AI8 INSPECTION 1. Range of Applicability These specifications apply to the AI8, AI8-ML8, AI8-AD8, and AI8-ML4AD4. 2. Preparations 2-1. Conditions For details on the connection method, refer to the Test Program Specifications KES-92652. Unless otherwise specified, the conditions are as follows. · Set the PHANTOM MASTER switch to On. · Set WORD CLOCK IN 75 Ω to ON. · Set the CONTROL INPUT PORT to A.
AI8 (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 input terminals and verify that there is no noise. However, for the LMY2-ML, only the A terminal needs to be checked. (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 input terminals and verify that there is no noise. However, for the LMY2-ML, only the A terminal needs to be checked. 3-5. 4.
AI8 TEST PROGRAM A. Preparations for Inspection • Writing the firmware This equipment requires firmware. When there are changes to the program for this equipment and during manufacturing processes, 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.
AI8 Software used: Version used: Method of preparation: 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).) Follow the instructions in the CS1D test program specifications (Drawing No: KES-92654) titled "Procedure for extracting software groups for production and customer service applications". Once the files have been extracted, refer to the Readme.
AI8 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 AI8 - UNC test AI8 - IFC2 test AI8 - SLOT test AI8 - IPC3, LED1 test AI8 - IPC1 test AI8 - UNC Test This test checks around the AI8-UNC. OK/NG display for the page as a whole Displayed when all the checks have been completed. 1.
AI8 3-1. AI8 - 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.
AI8 4. AI8 - IPC3, LED1 test This test checks around the AI8 - IPC3 and LED1. 4. AI8-IPC3, LED1 Test For the 75 switch item, the pop-up box is displayed below and the inspector judges visually on the oscilloscope. OK * Control Input Port SW * W.CLK 75ohm SW * Phantom Master SW * 7segments LED * W.CLK In 48 kHz + 6% In 44.1kHz - 10% Jitter 48 kHz Jitter 44.1kHz DIR2 In/Out OK OK OK OK OK 4. AI8-IPC3, LED1 Test Please check [WordClock 75ohm SW].
AI8 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 AI8 is connected to the OUTPUT connector of the DSP1D/DSP1D-EX. Connect the AI8 to the INPUT connector. A cable is disconnected from the OUTPUT A, B, or C connector on the rear panel, or the connection is made incorrectly. If the connection is proper, replace the cable.
