Introduction
The Model 902 and 903 Control Panels connect to the Access™ Demonstration Network switching system to
show the products currently selected to play and to provide an easy method of controlling the display to
select products, store and recall systems, and activate special features. The panel controls are divided into
three functional sections - a selection keypad, a Product Group selection area and (902 only) an Equal Volume
Comparison (EVC) section. See the illustration below.

In addition to the 902 or 903 Control Panel, the Access™ System can also be operated by:
• Product Select Buttons - push-button located next to each product
• Model 905 Remote Control - a small, inexpensive, full-function remote (included with the 902 and
optional for the 903)
• Compatible PC/Modem - system input/output via the control panel’s RS-232 serial port.
One unique characteristic of the Access System is that all of these different modes of product selection may be
used in the same system. This means that your system could contain a Control Panel, an IR Remote, and
Product Select Buttons, as well as an external computer or modem hooked to the Control Panel’s RS-232 port.
So, it is important for you to be familiar with your system and know the different modes of access (input) to
your system.

Configuring the Control Panel
On the back of the Control Panel is a bank of Configuration DIP Switches that enable or disable certain
functions. These switch settings should have been adjusted to match your merchandising requirements
during the installation, however, they may be changed at any time. The following chart details the function
of each switch.

Factory
Switch Function Setting Comment
A Key Click O Provides audible feedback of key presses (beep)
B Demo Mode O Turn ON only when control panel is not connected to a
system as a “Training Mode”
C Systems Product Group ON ON makes the last unused Product Group capable of
storing and recalling 99 system configurations
D Not Currently Used O
E Previous Selection Key O O = “C” key is the third “flash memory” key
ON = “C” key is toggle between current selection and previous
selection
903 Mode ON This switch must be O for the Model 902 and ON for the 903
G Internal IR Receiver ON Turn ON if using Model 905 remote control
H Auxiliary IR Port O Turn ON if using 990 auxiliary infrared remote receiver.
Switch-C is of particular interest for most retailers. Turning Switch-C to ON allows the last Product Group
position on the Control Panel to be used for storing and recalling up to 99 different component systems. If the
system includes 904 Product Group Expanders, the Systems Product Group will be the last position, on the
last 904. When this feature is enabled, the Systems Product Group will display dashes (– –) or a System
number in its window.
or those whose merchandising emphasizes direct A/B type product comparisons, Switch-E offers an inter-
esting option. Turning Switch-E to ON will change the function of the C-Key from a temporary system
storage key, to an A/B key that reverts to the previous selection whenever it is pressed. This allows for a
simple, one-button A/B capability without having to “store” anything. This feature is especially useful when
your demo includes putting the remote control in the customer’s hand and letting him/her switch at will,
using just one button.
If your installation includes the Model 990 Ceiling-Mounted Infrared Receiver, then Switch-H must be
enabled for that device to operate. If there is no remote control in your system, you should turn Switch-G
O , to eliminate any possibility of stray infrared signals or other “noise” from affecting the display.
The configuration DIP switches are read by the Control Panel each time it is reset or powered up. Therefore,
for any changes to the configuration DIP switches to become effective, the Control Panel must be reset (see
Secure eatures section, Secure 88) or powered down and restarted for the changes to be recognized.

Connecting the 902 or 903 to the Access™System
Control panels connect to the Access System via the Model 980 System Module (See Hookup Diagram below).
They also have terminals for the connection of an auxiliary ceiling-mounted Omnidirectional Infrared Re-
ceiver, which extends the range of the remote control’s operation.
Definitions of Special Terms
To best understand and use this powerful merchandising tool, it will be helpful to clarify a few terms used
throughout this manual.
COMPONENT The merchandise or products connected to the switching system.
SWITCH MODULE Small, intelligent, circuit board assembly that provides the actual switching for 4
to 8 components in the system. All components are connected to switch modules,
which in turn selectively interconnect products for demonstration. Your system
may contain several types of switch modules – Low-Level modules for sources or
amplifier inputs, High-Level modules for amplifier outputs, Speaker modules,
Video modules, and so forth. The quantities and types of modules contained in
your system depend on the number and types of components in your display.
SYSTEM BUS A set of wires which interconnect all switch modules allowing control signals
(instructions) to flow between them. The system bus is color-coded, using red/
yellow/black/blue wires and operates as an RS-485 serial interface.
ADDRESS Like your street address, a unique logical numeric code assigned to each module
to differentiate it from all others and enable reliable delivery of instructions via
the System Bus. Each module in the display can “talk” to and receive instructions
from the Control Panel, Product Select Buttons, the 905 IR Remote, a local PC, or a
PC via modem.
Product Group A group of functionally similar components within the display, such as
or GROUP CD players, amplifiers, front speakers, subwoofers, VCRs, etc. The 902 Control
Panel has provisions for 8 Product Groups and has capacity for 99 components in
each Product Group. The number of Product Groups can be expanded by adding
a 904 Product Group Expander. Each 904 Expander adds 8 more Product Groups
to the system, each capable of 99 components. You can add three 904s making the
Access System’s total capacity 16 electronic Product Groups and 16 speaker
Product Groups, each capable of handling 99 products, for a total of 3,168 prod-
ucts in a system.

SELECTED The Product Group currently selected to be the object of keypad input.
PRODUCT GROUP A Product Group is selected by pressing its Select Key and confirmed by the
illumination of its red LED Indicator. When “selected,” input from the numeric
keypad will be displayed in the selected Product Group’s 2-digit window and
directed to its switch modules.
ACTIVE Any Component or Product Group that is currently selected to play, i.e. part of the
signal path. The 2-digit number for all active components is shown in its respec-
tive Product Group window.
PRESS A momentary press and release of a key . The PRESS is used for primary key
functions like entering numbers or selecting a Product Group.
DOUBLE-CLICK To press and release a key twice in rapid succession. Used for alternate key
functions, such as turning off an active Product Group.
LPRESS To press and hold a key until the Control Panel beeps (about 1/2 second) then
release. LPRESS is generally used to store values. Examples are defining systems
and storing current selections using A/B/C keys, etc.
HOLD To HOLD a key down while PRESSing other keys, like the “Shift” key on a
computer keyboard.
TIMEOUT The automatic termination of an incomplete keypad or remote control command
after a set amount of time; the control panel is restored to its previous state.
Starting the System the First Time
Once installed, the Access™ System should be tested prior to connecting components to the switching mod-
ules. A self-test routine is automatically initiated when you first power-up the system. When the system is
powered up, you should observe the following sequence of events in the system.
A. 902/903 Test Sequence. If you encounter any problems, keep a note pad handy to record results as they
are reported in the Control Panel windows.
1. All display segments and indicators on the control panel are lit briefly (lamp test).
2. The EVC window at the left of the panel displays software version (e.g., 3.4).
3. A System Bus Test is performed. If the word “bUS” flashes in the EVC window, it indicates a
problem with a system bus cable or switching module. To find the faulty cable or module, use this
process of elimination:
• Carefully unplug the yellow-red-blue-black system bus cable from a switch module to
isolate it from the 980 module, then press any key on the control panel.
• If “bUS” still appears on the EVC window, plug the cable back in and try a different
module.
• If “bUS” disappears from the EVC window, you have isolated the module or section of
bus cable that is faulty. Call Audio Authority® Technical Service at 800-322-8346 for
assistance with parts replacement.
4. After the bus test, the diagnostic program scans the active range of module addresses in every
Product Group. You will observe these module addresses counting up in the EVC window as the
product group number is displayed in each group’s Product Group window.
• If the numeric displays begin flashing at any time during the module scan, two or more
modules have the same address. Duplicate addresses are disallowed because the control
panel is unable to tell two identically addressed modules apart. Note the last group
7
number displayed in the Product Group windows and the module number displayed in
the EVC window and try to find two modules that both have this address. or example, if
the control panel is flashing, the EVC window displays 002, and the third Product Group
window shows S4, you would look for two speaker modules (932) with the same address
of “Group 4, Module 02, Right.” Remember that pairs of speaker modules must have the
same Group and Module ID address, but must be identified LE T and RIGHT to avoid a
duplication.
Note: In Control Panels, “E” refers to Electronics switching modules and “S” refers to Speaker
switching modules.
• As each new group number appears in a Product Group window, the EVC window counts
up the number of modules in that group that can be recognized. Write down the highest
number reported in the EVC window and the Group number with it. or each group,
compare the reported module tally with a physical count of the modules. or example,
your system has four “E Group 0” modules, six “E Group 4” modules, and three pairs of
“S Group 4” modules. The top PG window displays “E0” as EVC scans up to 4 (good).
The second PG window displays “E4” as EVC scans up to 5 (bad). The third PG window
displays “S4” as EVC scans up to 3 (good). In this case you would look for a mis-ad-
dressed, unplugged, or faulty E4 module (Electronics Group 4).
• If the module count in a group does not match the number of modules you actually have,
look for disconnected or mis-addressed modules.
B) After the diagnostic routine, the Control Panel software version number will be displayed, and the Control
Panel will BEEP to indicate that it is ready for use.
At this point the Control Panel should display “– –” or numbers in the window of each valid Product Group.
If this exact sequence of events does not occur, there is a problem with the installation. Do not proceed with
connecting product to the system until the all installation problems have been resolved. If you need assis-
tance, call our Technical Service Department toll-free at 800/322-8346.
When the system is turned on each time hereafter, the selection last made, or a default system that has been
programmed will appear in the Product Group windows.
How Product Groups Appear on the Control Panel
Module addresses set during installation determine the order in which Product Groups appear on the Control
Panel. If the rules for addressing described in the Installation Manual are followed, the first (top) Product
Group should be Sources, with the next logical component Product Group in the signal path being the second
Product Group (e.g. amplifiers, or maybe preamp EQs or processors). Here are two examples of how Product
Groups might be configured on your Control Panel:
Product Group Window Home Audio Display Car Audio Display
1 A/V Sources Head Units
2 Surround Receivers Preamp EQs
3 ront Speakers ront Amps
4 Center Channel Speakers Rear Amps
5 Rear Speakers ront Speakers
6 Subwoofers Rear Speakers
7 – – Sub Amps
8 Systems (up to 99) Subwoofers
Notice that the Product Groups are in a logical order that represents the normal signal flow of the compo-
nents if they were “hard-wired.” Notice also that speaker Product Groups follow their related amplifier’s
Product Group. Your particular demonstration needs may not require that all Product Groups be used,
8
leaving some vacant (i.e. no attached switching modules). If this is the case, then your 902/903 Control Panel
can be used very creatively by programming a single promotional system into each unused Product Group,
for instant one-button activation. Such a configuration might use Product Groups 4 - 7 like this:
Product Group Window Audio Video System
1 Sources
2 Receivers
3 Speakers
4 Manager’s Special
5 $649 Installed!
6 The Latest Technology
7 Advertised Special $499
8 Systems
The last Product Group can store up to 99 preprogrammed systems of your choice if there are no components
assigned to that Product Group. To enable this feature, DIP Switch “C” on the Control Panel’s Configuration
DIP Switch array must be ON. See the diagram on page 3.
Blank and printed labels for all types of component Product Groups are included with your 902 or 903
Control Panel. However, you may wish to make your own labels using different words, symbols or lan-
guages, maybe even on different colored paper. If so, custom label inserts can be printed on 20 - 24# paper
using the following specifications:
Label size: .45” H x 2” W Max. Text Width: 1-3/8”
Text Center: 11/16” from left edge Max. Text Height: 3/8”
Selecting Products
To select a product from the Control Panel by the product number:
1. PRESS the desired Product Group Select Key if that group is not already Selected.
2. Enter a 1 or 2 digit product number using the numeric keypad (the Product Group display clears
and then flashes the new entry).
3. PRESS the Product Group Select Key to enter your new selection.
You may also simply wait 2 seconds and the new selection will be entered automatically without PRESSing
the SELECTED Product Group key. Any component in any Product Group can be SELECTED in this manner
(Auto-Enter).
To play multiple pairs of speakers in the same Product Group:
1. Make sure the desired speaker Product Group is SELECTED (LED ON).
2. Enter 1 or 2 digit number of speaker pair you wish to add and LPRESS Product Group key.
The SELECTED speaker’s Product Group window will alternately display the two speaker pair numbers.
You may add more speaker pairs in the same manner (depending on system limitations set during installa-
tion), but remember that you could be presenting a severe load (low impedance) to the amp’s output, so be
careful. Check the receiver or amplifier manufacturer’s recommendations for maximum number of speakers.
To deselect one of the speaker pairs playing in the same Product Group:
1. Enter the 1 or 2 digit number of the pair you wish to deselect, and
2. PRESS the corresponding Product Group key or simply wait for Auto-Enter.
Note: The maximum number of speakers that can play at the same time is determined by DIP Switch
settings on the 980 System Module Board. If you cannot select multiple speakers to play simultaneously,
please refer to the Installation Manual’s instructions on setting the 980 System Module or call the factory at
800-322-8346.
9
To select a product from the Control Panel using the UP/DOWN arrow keys:
1. PRESS the desired Product Group button if not already SELECTED.
2. Use the UP key (▲) to select next higher numbered product in Product Group and press repeat-
edly to continue advancing.
3. Use the DOWN key (▼) to select next lower number product in currently SELECTED Product
Group.
DOUBLE-CLICK of the UP/DOWN keys will increment/decrement product selection by a factor of 10. If
UP/DOWN arrow keys are used to scroll through a speaker Product Group where multiple pairs of speakers
are ACTIVE, then the most recent speaker selection is incremented or decremented. The other ACTIVE
speakers in the Product Group are not affected.
To turn off all products in a Product Group:
This may be done by either of two ways:
1) Deselect the Product Group by DOUBLE-CLICKing its Select Key, or
2) Deselect the ACTIVE product within that GROUP by entering its number again.
In both cases the result is the same. The Product Group window will display dashes (– –), indicating that the
Group is available, but not ACTIVE.
Storing and Demonstrating Component Systems
There are three different ways to store complete systems with 902 or 903 Control Panels. During product
demonstrations, it is normal to “build” a system for your customer as you qualify his/her needs during the
selling process. Once the components of the desired system are active, the system may be stored in one of the
following ways:
1) LPRESS the A, B, or C keys. These keys are essentially used like scratchpad or “flash” memory.
Once a system has been stored in this way, PRESS A, B, or C to instantly compare the stored
systems. uture systems can be stored in A, B, or C by repeating the same process thereby over-
writing the previously stored systems.
2) LPRESS any unused Product Group Select Key to store the system that is currently playing. Once
stored, the system can be SELECTED by simply PRESSing the Product Group key. When selected,
“SY” will be displayed in the system’s Product Group window and all the components comprising
the system will have their numbers displayed in their respective Product Group windows. uture
systems can be stored in the same manner by simply overwriting with a newly selected system.
3) Store as 1 of up to 99 systems in the Systems Product Group. To do this:
• Select the Systems Product Group by PRESSing its Select Key.
(DIP Switch-C must be ON).
• Enter a 1 or 2 digit number (e.g. #22) for the system.
• LPRESS the Systems Product Group’s Select Key to store.
Continue this procedure to store up to 99 systems. Systems that have been temporarily stored using the A, B,
or C keys may be copied to the System Product Group to prevent being erased.
To select a system previously stored in the System Product Group:
1) SELECT the Systems Product Group,
2) Enter the 1 or 2 digit system number you wish to play, and
3) PRESS the Systems Product Group key or wait 2 seconds for auto-enter.
You may also use the UP/DOWN arrow keys to scroll through systems.
