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 controllers normally use a 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.

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.
Set command example 1
: SOURCE 21
Colon from projector Command Space Parameter Return
Set command example 2
: VOL INC
Colon from projector Command Space Parameter Return
2.2.Get command format
A get command consists of a command and ?. Projector returns a response parameter after executing the command.
Get command example
: SOURCE?
Colon from projector Command ? Return
Response parameter example
SOURCE = 21
:
Colon from projector Command = Parameter
2.3.Null command
The null command is a 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.
ERR

4.1.Standby state (operation indicator is in orange)
When a projector is in a standby state, executable commands depend on projector models and standby configuration (network on, network
off). Refer to the following table.
(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.
Null command is command name for "ENTER" or "RETURN" key of the keyboard
The reply is ":"

4.3.Error Status
A projector returns the error status when a projector receives "ERR?" comma nd.
The following projectors can return the error status while the projectors become the cool-downs status at an error and the projectors become
the error status after cooling down.
EMP-1700/1705/1710/1715, 6000/6100/6110/6010, 1815/1810/1825, S5/X5/83/822, 260/280, 400W
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 become the cool-downs status at an error.
The following table shows the return codes and the meaning of error status.
CommandReturne code
00:There is no error or the error is recovered
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
09: Electric dual-layered capacitor is disconnected
0A: Auto iris error

5.Command transmission timing
5.1.Standby state
1) For all model 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 t he
SOURCE (note3)-5 seconds (note 2)
All others-3 seconds
20 seconds
20 seconds
5 seconds
(note1) When a projector receives the PWR ON co mmand, i t tries to ignite the lam p by a ctivating the ballast u nit. I n case tha t 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 video 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”.
(note 4) Projectors execute the PWR OFF command after they start completely.
(note 5) 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.
