Hardware Installation
The HLX system is designed to be mounted in a standard
19-inch equipment rack. Secure the card cage to the rails
with all four screws (supplied). If your system includes
an expansion card cage (Model 2014) install it rst, then
carefully seat the main HLX card cage onto the multi-pin
connector and fasten it to the rack. Check that each pre-
installed card is properly seated and secured in the card
cage.
Wiring Sources and Initial Testing
Component Video Source Card – Model 2114
Connect high quality component video cables (YPbPr),
analog audio (L/R) and either digital coaxial audio or digital
optical audio (one form of digital audio ONLY) to each
source input. If both analog and digital audio signals are
desired in a zone, both digital AND anlalog audio inputs
must be connected from the source to the HLX source
card.
Source Card IR Outputs
IR outputs on source cards relay IR data from the zones to
the source device. Connect IR emitters or blasters from the
IR output jacks on each source card to each source device.
Place the blaster directly over the IR receiver on the front
panel, or, if available, connect a patch cord to the IR input
on the rear panel.
Wiring Dual Cat 5 Zones
• Zone Card – Model 2248 Carefully mark two Cat 5e/6
cables as cable A and B and pull them to the receiver
location. It is imperative that the A and B cables are
correctly connected to the zone receiver and the zone
card; swapping cables can result in permanent damage
to the receiver.
• Zone Receiver – Model 9879 Carefully connect the
cables marked A and B to the appropriate Cat 5 jacks
on the zone receiver. Set the cable length compensation
rotary switch based on the length of the cables (0 for
0-99 feet, 1 for 100-199 feet, etc). Connect high quality
component video, analog audio, and digital coaxial
audio cables to the zone receiver. Finally, connect an IR
receiver to the front or back of the zone receiver.
• IR Input and Output jacks – The two 3.5mm jacks for
each zone card output are used for special control
signals. The IN jack sends signals to the HLX and to
sources via the source card IR jacks. The OUT jack
sends OR recieves signals via the Cat 5 zone pathway.
• Zone IR 12V Power – Do not turn on (down position) the
12V switch unless compatible equipment requires 12V
power. See the example diagram on page 12 for details.

Control Options
Centralized serial Ethernet control systems provide
the most robust and complete HLX control, however,
comprehensive IR controllers and zone IR control are good
alternatives for most day to day activities.
Ethernet or RS-232 Serial Control
System controllers and PCs can send all setup and
control commands via the RS-232 serial port and receive
feedback.
• Important: observe the correct pinout for controlling the
HLX via RS-232 cable
• Serial control is capable of performing all commands
• See page 19 for details on using serial commands
IR Control Options
The HLX can be controlled through IR commands issued
at each zone, or via the IR inputs at the head end (see
example systems below). Either use an IR remote with a
receiver connected to the IR jack on the zone receiver, or
program an RF controller or other control system with HLX
IR commands and connect its outputs to the IR input jacks
on the 2248 zone card. (12 volt switches should be OFF, in
the up position.)

Comprehensive IR Control System
The HLX can be used right out of the box; no setup is
necessary. Comprehensive IR controllers can use the
complete HLX IR code set, along with the codes of the
sources. HLX volume controls are not included in this code
1. Patch the IR signal directly to the IR input port on the
rear panel using a standard 3.5mm cable or, place a
stick-on emitter or blaster from the infrared system on
the HLX front panel optical IR receiver.
2. If the HLX IR codes are available from your remote
control company, download and/or activate those les.
3. A HEX le can be downloaded from the Audio Authority
website: www.audioauthority.com/page/software.
Logitech Harmony remote controls can access
the HLX IR codes in the Harmony database here:
Amplier>Audio/Video Switch>Audio Authority>HLX.
Zone IR Control
1. Set up a programmable remote (URC, RTI, Logitech,
etc.) with HLX remote control codes.
2. Connect an IR receiver to the HLX system either by
running the IR receiver cable directly to the input of a
2248 Zone Card, or connect the IR receiver to the zone
receiver IR jack.
3. For operation tips, see the zone IR explanation in the
operation section below.
HLX Front Panel Controls
Front panel control is peformed via touch sensitive keys
and a selector knob.
• The default screen is the zone/source switching screen.
Scroll zones using the knob, press the knob to choose a
zone, then scroll and select a source.
• To perform multiple switching operations, use GROUP,
FAVORITE and ALL keys (some setup required).
• Touch MENU to access settings and scroll to a desired
item and press the knob to enter.
• Press the BACK key to exit.
Zone IR Operation
HLX “Buttons” for Remote Control Systems
When programming a remote control system, the following
functions are available for operational controls:
• Source Buttons: 12 discrete buttons cause the source
connected to the zone to be switched, given the current
conguration (sources that do not exist or that are
restricted in some way cannot be selected).
• Audio/Video Buttons: breakaway switching is possible
by rst pressing the audio or video button and then a
discrete source button; only the audio or video signal is
switched.
• Lock Access: remove other zones viewing the source
selected and temporarily restrict other zones from
selecting the source.
• Lock Control: temporarily restrict other zones from
passing IR to the selected source device.
• Unlock: cancel all temporary restrictions placed by the
activating zone.
• Digits: the 0-9 digits on the remote can be used to enter
group or favorite numbers.
• Favorites: activates a predetermined combination of
zone/source selections; requires a number to be entered
on the 0-9 digits (1-10) before pressing the favorite
button for activation.
• Groups: sets a predetermined list of zones to the
specied source video, audio or both. This command
requires one to press the desired group number, group
button, audio or video modiers, and nally the source
button.
IR Operation Example
Current Conguration:
• 8 source inputs (1-8)
• 8 zone outputs (1-8) on a Model 2248 output card
• No restrictions in place
• IR receiver connected to the HLX zone 1 IR input
• Favorite 7 is dened as: “zones 1-8 switch to source 2”
• Group 1 contains zones 1-4
Example Sequence of Commands
1. [SOURCE1] – zone 1 is connected to source 1
2. [VIDEO][SOURCE2] – switch zone 1 to view source 2
but remain listening to source 1
3. [LOCK ACCESS] – temporarily restrict zones 2-8 from
viewing source 2, the currently viewed source in zone
1. Breakaway is canceled for zone 1 and zone 1 is
forced to view and listen to source 2, the source that it
was viewing when the restriction was activated.
Operation

12 Audio Authority HLX Series User Manual
4. [SOURCE1] – switch zone 1 back to watching/listening
to source 1. The temporary restriction is canceled by
switching away from the restricted source.
5. [LOCK CONTROL] – temporarily restrict zones 2-8
from passing IR control to source 1. For example,
source 1 may be connected to a DVD player. Zones
2-8 would be unable to use DVD player IR remote
commands to enter commands such as stop, pause,
skip, etc.
6. [UNLOCK] – removes the temporary restriction of
controlling source 1.
7. [VOLUME UP] – has no effect on output cards that do
not have physical analog outputs; adjusts the volume
on an output card that has physical analog audio
outputs
8. [ 7 ][FAVORITE] – all zones 1-8 switch to source 2
9. [ 1 ][GROUP][VIDEO][SOURCE4] – zones 1-4 are
switched to watching source 4 video, but remain
listening to the audio connected to the previous
selection (source 2)
* “View,” In the context of restrictions, means to select,
watch and/or listen to a given source. The term “control”
means to send IR commands through the HLX IR pathway
to control a source (e.g. change channels, stop, play, etc.).
Using Restrictions
The HLX system can be set up to deny certain
zones access to certain sources. These “restrictions”
can be either permanent (until reprogrammed) or
temporary (active until they are cancelled or expire).
Temporary Source Restrictions
This feature allows a viewer in one zone to view*
content privately; no other zone is able to view the
source while the temporary restriction is in place.
When activated, this restriction removes other zones
currently viewing the source. Temporary restrictions
automatically expire after ve hours; alternatively
they are canceled by switching away from the
restricted source or explicitly issuing an unlock
command.
When a zone is removed from a newly restricted
source, it is automatically switched to the next
available source.
Example of Temporary Restriction
• Zone 1 and zone 2 are viewing source 7.
• Zone 2 applies a temporary viewing restriction to
source 7.
• Zone 1 is switched to source 8 (presuming there is
no restriction in place that will prevent that action).
If there is a restriction in place that prevents
switching to a zone, the next zone is attempted.
If a zone only has access to a single source,
and that source becomes restricted, the zone
deactivates (black screen).
Placing and cancelling temporary restrictions have
other limitations based on the control interface and
will be described in their respective sections.
Temporary Control Restrictions (IR)
A Control Restriction prevents other zones from
controlling* the selected source through the HLX
integrated IR control pathway. Other zones may still
view the source. Temporary restrictions expire after
ve hours, or by switching away from the restricted
source or issuing an unlock command.
Permanent Source Restrictions
When a zone is permanently restricted from viewing
a source, it may not select or view that source under
any circumstances. Temporary source restrictions
supplement permanent restrictions, and may add
further restrictions to the available sources that a
zone may access. Permanent source restrictions
can be applied or removed only through serial
or Ethernet commands, or by using the HLX
conguration utility on a PC.

Serial Control
Serial commands can be used at any time via RS-232 or
Ethernet to change the HLX settings. See page 19 for a
complete list of commands.

• All serial commands require opening and closing
brackets “[ ]” but do not require any periods, spaces, or
commas.
• Commands can be in any order: [RPZ1] = [R, Z1, P]
• Enter a line feed and carriage return after each
command.
• ASCII codes not specied are ignored (i.e. control codes,
unused alphanumeric characters, etc.).
Setup for Ethernet Control
Consult your network administrator if you are unfamiliar
with setting up a network connection.
HLX commands (see page 19 for a complete list) can
be issued using an Ethernet connection and a telnet
program. There are two LED indicators located next to the
Ethernet port N on the rear panel that will help in identifying
connection issues:
• Link - The Link LED is steadily lit if a connection is
detected and ashes when activity is present.
• Speed - The Speed LED is off for 10 base T, and on for
100 base T.
Using the Ethernet Port
Use a telnet client or terminal
program on a Mac or PC to send
and receive commands through
the Ethernet port on the HLX. Connect a PC directly to
the Ethernet port using a crossover cable, or alternatively
use a standard Ethernet hub or switch and standard patch
cables. Once connected to a PC or network, by default the
HLX attempts to obtain an IP address automatically using
DHCP. To use static settings, see below.
Using DHCP
DHCP is enabled on the HLX by default. If DHCP is
enabled on your network, simply connect the HLX to
the network with an existing DHCP server to obtain all
necessary settings.
Static Addressing (Connected to a PC)
• The HLX must be given an IP address which will not
conict with the PC. Go to the network settings (which
are found in control panel -> network -> local connection
properties of a PC running Windows XP).
• Change the TCP/IP protocol properties, and set the
IP address, gateway, and subnet mask, if they are
not already set. This can be arbitrarily done on a
direct connection, but a good choice for the settings
would be IP address of 192.168.0.1, subnet mask of
255.255.255.0, and an empty default gateway. Once
these values have been set, use serial commands to set
the network settings of the HLX in a similar manner, but
use a different IP address than that of the computer (for
example, 192.168.0.2).
Static Addressing (Through a Network)
• The HLX must be set to the same settings as the PC
except for the IP address, which must be one available
on the network. To determine this in Windows, use the
DOS prompt (Start->Run->cmd) commands ipcong
and ping. Ipcong will list the PC’s settings, and ping will
allow you to test addresses to make sure that nothing
else on the network has that address.
• Once connectivity is established, a telnet program such
as Hyper Terminal, Teraterm, PuTTY etc, must be used
to connect to the device. Enter the IP address of the
HLX and leave the default port (23) to connect. Once
connected, standard serial commands (listed in Appendix
A) can be issued in an identical manner to serial control.

IR Interference
There are many sources of possible IR interference
including LCD/Plasma screens, uorescent lights, or space
heaters. IR receivers are unable to operate properly in the
presence of signicant interference.
1. Eliminate source of interference and use Plasma-proof
and/or LCD-proof IR receivers
2. Experiment with relocating the IR receiver
3. Check for IR interference using the IR diagnostics
IR Compatibility
The HLX only works with 12 volt, three-wire receivers
(example, Xantech 291 Series).
IR Connectivity Problems
1. Use a professional cable tester and re-terminate bad
cable ends using EIA-568B color code.
2. IR receivers require power and may receive it from a
connecting block or from a Zone card itself depending on
the conguration. Contact support.
Note: native HLX IR commands sent from zone IR ports
are not passed to any of the HLX IR output jacks.

Card Placement Rules
Systems are pre-assembled at the factory, but for eld
updates, observe the following rules. Slide each card into
the HLX card cage and secure using the provided screws.
1. The rst card slot must have a source card installed.
2. Slot 2 may have a source card installed or may be left
empty. Do not install a zone card in slot 2.
3. Slot 3 accepts either a source or zone card.
5. Slots 4, 5, and 6 accept zone cards only*.
6. Sources and zones are numbered sequentially, left to
right, starting with the top card in the card cage.
7. Adding cards to an existing system requires inserting the
card at the bottom of the respective stack; a source card
should be added after the last source card in the system,
shifting zone cards down if necessary. Zone cards should
be added in the next available slot, below the existing
zone cards.
Source Cards
Source cards must be placed into the top two or three slots.
Do not leave vacant slots between source cards.
• Slot 1 – Source Card 1, Source 1-4
• Slot 2 – Source Card 2, Source 5-8
• Slot 3 – Source Card 3, Source 9-12
Zone Cards
Zone cards must be installed in valid zone card slots, but
are not required to be installed contiguously. The zones will
be numbered in order, based on the card location in the
card cage, however.
• Slot 3 – Zone Card 1, zones 1-8
• Slot 4 – Zone Card
• Slot 5+ – Zone Card

Using the PC Conguration Utility
The HLX Conguration Utility allows easy setup and conguration of HLX components. It is
not a real-time control utility. It may be used to set up groups and favorites, dene restrictions,
and name sources and zones. The HLX Conguration Utility may be operated directly by
serial connection, through Ethernet or in “le mode”. See page 14 for serial and Ethernet
connection details. In le mode, the utility saves a script le (CONFIG.HLX) to a USB drive
that can be loaded via the HLX USB port. A copy of the le can be stored as a backup in a
safe location. Download the PC Conguration Utility from
www.audioauthority.com/page/software.
Favorites may be dened with sychronized audio and video, or breakaway switching. The favorites screen also
shows permanent restrictions for reference.
