Communication Protocol RS232 ASCII Serial Interface Cube CDGsci RS232 ASCII tira89e1-a (2014-03) 1
General Information 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.
Functional Principle Data format tira89e1-a The RS232 ASCII Serial Interface is used in duplex operation. • ASCII • 8 data bits • 1 stop bit • no parity bit • no handshake Transmission rate • 9600 Baud Pin assignment • TxD Pin 13 • RxD Pin 14 • GND Pin 5 (sensor cable connector) (2014-03) RS232 ASCII.
1 Interface Protocol 1.1 Send and Receive Commands are send to the Cube gauge as an ASCII string. Each command is terminated with an CR/LF. The input of only the command results in Cube sending the actual value of the parameter corresponding to the command (read access). The value is transmitted as an ASCII string terminated with a CR/LF. The input of the command with a trailing parameter value will result is a writing attempt of the value into the corresponding parameter on the Cube.
