USB drivers for the R100 are installed automatically when using Windows Update. We recommend you carry this out first so Windows can handle the installation. Should this process prove problematic, or if you need to manually install the drivers, please download and use either:
- the CDM20828_Setup installer (if your R100 serial number is 412000119xxxxxxx or lower)
- the SRT_USB drivers zip file (if your R100 serial number is 412000120xxxxxxx or higher)
If you're using the R100 on a Linux or macOS machine it should automatically use the standard USB to serial driver. However, if you require the USB drivers for manual installation they are also attached.
