3.6.6 Ethernet wiring
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)
• Repeaters—4 maximum
• Connector type—RJ-45 (standard Ethernet wiring convention T-568B)
Refer to Figure 14 and Table 5 to install a particle counter with Ethernet communication.
