Wireless Data Transmission

The Arrowvale Wireless Serial Adapter (WSA) range of products provide an effective rail approved solution for data acquisition & transmission from isolated or normally inaccessible vehicle equipment. Through a series of 868MHz transceivers, a wireless relay or mesh can be formed enabling data to be transmitted back to a central unit for local or remote collection. The WSA products complement the Arrowvale range of data recorders, remote condition monitoring hardware and the Diagnostyx web based analysis and reporting tool.

Typical applications for data acquisition:

  • OTMR, TMS, HVAC controller, toilet controller, door controller, engine sensors, battery charger, auxiliary power converter, brake controllers etc. via communications ports
  • 3rd party equipment LED light activity when used in conjunction with the Arrowvale LED1000
  • Digital battery referenced train wires, signals and relay contacts
  • A range of volt free contacts, limit/ proximity/ hall effect switches
  • Analogue probes & sensors – speed, temperature, pressure etc.
  • Frequency or counter signals - engine revs, door operations, timings

The WSA can also be used as a data network extender:

  • Outlying data gathering hub
  • Serial port extender incorporating standards conversion
  • Serial to Ethernet extender/ converter
  • Low speed Ethernet jumper between vehicles

Main features:

  • Modular with a variety of optional at-build hardware configuration options
  • User configurable for site specific features
  • High penetration wireless technology. Suitable for cab back-walls, seats or body underframes (subject to survey)
  • Rugged and reliable, built to Rail standards including RIA12 transients
