Gp330b pin out

Hath

Hi, does anyone have the pin out for a 330b? I have one with no cable and want to test it before spending the $ to get a new cable
 
Hath,

The pin out will be different depending on if you are using NMEA0183 or NMEA2000. Below is a link to the "Operator's Manual" for the GP330B.
See page 28 of 33 / S-1. This is the wiring diagram for the GP330B.

I’m sorry I’m either not understanding or not explaining myself well. I need to identify the pin numbers at the connector

Then use this document that is placed under the product at our website. it provides the pin numbers as you look at the connector end. It also shows the dimple that designates the number 1 pin.
