3 Notes for Communication
3.1 The projector command is defined one command/one line that starts “C” and ends carriage
return (0x0D).
3.2 There are two types of command, functional execution commands and state read commands.
Example of Functional Execution Command: “C05” [CR]
Example of State Read Command: “CR0” [CR]
When it takes more than one second to receive on command, it clears information of buffer.
(until the projector receives the carriage return since the projector has received the first
data.)
3.3 When control command pipelining, after the response, wait interval of time, 100ms, as
below.
More than 100ｍｓ
Command
PC →Projector “C”“0”“7”CRNextcommand
Projector →PC ACK CR
Response
( a few ms- 5s)
3.3.1 When a computer sends next command before receiving a return command, the
projector may not operate properly.
3.3.2 When there is no response after 5 seconds, issue next command.
3.4 It takes about 5 seconds for internal initialization after plugging in AC. During this time,
it cannot process command. Do not issue any commands.
3.5 Response for Status Read Command after accepting has different characters. See 7.
Status Read Command.
3.6 Characters for commands must be Capital (A - Z).

6 Functional Execution Command Table
6.1 Format
6.1.1 PC issues a command as below format
“C” COMMAND [CR]
Command: 2 characters (See Functional Execution Command Table)
6.1.2 A projector changes received data to decode and sends a return result after being
ready to receive next command.
[ACK] [CR]: (0x06、0x0D)When received functional execution commands.
6.1.3 “?” [CR]: When cannot read received data
6.2 When the command pipelining is needed
When some functions need command pipelining , the performance is the same as the remote
control’s performance.
1. System: issue any commands every 100ms after receiving response
2. When receiving the same command continuously with 120ms, the function is
executed for 120ms from that moment.
3. When receiving the same command continuously, with 120ms, the function
is executed for 120ms form the moment.
4. The next command is not issued after 120ms, and the execution is stopped.
5. If the projector receives other incoming commands within 120ms, the
execution is stopped.
