nanoScope is a small
battery powered tester for DMX512 and RDM. Built into a 5 pin XLR
connector with a translucent plastic case, nanoScope lights up in
different colors to report its findings.
The unit has two
modes of operation, selected by a recessed slide switch which also
doubles as the power switch.
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.
A flick of the switch
selects 'Analysis Mode'. Here nanoScope displays a sequence of
colored blips, that represent different attributes of the DMX512
signal. The sequence comprises one long blip followed by a train of
short blips.
The long blip will be
either green or red to indicate overall good or bad data respectively.
The train of short blips can contain:
Orange:
Break
Length
out of range, less than 88uS (an error)
Magenta: Mark
After Break (MAB), less than 8uS (an error)
Yellow:
Framing
error
(an error which may occur legitimately during RDM
discovery)
Red:
RDM
data format wrong (an error)
Pink:
Packet
too long, contains more than 512 channels (an
error)
Cyan:
Less
than
512 channels in data (informational)
Warm White: Non-Zero
start codes (excluding RDM) detected (usually informational
but
can
be an error)
Green:
RDM detected in data (informational)
Mint:
RDM draft detected in data (informational)
UV
Blue: RDM responses detected (informational)
Ice
Blue: DMX Test Packets detected (informational)
