QSB Quadrature To USB Adapter

---

QSB Quadrature To USB Adapter is a low cost USB data acquisition device that can count quadrature and index signals from an incremental encoder, provide digital I/O, perform A/D conversion or act as a stepper/motor controller. There are 4 variants that provide a mix of different features.

• QSB-S - One single-ended quadrature encoder interface
• QSB-M - One single-ended encoder interface and either 4-bits of digital I/O or 1 channel step/direction stepper motor control and 2-bits of digital I/O
• QSB-I - Four 10-bit A/D inputs and either 4-bits of digital I/O or 1 channel step/direction stepper motor control and 2-bits of digital I/O
• QSB-D - One differential quadrature encoder interface and 1-bit of digital I/O

The QSB is USB bus powered and is packaged in a slim, compact "stick" package that it is easy to install and wire up. US Digital provides a CD with all the software and documentation needed to use the QSB. A PC demo application is included, allowing the user to confgure and explore various features of the QSB using a graphical user interface. A library with a detailed Application Programming Interface is provided so that users can develop their own applications; additionally, the CD provides several examples that demonstrate how to use the device. For users that prefer lower level control, a register based interface and documentation is also provided. 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 as well.
