LEDs connected to the control lines are
usually
wired to light up when the control
line state is LOW. On the contrary, "power good" LEDs indicate the presence of
voltage on power lines (a "HIGH" state of sorts).
LEDs of Tibbit devices are usually buffered. That is, they do not impose any
significant load on the lines they are connected to.
There are no LEDs on "C" Tibbits.
Labeling
Each Tibbit device has a label which states this Tibbit's number and function.
A small 2D barcode (micro QR type) encodes the Tibbit number as well. This number
is a 4-digit code. First three digits in the code represent Tibbit number, and the
fourth digit indicates the device version (some Tibbits have more than one version
available).
For example, if the code is 0032 then this is
