power supply for RAP is also cut, no battery for RAP, definition for four core cable is:
Black：NMEA+， Blue：NMEA-， Red：24V+， Brown，GND；Black blue is signal wire,

3． You must choose one for main unit when many RAP are in parallel connection, pls do
set switch of main unit of SW DIP-4 to be 0000，and the rest for other RAP code must
be sole.，otherwise RAP cannot work normally. We suggest code is in order, and
