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.There are two types of Commands: Functional Execution Commands and Status Read
Commands.
Example of Functional Execution Command: “C05” [CR]
Example of Status Read Command: “CR0” [CR]
３.３.When it takes more than one second to receive one command, it does not operate.
The information of buffer is cleared when it takes more than one second to receive carriage return
(0x0D) after the projector receives the first data “C”.
３.４.For Command pipelining, wait for the interval of 100ms after receiving a response.
More than 100ms
Command
PC →Projector “C” “0” “7” CR Next Command
Projector →PC ACK CR
Response
(A few ms 〜5s)
3.4.1. When a command is issued before receiving a response, the function is not executed
properly.
3.4.2. Except for when there is no Response for more than 5 seconds.
３.５.It takes about 5 seconds for internal initialization after plugging in AC power. During this time, it
cannot process commands. Do not issue any command.
３.６.The number of characters of response to Status Read Commands depends on commands.
Please see [7. Status Read Commands].
３.７.Characters for commands must be Capital (A - Z).

６．Functional Execution Command
6.1. Format
6.1.1PC issues a command in format as below.
“C” COMMAND [CR]
Command: two characters (See Basic Functional Execution Command Table)
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.
6.1.2“？”［CR］：When the received data cannot be decoded.
6.2. Command Pipelining
When some functions need the command pipelining, the performance is the same as that of the
remote control;
6.2.1. System: issues 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.
