Frequently Asked Questions - LV-7292M CANON

How to turn on the projector remotely?

Use the serial command C00 followed by a carriage return (CR) to turn on the projector. Make sure the RS-232C connection is correct.

How to quickly turn off the projector?

The command C01 (Quick Power OFF) turns off immediately without confirmation. Use C02 for normal shutdown with confirmation display.

What image modes are available?

The modes include Standard, High Contrast, Cinema, Presentation, Blackboard (green), Colorboard, and four user profiles (User 1 to 4). Activate them via serial commands C11 to C18, C39, etc.

How to select the HDMI input?

Send the command C04 to switch to HDMI input. Note that the automatic input search (Auto Input) does not activate with this command if set to On1 or On2.

How to correct keystone distortion?

Use commands C8E (Keystone ↑) to reduce the top part and C8F (Keystone ↓) to reduce the bottom part. These corrections are temporary.

How to read the lamp usage time?

Send command CR3 (Lamp Time Read). The response is a 5-digit code indicating hours (e.g., 00410 = 410 hours).

What to do if the projector no longer responds to commands?

Check the RS-232C connection (dedicated cable), the baud rate settings (9600 or 19200), and ensure the projector is not in Eco mode or cooling down. Wait 5 seconds after power-on.

How to clean the projector's air filter?

Turn off the projector and unplug it. Open the filter panel, remove the filter, clean it with a vacuum or warm water, dry it completely before reinstalling. Replace it every 1000 hours of use.

Can I use a universal remote control?

This projector uses specific RS-232C serial commands. A standard infrared remote is not compatible; you must use an external control system (PC, PLC) with the commands listed in the manual.

How to activate the Presentation Timer mode?

Send command C8A to start the presentation timer, and C8B to exit the timer menu. This works like the P-TIMER button on the remote control.

1.2. The projector control commands are used to remotely control a projector through RS-232C from a computer.

Serial Interface Specifications

2.1. Transfer Specifications

Item	Specifications
Synchronous system	Asynchronous
Transmission Speed	9600 / 19200
Data Length	8 bit
Parity	N/A
Stop Bit	1
Flow Control	N/A

1) Transmission speed: initial setting value is 19200.
2) Transmission speed can be changed in service mode.

2.2. Connection

Dedicated serial cable must be used for connection to a computer and a projector.

Dedicated serial cable must be used for connection to a computer and a projector.

Notes for Communication

. . The projector control command is defined as one command/one line that starts with "C" and ends with carriage return (0xD).
. . 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]

. . When it takes more than one second to receive one command, it does not operate.

The information of buffer is cleared when it takes more than one second to receive carriage return (0xD) after the projector receives the first data "C".

. . For Command pipelining, wait for the interval of 100ms after receiving a response.

3.4.1. When a command is issued before receiving a response, the function is not executed properly.
3.4.2. Except for when there is no Response for more than 5 seconds.

. . It takes about 5 seconds for internal initialization after plugging in AC power. During this time, it cannot process commands. Do not issue any command.
. . The number of characters of response to Status Read Commands depends on commands. Please see [7. Status Read Commands].

. . Characters for commands must be Capital (A - Z).

Command	“CR0” [CR]
Detail	Get the projector's operating status
Response	Acceptable	“%1” [CR]
	%1	“00” = Power ON “80” = Standby “40” = Countdown in process “20” = Cooling Down in process “10” = Power Failure “28” = Cooling Down in process due to Temperature Anomaly “88” = Coming back after Temperature Anomaly “24” = Power Save/Cooling Down in process “04” = Power Save “21” = Cooling Down is in process after Power off due to lamp failure “81” = Standby after Cooling Down due to lamp failure

[Details of Response]

"00" [CR]

Status : Power ON

Normal image is on the screen.

"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.

"40" [CR]

Status: Countdown in process

When "Display" in Setting Menu is ON and POWER ON is executed, it starts Countdown.

When "Display" in Setting Menu is OFF, processing Countdown is not executed and the status quickly moves to Power ON.

"20" [CR]

Status: Cooling Down in process

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 after lamp turns off and the fan spin finishes after about 90 seconds. The fan spin time depends on a model.

This function is used to cool down the lamps and other optical parts and is quite important for projector's reliability.

During this time, Functional Execution Commands are invalid.

"10" [CR]

Status: Power Failure

When the power supply voltage inside the projector reaches abnormal status, the projector is automatically turned off. The projector returns "10"[CR], which shows it moves to Power OFF status due to power failure. Fan also stops unlike Cooling Down status.

"28" [CR]

Status: Cooling Down in process due to Temperature Anomaly

When the inside temperature is out of the operating temperature, it automatically starts Cooling Down. Response for this status is "28"[CR].

Even if the temperature decreases during this process, Cooling Down is executed.

"88" [CR]

Status: Coming back after temperature anomaly

When the status moves to Standby after Cooling Down due to temperature anomaly, it returns "88" [CR].

This shows that the status turns to Standby because of abnormal temperature.

This status maintains until next operation is done. When Power On is executed, the information of temperature anomaly is canceled and normal operation is executed.

"24" [CR]

Status: Processing Power Save / Cooling Down

Power management function in Setting menu works and the status goes to Power Save / Cooling Down.

During this time, Functional Execution Commands are invalid (not executed).

This status moves to Power Save at set hours after the operation of Cooling Down.

"04" [CR]

Status: Power Save

This shows that it moves to Power Save status by Power management function in Setting menu.

"21" [CR]

Status: Cooling Down in process after turned off due to lamp failure

When a projector is turned off because of lamp failure, it automatically starts Cooling Down operation, in which the projector returns "21" [CR].

"81" CR

Status: Standby after Cooling Down due to lamp failure

This value is returned when Cooling Down operation due to lamp failure has been completed and the status has been moved to Standby. The status is kept until the next operation starts.

7.5.Input Mode Read Command

Command	“CR1” [CR]
Detail	Get the selected Input No.
Response	Acceptable	“%1” [CR]
	%1	"1" = Computer is selected "2" = HDMI is selected "3" = Video is selected LV-7292S/7297S/7292S: "1" = Computer is selected "2" = Video is selected
	Unacceptable	“?” [CR]

7.6.Lamp Time Read Command

Command	“CR3” [CR]
Detail	Get the total lamp running hours (Not actual lamp used hour, but Eco mode corresponding value).
Response	Acceptable	“%1” [CR]
	%1	Shows the time period with 5 digits numbers. Example “00410”[CR] shows 410 hours
	Unacceptable	“?” [CR]

7.7.Setting Read Command

Command	“CR4” [CR]
Detail	Get screen setting status such as Ceiling / Rear.
Response	Acceptable	“%1” [CR]
	%1	“11”[CR] = Normal Screen Setting “10”[CR] = Picture is top/bottom reversed. (Status: Rear Ceiling ON) “01”[CR] = Picture is left/right reversed. (Status: Rear ON) “00”[CR] = Picture is top/bottom and left/right reversed. (Status: Ceiling ON)
	Unacceptable	“?” [CR]

7.8.Temp Read Command

Command	“CR6” [CR]
Detail	Get the temperature data inside the projector. With some temperature sensors installed in the projector, it is possible to get all the temperature at once.
Response	Acceptable	“%1_%2_%3” [CR]
	%1 %2 %3	%1 Temperature of sensor 1 %2 Temperature of sensor 2 %3 Temperature of sensor 3 Temperature data is shown as “00.0”. When the temperature goes down to -, the first character becomes “-” instead of a space, like “-05.5” [CR]. When no temperature data can be returned due to hardware problems, the first character becomes “E” like“E00.0” [CR]. When several temperature sensors are equipped, Responses are returned continuously. “_31.5 _35.2 _33.4”[CR] The first data is sensor 1, then one space, and the data of sensor 2 follows.
