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 projec-
tors.
•Serial connection

•USB connection
A USB interface can be used to control a projector. Refer to Appendix for details.
