GPS
Connect the GPS receiver's pigtail to a USB port on the SAM controller.
We recommend securing the USB cable to the SAM I/O harness:
1.
Ensure the SAM I/O harness' 2x8 Microfit is plugged in to the SAM
SIGNALS port.
2. Create a small loop a few inches from the USB connector at the end
of the GPS pigtail.
• Use a cable tie to fasten the loop to the SAM I/O harness wire
bundle. Leave enough slack so the USB connector so can plug
in and out of a USB port on the SAM controller.
3. Connect the USB cable to a port on the SAM controller.
