Computer Requirements

Operating System

Windows 10 or higher operating system is required.

Desktop Installation Required

The application should not be installed on a network drive with shared access.

Multiple users cannot operate the application at the same time.

Ensure the "Sleep" setting on the desktop is set to "Never" to avoid interruption while running an analysis. If this occurs, the application loses network connectivity with the instrument and a communications error will be reported. A restart of the Windows application may be required if automatic reconnection is not successful.

10 Base T or 100 Base T Ethernet Port

If the computer is to be connected to a network, two Ethernet ports are required. If more than one Ethernet-based unit is connected to the same computer, an Ethernet switch will also be required.

Read/Write Permissions

All application users will need Read/Write permission to all directories and subdirectories where the application is installed.

Drives

USB port
