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) charac-
ter 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 begin-
ning, rather than where the transmission was halted.

Baud rate

The baud rate is the rate at which the Model 2750 multimeter and the programming termi-
nal communicate. Choose one these available rates:
•
•
•
•
•
•
•
The factory selected baud rate is 4800.
When you choose a baud rate, make sure that the programming terminal that you are con-
necting to the Model 2750 can support the baud rate you selected. Both the multimeter and
the other device must be configured for the same baud rate.
