To setup a Trimble Ag132 to lock onto the OmniSTAR Satellite service:

1. Access the "DGPS CONFIG" screen
2. Press "Enter" key
3. Press "DOWN ARROW" key until "DGPS SOURCE" screen appears.
4. Choose "SATELLITE ONLY"
5. Press "ENTER" key
6. Press "DOWN ARROW" key until "EZ SAT:" screen appears.
7. Use arrow keys to set provider to "OMNI"
8. Press "ENTER" key
9. Use arrow keys to choose the correct satellite for your area
10. Press "ENTER" key
11. Press "DOWN ARROW" key until "SATELLITE FREQ" screen appears.
12. This will list the frequency of the DGPS satellite you specified in the EZ SAT: Field
13. Press "DOWN ARROW" key until "SATELLITE BAUD RATE" screen appears.
14. This should update to the Data Rate of the satellite you specified in the EZ SAT: Field
15. Press "DOWN ARROW" key until prompted to exit "DGPS CONFIG" or "Exit Menu" screen.
16. Press "ENTER" key to exit

OmniSTAR must then send an activation code over the satellite to the receiver. When received, it will display 'Reset by Omni Activation, Please hit Enter to continue.'

It can take up to 30 minutes for activation to be complete. It is important that the system is switched on until the receiver positions differentially.

1. Use "RIGHT ARROW" key, access the "DGPS SCREEN"
2. Press "DOWN ARROW" key
   
   First screen should display Satellite Frequency and S/N of the satellite signal-noise ratio and the strength of the differential satellite lock.
   
3. Press "DOWN ARROW" key and screen should display Omni as "SERVICE PROVIDER"
4. Press "DOWN ARROW" key and "DGPS DATA SOURCE" should read the correct "REFERENCE STATION ID"
5. Press "DOWN ARROW" key and screen should display AGE of DGPS and AGE of SYNC
6. Press "DOWN ARROW" key until "OMNI*SERVICE INFO" appears
7. Press "ENTER" key to access this screen
8. Press "ENTER" key to scroll through the screens for status of the OmniSTAR subscription activation noting "USER ENABLED" and next screen "STOP DATE", and some more information about Omnistar.
9. Use both ARROW key to display HOME SCEEN (press both arrow buttons three times at the same time).
   
   The HOME SCREEN will display on the top line, the type of position recorded. The letter G will be replaced as a D when the receiver starts computing differentially corrected positions. The second line should display the DGPS satellite frequency. This may take up to 30 minutes to indicate receiver is in differential mode even though the OmniSTAR activation shows enabled.
