EM61-MK2A Monitor GPS Output


8. If the Monitor GPS Output

Button is tapped, the EM61-MK2A GPS program will be in terminal mode, displaying the GPS receiver output, the last NMEA command from the GPS receiver, and three command buttons: Pause/Go, Send, and Exit.


Every time the EM61-MK2A 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 connections are not correct. GPS monitoring can be stopped and restarted at any time using the Go/Pause Button. The Send Button allows the user to send a command to the GPS receiver. GPS parameters should be set using the GPS’s interface and manufacture’s software. However, if the user is familiar with the GPS’s system and command protocol for the GPS system, the user 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.
