CN6: GPS Utility Connector
CN6 is the GPS Utility connector. It contains the GPS external reset, a buffered 1 pulse-per-second with a 7 ns maximum delay, the GPS
Event 1 input, and three GPS LED signals. All signals go through the EPLD so they are 5 volt tolerant and the LED signals are capable of +8/-
4 mA. Table 8 is the pin out of the Utility connector.
