4K30Hz HDBaseT HDMI Extender over Cat5e/6 with PoC - 70M
EXT-HDBT70C HDBaseT HDMI extender kit sends 4K30 to 40m and 1080p to 70m over one Cat5e/6, with PoC, bi-directional IR and RS-232, and HDCP 2.2.
The EXT-HDBT70C carries one HDMI source to a distant display over a single Cat5e/6 run, and powers the far end across the same cable — no outlet, no second power brick behind the screen. The kit pairs a transmitter and a receiver in a compact black metal enclosure with mounting ears, driving 1080p to 70 meters and 4K2K@30Hz 4:4:4 to 40 meters over HDBaseT at 10.2 Gbps. Power Over Cable feeds both units from one 12V/1A supply connected at either end, which makes this the right choice for classrooms, huddle rooms, digital-signage endpoints and single-zone residential displays where reach, single-cable installation and embedded control matter more than 4K60 or HDR bandwidth the job never uses. Bi-directional IR and bi-directional RS-232 pass-through travel inside the same cable as the video, so the far-end display can be switched, powered and volume-adjusted and the head-end source controlled from the remote room, all without pulling a separate control run. The link is HDCP 2.2 compliant for protected 4K sources and built to HDMI 1.4, with ESD-protected ports and status indicators for HDCP state and transmitter-to-receiver link quality. The single strongest advantage is spec-right economy: full HDBaseT transport with PoC, IR and RS-232 control delivered at a 4K30 design ceiling, so integrators standardizing many small rooms are not forced to overbuy an 18 Gbps link.
- HDCP 2.2 compliant.
- Supports video resolution up to 4K2K@30Hz, as specified in HDMI 1.4.
- Supports 10.2 Gbps video bandwidth.
- Maximum transmission distance over a single Cat5e/6 cable: 70 meters for 1080p@60Hz/36-bit and 3D 1080p@30Hz/36-bit; 40 meters for 1080p@60Hz/48-bit, 1080p@120Hz/24-bit, 3D 1080p@60Hz/36-bit, and 4K2K
- Supports PoC (Power Over Cable): connect a 12V/1A power supply to either the transmitter or the receiver, and the other unit does not require its own power supply.
- Bi-directional IR and RS-232 control-signal pass-through.
- ESD protection to IEC 61000-4-2: ±8 kV air-gap discharge, ±4 kV contact discharge.
- Data and connection status indicators report HDCP state and transmitter-to-receiver link quality.
- Compact black metal enclosure with mounting ears for flexible installation behind a display or in a rack.

Questions
- Will it do 4K60 or HDR?
- No. It is built to HDMI 1.4 / 10.2 Gbps, so the ceiling is 4K2K@30Hz 4:4:4 (and 1080p up to 60/120 Hz). For 4K60 or HDR, step up to the KanexPro 4K60 extender line. This unit is priced deliberately for jobs that top out at 4K30.
- Can the EXT-HDBT70C be paired with an existing HDBASE70POER transmitter or receiver?
- Not recommended. Compatibility is not confirmed, and the EXT-HDBT70C's HDBaseT port always outputs 24V PoC, which cannot be turned off and could damage the HDBASE70POER. To replace an HDBASE70POE-series setup, use the EXT-HDBT70C kit at both ends.
- What HDMI and HDCP versions does the EXT-HDBT70C comply with?
- The EXT-HDBT70C is HDMI 1.4 and HDCP 2.2 compliant.
- What video bandwidth does the EXT-HDBT70C support?
- It supports 10.2 Gbps of video bandwidth, with resolutions up to 4K2K@30Hz 4:4:4.
- What control protocols does the EXT-HDBT70C pass through a system?
- It provides bi-directional IR and bi-directional RS-232 pass-through alongside the HDMI signal, all over the single Cat5e/6 link.
- How do I wire a control system for RS-232 through the EXT-HDBT70C?
- Connect the control system or PC to the RS-232 port using the supplied 3-pin phoenix connector, and set the RS-232 Mode switch to Ctrl for pass-through control.
- What cable connects the two EXT-HDBT70C units and how do the ports match up?
- Run a single Cat5e/6 cable from the transmitter's HDBaseT Out (RJ45) to the receiver's HDBaseT In (RJ45).
- What plugs into the HDMI ports of the EXT-HDBT70C?
- Connect the HDMI source device to the transmitter's In port and the HDMI display to the receiver's Out port, both HDMI Type A 19-pin female.
- The display shows no picture through the EXT-HDBT70C. What should I check?
- Check the green Data Signal Indicator: off means no HDMI signal, so confirm the source is connected to the transmitter's In port. Then check the yellow Connection Signal Indicator is steady, which confirms the transmitter and receiver are well connected over the Cat5e/6 cable.
- The picture is dropping out or unstable on the EXT-HDBT70C. What should I check?
- A flashing yellow Connection Signal Indicator means the transmitter and receiver are poorly connected, so check the Cat5e/6 cable and its termination. Also confirm the run is within limits: 4K2K@30Hz is supported only up to 40 m, while 1080p runs up to 70 m.
