AO8 INSPECTION 1. Range of Applicability These specifications apply to the AO8 and AO8-DA8. 2. Preparations 2-1. Conditions For details on the connection method, refer to the Test Program Specifications KES-92653. Unless otherwise specified, the conditions are as follows. · Set the INPUT SELECTOR switch to A. · Set WORD CLOCK IN 75 Ω to ON.
AO8 (1) Fs = 51.12 kHz (48 kHz + 6.5 %) · Set the function generator to 51.12 kHz. · Test listen for 30 seconds at all the output terminals and verify that there is no noise. (2) Fs = 39.69 kHz (44.1 kHz -10 %) · Set the function generator to 39.69 kHz. · Test listen for 30 seconds at all the output terminals and verify that there is no noise. 3-5. 4. Firmware Load Test Check that it is possible to load the firmware as in 2-2. using the Input B terminal.
AO8 TEST PROGRAM A. Preparations for Inspection • Writing the firmware This equipment requires firmware. When there are changes to the manufacturing processes and program for this equipment, it is necessary to download the new firmware to FlashRom from a PC. (If there is no firmware loaded or its checksum does not match the correct value, when the power is first switched on the LED on UNC flashes at one second intervals.) The only sheet for which the firmware must be downloaded is UNC.
AO8 Software used: Version used: PM1D inspection PC software in PM1D system software PM1D system software component files with the version number listed on the cover sheet. (Managed with the already drawn CD-R assembly drawing (3JL-XY714A0).) For details on the preparation and execution methods, refer to the CS1D Test Program Specifications. Before starting inspection, refer to version.
AO8 C. Inspection Items The inspection items are as below. Details of the inspection items are shown on the following pages. * However, 128 Fs Sync must be normal for the DSP to operate, so there is no special check item. No. 1 2 3 4 5 1. Item AO8 - UNC test AO8 - IFC3 test AO8 - SLOT test AO8 - IPC4, LED2 test AO8 - IPC2 test AO8 - UNC Test This test checks around the AO8-UNC. OK/NG display for the page as a whole Displayed when all the checks have been completed. 1.
AO8 3-1. AO8 - Slot [Initial] Test Stopped the moment an actual Addr.BusTest or DataBusTest NG appears. Checks slot operation by checking the minimum necessary number of pins. The results for each slot are displayed in order from the left. A mark is made for each check to show the progress of the checks. (Blank: Not yet checked; 0: Normal; 1: Abnormal; N: No response) NG example 3-1.
AO8 4. AO8 - IPC4, LED2 test This test checks around the AO8 - IPC4 and LED2. 4. AO8-IPC4, LED2 Test For the 75 item, the pop-up box is displayed below and the inspector judges visually on the oscilloscope. OK * Input Selector SW * W.CLK 75ohm SW * 7segments LED * W.CLK In 48 kHz + 6% In 44.1kHz - 10% Jitter 48 kHz Jitter 44.1kHz In/Out OK OK OK OK 4. AO8-IPC4, LED2 Test Please check [WordClock 75ohm SW]. Input Selector SW: WordClock 75ohm SW: 7segments LED: W.
AO8 ERROR MESSAGES If an error occurs in the connection to the DSP1D, or if the unit does not lock to the wordclock signal, one of the following error indications appears. ERROR MESSAGE DESCRIPTION The AO8 is connected to the INPUT connector of the DSP1D/DSP1D-EX. Connect the AO8 to the OUTPUT connector. A cable is disconnected from the INPUT A, B, or C connector on the rear panel, or the connection is made incorrectly. If the connection is proper, replace the cable.
