3.0 PLANNING A MATRIX SYSTEM
• Before installation, test the equipment for compatibility.
Temporarily connect all of the sources, audio receivers,
and displays to the matrix using short HDMI cables
to verify basic compatibility and function. If any
incompatibilities occur, connect the source and display
or audio receiver without the matrix in the signal path for
further HDMI troubleshooting.
• Since all of the displays connected to a particular source
will be receiving the same video signal resolution and
format (e.g. 1080p@60Hz) produced by the source,
make sure the source is set up to output the highest
resolution that all of the displays can accept. For
instance, if one display can accept a maximum input
resolution of 720p, all of the sources are limited to
720p output, and all displays will receive a maximum
resolution of 720p. This consideration is particularly
important if the TVs have a wide range of resolution
capabilities because the highest resolution sets may not
be allowed to perform to their best advantage.
• HDMI cable lengths should be kept as short as
possible. Use the Cat 5 output for cable runs over 50
feet. High resolution settings, refresh rate, and/or deep
color require increased bandwidth, and may effect the
maximum cable run length that can be achieved.
4.0 CONNECTING THE HARDWARE
• Turn off equipment that will be connected to the matrix.
Mount the matrix in an equipment rack if desired, using
the included rack ears. Otherwise, place the matrix on a
at surface with adequate ventilation and access to the
front and rear panels.
• Connect a high quality HDMI cable from each HDMI
source to an input of the matrix. Cable lengths should be
kept as short as possible.
• Connect the outputs of the matrix to their destination
devices using HDMI cables OR dual Cat 5 cables at
each output – both types of output ports may not be
used at once. Use 1380R Cat 5 zone receivers where
cable lengths of 50 feet* or more are required. Either
TIA/EIA 568A or 568B standards may be used provided
it is straight through and not crossover. HDMI cables
perform differently depending on quality of cable and the
source equipment used.
• Connect the power adapter to an AC outlet and then to
the matrix.
• If you are using the RS-232 control function, connect a
standard serial cable from the controller to the HMX-244
RS-232 port.
• Turn on the HDMI sources and displays. Turn on the
matrix and after a pause for HDCP handshaking,
observe the source signals on the displays. The
HMX-244 front panel LEDs light, indicating the active
sources in each zone.
* Proper function of HDMI matrix routers and distribution
systems depends on the use of high quality HDMI cables
with low loss, high bandwidth signal handling capabilities.
The distance specication cannot be guaranteed unless
cables used throughout the system meet these high
standards.
GETTING THE BEST RESULTS USING HDMI
Many factors inuence the performance of an HDMI switching system. Consider the following precautions to
ensure the best system performance.
• Resolutiontracking. Refer to 3.0 “Planning a Matrix System” Set up the sources to output the best resolution
that all TVs can accept.
• Sourceresolutionandvideo/soundquality.Sources, such as satellite receivers or cable boxes may output
at lower resolutions or deliver extremely compressed video material, yielding poor results. Consider the
sources when planning and troubleshooting your system.
• Outputdisplaydevices. The quality of the output signal depends largely upon the type and quality of the
HDMI display devices used.
• Connectioncables. HDMI cable design and quality are extremely important in long cable runs where
capacitance can severely degrade performance. Use premium cables; low quality cables are susceptible to
interference. Always use good strain relief methods to prevent cables from becoming loose over time.
• Distancebetweenthesourcesandthedisplays. Using premium quality cables the sources may be located
up to 20m from the matrix, and the matrix may be up to 15m from each display device. Longer distances are
possible using advanced HDMI extenders with DDC correction.
• Interference.Nearby electrical devices can negatively affect signal quality. For example, older computer
monitors often emit strong electromagnetic elds that can interfere with the performance of adjacent video
equipment.

6.0 OPERATING THE MATRIX SWITCHER
The HMX-244 is a matrix switcher capable of routing
audio/video signals from any of four sources to any of four
displays. The matrix may be operated by the front panel
controls, an IR remote control, or by RS-232 through a
computer or other third party controller.
The HMX-244 begins to operate as soon as power is
turned on, handshaking with sources and displays. Unused
ports do not operate
6.1 FRONT PANEL CONTROLS
Repeatedly press the SOURCE button in the appropriate
zone until the desired source (1, 2, 3, or 4) is selected.
• Lights (1-4) indicate the source that is currently selected
to the zone output.
• If a source is not powered on, the HMX-244 skips to the
next available source.
• The Power light indicates that the unit is receiving
power.
6.2 IR REMOTE CONTROLS
The HMX-244 includes a main remote control that can be
used at the head end matrix location. It controls sources for
all four zones. Each row of buttons represents a zone. To
disconnect all sources from a zone, press OFF.
Auto Mode may be used to avoid any TV showing a blank
screen. It automatically searches for a source input with
active video signal beginning with input 1. If no signal is
present, it searches input 2, 3, and 4. Override Auto Mode
in any zone by pressing one of the other source buttons.
Each 1380R Cat 5 zone receiver includes a zone IR
remote control. It controls only the zone output where the
1380R is located. The IR ports are only active when an
HDMI signal is present on both the source and respective
zone. If an external IR receiver is required, purchase a
5V demodulated IR receiver such as Model 804-052 from
Audio Authority.
6.3 RS-232 SERIAL CONTROL
Connect a computer or other serial controller to the RS-232
port on the rear panel using an RS-232 cable. The HMX-
244 serial commands are based on Windows™ OS super
terminal. Commands include on, off, and source selection
on any zone output.
Chose the right COM when setting “super terminal” and
then set the parameters as follows:
Baud Rate: 4800 bps
Data bit: 8 Bits
Parity: None
Stop Bit: 1 bit
Data stream: None
• Each command should be two or three characters,
followed by a carriage return. After each command, the
HMX-244 responds with “successful operation”.
• The next command must be sent within three seconds or
the error message: ”Overtime instruction” appears.
• If an incorrect command is received, the error: “wrong
instruction” appears.
• If the input or output is not connected or not in powered
on, “ineffective instruction” appears.
SERIAL COMMANDS
These commands are for the HMX-244 only. The serial
port on the Model 1380R receiver is not used.
The character for the zone output (A, B, C, or D) comes
rst, then the number for the source input:
• zone 3 to source 2 = C3(carriage return)
• zone 1 to source 4 = A4(carriage return), etc.
To turn the HMX-244 on or off enter the following:
• ON(carriage return)
• OFF(carriage return)
To query the status of the HMX-244 enter the following:
• QS(carriage return)
Important: all serial commands must be terminated with a
carriage return and line feed.

Audio Authority® Model HMX-244 User Manual 9
• Make certain that the matrix is receiving power by
looking at the power LED. It should be illuminated and
not ickering. Intermittent operation generally means a
problem with the DC power adapter or low AC voltage.
Check the AC outlet for proper voltage, then consider
replacing the DC power adapter.
• If some lower resolution TVs do not display a picture,
make sure the source is producing a resolution that all
TVs can accept. Try 1080i, 720p and 480p. If possible,
manually set the sources to the desired resolution. In
some cases, hot-plugging a high resolution display may
actually reset the source to a resolution that cannot be
accepted by some other TVs.
• If displays seem to “lose signal” momentarily, it could be
normal HDMI switching behavior. All displays connected
to a source must handshake again when that source
is selected to a new display. This pause is normal and
required when switching HDCP encrypted signals.
• If some inputs function correctly and others do not,
interchange cables between sources and see if the
problem moves with the cables. If it moves, a bad cable
or cable connector is the probable reason for the trouble.
If the problem remains with one particular input, connect
that source to a different input using the same cable and
see if the problem moves to the new input. If it does, the
problem is with the source. Connect the source directly
to the lowest resolution display and adjust its output
settings and resolution until satisfactory function is
achieved.
• If 1080p resolution, deep color, and/or lossless audio is
desired, very high bandwidth is required. HDMI cable
design and quality are extremely important in long
cable runs where capacitance can severely effect the
bandwidth available. If a zone is not receiving HDMI
signals, rst make certain that the input cable is as short
as possible and none of the output cables are more than
15 meters long. Try reducing the resolution, color depth
and/or audio settings.
• Remember that HDMI devices communicate with
one another so the source device and all destination
devices must be fully HDMI compliant. In addition,
HDCP encryption requires processing dependent on the
equipment you have connected to both the source and
destination devices.
