Overview

The KanexPro EXT-HDMICAS70M cascading HDMI extender distributes 4K@60Hz HDR to up to 10 displays simultaneously — each on its own Cat6 run up to 70M, each independently managing resolution and EDID. Ideal for digital signage networks, multi-room installations, and any environment where the same 4K content must reach many displays.

Scale by adding EXT-HDMICAS70MRX receiver units (sold separately) without additional transmitters. Each receiver auto-adapts to the connected display's native resolution and EDID. Bi-directional IR and ARC S/PDIF included. Backed by KanexPro's 3-year warranty.

Key features
  • Zero latency 4K@60Hz HDR over single Cat6 to 70M — cascade up to 10 additional receivers
  • Supports up to 10 add-on RX units (EXT-HDMICAS70MRX) for multi-display distribution
  • Each receiver independently manages display resolution and EDID — auto-adapt for mixed displays
  • HDCP 2.2 and EDID support
  • Bi-directional IR pass-through 20-60KHz — IR blasters included
  • ARC S/PDIF digital audio de-embedded output
  • Plug-and-play with zero configuration
  • Compact aluminum chassis: 106x99x26.2mm, 210g TX/RX
  • 3-year KanexPro parts and labor warranty

What is the maximum resolution supported?
The EXT-HDMICAS70M is HDMI 2.0 / HDCP 2.2 compliant, supporting up to 4K x 2K @ 60Hz (4:4:4 HDR).
What is the maximum distance per run?
Each receiver connects over a single Cat6, Cat6a, or Cat7 run of up to 70M (230 ft.).
How does EDID management work across multiple displays?
Each RX independently manages its connected display's resolution and EDID, so mixed-resolution environments, such as a 4K monitor paired with a 1080p projector, can run from the same source without manual configuration.
How is the system wired for multiple displays?
Connect the HDMI source to TX HDMI IN, then run individual Cat6 cables from the TX RJ45 OUT ports to each RX unit, up to 70M per run, with the display connected to each RX HDMI OUT.
What cable is required?
A single Cat6, Cat6a, or Cat7 cable per run, STP recommended with proper grounding; keep the Cat cable away from power cables.
What are the unit dimensions and weight?
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.
One display has the wrong resolution. What should I check?
Because each RX manages EDID independently, power-cycle the affected RX with its display connected. The RX will reread the display EDID and adapt.
A cascaded RX is not receiving signal. What should I check?
Verify the Cat6 run to that RX does not exceed 70M, confirm the TX RJ45 OUT port connected to it is active, and check that both TX and the affected RX are powered.
What use case fits the EXT-HDMICAS70M?
It fits one-to-many 4K distribution jobs where a single 4K@60Hz HDR source needs to reach multiple independently managed displays over Cat6 runs, up to 10 total.
How does this differ from the EXT-HDMICAS70MRX?
The EXT-HDMICAS70M is the base kit that includes both the transmitter and a first receiver; the EXT-HDMICAS70MRX is the add-on receiver, sold separately, used to add each additional display up to the 10-display maximum.
