tira89e1-a (2014-03) RS232 ASCII.cp
The RS232 ASCII Serial Interface for Cube CDGsci permits the communication
between this digital INFICON Capacitance Diaphragm Gauge and
• a computer or
• a general device that understands RS232 ASCII.
The protocol is easy to implement and best suited to try out certain parameters of
the Cube gauge before programming an interface because it can be directly
accessed by a terminal program such as
• Windows XP terminal program
• Any other terminal program that can communicate on a RS232 interface.
The RS232 ASCII 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 RS232 ASCII
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 RS232 ASCII Serial Interface and DeviceNet, Profibus, or the
diagnostic port.
