Network Master Wiring
The Network Master is a hardware device used to
connect all display units at a location over a RS485
network, so feed inventory and water consumption
information can be collected and retrieved, either
locally or remotely via a call center server computer
that sends either text or email messages.
Feed-Link 3 is a windows based PC program that is
used to direct connect to the Network Master. This
information can be accessed real time from either
a PC directly connected to the Network Master or
remotely through an internet connection.
(See Figure 7F.)
The Network Master comes with jacks for ethernet
and PC connections. It has plugs for power and
RS485 communication.
