1. Overview
・ These specifications define projector control commands for PLC-ET30L.
・ The projector control commands are used to control a projector through RS-232C from a computer.

3. Notes for Communication
・ The projector command is defined as one command per line that starts with “C” and ends with
carriage return (0x0D).
・ When carriage return (0x0D) is received, decoding starts.
・ There are two types of commands; Functional Execution Commands which function in a way
comparable to remote and console keys and Status Read Commands which get basic statuses
of projector.
Example of Functional Execution Command: “C05” [CR]
Example of Status Read Command: “CR0” [CR]
・ In the cases below, it clears information of receive buffer.
1) When LF (0x0A) and EOF (0x1A) are received
2) When it takes more than a second to receive one command (until the projector receives
carriage return since it has received the first data)
・ or the pipelining of Functional Execution Command, allow the following interval time after
receiving return value.
1) Commands “VOLUME +/-“, “ZOOM UP/DOWN”, “FOCUS UP/DOWN” and “LENS-SHIFT
UP/DOWN/RIGHT” -->100ms
2) Other commands --> 500ms
・ For the pipelining of Status Read Command, allow more than 500 ms of interval time after
reception of return value.
・ Do not send any subsequent command before reception of return value; however this is not the
case when no response is returned after more than 5 seconds.
・ It takes about 7 seconds for internal initialization after plugging in AC power. During this time, it
cannot process commands. Do not issue any command.
・ During 7 seconds after powering on in Standby mode, when the command for internal
initialization or lamp lighting is received, ACK value is returned but the function is not executed.
However, for Status Read Command, the function is executed in 500 ms after receiving ACK
value for POWER ON command.
・ During countdown and cooling operations:
During countdown operation after execution of power-on, as well as during cooling operation after
execution of power-off, ACK value is returned but the function is not executed when command is
received.
・ On switching INPUT:
During 5 seconds after switching action has started in response to reception of INPUT switching
command, ACK value is returned but the function is not executed when command is received.
However, for Status Read Command, the function is executed in 500 ms after receiving ACK
value for INPUT switching command.
・ The number of characters indicating successful reception of command varies according to the
command. Please see [7. Status Read Command].
・ Characters used for commands must be Capital (A - Z).

6. Functional Execution Command
6.1 Format
・ PC issues a command in the following format:
“C” Command [CR]
Command: two characters (See Functional Execution Command Table)
・ Projector decodes the received data and returns the result when getting ready to receive the
next command.
[ACK] [CR]：(0x06, 0x0D) When received Functional Execution Commands.
・ When received data cannot be decoded, “?” [CR] is returned.
6.2 When the command pipelining is needed
In the case of the function requiring command pipelining, such as “Volume +/-“ and “Zoom +/-“,
operation should follow the same way as in remote control:
1) Sending-side system issues commands every 100 ms after receiving the return value.
2) When receiving an applicable command, the function is executed for 120 ms from the
moment.
3) When receiving the same command in sequence within 120 ms, the function is executed for
another 120 ms from the moment of the second command reception.
4) When any other command is not received after 120 ms, the execution of pipelining is stopped.
5) When Projector receives another command within 120 ms, the execution of pipelining is
stopped.
6.3 Transfer Example
