USB
The NVITE reader features an USB interface for service, installation and firmware upgrade purposes. The Mini-USB
connector is located on the bottom of the device and can only be reached when the bottom screw is opened and the
reader is lifted away from the base-plate. This ensures that unauthorized modifications to the reader settings can be
detected using the tamper switch.
USB Driver installation
Make sure your computer is connected with internet. Connect the NVITE reader to your computer via the USB cable.
The USB drivers may be installed automatically. In case you need to install the USB drivers manually, please go to the
website
www.ftdichip.com/Drivers/VCP.htm
and download the VCP (Virtual Com Port) drivers. After successful
installation of the USB drivers the reader will appear in the Windows device manager in "Ports (COM & LPT)" section.
