The iBright Base unit is and IR (Infrared) transceiver that collects the signals from the H-ITT iBright remotes and sends the data to the computer. It connects to a computer via USB port or to a serial port. There is no limit to the number of IR remotes that can be used, however, for best performance we recommend approximately 35 “seats” for each iBright Base.
*Base includes a 6' USB cable, mini tripod and mounting hardware.
