Connect to a printer or computer
Use the serial interface (RS232) connector on the back of the instrument
to transmit data from the instrument to an external printer or a serial
communication port on a computer. Refer to Figure 2 on page 9.
To connect a serial printer to the instrument, use a printer cable
assembly that is terminated with a standard 25-pin D connector. A serial-
to-parallel converter can be used to print to a parallel printer. Data is
transmitted to a printer as a 39-character string plus the line feed and
carriage return.
To connect a computer to the instrument, use a serial communication
cable with a DB9 connector.
Note: Use of the specified cable or equivalent is mandatory for CE compliance (a
shielded cable assembly must be used).

Computer (RS232) commands
A communication program (i.e., such as Window Terminal or ProComm
Plus) is recommended for computer operation of the instrument.
Configure the communication program to the RS232 connection settings.
Refer to Configure the RS232 connection on page 41.
Table 5 shows the RS232 command set for the instrument.
