pinouts of standard connectors I use.
CAIRO was pinched from http://www.familybest.co.uk/cairo/manual/data-card.html I use CAIRO-7 just to interface rigs and TNCs rather than running about in Hi-Viz.
It’s really, really, nice to see the tongue on the top if the red is on the RHS. Otherwise all sorts of bad stuff is gonna happen
