HDMI-TPS-TX87 Twisted pair HDBaseTTM extenders provide extension of uncompressed 4K/UHD video with embedded audio (up to eight channel PCM or HBR audio) for long distances over a single CATx cable. The unit offers bi-directional RS-232, IR pass-through on the same CATx cable that carries the video signal. The TPS extenders support full HDCP and EDID compliance and work on all standard AV resolutions up to 4K and 48-bit color depth handling all standard audio formats and also 120 Hz 3D signals. PoE 48V remote powering is available through a single CATx cable, but a local power supply can also be used. All devices can be mounted on a rack shelf or used standalone. The auto operation mode allows the device to detect the far end extender’s mode and adopt it. If the far end device is in Auto mode or it is a third party HDBaseTTM device the link will be set to HDBT mode. If the far device is in forced Long Reach Mode then the auto operation will set the Link to Long Reach Mode. The IR OUT can operate in either Wired (unmodulated) or Emitter (modulated) mode. HDMI-TPS-TX87 compatible with HDBaseT extenders and matrix switchers.
