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.

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 Functional Execution Command

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.
