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. 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.

1. Install and set the above reference destination files.

2. At the very least, connect as shown in the figure above (when A08). If it is not possible to avoid making signal connections

other than these, turn off the power supply for all components other than those relevant to the write object and turn off the
control power supply for the volume of other components such as speakers and amplifiers. 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.

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.)

•PM1D inspection PC software preparation

Inspection with this device uses special PC software for inspection.
The software versions are as follows

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.

Connect the 5-pin PH connectors
with a straight-wired cable.

For the connection diagram, refer to the
LMY-slot inspection jig specifications.

Only COM1 can be used.

Before starting inspection, refer to version.txt in the same directory as the firmware shown on the previous page and input the
version character string as instructed. (Please refer to page 23, 24)

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.

* Turn on the power supply for AI8 before making the connection between the AI8 on the jig side and the jig for serial

communication. Warning: Do not connect until "" is displayed on the AI8 7-segment display.

* Use the LMY-slot inspection jigs inserted into the LMY-slots. For details, see the LMY-slot inspection jig

specifications.

* Serial communications jigs are boards that convert the serial interface from the PC. For details, see the LMY-slot

inspection jig specifications.

* Set the DIP switches on the ID change jig for AO8 inspection as shown below. For details on the IC change jig, see

the LMY-slot inspection jig specifications.

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
software are shown on the following pages.

3-1. AO8 - Slot [Initial] Test

Checks slot operation by checking the minimum necessary number of pins.

Stopped the moment an actual Addr.BusTest
or DataBusTest NG appears.

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)

Displays which pin
number is NG. The main
part of the address bus is
displayed. (1: NG; 0: OK)

First, all the voltages for one slot are
checked, then this is repeated for the
next slot. (The notation is each
voltage [x 8 slots], but the check
order is each slot [x all voltages].)

The detected voltage is displayed and the
percentage deviation from the ideal state
is displayed. This is shown for each slot.

Basically, the same as up till here

ERROR MESSAGES

AO8

27

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.

The unit does not lock to the wordclock signal.

The control signal is not being received correctly.

(two dots and the ID number of the OUTPUT connector on the DSP1D/DSP1D-EX)
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.

“ ” means that the control signal from the CS1D has changed the setting to “A”
“ ” means that the control signal from the CS1D has changed the setting to “B.”
During this time period, you can connect or disconnect the cable from the unselected output connector.
If you set the INPUT SELECTOR switch so that it matches the setting made via the control signal
from the CS1D, “ ” lights up continuously.

“. .”

“ .x.”
