HOW TO get your Tacan channels working with the PSCockpit System

If you are planning to use 7 segment displays to display the UFC and Aux Tacan Channel you have tree options in the PSCockpit system:
- Using (4) 7seg. displays.
- Using (3) 7 segment displays and (1) 14 segment alphanumeric display
- Using 4-Digit 5x7 Dot Matrix Alphanumeric Intelligent Display SLG2016

And the last option, only for the Aux Comm Tacan Channel, using the Cherry pushwheels.

Option 1: Using (4) 7seg. displays.

Configure your 7s displays as usual in the IO Layout:

Select the correct Id in the F16Model page by clicking on 7S Display and make the configuration of your 4 digits as shown in the picture:

Now, when you run your sim ,the PSCockpit software will display the Tacan channel in the first 3 digits of the display and the last one will show a 0 when the band X is selected in the sim and will show a 1 when the band Y is selected in the sim.

Option 2: Using (3) 7 segment displays and (1) 14 segment alphanumeric display

To use this option you must try to get 14 segment displays with the same dimensions that the 7 segment displays, the same colour and the same brightness. This could be difficult to find.

Remember that all segment display have to be Common Cathode as well as the 14 segment display.

I have found the Kingbright PSC39-21GWA is a little bigger that the Avago HSDP-7803 and probably can be use it. But, sorry, I didn’t try it.

As before, configure your 7s displays as usual in the IO Layout, this time using a 3x7 Seg. Display.

Now we have to connect the segments. We are going to use to a 5VDC power supply. To limit the current to 25 mA we will use a 120 Ohms resistor. This resistor can be change a little 80-160 Ohms to get the same brightness as the rest of the 7 seg. displays. The wiring will be the following:

The resistor R1 might need also some adjustment to get the same brightness as the others.

Now, if we activate the X band output, will see an X on the display and if we activate the Y band output, will see and Y on the display.

The X and Y band outputs can be selected on the PSCockpit Software in the F16 Model page (Lights) as shown in the picture:

Option 3: Using 4-Digit 5x7 Dot Matrix Alphanumeric Intelligent Display SLG2016

Proceed as a normal 4-Digit 5x7 Dot Matrix Alphanumeric Intelligent Display SLG2016 like explained in the following post:
http://psfalcon.blogspot.com.es/2012/08/how-to-use-5x7-dot-matrix-alphanumeric.html

Option 4: Using Cherry pushwheels.

The Cherry pushwheels are selector switches with very small dimensions for front-mounting. The ones we are going to use are the PE series with 10 switching positions BCD.

I have selected the Cherry PE C - A - 3 - 4 - 00 (4 digits BCD complete with end caps) and 3 spacers 609-0760 which gives me a total dimensions of 24x45 mm.

You may want to order also (2) stops 609-0013 to limit the first and last digit of your auxiliary tacan channel. Look at the Cherry catalogue for other options as illumination.

To set the Cherry pushwheel for realism you will have to dismantled under your responsibility the first digit to change the number strip to 0-1-0-1-01-…. and X-Y-X-Y-… for the last digit.

To connect each of the pushwheel to the PSCockpit System, go to I/O Layout page and select “16 to 4 BCD” inputs in a location with 4 consecutive inputs free:

We have to wire each of the pushwheel as shown in the picture according to the pins selected in the IO Layout page:

To test the Cherry pushwheel click on test and verify that the inputs are ON according to the following true table:

Once we have tested each of the pushwheels we have to put the commands to be sent to the sim. For this, go to the Commands page, select BCD, select the correct ID for each pushwheel and fill the matrix with the command that changes the Aux Tacan channel in your sim, in this case, for digit number one, Shift+F1.

If you want to get your Aux Tacan channel in synchrony with the sim, go to F16 Model page, select Special I/Os, fill the data of the Aux Tacan channel and check the checkbox “Aux Tacan Synchro”:

Now, when you enter the cockpit the tacan channel of the sim will display your cockpit tacan channel. Yihaaaaaa.

HOW TO use 5x7 Dot Matrix Alphanumeric Intelligent Display SLG2016

The SLG2016 is a four digit 5x7 dot matrix display module. The integrated circuit contains memory, a 128 ASCII ROM decoder, multiplexing circuitry and drivers. The character set consists of 128 special ASCII characters.

Display interconnection is very straightforward, look for the spec sheet.

In the PSCockpit System you have to connect 10 outputs from the 16 or 40 I/O boards directly to the diplay inputs as shown in the figure in green. All other pins have to be connected as per its specification sheet.

To select this type of display in the PSCockpit system, go to IO Layout page and select the SLG2016 from the Function dropdown list. The chosen output must have nine more free outputs. Once accepted, you will see which output has been assigned to do the correct wiring:

------------------------------------------------------------------------------------------------------------------------
It is possible to group (2) or (4) SLG2016 displays in a row with adding just one wire more for each display.
You can select this grouping from the dropdown list:

------------------------------------------------------------------------------------------------------------------------

To test the display, once in Test Mode, click on the “+” symbol and you will be prompted to enter the desire text to be displayed. Once you accept, the display will show the text.

To configure the display to run from your favourite sim, go to F16 Model page and proceed as a normal 7 Segment display like explained in the following post:
How to 7-segment displays

Edited on April 11th, 2016
-------------------------------------------------------------------------------------------------------------------------
For the SLG2016 the above formatting should be 4 digits:

Once you have defined the length of the values you are going to use in the SLG2016 displays, if you use the SLG2016 grouping options (x2) or (x4), you have to group also the values of the sim you will be sending to the displays.

This grouping configuration is made in the 7 Segment Displays menu of the Airplane Model page of the PSCockpit Software doing the following procedure:

1. Select the SLG2016 slot to save the configuration with the dropdown list. There are a maximum of 10 slots.
2. Select the expander address where the SLG2016 are connected
3. Click on Address and select the SLG2016 group. The first pin address will appear besides the Address label, the free digits will be updated and a drop down list will appear at the end of the frame.

4. Select the first magnitude that will appear in the left most digits of the SLG2016 group. Once selected the magnitud the dropdown list will change to orange where you can select one of the operations available to change the magnitude value (=, *10, *100,....,/10, /100,...).

5. You may repeat the procedure until you have filled all the digits available.
6. At the end of the frame you will see the list of the magnitudes of the group with the digits in brackets and the operation that will be made to each of the magnitudes.
7. You can use the Back command to delete the last magnitude from the list.
8. You can use the Clear command to delete all the list.
