1.0 Introduction
The ECHO family is a series of extension products designed to allow a single
HDMI 2.0 source to display remotely at up to eight different locations, using
HDBaseT technology. HDMI resolutions up to 4K UHD (4K@60 4:4:4) can be
extended up to 70m, while resolutions up to 1080p can be extended 100m over
a single CAT5e or CAT6 cable. The ECHO family supports HDCP 2.2 and 1.4
content protection, as well as HDR10 high dynamic range video.
In addition to HDMI extension, the ECHO family also extends RS-232 serial data,
and bi-directional IR for control of remote devices. All senders include a local
HDMI output, EDID routing control, de-embedded analog audio, and Power over
Cable (PoC) to power remote receivers. The ECHO-4S and ECHO-8S have built-
in HDMI splitters to extend a single video to four and eight receivers
respectively and have additional features including RS-232 and IR loop output
for daisy-chaining Senders, and digital TOSLINK audio de-embedding.
The ECHO-RX2 receiver has a built-in HDMI splitter for connection to a
secondary display, RS-232 and bi-directional IR for control, and de-embedded
analog audio output. When used with an ECHO-1S, install the power supply at
either sender or receiver – whichever is more convenient.

Installation
 Connect the HDMI source (Blu-ray, PC, media player, etc.) to the HDMI IN
port on the sender.
 Optionally, connect the HDMI OUT to a local display.
 Connect the HDBaseT output(s) of the sender to HDBaseT Input(s) of the
receiver(s). Ensure the cables do not exceed 70m for 4K or 100m for
1080p video.
 Connect the HDMI OUT1 and/or OUT2 of the receiver to a compatible
display.
 Connect power to the sender. (For ECHO-8S, use 24 V 2 A supply for main
power, and 24 V 4 A supply for PoC power.)
 Optionally, connect Audio Out at the sender or receiver to an external
audio amplifier or sound reinforcement system.
 Optionally, connect the RS-232 or IR detectors and emitters to allow for
remote control of the displays or other compatible peripherals. See
Section 5 below for more information about RS-232 commands.
EDID Routing and Emulation
Each ECHO sender has a three-position switch to control which EDID is
presented to the video source: Local, Remote, or EMUL (emulate).
 Local: Use the EDID of the display attached to the local HDMI OUT port.
 Remote: Use the EDID of the display attached to the Receiver. For
ECHO-4S and 8S, the Sender will check the first HDBaseT Output, then
the second, and so on. If there are no displays attached, it will use an
emulated EDID that is stored in the ECHO-RX2 Receiver.
 EMUL: Use an emulated EDID stored in the Sender.
NOTE When using the ECHO-1S with ECHO-RX2, install the power
supply at either the sender or receiver, whichever is more
convenient. When using the ECHO-4S or ECHO-8S, install
the power supply at the sender side only, and all of the
receivers receive power via PoC.
DO NOT apply power to receivers
when using ECHO-4S or ECHO-8S.

Connecting multiple senders – Daisy-chain
Daisy-chaining Audio and Video
To extend video to more than eight remote displays, additional senders can be
daisy-chained together using the HDMI IN and HDMI OUT connectors.
The ECHO-4S and ECHO-8S support daisy-chaining of up to eight senders;
totaling up to 64 possible remote displays.
To daisy-chain the HDMI source, use quality
HDMI cables to connect HDMI OUT of the
first box to HDMI IN of the second.
Hall Research carries a line of SnugFit™
HDMI cables designed for HDMI 2.0 and
featuring locking tabs to more securely affix
the HDMI cable in the connectors.
Daisy-chaining RS-232 (ECHO-4S and ECHO-8S)
By default, RS-232 sends all characters received by the 1st ECHO-x RS-232 input
to all RS-232 outputs at each receiver and RS-232 Loop Output.
If certain RS-232 outputs in the daisy-chain require unique commands, then
each sender must be assigned a unique device ID (from 1 to 8).
This ensures that every HDBaseT Output has a unique address for connecting
and routing serial commands. See Section 5 below for information on setting
Device IDs.
To daisy-chain the RS-232; connect the RS-232 Loop of the first Sender to the
RS-232 In of the second, and so on.
RX Loop connects to TX In, TX Loop connects to RX In, and GND connects to GND
as shown:

Daisy-chaining IR (ECHO-4S and ECHO-8S)
To daisy-chain IR, use the supplied 3.5mm cables to connect the IR Loop Out of
the first sender to the IR In of the second, and the IR Loop In of the first sender
to the IR Out of the second, as shown:

5.0 Serial RS-232 Control
The ECHO-4S and ECHO-8S senders use system commands to select which
HDBaseT output to route the RS-232. Before daisy-chaining multiple senders,
assign a unique Device ID to each one by issuing an RS-232 system command to
each sender.
Serial Communication Parameters
Baud rate: 115200, Bits: 8, Parity: None, Stop bits: 1, Flow Control: None
Serial Commands
 System commands start with the “#” character and terminate with a
carriage return and line feed <CR><LF>.
 System Commands must be sent as a complete string without any delay
between characters.
 All responses from connected receivers are output on a first-come-first-
served basis.
 Do NOT send the ‘[‘ and ‘]’ characters

6.0 Troubleshooting
If you are experiencing problems getting the ECHO to work properly, please use
the following troubleshooting suggestions.
 Ensure the CATx cables do not exceed 70 m for 4K video, or 100 m for
1080p video in length.
The use of RJ45 couplers not recommended.
Substitute a shorter length or known-good cable to test the output port
or receiver.
 Ensure the proper power supplies are used on each device:
o ECHO-1S uses a 24 V 1 A supply.
o ECHO-4S uses a 24 V 4 A supply.
o ECHO-8S uses a 24 V 2 A supply for main power, and 24 V 4 A
supply for receiver PoC power.
o ECHO-RX2 does not use a power supply unless paired with
ECHO-1S ONLY. Use a 24 V 1 A supply.
 Check the EDID routing.
For example, if the ECHO-RX2 is receiving a 4K signal, but some of the
monitors are 1080P; those monitors may not display an image.
Change the EDID routing to read the EDID from the 1080P display, or
whatever resolution is the highest common denominator.
 Try resetting the system by unplugging the power supply, waiting 5
seconds, and plugging it back.
Alternately, press and hold the RST button for 3 seconds to reset to
Factory Default.
(The sender Device IDs MUST BE reprogrammed if used in a daisy-
chain configuration.)
Contacting Hall Research
If you determine that your ECHO sender or receiver is malfunctioning, do not
attempt to repair the unit.
There are no user-serviceable parts inside, and you will void your warranty.
Instead, contact Hall Research Technical Support at 714-641-6607. To return
the unit to Hall Research you must first get a Return Authorization (RMA)
number.
Package the unit carefully, if returning. We recommend that you use the original
container.
