STARTING MEDIA (FD)
Before executing the Diagnostic program, you must create the MS-DOS
starting media and copy the Diagnostics program onto it.
starting media and copy the Diagnostics program onto it.
HOW TO CREATE AN MS-DOS STARTING MEDIA
1) Execute the command given below on the PC where the MS-
DOS Ver. 6.22 is running and create an MS-DOS starting
media (FD).
MS-DOS (Command) format a: /s
2) Copy the Diagnostics program onto the MS-DOS starting media
(FD).
1. GENERAL
This diagnostic program is used to check the PWB’s, the process, and
the machine of the UP-5900 series in a simplified manner.
This test program is supplied with floppy disks.
2. SYSTEM CONFIGURATION
The system requires the POS terminal, and a PS2 keyboard for diag-
nostic operations.

3. SERVICE DIAGNOSTICS
3-1. SERVICE DIAGNOSTICS GETTING STARTED
GETTING STARTED:
Execute “SRV.BAT” by entering the command with the PS2 keyboard
as follows:
as follows:
A:\> SRV
b
“A:\>” is the DOS prompt. (Used by the FD)
*
Do not load any device drivers when using this program.
*
To operate other applications after performing this program, it is rec-
ommended to re-boot the machine.
3-2. SELECTION MENU
The diagnostics menu is started and the following menu is displayed.
The highlighted cursor is moved by the cursor keys (UP
2
and
DOWN
4
) of the PS2 keyboard. Move the cursor to the desired item,
and press the Enter key to execute the selected diagnostics program.
When the selected diagnostics program is completed, the display
returns to the menu screen by pressing the ESC key. Select “Diagnos-
returns to the menu screen by pressing the ESC key. Select “Diagnos-
tics End” and press the Enter key to terminate the diagnostics.
3-3. RAM DIAGNOSTICS
This program is used to test the standard memory and the extension
memory.
1) D-RAM CHECK
1
Checking content
All memory areas are checked in blocks of 512KB. The checking
procedures are as follows:
procedures are as follows:
i.
Test data 5555H is written to all the test areas.
ii.
Test data and read data are compared by each word, If it is
O.K., test data AAAAH is written to the test area.
iii. Test data and read data are compared by each word, If it is
O.K., test data 5555H is written to the test area.
iv. Test data 0000H is written to all the test areas.
v.
Test data and read data are compared by each word, If it is
O.K., test data FFFFH is written to the test area.
vi. Test data and read data are compared by each word, If it is
O.K., test data 0000H is written to the test area.
When an error occurs during the test, the error address and data are
displayed and the test is stopped.
For the extended memory test, the value is set in the setup of the
read test and is made to the area in increments of 512KB.
2
Display
The error address and the error data are displayed only when an
error occurs. (When no errors occur, they are not displayed.)

up. The checking procedure is as follows:
up. The checking procedure is as follows:
i.
Test address data is saved to the main memory.
ii.
Test data 55H is written to the test address.
iii. Test data and read data are compared, and test data AAH is
written to the test address.
iv. Test data and read data are compared.
v.
The saved test data is written to the test area.
vi. The address is incremented until it becomes 3FH.
If POFF interruption is generated during the test, the test is stopped
and the saved data is written to the test area within 50ms.

The initial display is as follows:
1) CONTROLLER DIAGNOSTICS TEST
1
Checking content
After initializing the controller, the diagnostic command is executed.
The procedures are as follows:
• One byte of sample data (FFh) is sent and a wait state of 100ms
is made.
• The reset command (80h) is sent and a wait state for the end
code (2 bytes: 90h and 00h) from the controller is made.
• The diagnostic command (2 bytes: 89h, any one-byte data) is
executed, and a wait state for the end code (3 bytes: 90h, return
code, any one-byte data) is made.
• If an error occurs the error display is made with the return code.
*
To exit from the controller diagnostic test, press the Esc key dur-
ing the wait state for the end code response.
