INSTALLATION
Installing the USB INTERFACE 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 2160, then into the USB Port on your computer.
The computer will sense the Adapter and load the required software for its
proper operation. The 2160 will be sensed as "One-Shot Pulse Generator
Model 2160". 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
"One-Shot Pulse Gen Model 2160" then click
"Properties"

of the "Calibration" Window where you can test the wiring of the 10 SPDT
Togle Switches
Wiring Your Model
2160
Below is a photo showing the 2160
Board with its J1 and J2 Headers. It is here (J1/J2) where we will
connect the Toggle Switches.
 From the photo above, you can see the
J1 and J2 connectors of the 2160. The connector on the left is designated
J1, while the connector on the right is J2. J1 & J2 are both 2x17 male
"Headers" giving you 34 pins for each connector. Note the "RED" DOT on
each of the Headers, The "RED" Dot indicates that this pin
is Position #1. The pin to the right of pin 1 is Position #2. To
activate a USB output, just short the 2 horizontal pins together. Example:
Take a screwdriver and short the #1 and #2 pins of the J1 connector and
take notice which "RED" Button lights inside the Calibration window. When
first shorted; the #1 "RED" Button will light for about 1/4 second. Now
remove the short; the "RED" Button will go out (note: No second pulse is
generated).
Now short J1's pin 3 and 4 together,
the #2 "RED" Button will flash for 1/4 second. And so on.
Now we know that shorting 2
adjacent pins will product "ONE" 1/4 second pulse. So lets combine TWO
pulses on ONE Toggle switch. This arrangement will give us the needed
pulses for our FALCON and IL-2 Flight Simulators assignments.
 Lets take a Toggle Switch with 3
terminals on the back. This is called a Single-Pole-Double-Throw (or SPDT
for short). Notice on the J1 connector, all the odd numbered pins ( 1, 3,
5, 7 ect) are all connected on the 2160 board to one common point, called
"Ground" (or GND); while on the J2 connector, all even numbered pins are
connected to GND (2, 4, 6, 8 ect). So with J1 in mind, lets connect the
center terminal of the toggle switch and solder it to any one of these ODD
Numbered pins (EVEN Numbered pins for the J2 Connector). Now lets take pin
#1 of the J1 and soldered it to either of the outside terminals on the
toggle switch. Now solder a wire from J1's pin #4 to the remaining switch
terminal. With this simple wiring conplete; re-connect the 2160 board to
your computer's USB Port and "click" youe way to the "Calibration" Page.
Now flip the toggle switch from UP to DOWN and from DOWN to UP. Notice
what the calibration window shows. For this example, when you flip the
toggle switch UP, the #1 "RED" Button will flash for 1/4 second. But now,
when you flip the toggle switch DOWN, this time, the #2 "RED" Button will
flash. The #1 button will remain OFF.What are the possibilities to this
flashing? Using your FALCON or IL-2 Flight Simulator, you are now able to
program flight functions using this toggle switch. Lets say, you want to
be able to turn your Fuel Pump on and off. Inside your simulator program
"Settings" page, look for the function "Fuel Pump On" - "Fuel Pump Off".
With "Fuel Pump On" highlighted, just flip the toggle switch UP. The pulse
produced will be sensed by the flight simulator and saved inside memory.
Now with "Fuel Pump Off" highlighted, flip the toggle switch DOWN. Again,
the flight sim program will sense the 1/4 second pulse created by the 2160
and assign it to the function of turning off the fuel pump.
So now, by flipping the toggle switch
UP; the flight sim program will turn your Fuel Pump ON; when the toggle
switch is flipped DOWN, the fuel pump is OFF.
See the possibilities? The fuel pump
is not the only equipment that can be controlled by the 2160; Beacon
lights, Taxi Lights, Pitot Tube Heat On/Off. Even the Landing Gear can be
controlled (Up/Down). Any function that has an assignment as "Some
FUNCTION On"; "Some FUNCTION Off" can be controlled easily by the
2160.
Now you will see when I tell you that
the 2160 can control create 20 pulsed outputs but only 10 toggle switches
can be connected to one board. If you need more togle switches; all you
need do is to plug more 2160s into your computer's USB Port. No internal
conflicts will be created.
The Toggle
Switches
 SPDT Toggle Switches require 3
wires to operate. To make wiring of your switches as easy as
possible, the 2160 was designed so that 2 adjacent pins on the J1 and J2
connectors need to be shorted together to provide the 1/4 second pulse
associated with this closure. The second pair of J1/J2 pins are used for
the next Toggle switch. And so on.
The toggle switches used with the
2160 are standard Single Pole Double Throw (On - None -
On) devices and are available at many electronic supply houses on the
internet. Such as B.G. Micro For
your convience, Desktop Aviator also makes these toggle switches available
at reasonable cost. You can find these switches at:
Wiring the
Switches
With your purchase of the 2160, we
also provided twenty 2-pin female connectors. All you need do is to solder
three wires from the Toggle Switch terminals to the 2 pins of the female
connector. To the Left is an example of how to do this. Seeing that the
toggle switch is applying a "GROUND" to each of the 2160's control pins
via J1 and J2, the length of wire you use to solder the switch to the
2-pin connector is not a factor. It can be as little as 3 inches to as
much as 4 feet. If you wish to make the assembly two feet or more, it is
recommended that you use a "3-conductor wire". It has no effect on
the operation of the 2160, it just looks better.
Note that I have shown the 3-pins
used for the switch wiring as "A", "B" & "C". "A" and "C" are used as
the Control
wires, while pins indicated as "B"
are connected to the Center terminal on the toggle switch. This is
the Common GROUND (GND). As mentioned above the, the OD Numbered pins
of the J1 connector are the COMMON Ground, while, the EVEN Numberes pins
are called the Control pins. ALL Control pins on J1 will be
connected to the "A" and "C" terminals on the toggle
switches.
As for J2; all the EVEN Numbered
pins are connected to Common GROUND, while all ODD Numbered pins on J2 are
the Control pins. Placing the 2-pin conectors on J2, you must remember
that pins "A" and "C" are connected to the ODD Number pins, while pin "B"
is connected to any of the EVEN Numberes pins.
Make 9 more of these simple switch
assemblies or less if you wish.
Wiring Mechanical
Rotary Switches
I've shown you wiring a SPST and a SPDT Togle Switch to the 2160
board, but what about Mechanical Rotary Switches? No Problem. As you
already know, the flightdeck of a 737, 767, 747 ect also have rotary
switches to select between flight functions. Below is a drawing on how we
can wire the 2160 board to a 5 position Mechanical Rotary Switch (You can
also use switches with less then 5 positions or one with more then 5
but less then 10 positions).
  Just like the wiring of multiple Toggle Switches seen above, we can
use just 1 "Common" wire (GROUND) and 5 "Control" wires. Take a Rotary
Switch and turn it over to look at the side with the solder terminals. You
will see something similar to the photo
above.
The common terminal of the rotary switch is soldered to any of the
"Common" wires on the 2160's J1 Connector (see above), while all the
"Control" wires are soldered to the switches "select" output terminals.
That's all there is to it. If you have a rotary switch with more then 5
positions, just continue soldering wires to J1's remaining "Control"
pins.
When purchasing a Mechanical Rotary Switch for your panel, NO NOT
get one called a "MAKE BEFORE BREAK". This type of switch connects the
next terminal to its common pin before breaking its connection with the
previous terminal. You need to purchase a switch called a "BREAK BEFORE
MAKE".
So to Review: The Control Wires
from the J1 Connector are located at:
PINS 2, 4, 6, 8, 10,
12, 14, then starts up again at: 22, 24, 26
The Common Ground Wires from
the J1 Connector are located at:
PINS 1, 3, 5, 7, 9,
11, 13, then starts up again at: 21, 23,
25 The Control Wires from the J2
Conector are located at:
PINS 1, 3, 5, 7, 9,
11, 13, 15, 17, 19
The Common Ground Wires from
the J2 Connector are located at:
PINS 2, 4, 6, 8, 10,
12, 14, 16, 18, 20 HAPPY FLYING! The 2160 is an HID
(Human Interface Device), so the needed Driver Software is already
programmed into your computer. Your computer can sense more then one 2160
connected to its USB Port. 4, 5, 6 or more 2160s can be connected to the
computer via a device called a USB Hub. If you plan on connecting multiple
2160s to your computer, it is recommended that you purchase a POWERED USB
HUB. This device has its own external power supple. Using this USB Hub
will prevent any damage to your computer's power supply due to any
overloads.
