Ethernet standard 10Base-T or 100Base-T can be used, however the facility wiring must
be appropriate for the speed of the network to prevent intermittent problems from
occurring. For particle counter installations, Ethernet standard 10Base-T is sufficient to
transmit data and is more forgiving of installation errors.
•
Length—100 meters maximum single wire length (repeaters can be used to increase
the distance)
•
