Hi
For the viz key to enable up to 250k parameters on capture, is important that before opening the OnPC software you make sure that capture is communicating with the vizkey. Use the 3 led lights on the device as an indicator to know that the vizkey software is connected to capture. When the 3 leds are green, means there is communication.
Sometimes it doesn't work and takes disconnecting and connecting the vizkey again, to get the 3 leds to turn on.
Once that is ready, you can proceed to open the OnPC software and send up to 250k parameters. or the equivalent of 490 DMX universes
