Your How Many Strokes Terminal will work fine without an internet connection. Everything you need to run the Terminal is saved locally on the device. This includes Course and Tee data, but also screen saver images and videos. If the is no internet it will not be possible to update the Terminal with added information. We recommend that the Terminal is always connected to the internet with WIFI or a Network cable. If you are using Power Over Internet (POE) to power the Terminal, the internet connection is automatically delivered through the cabling (provided that the POE is connected to a router or switch on the other end)
