The Device Controller enables T-Pro applications to communicate with multiple external devices, e.g. footpedals and microphones.

If users experience connection problems the following should be checked:

Logs and temp file audio file storage

Starting from Device Controller v1.3.0, the local Windows users will no longer have write permissions for the application installation folder. Because of this security measure log, temp file and audio file storage location have been changed to use the local user folder: C:\Users\[userName]\T-Pro Device Controller.

RDP connections

The main way to use the Device Controller with a remote desktop is to install the application with the Virtual Channel options enabled.

Alternatively, if the Virtual channel is not working or is unsupported by the operation system, you can install the app with Enable external connections (Contact your administrator). If this is required, additional configuration will be needed, see below).

To make remote-enabled installations as robust as possible, please configure as follows:

Client-side:

Check the Enable external connections (Contact your administrator) checkbox
Check the Virtual Channel Plugin checkbox

Server-side:

Check the Virtual channel server installation checkbox.

This will ensure that in case of a Virtual Channel failure to connect, the application will be able to connect using an external connection(Web Socket).

Note: In case of device connection issues, please restart the RDP connection and re-plug the device before attempting to connect again.

Enable external connections (Contact your administrator) installation option.

This setting should only be used on the client side of the RDP-enabled setup.

When installing the Device Controller with the option ‘Enable external connections (Contact your administrator).’ enabled, the user must allow network access to the Device Controller. The following prompt will be displayed after the installation is complete and the app is started:

If the User does not have permission for these changes, the System Administrator must intervene at this step to allow access by clicking the prompt or adding these inbound Firewall rules for the Device Controller app to allow it to accept connections on TCP and UDP ports:

Note: this option and configuration will only work within a local network RDP connection. Allowing external connection through WAN is not secure.

Additional Troubleshooting

To check if the T-Pro app is connecting properly to T-Pro Device Controller, go to https://tpro.io using Google Chrome, press F12 (to open the developer console).

Follow the steps below to see IN/OUT messages in the developer console:

Click on the tab Network
filter by WS
select the name hid, and
click on the tab Messages.

Here, you will be able to see all communication between the browser and T-Pro Device Controller.

Retrieving the log file

The log files can provide useful information for troubleshooting.

Go to the following folder C:\Users\[YourUsername]\T-Pro Device Controller\Debug
Copy the files from the Debug folder and forward them to the support team.
