DEVICE COMMUNICATION TROUBLESHOOTING
The following is a list of things to check, in order of
priority, if you are having problems connecting to
your display from Pro-FX Control.
1. Make sure the device is powered up.
2. Make sure the USB port is connected, and Win-
dows has properly loaded the drivers.
3. Make sure that the gateway.cfg file has been
properly installed per the instructions in this
document. Installation of a non-approved device
gateway may have overwritten this file.
4. In the Pro-FX Control Communication Settings,
select None for the Filter. Then rescan for the de-
vice. If something new appears, then it could be
that the device variant being used by your project
is different than the connected device. Pro-FX
Control will only let you connect to a device vari-
ant that matches the configuration of your project.
To switch to the appropriate device, right click on
it in the Devices project tree and select Update
Device.
5. Stop and start the gateway. Plug and unplug the
USB port.
6. Restart Pro-FX Control.
7 . Restart your PC.

8. In some cases, Windows will automatically assign
a high COM port number to the USB device. If
the device manager shows something higher
than COM20 then you should reassign it to some-
thing lower. Then restart the gateway and unplug
and plug the USB port.
9. Each time a unique device is connected to your
PC, Windows will provide two new COM port
numbers. In some cases, Pro-FX Control appears
to have problems automatically discovering the
device's COM port when the value gets too high.
In this case, there are two options:
From the device manager, click the COM port's properties, select
•
Port Settings tab, click Advanced and select a Com Port Number
that is below COM20. Then restart the gateway and replug the
USB device to ensure changes are applied properly.
You can alternately edit the gateway.cfg to manually assign
•
your device's COM port number. Open the gateway.cfg file
located in the Pro-FX Control install directory, and change the
line that begins with Com.0.Port. After making this change,
restart the gateway.
Note: After making this change, your installation will no longer
automatically detect other displays so this must be repeated for all
unique displays that are connected to your PC.
