The HDMI Ultra-Slim HDBaseT + RS232 and IR over Cat Extender Box Transmitter - 4K 60Hz allows a 4K HDMI source to be extended up to 130ft to a 4K display using a single Cat6a Ethernet cable. This is an ideal solution where HDMI video and audio need to be extnded to displays in conference rooms, classrooms, lecture halls, and many other installation needs that are far beyond the length limitations of standard HDMI cabling.This transmitter extends HDMI signals over a single network patch cable. Extend 4K HDMI up to 115 feet and 1080p up to 230 feet using a Cat5e or Cat6 cable. For longer 4K distances, extend 4K HDMI or up to 130 feet using a Cat6a cable.This HDMI HDBaseT transmitter is HDCP 2.2 compliant, making sure that the connection from the source is secure. With bi-directional PoC support, one power adapter at either transmitter or receiver side can power both units, so no additional power adapter is required, allowing for greater flexibility in installations. Advanced users can control bi-directional IR and RS232 pass through.

DisplayPort Extender Kit Ideal for Digital Signage in Schools, Restaurants and Lecture HallsThis complete transmitter and receiver system is recommended for video presentations in conference rooms, schools, trade shows, meeting facilities, houses of worship, retail settings, hotels and other digital signage applications where the source and display are farther apart than conventional A/V cables allow.Extends a 4K A/V Transmission up to 230 ft.The B127A-1A1-BDBD extends 4K signals from a DisplayPort source device to a DisplayPort monitor up to 230 feet (70 meters) away via user-supplied Cat6 cabling. By adding a B127A-010-H HDMI repeater or B127A-110-BH transceiver (sold separately) to the application, you can extend the signal up to 400 feet (122 meters) or 460 feet (140 meters), respectively.Transmits Crystal-Clear 4K Video with Multi-Channel Audio and 4:4:4 ColorThe B127A-1A1-BDBD supports Ultra HD resolutions up to 3840 x 2160 (4K x 2K) at 30 Hz with full, rich uncompressed DTS-HD, Dolby TrueHD and 7.1-channel digital audio. HDCP 2.2 compliance allows you to stream 4K Amazon and Netflix content with no complications. This extender kit also supports 4:4:4 chroma subsampling for top-level PC gaming or using your HDTV as a PC monitor. Built-in equalization allows you to fine-tune the image quality at the remote display.Local HDMI Port on Transmitter Supports 4K @ 30 Hz ResolutionTo monitor the video signal being extended to the receiver, connect a 4K display to the transmitter’s local HDMI port with a user-supplied HDMI cable (such as P568- or P569-Series). This port does not support multi-resolution capabilities, so the connected monitor must also support 4K/30 Hz to function properly.Built-In PoC Technology Provides Receiver Power to Avoid Bulky External Power BricksPower over Cable (PoC) technology powers the receiver over Cat6 cable. LEDs on both the transmitter and receiver will light up to indicate the system is receiving power and a signal is being transmitted. PoC lets you avoid the hassle of a bulky power brick and gives you the freedom to place the receiver where needed without worrying about finding a nearby AC outlet.DIP Switch Extends Your Choice of Either USB or IRThe DIP switches on both the transmitter and receiver can be adjusted to let you choose from the USB 1.1 or bi-directional IR functions. Choose to control the source device via keyboard and mouse or IR remote control from the display end of the installation. Only one function can be extended at a time.Plug-and-Play Operation for Quick Setup and Immediate UseThe included transmitter and receiver units work right out of the box with no software required. Mounting hardware is included for installing both units on a wall, pole or 19-inch rack. Connect the transmitter to the source with a user-supplied DisplayPort cable (such as P580-Series). Then, connect the receiver to the display with another user-supplied DisplayPort cable. Finally, connect the two units with user-supplied Cat6 patch cable (such as N202-Series).TAA-Compliant for GSA Schedule PurchasesThe B127A-1A1-BDBD is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.
