Safety And
Performance Notice
The transmission distances of HDMI
over UTP cables are measured using TE
CONNECTIVITY 1427071-6
EIA/TIA-568-B termination (T568B) of
cables is recommended for optimal
performance.
To minimise interference of the unshielded twisted pairs in the CAT5e/6
cable do not run the HDBaseT /
Cat5e/6/6a cabling with or in close parallel proximity to mains power cables.
Do not substitute or use any other
power supply other than the enclosed
unit, or a Blustream approved replacement.
Do not disassemble either the Transmission or Receiver units for any
reason. Doing so will void the manufacturer’s warranty.

Audio Breakout
The HMXL44 V2 Matrix includes audio breakout from the selected HDMI input to associated analogue L/R audio and coaxial digital
outputs. Extracted audio will be concurrent with the corresponding HDMI video output.
The HMXL44 V2 analogue outputs include pre-amp line level control allowing you to connect the Blustream matrix directly into a
power amplifier for all your multi-room audio needs.

1. Coaxial digital output - Output 1
2. Analogue pre-amp line level output 3.5mm stereo jack - Output 2
Control of the pre-amp line level outputs is via the matrix front panel, RS-232, TCP/IP or using the in-built web browser interface.
Please see ‘RS-232 & Telnet Commands’ on page 15 for further details.
Note: Volume control is only available on the analogue audio outputs. Source input must be PCM 2ch audio for analogue audio out-
puts to work. The HMXL44 V2 Matrix does not down-mix multi-channel audio signals.
Note: Volume control of audio outputs is not possible via InfraRed control.
It is important that the interconnecting CAT cable between the Blustream HDBaseT products is terminated using the correct RJ45
pin configuration. The link CAT cable MUST be a ‘straight’ (pin-to-pin) CAT cable and it is advised that this is wired to the T568B wiring standard as this format is less prone to EMI (Electro-Magnetic Interference).
When installing CAT cables it is advised that you use the best possible CAT cable quality possible. HDMI distribution products will
only work if used with CAT5e standard cable or above. Blustream recommends using a CAT6 cable for your installations, especially
when running over longer distances, in areas of high EMI, or with 4K signal distribution.

Understanding the RX/HMXL44 V2 HDBaseT status lights
The Blustream HMXL44 V2 Matrix and HDBaseT extender solutions include status LED indicators on both the Matrix and Receiver
products to show all connections are active and to help diagnose possible problems.
Understanding the status lights:-
Blustream HMXL44 V2 Matrix:
• The Yellow HDBaseT status link light will be o when the zone output has been turned o or there is a problem with the
specific Matrix output.
• The Yellow HDBaseT status link light will blink when the zone output is on and working
• The Green HDBaseT link light will blink if there is an unstable connection between the Blustream Matrix and HDBaseT Receiver
• The Green HDBaseT link light will be lit when a there is an active HDBaseT Receiver connected to the Matrix
• The Green HDBaseT link light will be o when a there is no connection with a HDBaseT receiver
Blustream HDBaseT Receiver:
• The HDMI link light will be o when there is no connection with a display
• The HDMI link light will be on when there is an active connection with a display (NOTE - Not all HDBaseT RX feature a HDMI
status LED)
• The HDBaseT link light will be o when there is no CAT cable/active HDBaseT connection on the RJ45 HDBaseT input
• The HDBaseT link light will blink if there is an unstable connection between the Blustream Matrx and HDBaseT receiver
• The HDBaseT link light will be lit when a CAT cable is connected to the HDBaseT RJ45 output on the Matrix and an active
connection is achieved with the Blustream HDBaseT Receiver.

InfraRed (IR) Distribution
The Blustream range of matrix products include multiple options for control and routing of IR.
IMPORTANT: Blustream InfraRed products are all 5V and NOT compatible with alternative manufacturers InfraRed
solutions. When using third party 12V IR control solutions please use supplied Blustream IRCAB cable for IR conversion.
Each Blustream Matrix and HDBaseT receiver is supplied with all necessary IR hardware required and includes:
IR Emitter - IR1 & IR2 (IR2 sold separately)
Blustream 5V IR Emitter designed for discrete IR control of
hardware
IR Receiver - IRR

correspond to the zone outputs 1 - 4)
B Selects the source INPUT you wish
to change on the selected zone
(Numbers 1 - 4 correspond to the
source inputs 1 - 4)
EXAMPLE
To switch source 2 to zone 4 you
would press 4 in the output section

section (B).
ALL button: The all button selects
all the inputs or outputs in its
corresponding box. Example: (The “All”
button in the Output box selects all the
zones so all zones will change to what
source input is selected next)
PTP: This button will align all the zone
outputs with the like numbered source
inputs. Example: Input 1 to output 1,
input 2 to output 2, etc
EDID SET UP
The HMXL44 V2 provides a
comprehensive range of EDID settings.
Below are three examples of how to
deploy the desired EDID setting when
using the supplied remote.
A. Fix EDID to an Input or ALL inputs:
Press the desired video resolution
button (1080i / 1080p / 3D / 4K),
then select the desired audio format
(2.0ch / 5.1ch / 7.1ch), then select
the source input you want this EDID
information allocated to by pressing
the INPUT 1 – 4 or the ALL button
B. Copy EDID of Output-X to an Input
or ALL: Press the COPY but-ton then
select the OUTPUT you wish to copy
the EDID information from, then
select the source input you want to
copy this EDID to by selecting the
INPUT 1-4 or the ALL button.
C.User defined EDID to an Input or
ALL inputs: Press USER1 / USER2
button then select the source you
wish to assign this EDID to by selecting INPUT 1-4 or the ALL button
NOTE: THE BUTTON PRESS SEQUENCE SHOULD BE FINISHED IN 5 SECONDS,
OTHERWISE THE OPERATION IS DISCARDED

EDID Control
EDID (Extended Display Identification Data) is a data structure that is used between a display and a source. This
data is used by the source to find out what audio and video resolutions are supported by the display then from this
information the source will discover what the best audio and video resolutions need to be outputted.
While the objective of EDID is to make connecting a digital display to a source a simple plug and play procedure
issues do arise when multiple displays or video matrix switching is introduced because of the increased number of
variables.
By pre-determining the video resolution and audio format of the source and display device you can reduce the time
need for EDID hand shaking thus making switching quicker and more reliable.
Configuration of Matrix EDID settings can be acheived in one of five ways:-
1 Using Matrix PC Soware (See ‘Blustream Matrix Soware Guide’ for further details available at www.
blustream.co.uk)
2 Using Matrix web browser interface (See ‘Blustream Web Browser Interface Guide’ for further details
available at www.blustream.co.uk )
3 Using Matrix Front Panel Buttons (For further details see page 7)
4 Using Supplied Blustream Matrix IR Remote Control (For further details see page 10)
5 Using dip-switches on the rear panel of the HMXL44 V2 Matrix. Please see below table for global EDID settings.
*Note - Once dip-switch settings have been made the HMXL44 V2 should be power cycled for settings to be
applied.
The Blustream HMXL44 V2 can be controlled via serial and TCP/IP. The following pages list all available serial commands for the HMXL44-V2 Matrix. Details of RS232 pin assignment can be found on page 05.
Commonly used Serial commands:
There are several commands that are commonly used for control and testing:-
STATUSStatus will give feedback on Matrix such as zones on, type of connection etcPONPower onPOFFPower oOUTxxON(xx is the zone number you wish to turn on)
Example:- OUT01ON (This would turn output one back on)OUTxxFRyy(xx is the zone out, yy is the input)Example:- OUT01FR04 (This would switch output 1 to source input 4)
Common Mistakes
• Carriage return – Some programs do not require the carriage return where as other will not work unless sent directly aer the string. In the case of some Terminal soware the token <CR> is used to execute a carriage return. Depending on the program you are using this token maybe dierent. Some other examples that other control systems deploy include \r or 0D (in hex)
• Spaces – Blustream commands do not require space between commands unless specified. There may be some programs that require spacing in order to work.
- How the string should look is as follows OUT01ON
- How the string may look if spaces are required: OUT{Space}01{Space}ON
• Baud rate or other serial protocol settings not correct - please see Page 5 for Matrix settings
