Topcon Positioning Systems, Inc. 7400 National Drive Livermore, CA 94551 GR-3 MANUAL ADDENDUM FOR DIGITAL UHF RADIO A. Configuring a Base Station’s Digital UHF radio modem in PDL Mode Note: To comply with RF exposure requirements, maintain at least 25cm between the user and the radio modem. For the GR-3 Digital UHF, the integrated radio modem provides TX/RX UHF communications between a Base Station and Rover. To configure the UHF radio modems, have the following ready: • • • PC running Windows 98 or later Modem-TPS 2.1p0 or later Serial cable or Bluetooth connectivity with PC 1. Connect the computer and receiver using an RS-232 cable or Bluetooth wireless technology. 2. Turn on the receiver. 3. Open Modem-TPS and select the COM Port the receiver is connected to. 4. Click on Connect. 5. On the Radio Link tab, set the following parameters for the base station’s radio modem in PDL protocol: P/N XXXX-XXXX Topcon Positioning Systems, Inc. 7400 National Drive Livermore, CA 94551 • • • • • • • Protocol – Select PDL w/EOT. Modulation Type – the modulation for PDL protocol is GMSK. Link Rate – the default link rate for GMSK is 9600 and is recommended for most applications. The link rate is the rate at which data is transmitted over the RF Link. Mode – The Radio Operation mode. The GR-3 Digital UHF can be set to Transmit and Receive in PDL Mode. Scrambling – Enable to provide more robust data communication over high interference areas Forward Error Correction (FEC) – enable to maximize data communication. With this parameter enabled, the rover radio modem has the capability to check and correct transmission errors (if any) in an incoming data stream. NOTE: FEC reduces data throughput by adding redundant check bits to the data stream. If using FEC with a differential messages format that produces a great deal of data, select a link rate of 19200 and a modulation type of 4-level FSK to ensure reliable radio communication between receivers. Channel – The current Transmit/Receive frequency channel in MHz Output power – Select the level of power for RF transmissions ranging from 10 mW to 1W. 6. After completing steps 1-5 in “Configuring a Base Station’s UHF Radio modem”, click on the Serial Interface tab. 7. On the Serial Interface tab, select a baud rate for the modem’s serial port.

Change this using the data collector software or Modem-TPS. The base is set into GSM mode. Change this using data collector software or Modem-TPS. The LED indicates that the receiver is set into Receive mode; however no radio link has been established Check to make sure that the base receiver is powered on Check to make sure that the base and rover receivers are on the same channel. Check to make sure the rover is not set into GSM mode. The LED indicates that the rover has established radio link with the base receiver, however it is not receiving RTK Corrections. Check to make sure that the base is tracking enough satellites. Check to make sure that the base is transmitting via a radio scanner or by setting up the base receiver with PC-CDU or application software. A fault condition has been detected.
