A non-AGI type GPS Receiver must have the following NEMA string
outputs enabled before a job is recognized:

If a GPS signal appears on the Guidance screen but a job cannot be
opened, check the settings on the receiver and verify this NEMA string is
selected.
Data output configuration when using an AGI receiver:

2. Select Enabled and press the Check button to accept.
3. The Baud Rate setting is set the same on the terminal and the receiver.
A minimum setting of 19,200 is required for 5 Hz GPS receivers. The
Baud Rate is the communication signal as defined by the manufacturer
of the GPS receiver.
