Thank you for your purchase of our Model 2130 PULSE Generator Junction Box.
If you have any comments or need additional information on the use of the
Pulse Generator Board, please write us at:
Since we introduced the 2040 USB/20 Button INTERFACE, I received many emails asking for a simple; less complicated way of wiring a standard SPST Toggle Switch to the board without building the Opto-Isolator H11AA1/2 pulsing circuit.
So, today, we introduce an easy to install USB Junction Box that creates the 1/4 second pulses that the H11AA1/2 circuit accompished but without the many hours or wiring and soldering.

Installing the PULSE GENERATOR is really no problem at all. The Model 2130 was designed to be installed on any unused USB Port. All you need do is to solder two wires from an RCA Cable to just about any SPST or SPDT Toggle or Rocker Switch. Plug the cable into the Junction Box. That's all there is to it.
The 2130 was designed for the Flight Sim Pilot with little or no electronic background.
It uses:

Wiring Toggle Switches
Below is a drawing on wiring a SPST Toggle Switch. Soldering just two wires is all it takes to get the 2130 up and running.  The wires from a shielded RCA Cable are soldered to the two pins on the Toggle Switch.
The connector side of the cable is pluged into any one of the 20 available jacks on the Junction Box. You can solder the remaining 19 switches in the same manner. Seeing that the toggle switches are conduction the COMMON GROUND, the length of the cable is not an issue.
Connecting the USB Pulsed Junction Box to Your Computer 
Connecting the USB Pulsed Junction Box to your computer is a simple matter. Find an unused USB Port on your computer and plug in the Junction Box. When pluged in, your computer will start to look for and load the required Driver Software. A small window in the lower right hand corner of the screen will indicate that New Hardware was found.
When the Driver software is loaded, you can click on the "START" icon (lower left hand corner of the screen). Then click on "Control Panel". Then "Game Controllers". When clicked, you should see something similar to the photo shown below.
The Junction Box is displayed as: "Pulsed Junction Box Model 2130".
Using your Mouse, Highlight this text and click.
A new window will appear as shown above. Here you can see 20 RED Buttons indicating the 29 Digital Switch Inputs on the 2130. These RED Buttons will flash for about 1/4 second when the appropriate Toggle Switch is flipped.
Depending where you connect the RCA Cables from the Switch Array to the Junction Box; any one of the 20 Buttons will light when you flip the Toggle Switch. Flip all 5 Switches to verify that 5 RED Buttons will light when the Toggle is flipped. The RED Button will light for about 1/4 second. This is Normal.
The Four RCA Jacks on the Bottom Row of the Junction Box provides +5VDC and GROUND and should NOT be connected to ANY Toggle, Spring Return Switch, ect. that places a short on these jacks. If any one of these Jacks are shorted to GROUND, you might damage your computer's Power Supply.
Wiring Toggle Switches to the Junction Box DOES NOT require you to connect any RCA Cables to these 4 Jacks.
ALSO NOTE: The Pulsed Junction Box CAN NOT BE USED with our Model 1070 Parking Brake, Model 2080 Carb Heat Controller or our Model 2070 Brake Pedals.
We at Desktop Aviator are developing a number of Add-on Modules that can be easily connected to the Pulsed Junction Box. Using the 2130, you can add our re-designed:
