Baud Rate
9600 bps (standard)
(Switchable to 1200, 2400, 9600, 19200, 38400 bps)
Data Format
Start: 1-bit
Data: 8-bit
Parity: ODD
Stop: 1-bit
*Therefore, PC and PDP are connected with a straight cable.
Protocol
From computer to plasma display:
(1) When transmitting commands individually
STX (02 hex)+ ID (2 Byte)+ COMMAND (3 Byte)+ ETX (03 hex)
(2) When transmitting commands in batches (up to max. 3 commands).... (NOTE)
STX (02 hex)+ ID (2 Byte)+ COMMAND (3 Byte) +COMMAND (3 Byte) +COMMAND (3 Byte)+ ETX (03 hex)
(3) When transmitting direct numeric commands
STX (02 hex) ID (2 Byte) COMMAND (3 Byte) ARGUMENT (3 Byte) ETX (03 hex)
Note:
COMMAND 3 Bytes (ASCII)
ARGUMENT 3 Bytes (ASCII)
ID 2 bytes: It is ignored in this model. However, 2 bytes of character are required.
What has required waiting time is between commands.

List of RS-232C commands
When a command is received, there is action, such as being displayed. These commands have some which operate by input video
signal limitation.
*Mask color becomes effective at POWEROFF/ON.
- RS-232C adjustment validity:
Shows availability in RS-232C adjustment (service) mode. The AJY command is needed when using these commands.
- Normal validity:
Shows availability in normal operating mode. Valid commands can be used even if they do not follow the sending of the AJY
command.
- Factory adjustment validity:
Shows availability in Factory adjustment mode. As for this mode, it will be used only at the time of exchange of a circuit
board, and a fatal condition. The FAY command is needed when using these commands. Especially factory adjustment mode
should use it carefully. If usage is mistaken, trouble will appear in a product
- Numerical direct validity:
Shows commands that, if transmitted followed by 3-digit numbers, can directly set the adjustment value.
- Up/Down validity:
Shows whether or not a command, if transmitted followed by Upn/DWn (with n a number from 0 to 9), can or cannot increase
the adjusted value by that number alone.
X or Y: Valid blank_: Invalid
NOTE: X = Not put into last memory
