Thank you for your purchase of our Model 2090 SUPER Encoder Board.
If you have any
comments or need additional information on the use of the
SUPER Encoder Board, please write us at:
Since we introduced the 2090 a few
weeks ago, I received many emails asking for a simple; less complicated
installation. So, as of
today, below is a less complicated
explanation on the Installation and use of our SUPER Rotary Encoder
Board.
INSTALLATION
Installing the SUPER Encoder Board
requires very little time. All you need is an unused USB Port. Additional
Ports can be added to your computer by using a device called a USB Hub.
These Hubs can be purchased for as little as $20.00 in the
Internet.
 Just plug a USB Cable Series
"B" into the jack on the 2090, then into the USB Port on your computer.
The computer will sense the Adapter and load the required software for its
proper operation. The 2090 will be sensed as "DTA Rotary Encoder". That's
all there is to the installation.
To verify that you computer has
accepted the Interface, you can goto the "Game Controller" window. To do
this, just click on "START" (located in the lower left hand corner of the
computer's monitor); then click on "Control Panel"; then "Game
Controller". Your computer should display the
following:
Highlight "DTA
Rotary Encoder" then click "Properties"
TABLE 1
The Properties Window indicates that
there are are 32 available switch locations, this is a mis-conception.
There are only 20 Buttons that can be used with your designs. The First 12
Digital Switches are RESERVED for use with the Rotary
Switches.
Downloading the Utility
Driver for the 2090 Super Encoder Board
For the proper operation on the Encoder
Board, you need to Download the Encoder Utility
Program. This program allows you to adjust "Pulse
Timing" and "Pluse Width" on each of the 6 Available Rotary Switches on
the 2090 board. The program will also allow you to connect a number of
Rotary Encoder Boards to the USB Port of same computer while allowing you
to keep track on timing pusles on each and every Rotary Switch available
on your system.
To the left is a photo of the
Encoder Utility Program showing suggested settings for the first six
Rotary Switches.
Please note that the Utility
Program shows 16 available Rotary Switches, these aditional settings is
for future expansion and is not available on the 2090 Board. Also take note that if you install 6 Rotary Encoders to the
board, there NO Digital Switch inputs available. All available pins
have been reserved for the Rotary Encoders. But if you require a Push
Button installed with your panel design; use a maxinum of 5 Rotary
Encoders. This arrangement will allow you to include 2 Push
Buttons.
To Download this FREE program;
click HERE
The number pair to the right of each setting shows the
"Control Panel" RED dot that will be lite when the Rotary Switch is
turned. Example: With the Rotary Switch connected to the 2090 Board at
Position #1, turning the knob to the LEFT will light-up the #1 RED Button
(quick pulse) as seen on the "Control Panel" window. Turn the Rotary
Switch to the RIGHT, the #2 RED Button will light with a short pulse. If
connected to Position #4, the Turning the Rotary Dial to the LEFT then to
the RIGHT will light (again a pulse) the RED #7 and then the RED #8. You
get the idea.
On the top he Utility Program window, you will notice
"Serial Number". Here you can set the timing and pulse duration for a
number of 2090 Boards connected to your computer. This Serial Number will
change when additional boards are added. Just select the Board you wish to
program via its Serial Number, then set the timing pulse for the sugested
1:4 and Pulse width to 88 ms.
"SIMPLE" Wiring Your Model 2090 Super Encoder
Board
The 2090 was designed to provide
three vital functions to any Flight Simmers Avionics Panel; they are
Rotary Encoder Switches; Analog inputs from slide or rotary potentiometers
and Digital inputs for 20 Push Buttons.
To make the interfacing of your
Rotary Switches, Slide Controls and Push Buttons as painless as
possible, we have included fourteen 3 and two 6 pin Female Connectors.
Just solder the wires (as shown below) from your switches to the
connectors and place them on the 2090.
What could be easier?
Wiring the Rotary
Switches
To connect the Rotary Switches to the 2090, all you need
do it to solder 3 wires from the switch to one of the 3 pin female
connectors provided with your purchase.
The length of these wires can be
up to 15 inches long. Any longer, you run the risk of introducing noise
into the board.
Using the schematic to the left,
you can wire up to 6 Rotary Switches in this manner. The two additional
terminals on the Rotary Switch are the contacts connected to a
normally open spring return switch. These two contacts can be wired to the
Digital Switch Matrix (see below) so when the Rotary Switch is PUSHED, the
internal switch is closed for as long as you keep pressure on the shaft.
This switch closure can then be programmed using FSUIPC to preform a
needed function for your Avionics Panel.
Not all Rotary Switches come with
a n/o switch but the switches we are making available to you have this
unique feature.
Wiring the
LINEAR Potentiometers
So you want to design
a Throttle Quadrant? Well, you came to the right place. You can make your
own Throttle by starting with the purchase of a 100K Ohm Potentiometer,
Make sure ist is a LINEAR type. Audio taper will not work properly.
Luckly, Desktop Aviator has the Linear Potentiometers available
HERE.
To the left is a 100K Ohm Linear
Potentiometer with a short shaft (0.5in). Wiring of this pot is the same
as the Rotary Switch seen above. This time, you can wire up to 8
potentiometers for one 2090 Board.
Wiring the 1090
Slide Assemblies
If you purchased the 2090 with
the optional Cessna Style Push/Pull Slide Assembly;
read on. Just like wiring
the 100K Ohm Potentiometers as seen above, wiring the
Model 1090 Slide Assemblies
is just as easy.
To the left is the schematic on
soldering the 3 wires from the slide to the 3 terminal
connector.
Terminal #1 from the Slide is
soldered to the Right terminal on the connector;
Terminal #2 from the Slide
is soldered to the Center terminal of the connector;
Terminal #3 from the Slide
is soldered to the Left terminal of the
connector.
Note that the 1090 Slide has TWO
#2 terminals. This just means that these 2
terminals are connected
internally. Use the #2 terminal that is the closest to
the Slide's Mounting
Hub.
If you plan on designing a
Throttle Quadrant for the Cessna 172, you will need
2 of these Slide Assemblies.
One for the "Throttle" and the second for "Fuel Mix".
For the Skylane, you would
need three; One for "Throttle", the second for "Prop
Pitch" and the third for
"Fuel Mix".
If you wish to purchase
additional 1090 Slide Assemblies, you can goto:
If you wish, you can purchase
your own 100K Ohm Slide
Potentiometer.
Just make sure it is a "LINEAR
TYPE"; Audio Taper will not
operate correctly.
Switch Assignments for the
Model 2090
For the
"Simplified" installation, you can take up to 6 Rotary Encoders;
(wired as shown above). Connect them to the 2090 board using the 3 pin
male connectors. But if you install 6 Rotary Encoders, you have NO
Available inputs for Push Button Switches. So if you need a push button
switch in your design, add only 5 Rotary encoders. With 5 Encoders
connected, you will have 2 available Push
Buttons.
Likewise, if you
install 4 Encoders; you will have 4 available slots for Push
Buttons
Install 3 Encoders;
you will have 6 available slots for Push
Buttons.
Install 2 Encoders;
you will have 8 available slots for Push
Buttons.
Install 1 Encoder;
you will have 10 available slots for Push
Buttons.
Each Rotary Encoder requires 2 switch
inputs to the computer. One switch pulsing when the Encoder is turned to
the LEFT and a second switch when the Encoder is turned to the RIGHT. In
the "Simple" wiring arrangement; there are 12 available switches, thus if
each Encoder requires two switches and only 12 are available, you are
allowed to connect 6 Rotary Encoders to the 2090 board.
Using less Encoders, frees up more inputs
for use with Push or even Toggle Switches.
What Do I Do With All This
Wire?
I'm glad you asked. Below is a photo of
the 2090 Board that answers that perplexing question.
The "RED" oval shows where the 6
Rotary Switches can to be placed. Note the 3 Male Connectors in each row
(left to right). This is where you will place
the 3 terminal Female Connector. The one you just soldered the wires
to.
The "Yellow" oval shows where you connect the
available inputs to your Push Button (or Toggle) switches to the 2090
using the 6 Pin Female Connectors. This section is divided into
2 Male Terminal Posts. The left containes the row
component and the right side is the column. ROW 1, Row 2, Row 3, ROW 4,
ROW 5 and ROW 6 correspond to the vertical components
of the switch matrix (see above). COLUMN 1, COLUMN 2, COLUMN 3, COLUMN
4, COLUMN 5 and COLUMN 6 corresponds to the
horizontal components of the switch matrix. Using
the two 6 Terminal Female Connectors, solder the
wires from your switch to the connectors
and then place them into the corresponding "ROW" / "COLUMN" Male
connections.
The "GREEN" pval shows where you
will insert the 3 pin connectors soldered to your Potentiometers. As with
the Rotary Switchs, the Potentiometers are inserted
horizontally.
The "BLUE" circle shows 5 pair of male
connectors. At the present time, these terminals are not used. They are
for future expansion.
Below are two TABLES showing the
Designations for the Analog / Rotary Inputs and the Digital
Matrix.
Lets start with the Analog Input TABLE.
When the 2090 is connected to your computer and viewed on the "Control
Panel" , you will see the window shown above (See Table 1). From this
Table, you can see that the 8 Analog Inputs have names. X/Y, Z Axis, Y
Rotation ect.
The X/Y Axis is usually associated with
adding a Joystick. Joysticks can be purchased over the Internet for a few
dollars and this is where it is connected to the 2090 Board (X Axis -
Position #1 & Y Axis - Position #4). But you may ask; Where is
Position #1? From the photo seen above; the #1 Positions for the three
functions is indicated by the "Orange" horizontal Bar.
Say you want to use the "Y Rotation Axis"
for one of your Slide Assemblies (any position can be used). Just place
the 3 terminal connector (horizontally) into Position #7. Fuel Mix can be
connected to Position #8 (Z Rotation Axis) and so on.
Rotary Switches are the same as the
Analog Inputs. Again, refer to TABLE 1. This time focus your attention on
the 32 RED Buttons. These Buttons indicate the available 32 Digital
Switches of the MATRIX. The first 12 buttons are used for the Rotary
Switches and/or Push Button. Say you place the 3 terminal connector from
one of your Rotary Switches and place it Horizontally into Position #1
(Rotary Input Side "RED Circle"). When connected to your computer's USB
Port and the computer showing the the Control Panel (As seen in TABLE 1),
turn the Rotary Switch to the left and then the right. The RED Buttons #3
and #4 will begin to flash as you turn the switch. Now place a Rotary
Switch into Position #4. When turned, left then right, the RED Buttons #11
and #12 will flash. If you see erratic behaviour when turning the Switch
make sure you have the Rotary Switch UTILITY Programming running and
properly set for the 6 Rotary Switches (see above)

* To make use of the
Available Switch Assignments, just short the indicated ROW or Column pin
to GROUND. Example: Say you have one Encoder connected to the
2090 board at Position #1, you have 10 Available Switch Assignments. Just
short the pin from Column 3 to GROUND through a Push Button Switch. You
can also short Column 4,5,6 and Row 1,2,3,4,5,6. Say you have 5 encoders
connected to Positions 1,2,3,4,5 on the 2090 board. Now the available
switch assignments are only 2; Row 5 and Row 6. Now you have only 2
available switch assignments. And so On!
The Panasonic Rotary Encoders available from Desktop
Aviator have an internal Normally Open that can be used for this purpose.
Just solder one side of the two available terminals, to GROUND and the
other side to the appropriate Column/Row matrix.
NOTE: If you have only one Encoder in Position #1, you
need to set the Utility Program to "OFF" for 3-4, 5-6, 7-8, 9-10, 11-12.
Likewise; if you are using 2, 3, or 4 Encoders, the
setting for ALL UNUSED encoders MUST BE SET TO "OFF". If not, you
will be loosing the available "Switch Assignments" associated
with that setting.
Adding Toggle Switches
Seeing that all you need do to activate one of the
available Digital inputs it to Ground a Column/Row terminal, the "Pluse
Generator" circuit from our Model 2040 can be used. Just solder the
1N4148 Diode to one of the available Digital inputs and the Common Ground.
The circuit will generate a ground pulse for about 1/4 second, thus
turning "ON" the "Red Button" seen on the "Control Panel".
NOTE: A H11AA1 IC can also be used in place of the
H11AA2 without any problems.
Building a NAV/COM Radio with the
2090
Now that we know how to wire-up some
Rotary Encoders, lets build a NAV/COM Radio. To build the Radio,
you need the following:
1 - 2090 SUPER Rotary Encoder
Board w/USB Cable
4 - Rotary Encoder
Switches
2 - Push
Buttons
1 - 2090 UTILITY Program (See
Above)
Wire four Rotary Encoders as seen above.
Take two Spring Return Push Buttons and wire them onto one of the two 6
pin Female Connectors at Row 3 and 4 (Row 5 and 6 is not
used).
Connect the four Encoder Switches
into the 2090 "Rotary Sw Input" (RED Oval). Place at Position #1, #2, #3
and #4. Now place the 6 pin Connector
onto the 2090 board at the "Digital Sw Input" ROW location (Yellow Oval).
That's all there is to it. Now we must Assign
the appropriate functions to the Radio using
FSUIPC.
Plug in your 2090 into a unused USB Port.
The Board will be sensed by your computer and the proper driver
software will be loaded. Remember to download, run
and set the 2090 Utility Program as seen above. As this Utility
program will now sense that a 2090 board is
connected to the computer by its unique Serial Number. Set the Utility
Program to read the first 4 Rotary Encoders (1-2, 3-4, 5-6, 7-8) as "1:4" with a Pluse Width of "88msec".
Remove the 2090 from your computer, Exit the Utility Program. Reload
the Utility Program again and reconnect the
2090 to your computer. To test the board, turn each Rotary Encoder left
and right. The associated Red Button will pulse as the Encoder is turned.
If the pulse is erratic, you must change the "Pulse Timing" and "Pluse
Width" to a more accurate setting. This is
achieved by trail and error.
For the Panasonic Rotary Encoders being
sold by Desktop Aviator; the "Pluse Timing" should read "1:2"; while the
"Pluse Width" is
"72msec". Just remember, with each change to the Utility Program you
must exit the program and run it again to accept the new
settings.
The 2090 board is now ready to accept FS
Assignments.
Run your Flight Simulator. Click on
"Settings" then "Assignments". Highlight "DTA Rotary Encoder" and DELETE
ALL Joystick Default settings that Flight
Simulator has placed here. If you do not delete these un-necessary
settings, you may run the risk of assigning 2
functions to the same switch.
Once all Default settings are deleted
press the "ALT" key to enter FSUIPC (Licensed Version). If you need additional
information on downloading, running and programming FSUIPC, you can goto:
With FSUIPC running, you can now program
the Rotary Encoders to function as if it were a NAV/COM Radio. The TABLE below shows the FSUIPC
Functions that need to be programmed for the Radio to function
correctly.
Turn the first Rotary Encoder "Clockwise"
and associate this switch to: COM RADIO WHOLE
INC. Turn the same Rotary Encoder "Counter-Clockwise" and associate this switch to: COM RADIO WHOLE DEC. Now take the second Rotary
Encoder and turn it "Clockwise". Associate
this switch to: COM RADIO FRAC INC. Now turn the second Rotary Encoder "Counter-Clockwise".
Associate this switch to: COM RADIO FRAC DEC.
Now, press one of your Spring Return Push
Buttons. Associate this switch to: COM STBY RADIO
SWAP. The second Push
Button is pressed and associated
with: NAV1 RADIO
SWAP.
For the remaining two Rotary Encoders,
program them just as I instructed above. This time, associate their
functions to the four NAV1 commands.

Turn both Rotary Encoders, first to the
left and then to the right. Take notics now the NAV and COM Radio
Frequencies change with the turning on the
Rotary Encoder Knobs. To SWAP the frequencies from Standby to Active, just
press the Push Button.
If you encounted some difficuilities with
the functions, go back into FSUIPC and double check your
settings.
If you really want the "LOOK" of a Radio
Shack; you need an Second NAV/COM Radio (NAV/COM 2). Just wire-up another
four Rotary Encoders and another 2 Push
Button Switches. This time, assign the Switches to the functions listed
below.

NOTE: The 2090 Utility
Program MUST BE RUN AGAIN to sense the second 2090 Board used for the
NAV/COM 2 Radio. Notice that there are 2 Serial Numbers seen this time.
Highlight the Serial Number for the New Board and set the Rotary Encoder
Inputs as seen
above. The UTILITY
Program needs to RUN everytime you add another 2090 Board to your computer
system
Now that you have 2 NAV/COM Radios,
you might want to consider enclosing them into a very handsome cabinet. We
have the perfect Cabinet for you. You can
purchase one at:
Additional 2090 Boards and Parts can also
be purchased here.
ADVANCED Encoder Wiring
Need Aditional Encoders and Digital
Switches? Below is a schematic that shows how to make use of the
"Digital Switch" input (Yellow Oval - see
above). Using this arrangement, you can add up to 16 Rotary Encoders. This
is a very complicated circuit and it should
be asembled only if you have an understanding of electronics and circuit
diagrams.
This layout will give you the option of
installing 16 Rotary Encoders BUT, seeing that each encoder requires 2
digital switches, and there are only 32
switches available; (16 x 2 = 32), there are NO Available Digital inputs
for Push Button switches. If you need some
switch inputs; lets modify the circuit a bit. Say you want only six Rotary
Encoders. Using six Encoders, this leaves 20 available inputs for the addition of Push Button
Switches.
To make this modification, just wire the
first six encoders as seen below (1, 2, 3, 4, 5 and
6). Now take a look at SCHEMATIC 2 (seen below).
SCHEMATIC 1
Just wire each of the 20
switches into the COLUMN/ROW Matrix. When complete, you can check your
wiring using the "Control Panel" window; just click on "DTA Rotary
Encoder".
When working to your
satisfaction, you can then run your Flight Simulator and program each
switch with the desired function. FSUIPS can also be used.
SCHEMATIC 2

Wiring the Switch Matrix
I've just finished writing a short .PDF
Article on wiring the Switch MATRIX on the 2090 Board. You can
