							Panasonic  RS-232 Protocol    for LCD Projector 551 Introduction 
 
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.

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 
 
2.3 RS-232C Connection 
 
    Connector is Dsub 9pin (Female) as seen from the outside 
 
 
 
  
 Pin # Signal Comment 1  No connection 2 TXD  3 RXD  4  Connected Internally 5 GRD  6  No connection 7 CTS 8 RTS Connected Internally 9  No connection

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. 
 
  
  
						

							Panasonic  RS-232 Protocol    for LCD Projector 883 Communication 
 
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 
:  
[STX] I I S : V I D [ETX] 02 49 49 53 3A 56 49 44 03 Command with Parameter 
 
[STX] P O N [ETX] 02 50 4F 4E 03 Command without Parameter
