This Diag Program consists of a number of Diag. programs for the
UP-600/700, which facilitate the PWB check, process check and the
operation check of the system during servicing.

The Service Diag. programs are all contained in the standard ROM.

UP-25X main only

The Diag. Program is written on the external ROM, which is executed
by the CPU (H8/510) and it runs on the following conditions:

The logic power supply is normal.
(+5V, VCKDC, POFF, +24V)

Both the I/O pins of the CPU and the CPU internal logic are
normal, and the CKDC9 and MPCA9, system bus, and standard
ROM/RAM are normal.

When starting the SET for the first time, MASTER RESET the sys-
tem. If you want to add any OPTION UNIT when the SET is operating
normally, perform PROGRAM RESET.

To start the Diag. Program, enter the SRV mode. Select the option
item DIAGNOSTICS from the MENU using the cursor keys and press
the ENTER key.

The DIAG. MAIN MENU appears on screen as given below. The
cursor shown in reverse video can be moved using the up/down
arrow keys. Move the cursor to the menu item you want and press
ENTER to execute the corresponding Diag. program. When each
Diag. program is completed, the screen returns to the DIAG. MAIN
MENU. Pres the CANCEL key to exit the Diag. Program and the
screen returns to the MENU screen in the SRV mode.

The cursor moves along through the menu items by entering num-
bers with the numeric keypad. This allows you to reduce the number
of key operations. (Example: By entering the number 7, the cursor
moves to the menu item TCP/IP.) This method also applies to other

SUB MENUs.

The menu item "EFT Diagnostics" are availalable only for the Euro-
pean market. For North America,

the this menu item (&EFT) is omitted and everything the following it
moves up to compensate.

This program tests the standard RAM, expanded RAM, standard and
service ROMs, and SSp circuit. RAM&ROM&SSP is selected on the
MAIN MENU, the following submenu screen appears. The cursor
shown in reverse video can be moved using the up/down arrow keys.
Move the cursor to the menu item you want and press the ENTER to
execute the corresponding program. Press the CANCEL key to return
the screen to this submenu.

Checking

The program performs the following checks on the standard
512KB of RAM. Data in memory remains unchanged before and
after the checks.

The following operations are performed for the memory addresses
to be checked (780000H - 7FFFFFH).

PASS1 : Save data in memory

PASS2 : Write data "0000H"

PASS3 : Read and compare data "0000H" and write data "5555H".

PASS4 : Read and compare data "5555H" and write data "AAAAH"

PASS5 : Read and compare data "AAAAH"

PASS6 : Return data into memory

If any comparison is not normal during the check sequence from
PASS 1 through 6, the error message appears.

If any error is not found up to the final address, the sequence
ends normally.

Then, another round of address checks is carried out using the
above check sequence

If an error occurs, the error message appears and the check
stops. The read/write of the address where the error occurs is
repeated.

Check point address = 780000H, 780001H

Checking

The standard ROM area (200000H - 3FFFFFH) is added in units
of bytes. The lowest 2 digits of the result is 20H, it is regarded as
normal. 

In addition, the ROM version and model name code stored in the
addresses 31FFE0H - 31FFFFH where the ROM version and
checksum correction data are stored are displayed. Data (ASCII)
is stored in the following formats: 

31FFE0H~31FFEFH : Model name CODE (Example: "UP-600",

to be displayed until DATA becomes 00H.)

31FFF0H~31FFF9H : 27801R****(****=PROGRAM VERSION)

31FFFAH~31FFFBH : BLOCK NO.("20"~"3F")

31FFFCH : TERMINATOR ("=")

31FFFDH~31FFFEH : BLOCK VERSION (Example: "00")

31FFFFH : CHECK SUM correction DATA

FLASH ROM used as the standard ROM has 64K-byte-unit re-
write BLOCKs. To perform VERSION management in the BLOCK
unit, these BLOCKs have the same 16 byte organization as those
after the previous 31FFF0H and arranged every 64KBYTE. At this
time, the checksum for each BLOCK is corrected to be 01H so
that the entire 2MBYTE become a total of 20H.

Regarding the display of the PROGRAM VERSION, the FLASH
write MASTER EPROM has 2-chip 8 Mbits to allow manage in
units of chip. The PROGRAM VERSION stored in blocks at 21H
and 31H are displayed.

0 PAGE (BLOCK) where IPL is stored displays the PROGRAM
VERSION of IPL to make it possible to manage individual pro-
grams.

The program tests the RS232 interface for the main PWB and the
optional board ER-A5RS. Attach a 9-pin D-sub loop back connector
(UKOG-6717RCZZ) wired as shown in Fig. 3-11, to the port you are
going to test.

Fig. 3-11. Wiring diagram of loop back connector (UKOG-6717RCZZ)

The following menu appears on screen. The cursor shown in reverse
video can be moved using the up/down arrow keys. Move the cursor
to the menu item you want to execute and select by pressing the
Enter key to the corresponding Diag. Program. Press the CANCEL
key to return the screen to this submenu.

When setting the channel for the RS232 interface, do not set more
than two ports to the same channel. The UP-600/700 accommodates
up to one ER-A5RS board, but use caution not to allow each port to
have the same channel; otherwise hardware might be destroyed.

When Diag. Is started, channel check is performed and only the
channels already set appear on screen.

Checking

The screen shows only the channels for which the channels of the
RS232 connect to the ECR. Compare the channels shown on
screen and the settings of channel setting DIPSW on the RS232
interface board. 

The RS232 on the main PWB of the UP-600/700 is fixed to CH1
and CH8. It is therefore necessary for the ER-A5RS to set the
channel to any of CH2 - CH7.
