The ATUC-VU from Audio-Technica is a voting unit designed for use with the ATUC-50 & ATUC-IR discussion systems for conferencing and educational applications. It plugs into the RJ11 connector on a ATUC-50DUa Discussion Unit (available separately), which also supplies the necessary power. The unit features an NFC card reader and 5 buttons, each with an indicator LED. Votes are collected at the control computer connected to the ATUC-50CU (available separately). If the connected DUa unit is set to priority, specialized functions can be assigned to buttons and indicators via Web Remote.
