ESC/VP21 Command User’s Guide for Business Projectors
1. Introduction to ESC/VP21
ESC/VP21 is a control command and protocol for Epson projectors, which is used for A/V controller to control and
monitor Epson projectors. The command codes are comprised of ASCII codes. Therefore the command codes can be
understood very easily and you can easily control projectors using a PC with a terminal emulator such as Microsoft Hyper
terminal.
Since ESC/VP21 is independent of communication protocols. Serial, USB or TCP/IP network can be used to transmit the
commands to projectors.
* Serial connection
A/V controller normally use as serial connection to control projectors. Refer to Appendix for details.
* USB connection
A USB interface can be used to control a projector. Refer to Appendix for details.
* Network connection
After establishing a TCP session, ESC/VP21 commands can be sent to projectors. Refer to ESC/VP.net protocol manual
ESC/VP21 Command User’s Guide for Business Projectors
2. ESC/VP21 Command Formats
2.1. Set command format
A set command consists of a command and a parameter. Projector returns a colon after executing the command.
There are two types of parameters. One is fixed such as ON, OFF, or 21. Other is a step parameter such as INC, DEC or
INIT.
INC: increments the parameter by one.
DEC: decrements the parameter by one.
INIT: initializes the parameter.
2.2. Get command format
A get command consists of a command and ?. Projector returns a response parameter after executing the command.
2.3. Null command
The null command is as command code of the return key code (Hex 0D). Projector returns a colon。The null command
can be used to confirm that the projector is in operation.
2.4. Illegal commands
Projector returns “ERR” and a return key code (Hex 0D) and a colon when it receives invalid commands.

4. Projector state and commands
4.1. Standby state (Operation indicator is in orange)
When a projector is in a standby state, executable commands depends on projector models and standby configuration (network
on, network
off). Refer to
the
(note1) EMP-61/81/830/835/740/745/821/828 returns “ERR” when it received commands other than PWR ON, PWR?, LAMP? and
Null commands.
(note2) EMP-7800/7850 returns “ERR” when it received commands other than PWR ON, PWR?, SOURCE? and Null commands.
(note3) EMP-8300/9300 returns “ERR” when it received commands other than PWR ON, SOURCE xx, PWR?, SOURCE? and Null
commands
All projectors returns “ERR” when the command format is not good. All projectors returns “ERR” when the projector is not ready to
reply the command. A null command is command name for “ENTER” or “RETURE” key of the keyboard the reply is “:”.
4.2. Power on state (Operation indicator is in green)
All commands are executable.
ESC/VP21 Command User’s Guide for Business Projectors
5. Command transmission timing
5.1. Standby state
1). For all mode with the standby configuration of “network on”
The first command can be sent anytime and the subsequent commands should be sent after receiving a colon from the
projector.
2). Other than 1)
PWR ON can be sent any time.
5.2. Power on state
A command should be sent after receiving the colon of the previous command from the projector. The following is an
exception. When the PWR OFF command is sent to 7800/7850/8300/9300 with the standby configuration of “network off”,
the subsequent command should be sent 10 seconds after the colon is received.
In case that you can not wait for the colon and send a command after receiving it, instead send a command after the
execution time listed in the following table.
ESC/VP21 Command User’s Guide for Business Projectors
Command Models Execution time
PWR ON
PWR OFF (note4)
SOURCE (note3) - 5seconds (note2)
All others - 3seconds
(note1) When a projector receives the PWR ON command, it tries to ignite the lamp by activating the ballast unit. In
case that the lamp fails to be ignited, it tries to ignite the lamp three times at maximum. When the lamp fails to be
ignited three times, it is a lamp failure.
The projector returns a colon within 40, 70 and 100 seconds when successful in the first, second and third times
respectively.
(note2) When the input vide sync signal is stable, a colon is returned within 5 seconds. However, it may take more than
5 seconds when the input video sync signal is unstable.
(note3) Projector initiates the process of the input video signal recognition when it receives a SOURCE command. If
the signal of the video input is changing (for example, from SVGA to XGA by A/V controller) during the process of
the input video signal recognition, the projector returns “ERR”.
(note4) Projectors execute the PWR OFF command after they start completely.
(note5) Projectors might return “ERR” when “Quick Setup” and “Auto Focus” functions are set to ON.

5.3. Warning and abnormal cases
Projector executes commands normally while a warning indicator such as a high temperature warning is on.
Projector does not execute commands nor return a colon when the projector is in an abnormal state such as a lamp
failure and abnormal high temperature.
As for EMP-6100/6000, EMP-1715/1710/1705/1700, EMP-1815/1810, EMP-S5/X5/83/822 and the following models,
when an abnormal state is continued for 130 seconds after, PWR ON command becomes possible.
ESC/VP21 Command User’s Guide for Business Projectors
6. Error Status
A projector returns the error status when a projector receives "ERR?" command.
The following projectors can return the error status while the projectors become
the error status after cooling down.
EMP-1700/1705/1710/1715, 6000/6100/6110/6010, 1815/1810/1825, S5/X5/83/
EB-G5000/G5100/G5150/G5200W/G5300/G5350
And later models.
[The other models except the above models]
The models except the above models can return the error status while the projectors
The following table shows the return codes and the meaning of error status.
Command Return code

01 : Fan error
03 : Lamp failure at power on
04 : High internal temperature error
06 : Lamp error
07 : Open Lamp cover door error
08 : Cinema filter error
ERR?
09 : Electric dual-layered capacitor is disconnected
0A : Auto iris error
0B : Subsystem Error
