3. Notes for Communication
1. The projector control command is defined as one command/one line that starts with “C” and ends
with carriage return (0x0D).
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. 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”.
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)
4.1. When a command is issued before receiving a response, the function is not executed properly.
4.2. Except for when there is no Response for more than 5 seconds.
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.
6. The number of characters of response to Status Read Commands depends on commands.
Please see [7. Status Read Commands].
7. Characters for commands must be Capital (A- Z).
