The Atlona AT-HDVS-150-TX is a three-input switcher and HDBaseT transmitter with two HDMI inputs and one VGA input with analogue audio. It is designed to pair with the AT-HDVS-150-RX receiver/scaler (sold separately), carrying video up to 1080p with embedded audio up to 70 m (230 ft) over category cable, and it is powered remotely by that receiver over PoE. It is typically installed in a lectern, under a boardroom table or on a wall in classrooms, huddle rooms and meeting spaces. It switches automatically to whichever source is connected, detecting the HDMI hot-plug signal, and when paired with the HDVS-150-RX it can send RS-232 commands that switch the display on when a laptop is plugged in and off when it is removed; a front-panel button gives manual display on/off and input select. Front LEDs show power and the active input. Surface-mounting brackets are included. It measures 38 x 127 x 102 mm. Atlona lists it as discontinued, with the AT-OME-ST31A as the replacement.
