RFID multiplexers: AdvanMux-4TM 

advanmux-4-enclosure advanmux-4

AdvanMux-4 features:

  • 4 port multiplexer
  • high performance
  • expands by a factor 4 the number of antennas connected to the same reader
  • compatible with most RFID reader models in the market
  • can be directly connected to AdvanReader-50, AdvanReader-100 or AdvanReader-150 through a conventional Ethernet cable
  • easy selection of ports by sending proper commands to the reader
  • controlled both by standard +5 V and open collector digital outputs
  • powered from +5 V DC to + 48 V DC
  • 2 red LED diodes showing the digital-in status
  • 1 white LED showing the power on status

AdvanMux-4 benefits:

  • reduces the cost of RFID applications with many antennas
  • low insertion loss
  • compatible with most reader models
  • very fast and easy connection
  • easy control of several multiplexers by interconnecting them with standard Ethernet cables
