Not able to connect my Virtual CDU to my computer

Connection problems can happen due to one or more of the following causes:

1) Firewall blocking connection

Original text from: http://windows.microsoft.com/en-us/windows/communicate-through-windows-firewall#1TC=windows-7

  1. Open Windows Firewall by clicking the Start button, and then clicking Control Panel. In the search box, type firewall, and then click Windows Firewall.
  2. In the left pane, click Allow a program or feature through Windows Firewall.
  3. Click Change settings. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
  4. Select the check box next to the program you want to allow, select the network locations you want to allow communication on, and then click OK.

2) IP Address

Please check if the flight simulator computer IP address is properly configured on your tablet. This can happen when the option of “Auto Discovery” is not enabled.

Run VAInterface and roll the mouse over the VAInterface icon on the apps tray – this will show the computer’s IP address. Use this information to fill the IP Address field on the Virtual CDU settings Menu.

3) Port Conflict

There is a possibility that another application is using the same Virtual CDU port (port 9000). This can happen when the option of“Auto Discovery” is not enabled.

In this case you need to change the 9000 port information to another number (eg 9500) on the Virtual CDU settings area on your tablet or smartphone.

Go to C:Program Files (x86)Virtual AvionicsVAInterface and edit VAInterface.ini file in order to update the port numberaccording to:

PORT = 9500

4) Your WiFi router is locked an the IP address table is not being updated

In this case, reboot your WiFi router to force an update on the IP address table.

After the reboot, please check the IP address as mentioned on item 2.

5) Public network location type

Please make sure the network location type is Private and not Public. You can check the network location type in the Network and Sharing Center

How to setup Virtual CDU 737 with Prosim?

In order for VCDU to be able to communicate with Prosim, both Prosim and VAInterface need to be properly configured:

A – Prosim737 (main window)

  1. On the menu bar, click Config.
  2. Select Configuration and then the Drivers tab.
  3. Look for Generic COM Port/TCP driver and make sure it is enabled.
  4. Click on Advanced and then on TCP Communication – TCP Port , define the communication port (the default value is 8091). This port is going to be used at the VAInterface HOST configuration later on.

 

B – Prosim CDU

  1. Start ProsimCDU and then click on the window background (dark) with the right mouse button.
  2. Select Config option.
  3. On the Options tab, define the CDU role for this particular instance (Captain CDU or F/O CDU):
  4. At the Drivers tab, define the TCP port under Generic TCP Driver:

*You can choose the port number, just be aware that it’s not being used for another application.

It is possible to setup more than 2 CDU instances, but each one must have its own TCP port.

C – VAInterface

The VAInterface is done by manually editing the VAInterface.ini (located at the VAInterface installation folder) and filling out the following data structure under the [Prosim] tag:

[PROSIM] HOST_PORT=18749
HOST_ADDR=127.0.0.1
CAPCDU=0
CAPSERVERPORT=8092
CAPSERVERADDR=127.0.0.1
FOCDU=1
FOSERVERPORT=8093
FOSERVERADDR=127.0.0.1

Note: the values defined here are only didatic examples and should be changed for real configuration.

HOST_PORT – this is the communication port with Prosim737. It must be the same value defined on step A4.

HOST_ADDR – IP address IP of the computer where Prosim737 is installed. Usually it is the same machine where VAInterface also runs, so the local host address (127.0.0.1) is used. If you have each software in separate machines, then enter the IP address of the Prosim737 machine.

CAPCDU – enables (1) the conection with the Captain CDU. In case there is no Captain CDU instance, set this to 0 (zero).

CAPSERVERPORT – defines the Captain CDU TCP port. Must be the same port used in step B4.

CAPSERVERADDR – IP address of the computer where ProsimCDU is installed. Usually it is the same machine where VAInterface also runs, so the local host address (127.0.0.1) is used. If you have each software in separate machines, then enter the IP address of the ProsimCDU machine.

FOCDU – enables (1) the conection with the F/O CDU. In case there is no F/O CDU instance, set this to 0 (zero).

FOSERVERPORT – Define a porta TCP exatamente como configurado no item B4.

FOSERVERADDR – IP address of the computer where ProsimCDU is installed. Usually it is the same machine where VAInterface also runs, so the local host address (127.0.0.1) is used. If you have each software in separate machines, then enter the IP address of the ProsimCDU machine.

Also, on “Control Panel” it’s necessary to select the profile “ProSim 737”

*You can choose the port number, just be aware that it’s not being used for another application.

My Virtual CDU connects to the computer but does not update the screens correctly with PMDG 737 NGX

Please check if you are using PMDG 737 NGX version SP1C or SP1D.

If the version is correct, then this is likely caused by a known SimConnect issue in FSX. In this case, please try loading a default aircraft before the NGX.

This can also be the cause for the EXEC light not working.

If you still got this problem, download the latest version of VA Interface in our “Downloads” area

Download and place it on the folder you are currently running VAInterface from (VAInterface installation folder).
Run it by double clicking on the downloaded file name.

EXEC light doesn't light up

In order to have EXEC light working is necessary to enable SDK broadcast on PMDG 777. VAInterface tries to do enable it automatically, but due to Windows UAC (user account control) some users need to enable it manually. To enable it proceed as below :

1. Open 777X_Options.ini, usually located on “C:Program Files (x86)Microsoft GamesMicrosoft Flight Simulator XPMDGPMDG 777X777X_Options.ini“.

2. Check if  the text below is present :
    [SDK]
    EnableDataBroadcast=1

3. If not present or EnableDataBroadcast=0, please add the 2 lines above or edit it.

4. Probably, will not be possible to save it to same place due the same UAC reason that prevented VAInterface to do it automatically. In this case save it to another folder and copy back to this folder providing admin permission when required.
