Dramatically Increase the realism of your Cessna 172 flight by adding outboard control panels in place of point and click Mouse or keyboard input. You can Add up to 20 Toggle and or Rocker Switches to your Flightdeck; Easily and Expensively. Unlike our 2040 INTERFACE that was designed exclusively for Push Button Switches; the 2120 has a built-in 1/4 second pulse generator, thus allowing standard SPST Toggle/Rocker Switches to be connected directly to the 2120 without the use of an outside circuit board. All pulses are created within the 18F2550 USB Chip code. Just connect the two wires from the Toggle Switch Terminals to the J1 and J2 male connectors located on either side of the 2120 board; Plug the 2120 into an unused USB Port; program with a aircraft function and away you go on your next, more realistic flight. To make the switch connections to the 2120 board easier, we designed the 2120 to accommodate twenty 2-pin Female Connectors. Just solder the switch to the two terminals, then plug the connector into the board. What can be Simplier? We also supply these connectors with your 2120 purchase. If you need extra, these Connectors can be purchased on our FS Parts Page located at: http://www.desktopaviator.com/Products/parts.htm or from the link below. The 2120 was designed for EASE of Installation and EASE of Programming. Even if you have limited Electronics Experiance or none at all, the 2120 is the Flight Sim Add-on for You! By adding multiple 2120s to your computer, you can add 20, 40, 60 or even 80 Toggle and Rocker switches for the Ultimate Flightdeck. Sense the realism of flipping a toggle switch to turn your 'Fuel Pump' On or Off; MASTER Alt, MASTER Bat; the uses are as ENDLESS as Your Imagination . . . With Our NEW! '20 Button Pulse Generator'    The 2120 will product one pulse when you flip the toggle switch ON. And a second pulse will be generated when the same toggle switch is flipped to OFF. Toggle switches can be programmed using FS2002, 2004, FSX  ASSIGNMENTS: Master Battery/Alt on-off Panel Lights on-off Fuel Pump on-off  ect.
