The Artistic Licence NanoScope is a powerful DMX512/RDM, battery-powered tester, built into a 5-pin XLR connector.
In 'Pixel Mode', nanoScope simply displays the first three DMX channels as an RGB mix. This allows NanoScope to be used as a pixel mimic to provide confidence that the expected data is on the cable.
In 'Analysis Mode', nanoScope displays a sequence of coloured blips, that represent different attributes of the DMX512 signal. The sequence comprises one long blip followed by a train of short blips.
