4 Connector Pin Assignments

Harrier Power-Up Configuration Header

A 2mm, 16-pin low profile header located on side one of the PrPMC800/800ET provides the means to change some of the Harrier power-up configuration settings. The pin assignments for this header, along with the power-up setting with the shunt on or off, are as follows.
