The Meter communicates with a host through a DB-9 interface connector on the rear
panel of the Meter. A connector pinout for the RS-232 interface is provided on the rear of
the Meter.
To connect the Meter to a personal computer (with DB-9 connector), use a Fluke RS41-3
Null modem cable. Refer to Table 1-3.
To connect the Meter to a specific brand of RS-232 printer, use the cable that would be
used to connect that printer to an RS-232 port on a personal computer with a DB-9
connector.

When connecting the Meter to the host or terminal, use a cable appropriate
to your application. It is recommended that you use a cable that is less than
50 feet long (15 meters), as this will help prevent performance degradation.
Longer cables can be used if the load capacitance at the interface point
(including signal terminator) is less than 2500 pf.
