uPASS Access | installation guide
13/
3.2.2 USB
The uPASS Access 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 uPASS Access is lifted away from the base-plate. This ensures that unauthorized modifications to the
reader settings can be detected using the tamper switch.
The USB interface can be used to configure the reader using the UHFTOOL software.
USB driver
Make sure your computer is connected with internet. Connect the uPASS Access 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.
Notes
• While the USB cable is connected, the RS485 interface is disabled !
