Most people own RJ45 (network) cables with one end that needs
cutting off. It is very easy to make a power cable from that "junk"
cable.
It's the same pin configuration as other loggers that use RJ45, like
Volkslogger. *
The timing ended up being a rush to get units to Uvalde. Perhaps
power cables will be supplied with all the rental units in the future.
There's already a circuit in my panel for the brick. Just need to
plug it in to the fused Anderson PowerPoles connector on the RigRunner
4008 labeled "FLARM", and find out where the antennas would like to
be.
