3.3 USB Interface module
The 4 pin connector of the USB Interface module can be attached directly to the AD Converter
module. A mini USB cable can be attached to the mini USB B connector.

The USB interface provides a USB 1.1 or 2.0 connection to a computer (note the USB interface is not
USB 3.0 compatible). It is possible to connect multiple USB interface modules to one PC, up to the
current limit of your USB ports.
USB Driver Installation:
Normally Windows will recognize the USB interface as a USB to COM port converter. Windows will
install the driver automatically or download the driver from the internet. In some cases the driver
needs to be installed manually. The latest drivers can be downloaded from the FTDI website.

When Windows has installed the driver properly it will assign a COM port number to the USB
Interface. Through this port number the communication can be established. Look up at your device
manager to find out the assigned port number. The figure below shows an example that Windows
has assigned COM4 to the connected USB interface.
