Software Installation

For details about how to add timebases and device drivers to the Server Configuration, refer to Adding, Configuring or Deleting Devices. When you add a driver to the timebase, the configuration dialog or wizard opens automatically. For information about the settings, click the Help button on a page or press F1.

Troubleshooting

Multi-Position valve: If the switching direction is wrong, reverse the direction via the Reverse Direction check box on the General tab page in the Properties dialog for the valve in the Server Configuration program.

 Note:

Usually, it is necessary to reverse the switching direction of the valve because of errors in the firmware. Therefore, the Reverse Direction check box is selected by default. Clear this check box if the valve firmware works correctly.

Further Information
