Ethernet Network
The Ethernet Network can be used to connect one or more DragonFly units back to a PC / Laptop for remote
simultaneous configuration, real time clock synchronisation, live data feeds from Ethernet based sensors or internet
based RSS feeds, and live multicast IPTV based video or an IP camera feed.
The Ethernet network uses standard IP based protocols, and so standard CAT5 cabling and Ethernet switches may be
used. For certain features, managed Ethernet switches are recommended, and may need to be specially configured
for IGMP traffic (see information on the Video Canvas for more information, or contact Drucegrove directly).
The following diagram shows how a TFT024 should be networked from an elevator car back via a machine room to a
central building management room:
Note that the maximum distance of an Ethernet run is 100 meters (328 feet), and if the trailer run from the TFT
screen back to an Ethernet switch is over this distance,
Ethernet Extenders
need to be used (as shown in the above
diagram). If the distance is less than 300 feet, a CAT5 trailer may be used without Ethernet Extenders.
Note: All Ethernet wiring needs to be
twisted pair
. If there are untwisted sections, the network will not work.
