TCP/IP via Ethernet is used to connect the Recorder to a PC for downloading recorded data, and for configuring the Recorder when not using the PDA. This is the recommended method of data transfer due to its speed and reliability.

To avoid this, use the supplemental ground terminal only when no protective earth ground connection exists through the line power cord. If there is any chance that a safety ground connection does exist through the line power cord connection, make sure to connect the supplemental ground terminal only to the ground system used by the ac receptacle that powers the Recorder.

Ground Terminal
Connecting the supplemental ground terminal and the line cord safety ground to different
ground potentials creates a ground loop that can damage the Recorder. To avoid this, use the
supplemental ground terminal only when no protective earth ground connection exists through
the line power cord. If there is any chance that a safety ground connection does exist through
the line power cord connection, make sure to connect the supplemental ground terminal only to
the ground system used by the ac receptacle that powers the Recorder. See Figure 3.
