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. PC Projector COM 1 Control Port CD N.C. RXD RXD

3. Notes for Communication

1. The projector control command is defined as one command/one line that starts with “C” and ends

with carriage return (0x0D).

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: “CRO” [CR]

3. Whenit 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 (0x0D) after the projector receives the first data “C”. 4... For Command pipelining, wait for the interval of 100ms after receiving a response. More than 100ms Command Next Command PC — Projector “C” “0” | “7” CR Projector — PC ACK | CR ! Response (Afew ms — 5s)

3.4.1. When a command is issued before receiving a response, the function is not executed

3.4.2. Except for when there is no Response for more than 5 seconds.

5. 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.

6. The number of characters of response to Status Read Commands depends on commands.

Please see [7. Status Read Commands]. 7... Characters for commands must be Capital (A - Z).

CIE DISPLAY CLEAR C3E ———

——— means no function.

6. Functional Execution Command

6.1.1 PC issues a command in format as below.

“c” [CR] Command: two characters (See Basic Functional Execution Command Table) A projector changes received data to decode and returns a result after being ready to receive next command. [ACKI]LCR]: (0x06, 0x0D)When received Functional Execution Commands.

6.1.2 “?”[CR]: When the received data cannot be decoded.

6.2. Command Pipelining When some functions need the command pipelining, the performance is the same as that of the remote control;

6.2.1. System: issues any command every 100 ms.

6.2.2. When receiving the appropriate command, the function is executed for 120 ms from the

6.2.3. When receiving the same command continuously within 120 ms, the function is executed

for another 120 ms from the moment.

6.2.4. When there is no incoming command after 120 ms, the execution of pipelining is stopped.

6.2.5. When the projector receives other incoming commands within 120ms, the execution of

pipelining is stopped. 6.3. Transfer Example Switch the projector to video mode with Basic Command. Command PC — Projector “C’| “0” “7” | CR Projector —+ PC ACK| CR Processing : (Afewms — 5s)

LV-7290/ LV-7295/LV-7390/ LV-8225 Basic Serial Command Specifications [Details of Response] “00” [CR] “80” [CR] “40” [CR] “20” [CRI] “10” [CR] “28” [CR] “88” [CR] Status : Power ON Normal image is on the screen. Status: Standby When the status is Standby, Status Read Commands are always acceptable, but Functional Execution Commands are not acceptable except POWER ON Command. 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. Status: Cooling Down in process When the status is Power ON, and POWER OFF Command (“CO1"[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. 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. 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. 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

LV-7290/ LV-7295/LV-7390/ LV-8225 Basic Serial Command Specifications 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 1 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. Status: No signal 1 Power Save / Cooling Down 1 Power Save Response: “00” ' “24" ! “04” 5 minutes ke no signal After aboût 90 sec. “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.
