EM61-MK2A GPS Menu
Configure the EM61-MK2A GPS Menu on the TK6000.
1. Using the stylus, select the EM61-MK2A Set GPS Port Menu.
2. Select the EM61-MK2 GPS Input
Field and choose either Enabled or Disabled depending on whether or not GPS is used during the surveyt. When the GPS is disabled, a message stating GPS Disabled will be seen where the GPS coordinates would usually be in the logging mode.
3. Select a Com Port
in the Serial Port Field if enabling the EM61-MK2A GPS. COM2: is the default GPS Com Port. It is important to make certain that the GPS Port is different than the port specified for the EM61-MK2A data acquisition.
4. Specify the correct Baud Rate
for the EM61-MK2A GPS system. By default the Baud Rate is set to 9600, which is a fairly common setting. Baud Rates include 4800, 9600, 19200, 38400, 57600, and 115200.
5. Match the Parity
to the GPS’s parity. Options include No, Odd, or Even. The default is No.
6. Select the Data
Bits value that matches the GPS receiver. The default is 8 although it can be adjusted to 7.
7. Select the Stop
Bits value that matches the GPS receiver. The default is 1 although it can be adjusted to 2.
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.
9. After changing the EM61-MK2 Set GPS Port options, it is important to save.
Tap the OK Button to save. After selecting the OK Button, it is safe to push the X Button to exit. If the user exits without selecting the OK Button, the changes will not be saved.
