The RS232C Serial Interface for Cube permits the communication between this
digital INFICON Capacitance Diaphragm Gauge and
• an appropriate controller or
• a
computer.
The RS232C Serial Interface integrated in the Capacitance Diaphragm Gauge
allows to digitally transmit measurement values and information on the gauge
status as well as to make parameter settings.
Caution
Caution: data transmission errors
Any attempt to simultaneously operate the gauge via the RS232C
Serial Interface and a fieldbus interface (DeviceNet or Profibus) or the
diagnostic port may result in incorrect data and data transmission
errors.
Therefore, it is inadmissible to simultaneously operate the gauge via
the RS232C Serial Interface and DeviceNet, Profibus, or the
diagnostic port.

The part number (PN) can be taken from the product nameplate.
If not indicated otherwise in the legends, the illustrations in this document corres-

We reserve the right to make technical changes without prior notice.
The RS232C Serial Interface is used in duplex operation. The gauge continuously
(approximately every 100 ms) transmits a nine byte send string without request.
Instructions to the gauge are transmitted via five-byte receipt strings.
The RS232C Serial Interface is only available on the DIAG port.
