RS-232 Communications
RS-232 Connection
Use an approved RS-232 connector and null modem cable when
connecting the Ethernet/RS-232 Interface to your computer. The RS-232
connector uses the 9 pin mating connector on the rear panel. Figure 2-5
shows the pinouts for the RS-232 connector.
Refer to Figure 2-2 on page 2–5 for the position of the RS-232 connector
on the rear panel subplate.
WARNING
Do not operate the power supply and the computer at
significantly different frame potentials. The interface
connection system may not be capable of handling the resulting
excessive ground currents.
