All RS232 connections are made through the serial I/O port. Connect the
9-pin D connector of a computer interface cable to the serial I/O port on
the instrument (Figure 1 on page 6). Connect the other end of the cable
to the computer serial I/O port (COM 1 or COM 2).
The instrument is equipped as Data Communication Equipment (DCE).
The instrument operates at 9600 baud with 8 data bits, no parity and one
stop bit. The computer or printer will not receive complete transmissions
if the device cannot continuously receive at 9600 baud.
Note: The use of the specified cable or an equivalent shielded cable is necessary
to meet radio frequency emissions requirements.
