RS-232 interface operation
Sending and receiving data
The RS-232 interface transfers data using eight data bits, one stop bit, and no parity. Make
sure the controller you connect to the multimeter also uses these settings.
You can break data transmissions by sending a ^C (decimal 3) or ^X (decimal 18)
character string to the instrument. This clears any pending operation and discards any
pending output.
You can break an RS-232 transmission of buffer readings by pressing LOCAL and then
EXIT. The next command to send buffer data (i.e., TRACe:DATA?) will start at the
beginning, rather than where the transmission was halted.
Baud rate
The baud rate is the rate at which the Model 2700 multimeter and the programming
terminal communicate. Choose one these available rates:
• 19.2k
• 9600
• 4800
• 2400
• 1200
• 600
• 300
The factory selected baud rate is 4800.
When you choose a baud rate, make sure that the programming terminal that you are
connecting to the Model 2700 can support the baud rate you selected. Both the multimeter
and the other device must be configured for the same baud rate.
