Overview

Delivers 4K60 4:4:4 HDR from the rack or lectern to a display or projector up to 40 m (131 ft) away, with power needed at only one end of the run. The kit is a compact black metal transmitter and receiver, each 4.53 x 2.56 x 0.67 in (115 x 65 x 17 mm), linked by a single straight-through CAT6 cable that also carries 1080p to 70 m (230 ft). One 24V/1A adaptor plugged into either unit powers both over the cable, so a ceiling projector or a display above a fireplace needs no outlet. It is the right choice for classrooms, meeting rooms, hospitality venues and residential media rooms where a clean single-display run with full 18Gbps video and control matters more than eARC, USB or Ethernet extension.

The link is HDMI 2.0b at 18Gbps with HDCP 2.2 and 1.4. It passes 10-bit HDR and HBR audio, including Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X, with CEC bypass. Two independent IR channels and bi-directional RS-232 on 3-pin Phoenix connectors share the same cable. A control system at the rack can drive the display, and a handheld remote at the display can still operate the source. Two IR emitter cables and two IR receiver cables are in the box, so both directions work out of the box. Nothing touches the network, so there is no IP addressing to plan and no IT sign-off to wait for. Link and HDCP status lamps on both units show at a glance whether the cable run or the source is the problem. The single strongest differentiator is Power over Cable from either end: the adaptor goes wherever the outlet is, at the source or at the display.

Does the EXT-HDBT18G-70M have an optical (TOSLINK) audio output?
No. The EXT-HDBT18G-70M has no optical audio port and does not support optical audio output. Audio travels embedded in the HDMI signal and passes through to the HDMI Out on the receiver, including HBR formats and LPCM up to 7.1.
Which HDMI and HDCP versions does the EXT-HDBT18G-70M support?
It is HDMI 2.0b compliant with 18Gbps of video bandwidth, and it supports HDCP 2.2 and HDCP 1.4. It is also DVI compliant.
What resolutions, color spaces and color depths does it pass?
It passes up to 4K2K@50/60Hz (YUV 4:4:4), 4K2K@30Hz, 1080p@120Hz and 1080p 3D@60Hz. Supported color spaces are RGB, YCbCr 4:4:4 and YCbCr 4:2:2, at 10-bit or 12-bit color depth.
How does a control system send RS-232 through the extender?
Connect the control system or computer to the 3-pin Phoenix RS-232 connector (TX, GND, RX) on one unit. Connect the device you want to control to the RS-232 connector on the other unit. Serial commands then pass between them over the CAT cable in either direction.
Can IR run in both directions at the same time?
Yes. The kit carries two independent IR channels. Channel 1 runs from the receiver to the transmitter, so you can control the source from the display end. Channel 2 runs from the transmitter to the receiver, so you can control the display from the source end.
What cable do I run between the transmitter and the receiver?
Run a single CAT6 cable with straight-through wiring, terminated to the same standard at both ends. Crossover cables are not supported. If the extender detects a crossover cable it goes into protection mode, and no video reaches the display.
How do I connect the source and the display?
Connect the HDMI source, such as a Blu-ray player or game console, to HDMI In on the transmitter. Connect HDBaseT Out on the transmitter to HDBaseT In on the receiver, then connect HDMI Out on the receiver to the TV or monitor.
There is no picture on the display. What should I check first?
Check that the Power LED is lit on both units. Then look at the Connection Signal lamp: if it is dark, the two units are not linked, so check that the CAT cable is plugged into HDBaseT Out and HDBaseT In and that it is wired straight-through, not crossover. A crossover cable puts the extender into p
The Connection Signal lamp is flashing. What does that mean?
A flashing Connection Signal lamp means the link between the transmitter and the receiver is poor. Check the CAT cable and re-terminate both ends to the same standard. A steady lamp means a good link.
What distances does this kit support?
Up to 40 m (131 ft) at 4K60 4:4:4, and up to 70 m (230 ft) at 1080p60 up to 12-bit (36-bit) colour, over a single CAT6 cable with straight-through wiring. 1080p120, 1080p60 48-bit and 3D 1080p60 are limited to 40 m (131 ft). Crossover cables are not supported. Plan runs over 40 m as 1080p runs.
