The CueStation Universal Network Hub is a multi-purpose interface for controlling button stations that use either 2-Wire or 5-Wire network technologies. The Hub acts as both a power supply for the stations as well as a gateway for allowing host systems to receive button events and instruct the button indicators to illuminate in various ways. The Network Hub is not used with Passive stations. The Network Hub (with optional Ethernet) communicates with the host system by RS-232 and/or Ethernet messages.

Key Features

  • Communicates with the host system via RS-232 and/or Ethernet (optional)
  • Drives both 2-Wire and 5-Wire CueStation networks, which can be used simultaneously
  • Can drive up to (50) 5-wire stations and (10) 2-wire stations
  • Removable terminal blocks
  • Available in low-cost version without Ethernet
  • Available in DIN-Rail version

Included Items

  • CueStation Universal Network Hub
  • Power Supply
  • Mounting Flanges
  • Instructions


  • The 2-Wire CueStation Bus uses a 2-conductor cable to carry both power and data to and from each station location. The network is both topology free (meaning a random combination of “star” and “daisy-chain” connections may be used) and polarity free (meaning it does not matter if the conductors are reversed at any station).
  • The 5-Wire CueStation Bus uses a 5-conductor multi-cable to carry both power and data to and from each station location.
