When charging the hand terminals of the SC 920G vacuum
pump system, use only the original power supply from KNF.
Several different vacuum pump systems may be operated
simultaneously with their respective hand terminals within the
wireless connection range.
The wireless connection between hand terminal and vacuum
pump system is robustly resistant to operation of mobile
telephones and Bluetooth devices in the immediate area.
4.3. Software
The USB connection between the PC and the vacuum pump
system is operated as an RS232 interface. Accordingly, in the
operating system it is managed as an additional COM connection
and can be addressed with conventional terminal software. Please
see the delivered CD for information on operating the vacuum
pump system via software.
