Data Interface

The AE20204 LC Meter has a RS232 or a USB (optional)
interface. This allows to access the measurement values from a
computer. The USB driver creates a virtual serial (COM) port.
This makes integration with external tools and applications
very easy.

System Requirements

RS232 Interface:

- free serial port

USB Interface:

- MS Windows®

98/ME/2000/XP/Vista/7/8/

Server 2003/Server 2008/Server 2008 R2/
