TLON
= TeleLarm Local Operating Network = a LonWorks
network for communication between several units/nodes.
protocol is 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 is plugged in the control
unit. (Old installations: Some control units, not prepared for network
connection, could be connected via a serial interface and a Gateway).
A network can be one sub net (FTT-10) or several sub nets, 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.
All network programming (configuration) are made with the PC
program "TLON Manager".

LED (Light Emitting Diode) = Yellow, green or red optical indicator
("lamp").
External Indicator (LED)

built-in LED. Old installations: Also connected to an ADB.
