Front-End Processors



PMC

Providing a scalable front end for StarWatch security systems, the DAQ PMC (Primary Monitor Console) acts as an intelligent data center, processing and storing information collected from remote sensors and devices and sending detailed status reports to multiple operator workstations. Supporting large-scale sensor networks, the PMC provides the capacity to integrate up to 4,095 RADC network controllers into a comprehensive security solution.

  • Powerful data processing and communications modules
  • Instantaneous updates reflecting real-time status of connected sensors and data points
  • Rack-optimized hardware components
  • LAN architecture facilitating multi-tasking, multi-user security environment

 

Poller Mux

Acting as powerful, intermediate data processing hubs in large-scale StarWatch security systems, DAQ Poller Mux modules collect information from multiple RADC network controllers and record selected data in local RAM for periodic polling by the MCU front end computer. This dual-tiered, distributed architecture approach eliminates the need for the MCU to poll individual RADC modules, significantly improving data flow efficiency and simplifying communication connections.

  • Single unit can communicate with up to eight RADC network controllers
  • Two asynchronous communications ports, one for polling of RADC units and one for polling by MCU front end computer
  • Programmable Mux address, bit rates, and request-to-send delays

To accommodate large point counts, a series of Poller Mux modules, configured in any combination of audio or digital communications channels, can be connected to a single MCU.
