Speedway GPIO Box

Get convenient access to the reader’s GPIO port

The Speedway GPIO Box is designed for use with the Speedway RAIN RFID reader to provide easier access to the reader’s GPIO (General Purpose Input/Output) port. The GPIO Box interfaces with the reader via a supplied HD15 cable, and separates each input and output signal to easy-access screw terminals. Neighboring ground and power terminals accompany each signal terminal to easily connect three-wire devices. The GPIO Box also includes an on-board relay to interface with devices which require high wattage or an open/short signal.


The GPIO box features

  • Easy-access screw terminals
  • Power and ground terminals for each input and output
  • Each output can provide 250mA at 24V with optional external universal power supply
  • SPDT Relay output capable of 5A at 240VAC
  • Ability to use reader-supplied 5V for low power digital applications, including the SPDT Relay
  • Highly visible LED indicators for each input and output eases troubleshooting and diagnostics
  • Access to reader’s RS-232 serial interface
