1 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 i s assumed for its use.

2 Connection

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

3 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

3.2 Replies

When commands are sent to projector, the projector will respond in the following manner.

1) Normal command receiving
When the command is in the proper format and correct communications has been established
between the controlling dev ice and the projector, the projector will reply with the response
information.

2) Command receiving error (NO Response)

If no response is transmitted from the projector, then check the communication settings and the
cable configuration. The command string must start with a [STX] Start of Text message. This
will alert the projector to start receiving commands. An [ETX] End of Text message must end
the command string or the projector will not execute the command.

3) Command Receiving Error [STX]ER401[ETX]

If this error is transmitted from the projector, the projector did not recognize the command that
was sent from the control device. Check the command list to ensure that the command is valid,
and the characters are capitalized.

4) Command Receiving Error [STX]ER402[ETX

If this command is transmitted from the projector, the projector did not recognize the parameter
that was sent from the control device. Check the command list for the appropriate parameter
data that is to be sent with the appropriate command to the projector.

5) Query Reponses

If a command such as [STX]Q$L[ETX] Query Lamp Operation Time is sent. The projector will
send the reply of [STX]Q$L:0000[ETX]. Parameter information will be replied only in the case of
a Question type command. Check the command list for the specific information.
