About KD-EXWPSTX

Key Digital® KD-EXWPSTx is a single-gang wall-plate transmitter + presentation switcher with one HDMI and one USB-C input ideal for professional video installation in conference rooms, huddle spaces, classrooms, and more. KD- EXWPSTx utilizes Key Digital’s proprietary UHDoTP extension technology and is natively received by KD-EX18GRx black box receiver (sold separately). Future Key Digital product releases will include built-in UHDoTP Rx for integration with KD-EXWPSTx. KD-EXWPSTx supports 4K/UHD resolution with bandwidth up to 18Gbps and HDCP2.2 compliancy. KD-EXWPSTx extends video resolutions up to 4096×2160 at 60hz with 4:4:4 chroma sub-sampling over a single CAT5e/6 cable up to 115ft (35m). 1080p signals are extended up to 164ft (50m). In addition to HDMI video and audio signals, KD-EXWPSTX features an IR sensor on the face of the plate to carry IR for controlling remotely located equipment. KD- EXWPSTX is configured using the USB connection and KDMS Pro software to apply settings like 4K to 1080p down convert, EDID handshake control, and hot plug detection for overcoming common systems integration obstacles. The wall-plate unit fits in a standard US single-gang box and is powered by the Rx unit for convenient installation.
