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.

2-2 Loading the Firmware
The firmware used must be the “AI8/AO8 Firmware” (managed with the already drawn CD-R assembly drawing (3JL-XY714A0)) of the PM1D System Software with a version later than the version shown on the cover.
For details on the firmware writing method, refer to theTest Program Specifications KES-92652.

Inspection
3-1.
Inspection with Test Program
· Inspect based on the Test Program Specifications KES-92653.
3-2.
Jitter Measurement
· Connect the LMY-slot inspection jig Canon terminal to DSA1.
· Set Fs to 48 kHz and 44.1 kHz with the test program and measure the jitter at DSA1.
TEL 13942296513

Firmware Load Test
Check that it is possible to load the firmware as in 2-2. using the Input B terminal.
3-6.
Inspects word clock output of INPUT A, B
In the test program performed in 3-1, use the oscilloscope to monitor Pin 5 of IC101 of sheet IPC for output A of A18 that is being used as a jig using the timing shown below. Confirm that 44.1 kHz word clock is being output.
(It is good if the wave form like the one shown in Figure 1 appears.)

TEST PROGRAM
QQ 376315150 8 9 2 4 9 8 2 9 9
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. There are two methods for writing this firmware: to write it indirectly using the CS1D or DSP1D RS232C port or to write it directly to the AO8 UNC sheet. The detailed methods are given below.
• Method for writing firmware using the DSP1D RS232C port
* It is possible to write the AO8 (UNC) firmware from the PC via the CS1D or DSP1D RS232C port. This is the method normally used.
Software used: PM1DLOAD within PM1D system software
Firmware used: AI8/AO8 firmware in PM1D system software
Version used: PM1DLOAD and the AI8/AO8 firmware are files composed using a PM1D SYSTEM SOFTWARE with a version later than the version shown on the cover.
(Managed with the already drawn CD-R assembly drawing (3JL-XY714A0).)
* For the installation and setting methods, refer to the CS1D Test Program Specifications.

Please note that at that time, if other
AI8/A08 are connected they may be written and because of this, there is no guaranteed that the writing has been properly performed even if the writing shows a successful completion.
3. Use the methods shown in the CS1D Test Program Specifications to write the firmware to the necessary units.
After the firmware has been written, check that the versions for all the units are the desired versions.
• Method for writing firmware directly to the AO8 UNC
* When there is some kind of problem or the DSP1D is unavailable due to this equipment's production processes and the firmware can not be written with the method on the previous page, use the method below.

Connect the 5-pin PH connectors with a straight-wired cable.
1. Connect the D-sub 9-pin serial cables (cross) and DSP-CHECK board between the 5-pin connector for the target board and the
PC. At this time, do not connect other signal lines.
2. After PM1DLOAD starts up, select CardDirect with MODE SELECT, then press OK.
3. Use the setup menu to properly set the serial port to be used and then select AI8/A08 from the pull-down menu.
4. Check on the items for OUTPUT 1 on the list and click the write button.
5. After writing ends, end PM1DLOAD.
6. Switch off the power for AO8 and remove the PH connector, then switch the power for AO8. DSP1D on again and check that it starts up normally. (Operation is normal if an " " is displayed in 7-segment display for A08.) www. xiaoyu163. com

B. Inspection Method
The inspection configuration is shown in the diagram below.
Install the inspection jig to the AO8 to be inspected as in the figure above. Send the inspection commands from the PC via the AI8 to the
LMY-slot inspection jig and take in at the PC the results returned from the LMY-slot inspection jig.

The AO8 is inspected using PC inspection software. This inspection software is common for AI8/AO8/DSP1D/CS1D. For the basic operation methods, menu screen specifications, etc., see the CS1D Test Program Specifications.
Below is the menu for AO8 inspection.
Input the latest version of AO8 UNC before starting the inspection. (This is necessary for the version check.) For the character string to input, refer to version.txt in the same directory as the AI8/AO8 firmware. Details of each check item and the corresponding PC www. xiaoyu163. com http://www.xiaoyu163.com

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.
The unit does not lock to the wordclock signal.
The control signal is not being received correctly.

Illuminating dots means that the AO8 is con-nected in Mirror mode from the DSP1D/DSP1D-EX.
If “.x .” lights up continuously during Mirror mode operation, the INPUT SELECTOR switch setting matches the setting controlled from the CS1D and the system is operating normally.
If the control signal from the CS1D has changed the setting during Mirror mode operation and it does not match the INPUT SELECTOR switch setting any more, this indicator changes in the following order.
