QSB Product Description

Restriction of Hazardous Substances

The QSB is a low-cost USB data acquisition device. The QSB-S and QSB-D count quadrature and index signals from incremental, PWM, and analog encoders. The QSB-M provides digital I/O and acts as a 1-channel stepper/motor controller.

  • QSB-S - One single-ended quadrature, PWM, or Analog encoder interface
  • QSB-D - One differential quadrature, PWM or Analog encoder interface and 1-bit of digital I/O
  • QSB-M - One single-ended quadrature, PWM or Analog encoder interface; 4-bits of digital I/O or 2-bits of digital I/O and 1-channel stepper motor control (step/direction)

The QSB plugs into any USB (Type A) port on a Windows or Linux machine and is bus-powered. US Digital provides free software, examples, and documentation needed to use the QSB. The QSB appears as a COM serial port to the PC, so any application that can read/write the COM port can be used to control the QSB.

The QSB-S and QSB-D can be used with the “QuickCheck” app to verify the CPR of an encoder with index quickly.
