Outline of 05P0606 circuit
The 05P0606 board –66 and above is modified, so that the remote signal distribution
circuit and the NMEA distribution circuit have an individual grounding.
The * (bold letters) and dotted lines are the circuit before modification.
CR9 : “ON” while power is supplied.
CR6 : “Blink” while NMEA signal outputs.
