Flash ROM check (for graphic data)
1. In order to prevent the Flash ROM (4M) equipped models
to be installed with the Mask ROM (2M) panel, and to pre-
vent the Mask ROM (2M) equipped models to be installed
with the Flash ROM (4M) panels, with the STANDBY
sources during the test mode, the following display will be
made according to the system
µ
-com and panel combina-
tion.
• Flash ROM (4M) equipped model and Flash ROM (4M) panel
All lights turned on – – – OK!
• Mask ROM (2M) equipped model and Mask ROM (2M) panel
All lights turned on – – – OK!
• Flash ROM (4M) equipped model and Mask ROM (2M) panel
“M4P2” – – – NG!
• Mask ROM (2M) equipped model and Flash ROM (4M) panel
“M2P4” – – – NG!
∗
Flash ROM (4M) : DPX-U099 (X16 IC1)
Mask ROM (2M) : DPX701/701U/701UY/DPX-MP7090U
(X16 IC1)
2. When entering the test mode, the manufacture code of the
Flash ROM (4M) is read and when it is normal, FROMCHK
of the 100th terminal (Panel
µ
-com) repeats Hi
→
Low
→
Hi · · ·. If the reading is abnormal, “Low” is output.
If the manufacture code is normal, by pressing [AM] key for
less than 1 second, the connection checks on all terminal
is started. If the connections are normal, the FROMCHK
terminal stops the Hi
→
Low
→
Hi · · · repeating and out-
puts “Hi”. If the reading is abnormal, “Low” is output.
3. If the [AM] key is pressed for 2 seconds while all lights are
on, Flash ROM (4M) data is initialized.
While the deletion is executed, “Data_Erase....” is displayed.
Note : Do not touch any key white this is in progress.
When erasing is complete, “Erase_OK!!” is displayed.
If “Erase_NG!!!!!!” is displayed, it was not possible to erase
the data on the Flash ROM (4M).
In this case, pressing [AM] key for at least 1 second again.
If it is the same, then there is an abnormality with the Flash
ROM.
