NEW TMB nanoScope DMX Tester


  • SOLD BY:
  • CONDITION: Brand New


The nanoScope is a DMX512/RDM tester built into an XLR connector.  It is a small battery powered tester for DMX512 and RDM that lights up in different colours to let you know what it finds.  

There are two modes, which you can select by a recessed slide switch which is also the power switch.  In 'Pixel Mode', nanoScope displays the first 3 DMX channels as an RGB mix.  This allows the tool to be used as a pixel mimic to provide confidence that the expected data is on the cable.  'Analysis Mode' displays coloured blips that represent different attributes of the DMX signal.  The sequence comprises one long blip followed by a train of short blips.  The long blips will be either green or red to indicate overall good or bad data respectively.
