Notes for Communication
3.1
The projector 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 is not executed.
When it takes more than one second until the projector receives carriage return since it has
received the first data “C”, it clears the information of buffer.
3.4
When executing the command pipelining, wait the interval of 100ms after the response.
More than 100ms

CR
Response
(a few ms ∼ 5s)
When a command is issued before receiving the response, the function is not executed
properly. Except when there is no response for 5 seconds.
3.5
It takes about 5 seconds for internal initialization after plugging in AC power until it moves to
Standby mode. During this time, it cannot process commands. Do not issue any command.
3.6
The number of characters of the response to Status Read Commands depends on commands.
Please refer to [7. Status Read Command].
3.7
Characters for commands must be Capital (A - Z).

6.1
Format
6.1.1
PC issues a command in format as below:
“C” Command [CR]
Command: two characters (Refer to Functional Execution Command Table)
6.1.2
A projector changes the received data to decode and returns a result after being ready to
receive next command.
[ACK] [CR]: (0x06, 0x0D) When received Functional Execution Commands.
6.1.3
6.2
When the received data cannot be decoded, it returns “?” [CR]
Command Pipelining
When some functions (Volume +/-, Zoom +/-, etc.) need the command pipelining, the
performance is the same as that of the remote control.
6.2.1
System: issue any command every 100ms.
6.2.2
When receiving the appropriate command, the function is executed for 120ms from the
moment.
6.2.3
When receiving the same command continuously within 120ms, the function is executed for
another 120ms from the moment.
6.2.4
When there is no incoming command after 120ms, the execution of pipelining is stopped.
6.2.5
When the projector receives other incoming commands within 120ms, the execution of
pipelining is stopped.

When the status is Standby, Status Read Commands are always acceptable, but
Functional Execution Commands are not acceptable except POWER ON Command.
7.3.3
“40” [CR]

7.3.4
“20” [CR]
Status: Processing Cooling Down
When the status is Power ON, and POWER OFF Command (“C01” [CR]) is executed, it
moves to Cooling Down status.
This status automatically moves to Standby when the lamp is turned off and the fan spin
finishes after about 90 seconds.
This function is used to cool down lamps and other optical parts, and is quite important
for projector’s liability.
During this time, Functional Execution Commands are invalid.

7.3.5 “10” [CR]
Status: Power Failure
When the power supply voltage inside the projector reaches abnormal status, the status

The projector returns “10” [CR], which shows it moves to Power OFF status due to
power failure.
Fan also stops unlike Cooling Down status.
7.3.6
“28” [CR]
Status: Processing Cooling Down due to Abnormal Temperature
When the internal temperature increases abnormally, it automatically starts Cooling

8. Command with Address Specification
8.1
8.1.1
Overview
Commands with address are used to remote control multiple projectors through RS-232C by
one computer.
8.1.2
The command with address is defined as one command / one line that starts with ”A” and
ends with carriage return (0x0D).
8.1.3
When a projector receives carriage return (0x0D), it starts decoding.
8.1.4
This command is represented as Basic Command or Expand Command with address such
as “A001”. (The commands are the same when controlling one projector by one computer.)
(Ex) Functional Execution Command
“A001C05” [CR]
(Ex) Status Read Command
“A001CR0” [CR]
8.1.5
Projectors have the function to set up its address in Service Mode.
Initial setting is “No. 001”
Possible range is “001” to “999”
8.1.6
It clears the received buffer in this case as below:
࡮ When receiving LF (0x0A) or EOF (0x1A).
࡮ When it takes more than one second to receive one command.
(When it takes more than 1 second to receive carriage return since the projector has
received the first data.)
8.1.7
Wait the interval up to 60 ms for the response.

8.2
Functional Execution Command with address
8.2.1
Format
1)
PC issues a command in format as below:
“A” Address “C” Command [CR]
or
“C” Address “CFƑ” Command “Ƒ” Parameter [CR]
Address: 3-digit number (”001”-”999”)
Commands with “FFF” as the address are available for all projectors.
Command: Character line (Refer to Basic Commands or Expand Commands)
2)
The only projector with the appropriate address decodes the received command, and when
it is ready to receive next commands, it returns the response.
[ACK] [CR]: When receiving Functional Execution Command (0x06, 0x0D)
“?” [CR]: When the received data cannot be decoded
However, when address is “FFF”, it executes the function but does not return the response.
8.2.2
When the command pipelining is needed
When it needs the command pipelining, the operation is the same as the remote control.
1) System: PC issues commands every 100ms
2) When receiving the appropriate command, the projector executes it continuously for 120ms.
3) When receiving the same command within 120ms, the projector executes it continuously for
another 120ms from the moment.
4) When there is no command after 120ms, the execution of pipelining is stopped.
5) When receiving other incoming commands in 120ms, the execution of pipelining is stopped.

1) PC issues a command in format as below:
“A” Address “CR” Command [CR]
or
“A” Address “CRƑ” Command [CR]
Address: 3-digit number (“001”-“999”)
Command: Character line (Refer to Basic and Expand Serial Commands)
2) When the only projector with the appropriate address decodes the received command, and
returns the character line as the required data.
Required Data [CR]
Required Data: Character Line (Refer to Basic Status Read Command Table)
3) When the received data cannot to be decoded, it returns “?” [CR].
