DSP If communication with DSP is troubled more than 2 seconds. C H E C K D S P C H E C K D S P Indication is keep and sound is mute. 2. Trouble in DSP Code The trouble of DSP Code was found. C H E C K D S P R O M C H E C K D S P R O M 3.

UPDATE FIRMWARE Software for CPU and DSP can be updated. Have update application software. ("UpgradeDSP.exe" and "H8Download.exe") There are two mode of download, regarding to the target of software as bellow. Mode 1: Update DSP's software to 4M Flash-ROM. This mode is to update the software for DSP. The target devise is 4M Flash-ROM (IC20) on CUP11706Z (DSP PCB). HT-AS2000 needs to be set update condition, by three front keys. Mode 2: Update CPU's software to internal Flash-ROM. This mode is to update the software for DSP. The target devise is internal flash ROM of CPU (IC28) on CUP11706Z (DSP PCB). HT-AS2000 needs to be set to writing condition, by pushing internal switch from back-panel. The following items are required for updating. RS232C Dsub-9 pin cable (female to female/Straight type) Windows PC (98, NT, ME, 2000) with RS-232C port. Update software to CPU. Update software to DSP. Use RS232C Dsub-9 pin cable (female to female/Straight type) to connect PC and the unit. COM port on PC needs to be set by dialog box for each program. COM port can be set from COM1 to COM5. Download Firmware for DSP (Mode 1) 1. Put the "DSP upgrade" folder into anywhere on your PC's hard disc. 2. 3. 4. 5. Connect PC and the unit with the RS-232C cable. Turn on the unit. Press ENTER, MUTE and T-MODE buttons simultaneously more than 5 seconds to turn the unit into Loading Mode. "LOADING MODE" will be shown on FLD. 9 6. Launch "UpgradeDSP.exe" on PC. Note: yy_mm_dd is release date of software. 7. Click Port setting, and select the COM Port No. 8. Set the Baud Rate to 38400 then click Start communication button. 10 9. If the connection is made successfully, a dialog box saying "Success to connect" appears and "CONNECTED" is displayed on FLD. 10. Click Send the DSP codes button on the dialog box. Progress status of updating will be shown on PC and LOADING is displayed on FLD. 11. If updating is completed successfully, "COMPLETED" is displayed on FLD. And a dialog box saying "Finished the DSP code transmitting" appears. Click OK and then Application is closed automatically. 12. Turn off the unit. Download Firmware for CPU (Mode 2) 1. Put the "CPU update" folder into anywhere on your PC's hard disc. 11 2. 3. Connect PC and the unit with the RS-232C cable. Insert a thin rot to the hole and push the switch (SW10) inside to turn on the switch. Hole of rear panel 4. Turn on the power of the unit. Note: When the unit is into boot mode, stand-by LED is not lights up. 5. Launch "H8Download.exe" on PC. 6. Click Set Ports , and select the COM Port No. 12 7. Click other files... button in the dialog box to specify the file (SR5500_yymmdd.mot) to be uploading. yymmdd in filename is release date of software. 8. Click Connect button. If the connection with the H8 µ-P is successfully made, a dialogue box saying "Success to the H8 micro processor connection" appears. If the connection fails, error message will appear. 9. Click Send button to start update. 10. If the firmware is updated successfully, a dialog box saying "Finished the firmware program sending" appears. 13 11. Click CLOSE button to close the application. 12. Disconnect Mains power cord. 13. Turn off the internal switch that has been turned on at step 3. 14. Turn on the unit. Firmware Version Check To check the versions of the firmware, see "Microprocessor (CPU), DSP Version and FLD Segment Check Mode" in "SERVICE MODE" section. 14
