[CA] [CA11] Axiom RS125

[Bport7262]

I have an Axiom Pro 12 RVX (E70372 0970034) Software version 3.8.97.

Into the back of the machine through the NMEA2000 i have a STNG convertor (5 point) which is BLUE WHITE YELLOW WHITE BLUE with the following connections
BLUE - resistor
White - NMEA2000 to axiom unit
Yellow - RS150 GPS external antena
White - 12V power connection
Blue - resistor.

The Axiom unit can not recognise any external GPA antena.

I have also tried

BLUE -T peice (with 2 resistors) into white RS150
White - NMEA2000 to axiom unit
Yellow - RSeatalk cable into data input auto pilot and older GPS antena
White - 12V power connection
Blue - resistor.

Still the machine cannot recognise any external device.

The radar is connected wirelessly.
I have updated the software.

Should I be using a five piece connector instead of the STNG convertor?
