for communication between several units/nodes. The
protocol is called LonTalk and the transmission works with doubly-
terminated bus topology (Echelon FTT-10). To connect a control unit
to the network, a TLON connection board has to be plugged in the
control unit. EBL512 G3 also supports redundant TLON system
communication. In this case two TLON connection boards have to be
plugged in each control unit.
A network can be one channel (FTT-10) or several channels,
connected via routers. (In the TLON Network a sub net = a channel.)
Routers are also used to increase the maximum cable length, node to
node, in a network.
Router or Repeater is the same type of unit (different configuration).
All network programming (configuration) are made with the PC
program "TLON Manager".

replaced with a key switch.
An open door is indicated in the LCD (i.e. an "open door" icon).
