4. Notes for Communication
4.1. The projector command is defined one command/one line that starts “ C” and ends carriage
return (0x0D).
4.2. The projector starts decoding after the carriage return.
4.3. 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]
4.4. It clears information of accepting buffer as following terms.
1. When a projector receives LF (0xoA) or EOF (0x1A)
2. When it takes more than one second to receive on e command
(Until the projector receives the carriage return after the projector receives the first data)
4.5. When control command pipelining, after the response, wait interval of time as below.
1. COMMAND such as ”VOLUME +/-“! 100ms
2. Other COMMAND! 500ms
4.6. Wait at least 500 ms after the response, when status read command pipelining.
4.7. Do not issue any command before the Response.
When there is no response after 5 seconds, issue next command.
4.8. It takes about 7 seconds for internal initialization after plugging in AC. During this time, it
cannot process command. Do not issue any commands.
4.9. 7 seconds after Power ON from Standby, even when a projector receives a command, a
computer receives acceptable response, but it does not execute for internal initialization and
lamp lighting process. However, Status Read Commands are executed after 500ms when
they receive acceptable response.
4.10. About performance during processing count down or cooling down.
When a projector receives After Stand By or Power ON, Even when a projector receives a
command, a computer receives response to accept the command, but it does not execute
for internal initialization and lamp lighting process. However, Status Read Commands
are executed.
4.11. About performance when changing INPUT.
After receiving INPUT switching command, when receiving commands between 5 seconds
from starting the switching to completing the switching, a computer receives acceptable
command, but it is not executed.
However, status read commands are executed after a computer receives response to
accept the command, after 500ms.
4.12. Response for Status Read Command after accepting has different characters.
See ”Status Read Command Table”.
4.13. Characters for commands must be Capital (A - Z).

7. Functional Execution Command
7.1. Format
1. PC issues a command as below form at
“C” COMMAND [CR]
COMMAND: 2 characters (See Functional Execution Command Table)
2. A projector decodes received data and sends a return result after being ready to
receive next command.
[ACK] [CR]: (0x06, 0x0D) When received functional execution commands.
“?” [CR]: When cannot read received data.
7.2. 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 any relevant command, the function is executed continuously for
120ms.
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.
7.3. Transfer Example

Detail Get the projector status.
Acceptable “%1” [CR]
%1
“00” = Power ON
“80” = Standby
“40” = Processing Count Down
“20” = Processing Cooling Down
“10” = Power Failure
“28” = Processing cooling down due to abnormal temperature
“08” = Abnormal Temperature
“88” = Normal after recovering abnormal temperature
“02” = Cannot accept RS232C command
“24” = Processing Cooling Down for Power Save

SERIAL FUNCTIONAL SPECIFICATION
8.3.2. “80” [CR]
Status: Standby
When the status is Standby, Status Read Commands are always acceptable, but
Functional Execution Commands are not acceptable except Power ON Command.
8.3.3. “40” [CR]
Status: Processing Count down
When “Display” in Setting Menu is ON and Power ON is executed, it starts
processing Count Down.
When “Display” OFF in the setting menu is set, processing Count Down is skipped
and the status moves to Power ON quickly.
8.3.4. “20” [CR]
Status: Processing Cooling
When status is Power ON, and Power OFF Command is executed, it moves to
cooling status.
This cooling status automatically moves on to Standby after the lamp turns off and
the fan spin for about 90seconds.
This cooling down works for lamps and other optical accessories.
Control commands are not available for this status.
8.3.5. “10” [CR]
Status: Abnormal power
When the power supply voltage inside the projector reaches abnormal, the power
will be automatically turned off. The projector returns “10” [CR] and cooling fan is
also stopped at the time.
8.3.6. “28” [CR]
Status: Processing Cooling Down by abn ormal temperature
When the temperature inside a projector is out of the operating temperature, it
automatically starts cooling down. Response is “28” [CR].
Even if the temperature is processing low, the cooling down is executed.
8.3.7. “08” [CR]
Status: Abnormal temperature
When the temperature does not go down after cooling down due to the abnormal
temperature, this is the Response. The projector keeps the Standby status.
8.3.8. “88” [CR]
Status: Normal status after recovering abnormal temperature
When the temperature goes down after cooling down and moving to Standby status,
this is the response.
