What cable is required and how should it be run?
Use a single Cat6, Cat6a, or Cat7 cable, STP recommended with proper grounding. Do not bundle the Cat cable with power cables, and do not exceed 70M.
What application is the EXT-4KHD70M designed for?
It is a plug-and-play point-to-point HDMI extender for pushing 4K@60Hz HDR content up to 70M over a single Cat6/6a/7 cable, with bi-directional IR and de-embedded ARC audio for a source-to-display run that needs zero configuration.
What is the maximum resolution and HDCP compliance of the EXT-4KHD70M?
The EXT-4KHD70M supports HDMI 2.0 with HDCP 2.2 and passes 4K x 2K @ 60Hz video in 4:4:4 chroma with HDR. Supported resolutions include 480i/p, 576i/p, 720p, 1080i/p, 3840x2160 at 24/25/30/50/60Hz, and 4096x2160 at 24/25Hz.
What is the maximum transmission distance for 4K@60Hz?
The unit transmits 4K@60Hz HDR up to 70M (230 ft.) over a single Cat6, Cat6a, or Cat7 cable.
How is the extender wired into an AV system?
Connect the HDMI source to TX HDMI IN, run a single Cat6/6a/7 cable from TX RJ45 OUT to RX RJ45 IN (up to 70M), and connect the display to RX HDMI OUT. EDID and HDCP negotiate automatically with no configuration required.
How is bi-directional IR control set up?
Connect the included IR blasters to TX IR OUT and RX IR OUT, and use the IR IN jacks as sensors, to enable remote control between the source and display ends.
What are the unit dimensions and weight?
Both TX and RX are housed in a 4.17 x 3.90 x 1.03 in (106 x 99 x 26.2mm) aluminum chassis weighing 0.46 lb (210g) each.
There is no video on the display. What should I check?
Verify the Cat6 cable is securely connected at both ends and does not exceed 70M, confirm Cat6a or Cat7 STP is used, try a different HDMI cable between the source and TX, and power-cycle both units.
IR control is not working. What should I check?
Confirm the IR blasters are pointing at the correct device, verify the IR sensors have clear line of sight, and check that the 3.5mm connectors are fully seated in the IR IN/OUT jacks.
How much setup time does the EXT-4KHD70M add to a job?
None beyond cabling. EDID and HDCP negotiate automatically, so the kit is plug-and-play with zero configuration required.
