Table of Contents
The G150 has two harness headers, which cover 10 pins each. The G150 comes with a single harness.
This covers powering the device plus commonly used IOs. If the application requires additional IOs - the second harness should be purchased when ordering G150s. Both harnesses are identical and can be used as either Harness 1 or Harness 2.
Specification:
- 1m long, 10 wire harness.
- 15 mm is pre stripped on the loose ends of the input (red), ground (black) and the ignition (white) wires.
- 24 AWG
Depending on which header slot the harness is plugged into, the pins are either defined according to Harness 1 or Harness 2. The silkscreen on the PCB indicates which header designates which harness. Commonly used I/Os are available via header 1.
In the image below, the harness is plugged into the header slot for Harness 1, as indicated by the white arrow on the silkscreen of the PCB.
