If you have an earlier Portsdown software version, please update to the latest version to provide these capabilities. Here are the full details.

	The Portsdown Software running on an RPi 3 will control a DATV-Express board directly via the USB port, without the need for any PC or other computer. The system gives a compact touchscreen interface to DATV Express and provides some of the features for DVB-S transmission that you would get using a Windows PC to control DATV Express. DVB-S2 and DVB-T are not available, although there is hope for DVB-S2 capability in the future.
