Common Problems With Trimble Access and Other Survey Equipment
1. I plugged in an activated SIM card but my TSC3 controller won't connect to the network, it keeps giving me an error message saying "the answering modem has disconnected", what do I do?
SIM cards are set up to connect using the network ISP. Usually when receiving this error message, it means you need to enter the network ISP into your controller. In connection settings, edit your current connection by clicking on Edit and then navigate to the proxy field. This is where you will enter your network ISP. Contact your SIM card provider for ISP information. After this step is complete, this should solve your connectivity issues.
2. My GPS unit is “floating”, what do I do?
This probably means you are in an area that is not receiving good internet connection. Power cycle the unit and try again. If this does not work, go back to last point you collected where unit was working properly and test again to make sure the corrections match. If they do, then where your unit was floating is in an area with less than optimal signal strength.
3. The message "Connection failed" appears when you try to connect to a Bluetooth cellular modem?
Some cellular modems have different Bluetooth modes. If the mode is set to [Off] or [Automatic], a “Connection failed” message may appear. For a successful Bluetooth connection, set the mode to [On].
4. The message “Hardware Error –1” appears when you tap (Scan) in the (Bluetooth Device Properties) applet?
Clear, then re-select the [Enable Bluetooth] check box.
5. Bluetooth controller does not always find all the Bluetooth devices within the specified range?
A Bluetooth scan cannot always find other Bluetooth devices during the scan if there is another Bluetooth device scanning in the same area. If the device you are looking for is not found during a scan, wait a minute, and then scan again.
6. Initialization lost because of high RMS?
The receiver has discarded the current initialization because the measurement RMS has stayed too long above an internal cut-off value. This may be caused by too much pole movement when static, by a very bad environment, or by incorrect initialization. Check two or three points measured with the initialization that was lost. To do this, reinitialize in a good environment and re-measure the points. If the re-measurements agree within RTK tolerances, you can be confident that the initialization was correct and that a bad environment caused the loss of initialization.
7. "Cannot start streamed corrections" message in internet survey?
Make sure that the Internet connection you are using works outside of General Survey. Connect to the Internet, browse one or two websites, and use Google.com or similar. Leave that connection open and start a survey with General Survey. If the survey still fails to start correctly, there may be a problem with the IP addresses or port numbers in the style, or the base station providing the data may not be operational.
8. RTK survey will not work?
Check that you have selected an RTK Survey Style. Check that it is configured for RTK in the Type field in both the Base and Rover options. Check that the antenna is configured correctly in the Antenna Type field in Base and Rover options. Check that the radio is working and that it has been configured correctly.
9. "No Base Data" when Internet Surveying?
If you start an internet RTK survey and the No base data message appears, check the broadcast format, the initialization string for your modem, the IP address, and the port number of the base.
10. No grid coordinates?
11. Not receiving radio?
Check that all radio cables are connected to the correct ports and that the radio is switched on. Check that the radios are configured correctly in the Survey Style. Check that there are no obstructions (for example, trees or buildings). If there are, move to a place where the radio signals will not be obstructed. Check that the base radio is switched on.
12. Bluetooth operating range difficulties?
Bluetooth has an operating range of 10 meters (~33 feet).
13. No communication between instrument and the General Survey software?
Check the cables, connections and switches. Also check the power source to the receiver or conventional instrument. Note – Make sure that you have selected an appropriate survey style.
14. Conventional instrument will not connect?
15. Modem is not responding?
This message may appear after a Connecting to modem dialog has to be cancelled because it goes on indefinitely. If this happens, power cycle the modem. If you see the “Modem is not responding” message when connecting to an Enfora GSM/GPRS card, you may need to set the baud rate. To do this:
- On the controller, tap [Start / Settings / Connections].
- Tap the [Connections] icon and then select [Manage existing connections] under [My ISP].
- Select the connection name for the Enfora card that you created earlier, and tap [Edit].
- Tap [Next] twice and then tap [Advanced].
- Set the [Baud rate] to 115200.
- Tap [Ok] and [Finish] as required to exit the Enfora configuration
16. I am having trouble collecting a RTK/VRS point. What should I do?
The first thing to do would be to make sure that you are connected to the internet via either Wi-Fi, an active SIM card, or a personal hotspot. If you have a strong connection and are still having issues, make sure you are registered on the VRS/RTK network that you are trying to use. This is possible in the survey settings. The last thing to check if you are still having issues is that the network you are using is fully functional – contact your service provider. If you are still having issues, check out our basic setup instructions.
17. After exporting my data, my points are plotted nowhere near the actual location. What did I do?
This probably occurred because you (or a previous user) defined a coordinate system or projection before collecting (in the job file setup). If you are post-processing your data, it is best to leave this setting as no projection/not datum, that way it will record in lat/long and you can project your data later on during post processing with whatever datum and epoch is most useful for your particular project.
One way to optimize your time in the field is to set up a survey style. Survey styles allow you to set up pre-configured settings for different styles of collecting you may be doing in the field. You can customize connection settings, point attribute defaults, and more. This is similar to a data dictionary of sorts.
19. My controller says “unable to compute average” when I collect multiple points with the same point name. Is there a way to average points?
You can average to points, but not on the handheld. You must load the data into Trimble Business Center and post process them in order to compute an average. The reason you cannot average them on the handheld is so that the surveyor can review details about each point that is selected in the field, and make adjustments accordingly. If you do name multiple points with the same name, each collect will fall under the umbrella point name, and you can review each collect from there.
20. I accidentally deleted a job – how do I restore it?
Fear not. Trimble access will not purge deleted data until you restore the unit or delete the file while it is connected to the computer. You can restore a job by selecting Review Job and selecting the desired job. There should be a pop up allowing you to restore the deleted job and all of its contents.
21. I am having trouble downloading files from my handheld to my computer.
Make sure you have Windows Mobile Device Center installed on your computer and it is up to date with the current release. You also should make sure your computer is up to date with all updates. The handheld should be on when you are trying to connect to the computer. If you are having issues moving or viewing the files, they may have been corrupted somehow.
