USB Ports (no
RS-232)
Modern computers, particularly notebooks, often have no RS-232 ports at all, but
are equipped with two or more USB-ports. In such a case the instrument and the
Control Unit must be connected via appropriate USB to Serial converters
according to the following figure.
Note:
The connection of the computer to the instrument via an USB to Serial
converter will reduce the communication speed between the instrument and the
computer. As a consequence, the execution time for the Gravimetric Test may
increase by 10 to 20 %, compared to the time it takes when the instrument is
connected to the computer directly.
Recommended converters: See sections
