Each port of the Intelligent System Controller (ports 2-5) can support up to four (4) Star Multiplexers within 1000 feet of the Intelligent System Controller. The Intelligent System Controller ports are not limited to only the Star Multiplexer. The controller is capable of other addressable devices (such as the Input Control Module, Output Control Module, Single Reader Interface Module, or Dual Reader Interface Module) on the same port as the Star Multiplexer. However, the same distance limitation applies.Upstream Host Communication WiringRS-232 2-WIRERS-485 2-WIRETR+TR-GNDTR+ TXDTR+ TXDTR- RXDTR- RXDGNDGNDTxDRxDGNDWire with 24 AWG strandedWire with 24 AWG stranded twisted pair(s) with shieldEarth GroundEarth Ground
