1Introduction
This document describes the commands and data formats to control by RS-232C,
from a controller to the Panasonic projector.
This document should be used in conjunction with the Operation Instructions.
Information furnished in this document, is believed to be accurate and reliable.
However, no responsibility is assumed for its use.

2Connection
2.1 Communication Parameters
Signal Level RS-232C
Sync Method Asynchronous
Data Speed 9600 bps
Data length 8bit
Parity None
Stop bit 1
X Parameter None
S Parameter None
Code (command) JIS X 0201 (Capital Letters Only)
The device controlling the projector must match the above parameters. There is no capability to
change the settings of the projector.
2.2 Address level
The address level of this Projector corresponds to address level 0 within the MIS standard. This unit
does not support multiple machine control from a single communication port.
Address level 0 only one projector and the address information is eliminated

2.4 Cable Specifications
Use a RS-232C 9 pin to 9 pin straight cable. Pins 4,7 and 8 are internally shorted together in the
projector.

3Communication
3.1 Command Format
Implement commands that are to be sent to the projector in the following manner.
[STX] COM1:P1P2P3P4 [ETX]
Head identifier -Send [STX] (Hex’02’or Ctrl B for ASCII), at the beginning of the command string.
This will allow the projector to receive the following command.
Command (COM1) –The Command is written by 3 characters. The Letters are capitalized. . See
the command tables in Section 5 for details.
Parameter (P1P2P3P4) -The Parameter data is required by certain commands. The parameter
data information can be 1 to 4 bytes in length, which is dependant on the individual commands. If no
parameter is required by the specific command, then this information does not need to be
transmitted. See the command tables in Section 5 for details.
End identifier -Send [ETX] (Hex’03’or CTRL C for ASCII) at the end of command string.
Command and its parameter should be separated by a ”:” colon (Hex’3A’). When a command that
does not require parameters is sent, then the separating colon can be eliminated.
Example of a command string
