Rui Communication - Simplex 4100ES Installation Manual

Like the standalone system, only one CPU is used. Remote Unit Interface (RUI) data and power is distributed from the host panel to remote
boxes called transponder cabinets:
• 4100ES: Transponder interface cards (TICs), located in transponder cabinets, take the RUI data and power directly from the CPU
motherboard and distribute it to modules nearby, thereby expanding the system's status from standalone to MINIPLEX.
• Legacy 4100: Remote interface cards (RICs), located in transponder cabinets, take the RUI data and power from the remote unit
interface (RUI) card in the host panel and distribute it to modules nearby, thereby expanding the system's status from standalone to
MINIPLEX.
4.3.1 System design
The MINIPLEX 4100ES FACU must contain the following:
• CPU
• Power: ES PS for the 4100ES (System Power Supply for the 4100ES , Universal Power Supply for 4100 Legacy Upgrade)
• Legacy 4100 only (non-4100ES/4100U): Remote unit interface (RUI) Card
• Optional cards
Each transponder cabinet, meanwhile, must contain a Transponder Interface Card (TIC) and any number of optional cards.

4.3.2

RUI communication

Data to and from the CPU may have to be routed over long distances in a MINIPLEX system. An RUI line, routed from either the CPU
motherboard in the 4100ES or the RUI card in some legacy systems, allows the data to travel longer distances. Once the RUI line
terminates at a remote box, the TIC (4100ES) or RIC (Legacy 4100) at that box distributes the CPU's data to the remote modules.
Figure 2 outlines this process in a typical 4100ES MINIPLEX setup.
