PLC-XW55 Basic Serial Command Specifications
1. Overview
1.1. These specifications define projector control commands for PLC-XW55 (0.6” XGA).
1.2. The projector control commands are used to remotely control a projector through RS-232C from a
computer.

Notes for Communication
3.1. The projector control command is defined as one command/one line that starts with “C” and ends
with carriage return (0x0D).
3.2. 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]
3.3. When it takes more than one second to receive one command, it does not operate.
It clears the information of buffer when the projector receives LF (0x0A) or EOF (0x1A) and takes
more than one second to receive one command.
3.4. For Command pipelining, wait for the interval of 100ms after receiving a Command.
More than 100ms
Command
PC → Projector
“C”
“0”
“7”
Next Command
CR
Projector → PC
ACK
CR
Response
(A few ms ∼ 5s)
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.
3.5. 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.
3.6. The number of characters of response to Status Read Commands depends on commands.
Please see [7. Status Read Commands].
3.7. Characters for commands must be Capital (A - Z).

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)
6.1.2. 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.
6.1.3. “?”[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: issue 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.

Status Read Command
7.1. Format
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].

“%1” [CR]
”00” = Power ON
“80” = Standby
“40” = Processing Countdown
“20” = Processing Cooling Down
“10” = Power Failure
“28” = Processing Cooling Down due to Temperature Anomaly
“88” = Coming back after Temperature Anomaly
“24” = Processing Power Save/Cooling Down
“04” = Power Save
“?” [CR]
[Details of Response]
7.3.1. “00” [CR]
Status : Power ON
Normal image is on the screen.
7.3.2. “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.
7.3.3. “40” [CR]
Status: Processing Countdown
When “Display” in Setting Menu is ON and POWER ON is executed, it starts processing
Countdown.
When “Display” in Setting Menu is OFF, processing Countdown is canceled and the
status quickly moves to Power ON.
7.3.4. “20” [CR]
Status : Processing Cooling Down
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.

7.3.5. “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.
7.3.6. “28” [CR]
Status: Processing Cooling Down 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.
7.3.7. “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.
7.3.8. “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
Response: “00”
Power Save / Cooling Down
Power Save
“24”
“04”
5 minutes with no signal
After about 90 sec.
7.3.9. “04”[CR]
Status : Power Save
This shows that it moves to Power Save status by Power management function in
Setting menu.

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.
Acceptable
Response
%1
%2
%3
Unacceptable
“%1_%2_%3” [CR]
%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.
