2-4. Reading the Debug Display
"Debug Display" shows information of the mode controller on the
screen in dump list format.
The title is displayed at the left side of the screen at the second line,
while the data is displayed from the third to the ninth lines.
The display format of the data is basically 4 hexadecimal charac-
ters (2 bytes) equals one set, and one line is composed of up to four
sets (8 bytes).
When a certain key is pressed while the Fluorescent tube is off dur-
ing "Debug Display", the information to be displayed can be se-
lected.
The information currently defined is as follows.

2-4-1. [FRAME/TIME] Microprocessor Version
Displays the microprocessor version.
The third line displays the mode controller version, the fifth line
displays the VFD controller version, and the seventh line displays
the mechanism controller version.
According to the example in Fig. 9-2, the mode controller version
is "MMI-1151A 03/31A", the VFD controller version is "VFD-
1151A 02/17A", and the mechanism controller version is "MCM-
962B 9606 1962".

2-4-2. [1] Function Mode History
Displays the history of the function mode.
The function mode is the basic operation commands, such as STOP
and PLAY, which are transmitted from the mode controller to the
mechanism controller.
The function mode data is one byte each (hexadecimal 2 digits). 8
latest histories of the function mode can be stored at the one line,
and up to 24 histories in three lines.
The data is stored byte by byte from left to right. The data [FF] is
stored next to the last data stored. When the data reaches the right
edge of the first line, it is stored from the left edge of the second
line continuously. When it reaches the right edge of the third line, it
returns to the left edge of the first line again.
The current (stored last) function mode is the data at the left side of
the data [FF]. When this data [FF] is at the left edge of the first
(second, third) line, the function mode will be the data at the right
edge of the third (first, second) line.
The data [FE] indicates that an emergency has occurred there. To
find out the type of emergency, refer to "2-4-3. Emergency His-
tory".
