Basic Serial Command Specifications
1. Overview
1.1. These specifications define projector control commands for PLC-WL2500 / WL2501.
1.2. The projector control commands are used to remotely control a projector through RS-232C from a
computer.
2. Serial Interface Specifications
2.1. Transfer Specifications

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: “CR0” [CR]
3. 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
(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
PC → Projector “C” “0” “7” CR Next Command
Projector → PC ACK CR
Response
(A few ms 〜 5s)
4.1. When a command is issued before receiving a response, the function is not executed properly.
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).

6. Functional Execution Command
6.1. Format
6.1.1 PC issues a command in format as below.
“C” COMMAND [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.
[ACK][CR]：(0x06、0x0D)When received Functional Execution Commands.

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
moment.
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.

7.1.1. PC issues commands in format as below;
“CR” Command [CR]
Command：1 character(See Basic Status Read Command Table)
7.1.2. When a projector receives the appropriate command, it returns a character line as the
required data.
Required Data [CR]
Required Data：A character line(See Basic Status Read Command Table)
7.1.3. When the received data cannot be decoded, the projector returns “?” [CR].

Response
%1
“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]
“40” [CR]
“20” [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.
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 (“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.
“10” [CR]
22/25
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
Page 23

/WL2501
Basic Serial Command Specifications
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.
Status： No signal Power Save / Cooling Down Power Save
Response： “00” “24” “04”
5 minutes with no signal After about 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
23/25
completed and the status has been moved to Standby. The status is kept until the next
operation starts.

7.8. Temp Read Command
Detail
Response
With some temperature sensors installed in the projector, it is possible to get all
the temperature at once.

%3＝Temperature of sensor 3
Temperature data is shown as “00.0”.

Unacceptable “？”[CR]
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.
