3. Notes for Communications
3.1 The projector command is defined one command/one line that starts “C” and
ends carriage return (0x0D).
3.2 When a projector receives carriage return (0x0D), it starts decoding.
3.3 There are two type commands, functional execution commands and state read
commands. Functional execution commands works as a remote control and key on
the projector, and State read command works to know the projector status.
Example of Functional Execution Command ：”C05” [CR]
Example of State Read Command ：”CR0” [CR]
3.4 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.)
3.5 When control command pipelining, after the response, wait interval of time as below.
3.5.1 “VOLUME +/-“ ”ZOOM UP/DOW””FOCUS UP/DOWN” ”LENS-SHIF
UP/DOWN/LEFT/RIGHT” Commands →100ms
3.5.2 Other Commands →500 ms
3.6 Wait at least 500ms after the response, when status read command pipelining.
3.7 Do not issue command before the Response in the situation as below, except no
response after 5 seconds.
3.8 It takes about 7 seconds for internal initialization after plugging in AC. During this
time, it cannot process command. Do not issue any commands.
3.9 7 seconds after Stand By or Power ON, 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.
3.10 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 after 500ms when a computer receives
acceptable response.
3.11 When a projector receives a command while processing count down after Power ON
or cooling down after Power Off, a computer receives response to accept the
command but the command is not executed.
However, Status Read Commands are executed.

Page 7 / 24
3.12 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. Response command characters for status read
success are different. See “7, State Read Command” for the details.
3.13 Command are shown in a capital letter (A 〜Z). Lower case letters are not
available.

４.1 Format
１.PC issues a command as below format.
“Ｃ” Command [CR]
Command：2 characters（See Functional Execution Command Table）
２.A projector changes received data to decode and send a return result after
being ready to receive next command.
[ACK]［CR］：（0x06、0x0D）When a projector receives a functional execution
command.
“？”［CR］：When cannot read receiving data
４.2 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 command every 100ms
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 from that moment.
４.After 120ms, the next command is not issued, the execution is stopped.
５.If the projector receives other incoming commands within 120ms, the
execution is stopped.
