Basic Design Data
1. The central control software communicates via an Integrated Control Interface (ICI) or
Integrated Control Interface Plus (ICI+) to the ICMs on the course. The ICI(+) should be
mounted indoors and located as near the central control computer as possible. It is possible
to remotely locate an ICI(+) by radio. See page 21 for additional details. System capacity is
determined by the level of central control software as well as the hardware within the ICI(+).
2. The IC System operates a maximum of 750 individually controlled ICMs per wire path.
a. For IFX Hybrid systems (Satellite controllers and ICMs on the same wire path) the
maximum station count remains 750 stations per wire path.
3. Each ICI(+) contains a maximum of two (2) IC 2-Wire Driver Boards. Each Driver Board has a
maximum capacity of two (2) wire path outputs.
4. Driver Board maximum capacity is 1,500 stations when both IC wire path outputs are used.
5. The ICI(+) has a maximum capacity of 3,000 stations when all four (4) wire paths are used on
the two (2) Driver Boards.
6. Systems that require more than 3,000 stations will require additional interfaces.
7. The ICI+LINK interface is used to communicate wirelessly with LINK satellite controllers. ICMs
cannot be connected downstream of a LINK satellite controller.
NOTE: LINK communication is not compatible with IC System devices. An ICM must be hardwired
to an ICI+ wire path and cannot be connected through a LINK satellite.
