Symptom: A320/A220 LED's are lit with bottom LED flashing but the Intellislope or Integra monitor is displaying no GPS / RTK.
Cause: This is caused by the incorrect NMEA settings in the A220 / A320 that interface to both the Intellislope and Integra monitors.
Resolution: Use a PC and connect to the RS232 Serial Port on rover using either "Remote Control" software available for download via outbackguidance.com or "PocketMax 3.5" available for download via hemispheregnss.com.
The NMEA messages should be set as follows:
Intellislope: Baud Rate 38,400 - GGA 10 Hz - GSA - 1 Hz
Integra: Baud Rate 38,400 - GGA 10 Hz - GSA 10 Hz - VTG 10 Hz.
