1. Overview
1.1. These specifications define projector control commands for LC-XG300/250 (1.0” XGAⅢ).
1.2. The projector control commands are used to remotely control a projector through RS-232C from a
computer.
2. Serial Interface Specifications
2.1. Transfer Specifications

3. Notes for Communication
3.1. The projector control command is defined as one command/one line that starts with “C” and ends
with carriage return (0x0D).
3.2. When the projector receives carriage return (0x0D), decoding starts.
3.3. There are two types of Commands: Functional Execution Commands, which execute the same
function as the projector keys and remote control, and Status Read Commands, which get the basic
status of the projector.
Example of Functional Execution Command: “C05” [CR]
Example of Status Read Command: “CR0” [CR]
3.4. It clears the information of buffer in the cases below.
3.4.1. When the projector receives LF (0x0A) or EOF (0x1A)
3.4.2. When it takes more than one second to receive one command (until the projector receives
carriage return since it has received the first data)
3.5. For the pipelining of Functional Execution Command, wait for the following interval time after
receiving a response.
3.5.1. Commands “VOLUME+/-“, “ZOOM UP/DOWN”, “FOCUS UP/DOWN” and “LENS-SHIFT
UP/DOWN/LEFT/RIGHT” →100ms
3.5.2. Other Commands →500ms
3.6. For the pipelining of Status Read Command, wait for the interval time of 500ms at least after
receiving a response.
3.7. When a command is issued before receiving a response, the function is not executed properly
except when there is no Response for more than 5 seconds.
3.8. 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.
3.9. Internal initialization and lamp lighting is executed during 7 seconds after powering on in Standby
mode. When the command is sent during this time, ACK value is returned but the function is not
executed. However, Status Read Command is executed 500ms after receiving ACK value for Power
ON command.
3.10. During countdown and cooling down:
When the command is received during countdown after Power ON and cooling down after Power
OFF, ACK value is returned but the function is not executed. However, Status Read Command
can be executed.
3.11. 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 500ms after receiving ACK value
for INPUT switching command.
3.12. The number of characters of response to Status Read Commands depends on commands.
Please see [7. Status Read Commands].

3.13. Characters for commands must be Capital (A - Z).

6. Functional Execution Command
6.1. Format
6.5.1. PC issues a command in format as below.
“C” COMMAND [CR]
Command: two characters (See Basic Functional Execution Command Table)
6.5.2. A projector changes received data to decode and returns a result after being ready to receive
next command.
[ACK]［CR］：（0x06、0x0D）When received Functional Execution Commands.
6.5.3. “？”［CR］：When the received data cannot be decoded.
6.2. Command Pipelining
When some functions need the command pipelining (Volume +/-, Zoom +/-, etc), the performance is
the same as that of the remote control;
6.2.1. System: issue any command every 100 ms.
6.2.2. When receiving the appropriate command, the function is executed for 120 ms from the
moment.
6.2.3. When receiving the same command continuously within 120 ms, the function is executed for
another 120 ms from the moment.
6.2.4. When there is no incoming command after 120 ms, the execution of pipelining is stopped.
6.2.5. When the projector receives other incoming commands within 120ms, the execution of
pipelining is stopped.
6.3. Transfer Example
Switch the projector to video mode with Basic Command.
