Technical Support Notes

EPSON RC+ is designed to easily upgrade previous versions.  You should always check the readme.txt file located on the CD in the EPSON RC+ directory for the latest information.

When to upgrade
If a bug was fixed in the upgrade version, or you require a new feature in the upgrade version, then you should upgrade.  The readme.txt file mentioned above contains a list of bugs fixed and new features for each version.  If your production code is running properly, then there is no need to upgrade.  It is recommended that you upgrade on a test system, if possible, to verify that your production code is working properly. 

Upgrading EPSON RC+
1. Although it is not required, it is recommended that you run MKVER before upgrading to save your system configuration. 
Select Tools | Maintenance, then click MKVER. Enter a name such as with today's date: v051500 and save it to floppy.  If you decide to uninstall the previous version of EPSON RC+, the robot setup information will be removed. After installing the new version, you can use SETVER from Tools | Maintenance to restore the system configuration.

2. It is recommended that you install the upgrade without uninstalling the previous version. With this method, the upgrade software will know which options were previously installed and your system configuration will be preserved.  As mentioned above, if you decide to uninstall the previous version before upgrading, you should execute MKVER first, then SETVER after installing the new version.

3. Before you start installing the new version, ensure that the SPEL Runtime Drivers are shutdown. If you see the robot icon in your Windows system tray, then right click on the icon and select Shutdown SPEL Drivers. If you attempt to install when the drivers are running, you will receive a message to shutdown the drivers before you can proceed. In this case, you will have to start the setup program again by re-inserting the CD or double clicking on the CD icon in My Computer.

Reverting back to previous version after upgrade
In most cases, you can go back to the previous version without problems by simply running the installation program.  However, if you added new hardware that is only supported in the upgrade, such as new robot models or vision frame grabbers, then you may encounter errors, since the previous version does not support the new hardware.  In this case, uninstall EPSON RC+, then reinstall the previous version, and finally execute SETVER to restore system configuration.
