RS-232C Adjustment Mode
Through the unit’s RS-232C port, you can use a PC to make various
adjustments and settings.
About the RS-232C adjustment mode
1) Data Adjusted in RS-232C Adjustment Mode
• This data is written to the same memory area allocated for
Integrator mode.
2) Notes
(1) Adjustments are saved to last memory with the <AJN> command.
You must execute this command when adjustments are complete.
(2) Some RS-232C commands can be used in Normal operating
mode. Refer to “List of RS-232C Commands” in technical
manual for PDP-V402.
(3) If the conditions described in “Last Memory” are all met,
adjustment data and set items are stored in last memory, except
when:
• <IN 1-4> (input switching) is used in Normal operating mode.
• <AJY> (transition to RS-232C adjustment mode) is used
in Normal operating mode.
(4) About <DIN> (OSD displays disabled) and <DIY> (OSD
displays enabled)
Whether in <DIN> or <DIY> state, the following are shown:
• Menu screen
• “KEY LOCK” display
(5) The RS-232C adjustment mode is automatically released under
the following circuunsfances:
• The KEY LOCK/UNLOCK button is pressed.

(1) When transmitting commands individually
STX COMMAND ETX
STX=02h ETX=03h COMMAND 3-Byte (ASCII)
(2) When transmitting commands in batches
STX COMMAND COMMAND COMMAND ETX
Up to three commands can beissued simultaneously. Note)
(3) When transmitting direct numeric commands
STX COMMAND ARGUMENT ETX
ARGUMENT: 3-Byte(ASCII)
* D-sub 9Pin-D-sub 25Pin conversion cables
are now available on the market.
Interface
1) Connector D-sub 9 pins
2) Pin Assignment
3) Baud Rate
4800 bps (switchable to 1200, 2400, 9600, 19200 bps)
NOTE: Set the unit baud rate to match that of the PC in use. With
long RS-232C cables, we recommend using lower baud rates.
4) Data Format
Start: 1-bit
Data: 8-bit
Parity: 0 (no parity)
Stop:
1-bit
Error Example 1) STX PON AJY CNT ETX
Error Example 2) STX POF PON ETX
Error Example 3) STX IN2 AJY CNT ETX
Note)
Transmit PON and POF commands one by one. (Allow an interval
of three or more seconds between commands.)
Transmit an input switching command (IN 1-4) and <AJY>
command, allowing sufficient time between them. (Allow an interval
of approximately three or more seconds between input switching
commands (IN 1-4).)
Full-frame Output Procedure From a personal
computer:
AJY [Enter]
FMY [Enter]
When a personal computer is used, the setting is stored in memory
and not cleared until the same operation (AJY [Enter], FMY
[Enter]) is done next time.
