HDBaseT Compact Extender Set 70m with ARC User Guide 1
Introduction
The extender set (p/n CM-BT20-COMPACT-70) consists of a transmitter and receiver
pair. HDMI signals are input into the transmitter and HDBaseT technology is used to
transmit the signals to the receiver up to 230 ft. (70 m) via a Cat5e/Cat6 cable. The
receiver then outputs the HDMI signal.
Bi-directional IR is also transmitted across the Cat5e/Cat6 cable. The extender set
supports ARC (audio return channel), IR control, and PoH (Power Over HDBaseT),
which can be used to power the receiver via the Cat5e/Cat6 cable. This eliminates the
need for power at the receiver end.
Features
 Supports full HD: Delivers high-resolution images (1080p at 60Hz, 3D,
4Kx2K at 30Hz)
 Maximum transmission distance is 230 ft. (70m) for 1080p or 131 ft. (40m) for
4Kx2K over a CAT5e/CAT6 cable
Note: When using ARC, the maximum transmission distance is 131 ft (40m).
 High bandwidth: 10.2 Gbps
 HDTV compatible: Uses HDMI 1.4 and is HDCP-2.2 compliant
 Supports PoH, bi-directional IR, and ARC
 Uses HDBaseT technology for extended capability and reliability
 LED indicators show working status to aid in troubleshooting
 Wall or table mount steel enclosure
Package contents
 1 x CM-BT20-COMPACT-70-TX
 1 x CM-BT20-COMPACT-70-RX

System connection
Usage precautions
 The system should be installed in a clean environment and have proper
temperature and humidity controls.
 All of the power switches, plugs, sockets, and power cords should be insulated for
safety.
 All devices should be connected before powering on.
 The Cat5e/Cat6 terminations for HDBaseT devices must be a straight-thru TIA/EIA
T568B standard.
Application examples
The HDBaseT CM-BT20-COMPACT-70-RX receiver works in conjunction with the
HDBaseT CM-BT20-COMPACT-70-TX transmitter. By transmitting signals across
reliable Cat5e/Cat6 cables, the video signal can be used at far greater distances from
the source device than would be capable with traditional HDMI cables. Additionally,
control signals can be sent bi-directionally across the same Cat5e/Cat6 cable. The
following figures show you some application examples for the HDBaseT CM-BT20-
COMPACT-70-TX and RX.
Note: When using a control system, such as Clare Controls, Crestron, or URC, the
3.5mm male mono to 3.5mm male stereo adapter cable (included) must be used. The
male mono end connects to the control system; the male stereo end connects to
CM-BT20-COMPACT-70-TX.
Figure 4: System connection

Connection procedure
To connect the HDBaseT Compact Extender Set 70m:
1. Connect HDMI from the source (such as Blu-ray) to the HDMI IN port of the
transmitter using an HDMI cable.
2. Connect the HDBT OUT port of the HDBaseT CM-BT20-COMPACT-70-TX to the
HDBT IN port of the receiver with a single CAT5e/CAT6 cable using TIA/EIA
T568B terminations at each end.
3. Connect the HDMI OUT port of the HDBaseT CM-BT20-COMPACT-70-RX to an
HDMI in port on the display using an HDMI cable.
4. When using the bi-directional IR control, do the following.
a. Connect the IR emitter at either end to the IR TX port on the HDBaseT
CM-BT20-COMPACT-70-TX or RX.
b. When using a powered IR receiver, connect via a 3.5mm stereo plug to the
IR RX on either the HDBaseT CM-BT20-COMPACT-70-TX or RX.
5. Connect the 12 VDC power adapter to the power port on the
HDBaseT CM-BT20-COMPACT-70-TX transmitter. The HDBaseT
CM-BT20-COMPACT-70-RX receiver is powered through PoH.
PoH
The CM-BT20-COMPACT-70 supports PoH. Connect the DC adapter to either
CM-BT20-COMPACT-70-TX or RX for power.
Figure 5: PoH connection

6 HDBaseT Compact Extender Set 70m with ARC User Guide
ARC
The coax audio and HDMI ports have an ARC (Audio Return Channel) function. When
enabled, audio is returned from the connected device in the RX to the HDMI or digital
coax out on the TX.
The CM-BT20-COMPACT-70-TX provides an ARC switcher on the bottom panel to
set/change ARC mode selection. For ARC options, see the Table 1.
Table 1: ARC modes
Image
ARC Mode
Description
00
This mode sends ARC through HDMI.
Notes
 This mode limits the transmitting distance.
 The display device must support ARC.
 Both the display device and AVR must have ARC
enabled.
01
Mode 01 is reserved for future use.
10
This mode removes ARC from the HDMI and sends the audio
through digital coax.
11
Mode 11 is reserved for future use.

8 HDBaseT Compact Extender Set 70m with ARC User Guide
Application
The HDBaseT extender pair is useful in any scenario when an HDMI signal (along with
control signals) must be transmitted reliably across greater distances than is practical
using traditional HDMI cables. They may be used in both residential and commercial
applications when centrally locating the source equipment and displaying HD video in
remote locations.
Twisted pair cable connection
The Cat5e/Cat6 terminations for HDBaseT devices should be a straight thru
TIA/EIA T568B standard. TIA/EIA T568A standard is NOT recommended.
