MULTI-CHANNEL SYSTEM
In a multi-channel system where each channel is run on its own cable and
connected only to single-channel remote stations as in the following diagram,
there are no crosstalk issues because the channels do not share a common
ground. Consult the table “Belden Shielded Cables” in the next section for
cable recommendations.
Figure 2-3: Multi-channel System
In a multi-channel system where multiple channels are run from the PS-704 to
multiple channel stations as in the following diagram, crosstalk can be an
issue. This is because the channels will share a common ground at both ends
of the cable run. If this kind of connection will be used, refer to the section
“Crosstalk Considerations.”
