    Meilhaus Electronic Intelligent Driver System (ME-iDS). Software Support The ME-series is supported by the Meilhaus Electronic Intelligent Driver System (ME-iDS). The ME-iDS is a unique driver system covering different devices and operating systems. It supports Windows 7, 8.1, 10 and con- tains a universal function library (API) for all common programming lan- guages.

  • Page 9: Initial Operation

    First choose a directory on your computer (e.g. C:\Temp\Meilhaus\ME-iDS). Use the Meilhaus Electronic Intelligent Driver System (ME-iDS) for pro- gramming your new data acquisition hardware. For installation and opera- tion of the driver system, please follow the documentation in electronic form included with the software package.
