Programming the
Trim Wheel Panel
Before Setting the switches to the required flight functions, the Trim Wheel Panel needs to calibrate the Two Potentiometers using the Calibration Window found on XP, Win 7 and Win 10 computers. For this, we will use the XP computer. Other Operating Systems will use the same procedure but the windows might look a bit diferent.

Plug the Trim Wheel Panel into an unused USB Port on the back of your computer. Power USB Hubs can also be used in there are no available ports.
When first plugged in, your computer will detect the TW Panel and load the appropriate Driver Software. This takes a few seconds. When loaded, we need to calibrate the potentiometers.

On the lower left hand side of the screen, you will find the icon:
Using your Mouse, click on it. When clicked, you will see another window pop-up.
Calibrating the Trim Wheel Panel
<=== Find Control Panel and click on it.
You will then be taken to a third window showing the computer functions available to you. Find and click on Game Controllers.
In the Game Controller Window, you will then see the Trim Wheel Panel as listed as
DTA Rotary Encoder" (or in later models "D/A Interface).
You might have noticed that DTA Rotary Encoder is the same listing used with our Models 2090 and the 2095A Encoder Boards.
This is true, we use the same computer chip in the TW Panel as we do in the Encoder Circuit Boards, but seeing that these chips have a unique Serial Number, there will be no conflicts between the TW and the 2090 and the 2095A Boards.
So there will be no problems connecting the TW Panel to the same computer using any number of 2090 or 2095A Boards.
In the lower right hand corner of the Game Controller window, you will see Properties.
Click on this link ===>
When clicked, you will now see the Properties window showing the 2 Potentiometers as Y Rotation and Z Rotation, along with the 6 Toggle switch.
Seeing that we have 6 single pole double throw toggle switches making use of an output configuration as our Model 2160, there will be 12
RED buttons that will light when we program these switches. The remaining dark RED buttons are not used with the TW Panel
In the upper right hand corner of the Properties window, click on Settings. This will being you to yet another window now.
In this new window, click on Calibrate ==>
<== You will then see the Calibration Wizard Window
Then click
And now the Calibration Window. The window shows that we will start the calibration on the Y Rotation potentiometer. This is the Large Trim Wheel on the Panel. In the lower left hand side of the Calibration Window, you will see a small box along side Display raw data. Click on the box. Now when you rotate the potentiometer, you will see the digital output generated by the panel's circuit board.
For this calibration, you need to rotate the TW pot all the way UP and then all the way DOWN. You will see the blue bar graph and the Raw Data change with the rotation. Do this rotation about 4 or 5 times. When complete, click on
When Next is clicked, you will then be brought to the calibration window for the Z Rotation potentiometer. This is the Slide Potentiometer. As before, slide this knob back and forth a number of times; then click Next
<== You will then see Calibration Complete.
Click on
You will then be brought back to the starting window, where you click on Apply.
The Calibration precess is now complete     ==>
Parts of the Trim Wheel Panel
The Trim Wheel Panel has 3 distinct sections: The Cessna style plastic Trim Wheel, Rotary Potentiometer, Slide Potentiometer and 6 Single-Pole-Double-Throw standard size Toggle Switches.
Cessna Trim Wheel
Slide Potentiometer
6 SPDT Toggle Switches
The Trim Wheel is a 4 inch Plastic wheel simulating the "Look" of a Real Cessna TW. When programmed, the TW adjusts the Up and Down attitude of your aircraft. Rotate the wheel Down will slightly increase the nose up attude of your plane. Rotating the wheel Up will slightly lower the nose of the plane; just like in the Real World.
The Slide Potentiometer can be programmed to preform numerious flight functions; such as Elevator Trim, Alieron Trim, Nose Wheel Steering (a Tiller), ect.
The 6 Toggle switches can be programed for any desired flight function as:
Landing Gear Retract
Landing Gear Extend
Landing Lignts on
Landing Lights off
Pitot Heat on
Pitot Heat off
Labels with an adhesive backing can be used
to identify the function of each switch
The panel measures 7.25 inches by 6 inches, thus allowing the Trim Wheel to be mounted inside GoFlight's larger #GF-AC Rack
It can be found here:
Programming the Panel  w/X-Plane
So lets start configuring the TW Panel for X-Plane operation. Here we will be using X-Plane v10.xx Laminar Research is coming out with Version 11.xx using a new User Interface. Although similiar in configuring the flight functions, v11.xx's setting window will be much different from what we will be showing here, but the flight function programming will be the same.
With X-Plane up and running, take your mouse and slide the cursor to the top of the computer's monitor. When there a menu window will appear.
Find and click on
When clicked, you will then see a sub-menu. Find and click on Joystick & Equipment
With that click, you will see the Axis setup window. It is here where we will select the operation function of the trim wheel and the rotary potentiometer.
In this window, you see 2 rectangular boxes showing
NONE along with a RED Bar.
Lets set the bottom rectangle to represent the trim wheel on the panel.
By clicking on the lower rectangle, a list of available functions can be seen.  At this time, we are interested in elev trim. Click on this function.
elev trim is now associated with the panel's trim wheel. Now you can rotate the TW up and down and see the GREEN Bar move with the rotation of the TW. With the rotation, the Green bar moves left to right and back again. You might have noticed a small box located just right of the Red and Green bars. These boxes need not be checked as for the TW Panel is wired in such a way that the proper rotation of the potentiometers is matched with the X-Plane software.
Now, lets configure the Rotary Potentiometer. Again as before, move the cursor to the top rectangular box, and click on it.
As seen to the left, the available functions are listed. This potentiometer can be configured to many flight functions. You might want the potentiometer to work as a Rudder Trim, Aileron Trim, Nosewheel Tiller, Prop, Fuel Mix.
All this and more can be configured to this controller. The choice is up to you.
The setting of the desired function is the same as the trim wheel.
When set, move the large round knob all the way from the left to the right and back again. Do this a number of times. Now, rotate the knob until the white line is centered with the large white dot at the 12 o'clock position.
Also, rotate the TW up or down until the GREEN Bar matches the same length as the lower bar. The results can be seen below.
Next, locate the Use THIS position as CENTER.  Then click. You have now set the midway point of the TW and the rotary potentiometer.

Programming the Toggle Switches
The Trim Wheel Panel comes with 6 Single-Pole-Double Throw, standard size Toggle Switches. These switches operate just like our Model 2160 USB Interface. So the flight function associated with each switch must as:      flight function on / flight function off
So with in mind, lets program 2 of the 6 switches so you can see when is involved. At the top of the settings page we've been using for the potentiometers, you will find the folder: Buttons: Adv
When clicked, you will see a full page showing 3 distinct columns. The Left will show check marks inside 6 Green boxes.
Center, will show the available flight functions. To the Right, you will see the Subfolder for the flight function you choose in the Center column. In the Left column, you will see 6 check marks in Green boxes. These check marks indicate the position of the 6 toggle switches. Go ahead; flip a few switches and notice how the check marks move from one box to another. So for now, lets flip all 6 toogle switches DOWN.
Left Column - Shows the position of the 6 Toggle Switches
Center Column - Shows a group of Flight Functions supported by X-Plane
Right  Column - Shows
a Sub-Folder group of Flight functions supported the Flight Function chosed in the Center Column
Lets set the function on SW1 Toggle switch. Flip the #1 switch DOWN; Click on electrical/. In the Center Column; click on APU generator off
Now, flip SW1 UP. On the Center Column, find and click on electrical/. Then click on APU generator on in the Right column.
You have now programmed the SW1 to turn your APU on and off with a flip of a switch.
This is only an example, should you need other supported Flight Functions, by all means, reconfigure SW1. With this example in mind, set the remaining 5 toggle switches as needed.
Programming the Panel  w/FSX
The Trim Wheel Panel is also compatible with FSX/FSUIPC, FSX-SE/FSUIPC and Pre3D. For this discusion, we will be programming the Panel using FSX. But first, a word about FSUIPC. FSUIPC is an add-on utility that allows the support of 100+ flight functions that the main FSX program does not. It is well worth downloading the program from:
For the full version of FSUIPC, you must purchase a license. It can be purchased directly from the FSUIPC website or on the FSUIPC programming window. From many years of experiance with FSUIPC, we find it is well worth the price and you should consider getting a copy if you are a serious minded flight simmer.

With the licensed version of FSUIPC loaded, and the TW Panel plugged into an unused USB input on your computer, run your copy of FSX.
Before we configure the Panel to FSX, we need to do a bit of house keeping.
The first window you encounter with FSX running is the
Free Flight. In this window, find and click on SETTINGS
When clicked, you will be brought to another window called Other Setings. On this window find and click on Controls
By clicking BUTTONS/KEYS, you will be brought to a window showing all available FSX flight functions and the FSX DEFAULT Keyboard and Joystick settings. As you can see from the example above; Brakes (apply/release) is already set to Joystick Button 01. This seting and ALL settings under the Joystick column MUST be Deleted. If not, and we program the Joystick Button #1 for a Trim Wheel Panel function, FSX as well as FSUIPC will preform the 2 finctions not the one we programmed. So use the Scroll Bar; find and delete any settings in this column.
To DELETE this setting and all other settings in the Joystick column, move your cursor to and click on the setting to be removed; in this case click on Botton 01. Then click on
Delete Joystick Assignment.
Now with all Default settings removed, we can now go to FSX and use FSUIPC to program the trim wheel. rotary potentiometer and the 6 toggle switches without any programming conflicts.
Now with FSX showing the cockpit of a Cessna 172, we'll start programming the TW Panel by first pressing the ALT key on your computer's keyboard. On the top portion of the screen, you will see the available folders. Look for and click on Add-ons
When clicked, you will then see the FSUIPC folder; click on this folder. By clicking on this folder, you will be brought to the FSUIPC window. Here, we will click on
Buttons + Switches
As seen below, another window will open up titled FSUIPC Options and Settings. It is Here where we will configure the 6 Toggle Switches
For this example, lets program the #1 Toggle switch to control the APU, just as before. So, flip the Toggle Switch to the UP position. In the FSUIPC Settings window, locate the Joy#/Btn# window. You will see some numbers appearing. The numbers seen here will difer from your setup depending on the number of USB devices you have plugged-in. So, in this example, we see Joy# 0 - 1 Btn#
Making sure, you have a check mark on:
Select for FS control and Include Project Magenta, lets program the #1 toggle switch to control our APU by first flipping the Toggle switch UP. Using the scroll bar,  look for and highlight Apu Starter.
Now, flip the #1 Toggle Switch DOWN. Again as before, use the Scroll Bar to find and highlight Apu Off Switch
Now lets program the #2 Toggle switch to control the Wing Leveler
Flip the #2 Toggle switch to the UP position; note that Btn# changes. Again, using the Scroll Bar, locate and highlight Ap Wing Leveler On.
Now with the #2 Toggle Switch DOWN, locate and highlight Ap Wing Leveler Off
That's it! Toggle Switch #1 is now programmed to control your APU
Apu Off Switch as seen in the Control window
This example shows you how to program 2 of the 6 Toggle Switches. The remaining 4 switches are programmed just the same way. You can set these switches to any supported Flight Function you need.
Now lets program the Trim Wheel and Slide Potentiometer
Now, going back to the FSUIPC Options and Settings window, find and click on Axis Assignment
You are then brought to a very crowded window. So before setting the potentiometers, it is good practice to first click on the Clear and Rescan buttons to set all perimeters to 0.
With 0s showing, rotate the TW Up and Down a few times and notice in the small window just under
Raw, you see the values from 16384 to about
-16191. This represents the rotational valus for the TW pot. 
Now we need to set the Upper and Lower limite on the potentiometer's rotation. So turn the TW all the way UP and click on From button. Then rotate the potall the way Down, then click on To
Down & To buttons
Now, lets program the TW. Rotate the Trim Wheel all the way in the DOWN. Using the Scroll button, locate and click on
Elev Trim Up
Now rotate the Trim Wheel all the way UP. Again, using the Scroll bar, find and click on
Elev Trim Dn
Now, this is the results of our efforts. Now Click OK to test the new Trim Wheel on your favorite aircraft.
Now, lets program the Slide Potentiometer. Getting back into FSUIPC's Axis Assignment, click on Rescan and rotary the pot from the left to the right a few times. The setting of the rotary potentiometer is the same as the Trim Wheel, but this time we can set the potentiometer to funcation as: Rudder Trim / Aileron Trim or even as Nose Wheel Steering (tiller). For those who need other functions, you can use Fuel Mix, Prop Pitch or Throttle if you so desire. Just about any supported flight function making use of a potentiometer can be configured.
