Overview
The KanexPro EXT-HD50C is a compact HDMI extender transmitter-receiver kit that extends HD signals up to 70 meters (230 ft.) at 1080p, or 40 meters at 4K@30Hz, over a single Cat5e/6 cable. The transmitter includes an HDMI loop-out for local monitoring or cascading to additional extender units.
A selectable EDID copy function lets the TX read EDID from either the local loop-out display or the remote receiver display, ensuring the source always outputs at the correct resolution. Dolby TrueHD, DTS-HD Master Audio, and PCM 7.1 audio pass-through are supported. Bi-directional IR control with included blaster kits, ultra-slim 16.5mm chassis, and KanexPro's 3-year warranty complete the package.
Applications: Digital signage, conference rooms, education, healthcare, residential multi-room, and cascaded multi-display installations.

What is the maximum resolution and bandwidth of the EXT-HD50C?
The EXT-HD50C is HDMI 1.4 / HDCP 1.4 compliant with 10.2Gbps bandwidth, supporting up to 4K@30Hz (4:2:0) or 1080p@60Hz.
What are the maximum distances by cable and resolution?
Over Cat6: 70M (230 ft.) at 1080p@60Hz or 40M (131 ft.) at 4K@30Hz. Over Cat5e: 60M (197 ft.) at 1080p@60Hz or 35M (115 ft.) at 4K@30Hz.
How does the HDMI loop-out support cascading?
The TX HDMI LOOP OUT can drive a local confidence monitor or connect to a second EXT-HD50C TX to extend to additional rooms.
How do I select the correct EDID mode?
Use the EDID mode switch on the TX to choose Local (reads the loop-out display EDID) or Remote (reads the RX display EDID), then power-cycle both units to apply the change.
What cable is required?
Cat5e or Cat6 cable, STP recommended with proper grounding; do not exceed the maximum distance for the resolution in use, and keep the cable away from power lines.
What are the unit dimensions and weight?
The TX and RX chassis measures 3.13 x 2.72 x 0.65 in (79.5 x 69 x 16.5mm); TX weighs 0.29 lb (132g) and RX weighs 0.29 lb (130g).
Image quality is degraded or there is no signal at maximum distance. What should I check?
Use Cat6 STP with proper grounding, avoid parallel runs with power cables, verify connectors are fully seated, reduce cable length if possible, and try switching EDID mode.
The source outputs the wrong resolution. What should I check?
Switch the EDID mode on the TX to match the target display: Remote reads the RX display EDID, Local reads the loop-out display EDID. Power-cycle both units after changing.
What installs is the EXT-HD50C suited for?
Its dual reach of 70M at 1080p or 40M at 4K@30Hz over Cat6, plus a loop-out for local monitoring or cascading to a second unit, fits multi-room or long-run installs where extended distance matters more than native 4K reach.
Why does distance vary by resolution and cable grade?
The higher-bandwidth 4K@30Hz signal degrades over distance faster than 1080p, so reach drops from 70M/60M (1080p, Cat6/Cat5e) to 40M/35M (4K@30Hz, Cat6/Cat5e); choosing Cat6 over Cat5e extends both figures.
