Button is tapped, the EM34 GPS program will be in terminal mode, displaying the GPS receiver output, the last NMEA command sent to the GPS receiver, and three command buttons: Pause/Go, Send, and Exit.

Every time the GPS records its location, information is sent and displayed in the terminal mode. If the user receives a message of “No Data,” the GPS settings or connection are not correct. The GPS monitoring can be stopped and restarted at any time using the Go/Pause Button. The Send Button allows the user to send a NMEA command to the GPS receiver. GPS parameters should be set using the GPS’s interface or manufacture’s software. However, if the user is familiar with the GPS’s system and NMEA protocol, he or she may use this button to give commands. It is important to note that not all GPS systems use NMEA protocol and some do not accept commands sent through serial cables. The Exit Button is used to leave the terminal mode.
