Wiring and Programming the Landing Gear Board
LED Wiring the 2650
Before we can install the .dll software, we need to build 3 LED Lightning Asemblies and the Toggle Switch. The 2650 requires 6 LED Indicator Lights; 3 GREEN and 3 RED. Just what the panels look like, is up to you. You might consider Square, Retangular or Round. It's up to you. The only important consideration is the voltage rating. The 2650 supplied a +5VDC from the USB Port to the 6 Gear Status Lights. So these lights need to be about 5 to 12 volts. That is the only requirement. Below, is a schematic of one of the assemblies. Each assembly has 1 GREEN and 3 RED LEDs. If you purchased the 12 inch Extension Cables (Available on our PARTS Page), just solder the WHITE wire from the cable and solder it to the (+) side of the GREEN Light; solder the BLACK Wire to the (+) side of the RED Light. The remailing terminals on the LEDs (-) are soldered together and the RED Extension wire is soldered to either one of the common (-) LED terminal. You need to build 2 more assemblies just like this one.
3-Pin Extension Cable (12inch - cut to desired length)
6 to 12V LED Indicator Light
3 Assemblies Required
1 - LEFT Gear
1 - NOSE Gear
1 - RIGHT Gear
Landing Gear Light Assembly
The LED Indicator Lights are a Polarity Sensitive Device. NOTE: that the (+) side of the LED is connected to the WHITE and BLACK wire of the Extension Cable.
The remaining 2 Terminals are connected together and soldered to the RED Extension Cable wire.
If you did not purchase the Extension Cables, ordinary #28 Stranded wire can be used instead. With the purchase of the 2650, we also included Four 3-pin Female connectors. Just solder the LEDs to these connectors using the Stranded Wire.

12 inch Cables are available
on our PARTS Page.
Before soldering to LED Indicator, the Larger of the 2 Extension Cable connectors needs to be cut off. The smaller of the 2 remains untouched. This is the side that will be plugged into the 2650 Board.

Toggle Switch Wiring
The next asembly is the Toggle Switch that is used to Raise and Lower the Landing Gear. For a simple but operational Landing Gear Lever, a standard Toggle Switch can be used. This switch can be either a SPDT (Single-Pole-Double Throw) or a DPDT (Double-Pole-Double-Throw). Below is a schematic showing how to wire the switch. Again, if you purchased the 3-pin Extension Cable, just follow the wire color. If not, you can use the #24 Stranded wire instead.

NKK Switch #S2AL can also be used
Whats nice about the 2650, you can make the panel as simple as you want or as elaborate as your pocketbook will allow. Below are 2 Landing Gear Levers I found on the internet just by using Google or BING search engines. Just look for Landing Gear Handles. You will be surprised just how many you can find. Below are just 2 of the many I found:
The only requirement is that thses handles MUST have some sort of switch (probably a Micro-switch) incorporated inside them. One set of contacts must close indicating that the lever is in the UP position and a second set of closing contacts indicating the DOWN Position.
For a setup; not to inexpensive or not to pricy, you can use a military style SPDT Toggle switch with a LOCKING handle. The locking handle comes close to the lever used with a Beechcraft aircraft. To lower the Landing Gear, you need to pull on the handle while forcing it to the DOWN position. For Landing Gear retraction, just pull on the handle and force it in the UP position.
A recommend switch for this application, is the NKK S2AL Toggle. A GOOGLE search can direct you to a sales location.

Locking Toggle Switch - PULL Handle OUT to unlock, then flip UP or DOWN
With all the sub-assemblies wired and ready to be installed inside your panel, now is a good time to consider just what the Landing Gear will look like. To the left is a recommended layout. It's a clean design and uses all available support of the 2650 boards. Note that there are just 3 LED Lights. You might consider using BI-Colored LED lights. When wired correctly, these lights will change from GREEN to RED or RED to GREEN depending on the location of the gears. Both colors are incorporated inside the same LED.

Putting all the components together is a Snap. The Toggle switch is connected to the 1x3 set of connectors on the left side of the board.
The 3 LED Asemblies are connected to the RIGHT side of the board (3x3 set of connectors) The proper orientation for each can be seen below.
