Once a connection is established, you can download all or some files to a computer or controller and then use the File Explorer feature in Topcon Receiver Utility (TRU) to manage the raw data files.
Troubleshooting •••••• This chapter will help you diagnose and solve some common problems that may occur with the receiver. Do not attempt to repair equipment yourself. Doing so will void the warranty and may damage the hardware. Check This First! Before contacting your local dealer or Topcon Technical Support, check the following: • Check all external receiver connections carefully to ensure correct and secure connections. Double check for worn or defective cables.
restores the receiver’s parameters to the factory default settings and erases the almanac and ephemeris files. This action does not delete data files from the receiver memory. • Erase all files by pressing the Power button for 15 to 20 seconds or by using File Explorer Delete All Files in TRU. This will delete all files stored in the receiver’s nonͲremovable memory card. If the problem persists, see the following sections for other solutions.
Troubleshooting Receiver Problems The following are some of the most commonly encountered receiver problems. The receiver cannot establish a connection to a computer or external controller Cable specific problems: • The cable is not properly plugged in. – Unplug the cable, then securely and properly reconnect it to the receiver. • The cable is damaged. – Use an undamaged cable. Contact a dealer to replace the cable. • The USB driver is not installed.
• The corresponding receiver options may be disabled or expired (L1/L2, GPS/GLONASS must be on to track satellites). – Order a new OAF with the desired options activated to enable or extend validity of the corresponding receiver options. Contact a dealer or visit the Topcon website for details. – Refer to the “Receiver Managing” chapter of the Topcon Receiver Utility (TRU) Reference Manual for a detailed description of options.
• a. Connect the receiver to a computer and open TRU (see “Connection” in the Topcon Receiver Utility (TRU) Reference Manual). b. In TRU, connect to the receiver. c. On the TRU main window, choose Receiver Settings Ports. d. • • DoubleͲclick on the port to be configured and make sure the input mode of the Rover matches the format of the Base output mode (i.e. RTCM3). Poor satellite geometry (PDOP/GDOP values are too high).
• • • receiver transmits differential messages to the modem and vice versa. – Change the modem’s baud rate. The Base and Rover modems use different radio link parameters. – Configure the Base and Rover radio modems according to the procedures listed in the TRU Reference Manual. The distance between the Base and Rover is too far. – Close the distance between the Base and Rover. – Use repeaters to increase radio coverage. There may be a source of radio interference that disrupts radio communications.
The following are some of the most commonly encountered error messages and other problems. TRU error message: Can’t find receiver • The receiver is turned off. • • • • • – Ensure the receiver has power and is turned on. Bluetooth is not turned on; the BT LED is off. – Reset the receiver to the factory default settings by pressing the Power button for 10 to 15 seconds. – You can also turn on power to Bluetooth using TRU. To do this, on the TRU main window, choose Receiver Settings Bluetooth.
Change the Input Mode for the Bluetooth serial port used for connection to cmd. Troubleshooting c. This is the most common cause for this error message. Use TRU to double check the settings for the connection port. TRU error message: Open COM# port failed: Access is denied • Another application uses the computer port dedicated for connection. – Close the application, and then reͲconnect. – Connect the receiver via another, unused computer port.
If the settings are changed for the Bluetooth module, remove it from the list of discovered Bluetooth devices using the Bluetooth manager program (supplied with the device used to manage the receiver). b. Repeat the search. Troubleshooting a. TRU Problems The following is the most commonly encountered TRU problem. TRU cannot connect to the receiver • The receiver is turned off. – Ensure the receiver has power and is turned on. • If using a cable, the cable’s connectors are improperly attached.
• Use a clean cloth moistened with neutral detergent or water. • Never use an abrasive cleaner, ether, thinner benzene, or other solvents. • Always make sure the receiver is completely dry before storing it. Dry any moisture with a soft, clean cloth. Getting Customer Support If the troubleshooting hints and tips in this operator’s manual fail to remedy the problem, contact Topcon Customer Support.
