EMP NS Connection failures caused by Remote Control applications

Subject:

This bulletin was created to inform you of an issue that can occur when using the PowerLite

735c/7850p, 8300i (with EasyMP.net module) and remote control software.

Description of Issue:

The user attempts to run EMP NS Connection on Windows 98SE/Me/2000/XP with the PowerLite

735c/7850p/ 8300i (with EasyMP.net module). When the EMP NS Connection application is

launched, it immediately gives an error message stating that EMP NS Connection "FAILED TO

INITIALIZE."

Reason:

Epson has found that remote control software, like PCAnywhere and RealVNC, causes a conflict

with the EMP NS Connection application. These remote control applications use a "Video Hook

Driver" that conflicts with the Epson GDI Monitor driver that is installed and used by EMP NS

Connection. Most remote control programs load a small client application at Windows startup and

leave an icon in the system tray (located at the bottom right on the desktop) to indicate they have

been loaded. In most cases, the remote control software can be turned off by right-clicking on the

icon in the system tray and disabling or exiting the program. Remote control applications do not

have to be removed from the system in order for EMP NS Connection to run properly; they just

need to be turned off. Consult the documentation that came with the remote control software for

information on how to disable the software from automatically launching every time the computer is

started.

Once the remote control software has been turned off, EMP NS Connection should run without

returning an error. If you continue to have issues connecting to the projector, consult the EMP NS

Connection Help file or User's Guide for troubleshooting assistance.

Notes:

VNC stands for Virtual Network Computing. It is a remote console utility which allows a user at his

computer to assume control of another computer across a network, as if they were sitting in front of

that computer.
