1 Overview
・
This specification defines projector control commands for the PLV-WF20.
・
The projector control commands are designed to remote-control a projector through RS-232C
from a computer.
・
Refer to [8. Command with Address Specification] when using commands with address.
2 Serial Interface Specification
2.1 Transfer Specification
Items Specification
Synchronous system Asynchronous
Transmission Speed 9600 / 19200
Data Length 8 bits
Parity None
Stop Bit 1
Flow Control None
1) Transmission speed: initial setting value is 19200.
2) Transmission speed can be changed in Service Mode.
2.2 Connection
Dedicated serial cables that come with a projector must be used for the connection to a
computer and the projector.
PC Projector
COM 1 Serial Port IN
(D-Sub 9Pin) (D-Sub 9Pin)
Connect COM port of the computer to SERIAL PORT IN of the projector.
COM Port (COM1 or COM2) of a computer is specified by control software of the computer.

3 Notes for Communication
・ The projector command is defined one command per line that starts “C” and ends carriage return
(0x0D).
・ When the projector receives the carriage return, it starts decoding.
・ There are two types of command, Functional Execution Commands and Status Read Commands.
Example of Functional Execution Command: “C05” [CR]
Example of Status Read Command: “CR0” [CR]
・ It clears the information of buffer in the following cases.
- When the projector receives LF (0x0A) or EOF (0x1A9).
- When it takes more than one second to receive a single command.
(Until receiving the carriage return after the reception of the first data.)
・ When pipelining control commands, allow interval time as below after the reception of response,.
1) [ZOOM UP/DOWN] [FOCUS UP/DOWN] [LENS SHIF UP/DOWN/LEFT/
RIGHT] commands…100ms
2) Other commands…500ms
・ When pipelining Status Read command, allow at least 500ms of interval time after the response.
・ Do not issue any command before receiving the response except the case that there is no response
for 5 seconds.
・ It takes about 7 seconds for internal initialization after plugging in AC. During this time, it cannot
process command. Do not issue any commands.
・ For 7 seconds after starting POWER ON in the status of STANDBY, the projector returns
“Acceptable” response, but it does not carry out the command. Status Read commands are
carried out in 500 ms after the “Acceptable” response is returned.
・ About the behavior during Count Down and Cooling Down operation; in the period of the Count
Down operation after Power ON or Cooling Down after Power OFF, “Acceptable” response is
returned, but the command is not carried out except for Status Read command.
・ About the behavior during switching inputs; it takes 5 seconds to switch inputs after receiving the
command. During this period, even if another command is received, it is not carried out although
returning “Acceptable” response. However, Status Read commands are carried out in 500 ms after
the “Acceptable” response is returned.
・ The length of the returned value for Status Read command in successful operation depends on the
command.
・ The characters for commands must be in uppercase (A - Z). Those in lowercase can not be used

6 Functional Execution Command
6.1 Format
1) PC issues a command in the format below:
“C” Command [CR]
Command: two characters (Refer to Functional Execution Command Table)
2) A projector decodes the received data and returns the result after getting ready to receive
another command.
[ACK] [CR]: (0x06, 0x0D) When the projector has received Functional Execution
Commands.
“?” [CR]: When the received data cannot be decoded
6.2 Command Pipelining
Functions which need command pipelining follow the rule below.
- Sender system issues any command every 100ms.
- When receiving the applicable command, the function is executed for 120ms from the
moment.
- When receiving the same command in succession within 120ms, the function is executed
for another 120ms from the moment.
- When there is no incoming command after 120ms, the execution of pipelining is stopped.
- When the projector receives incoming other command within 120ms, the execution of
pipelining is stopped.

6.4 Operation Requirements
When the projector is in the status below, Functional Execution Commands are limited.
(Status Read Commands are available in following status)
Projector Status Available Functional Execution Commands
In Standby mode C00: POWER ON
Count Down in process C00: POWER ON (Countdown is terminated)
Cooling Down in process NONE (No Execution)
Cooling Down in process due to abnormal
temperature
NONE (No Execution)
In Abnormal Temperature NONE (No Execution)
In Abnormal Power Status NONE (No Execution)
On switching modes NONE (No Execution)
Power Saving Cooling Down in process NONE (No Execution)
In Power Saving status
