4. Factory AsteRx2e receiver Settings

The instructions below should be used to reconfigure an G3100 back to PENTAX Default. This is the #1 method for resolving problems with the G3100’s operation, and should always be executed before contacting PENTAX support.

Reconfiguring the G3100 back to PENTAX Default sets the unit as a Rover, Message Type: RTCM v3.1, Logged Data Type: SBF. The two ways of accomplishing factory settings are:

1) Upload appropriate

[1]

PENTAX default script using RxControl

2) Typing the commands in line-by-line.

[1]

The G3100 model is determined by the serial number found on the bottom of the receiver.

4.1. Uploading a script/text file using RxControl

A text file with factory reset commands is included on the CD shipped with each new G3100 unit. The file can also be downloaded from the PENTAX website:

§ G3100 (2XXXX): G3100 Default Config.txt

4.1.1. From the RxControl File menu, select “Upload script”.

Figure 10: Upload Script

Page |

4.1.2. Select the prepared text file from the PC and click Open.

Figure 11: Script File

4.1.3. The G3100 has been successfully reconfigured to the PENTAX Default when the commands appear in the bottom left corner of the main RxControl window. The commands and return messages will populate the expert console.

5. Frequently Asked Questions

5.1. Question: Where is the Antenna Reference Point (ARP) located

on the G3100?

Answer: The NGS ARP is the bottom of the bolt on the underside of the

G3100.

For more information see section 3.4 GNSS Antenna Offsets:

Figure 18: ARP Diagram

5.2. Question: Does the G3100 L1 vertical offset need to be added to the measured height to the bolt?

Answer: No. Data collection software adds the vertical offset

automatically when the appropriate antenna type is selected.

5.3. Question: How do I know which battery I can remove without having operations interrupted?

Answer: Use the battery status indicator in data collection

software to confirm which battery is “ in use” before hotswapping batteries.

5.4. Question: How do I configure a unit back to the PENTAX factory defaults?

Answer: Located on the PENTAX CD there is a text file called

“G3100_Default_Config.txt” Follow the Factory AsteRx2/AsteRx2e receiver Settings in section 3 of this manual to upload that file into the G3100.

Page |

5.5. Question: What are the correct specifications for a GSM SIM card in order for it to operate with the G3100?

Answer: There are three key items that must be specified to get

the correct GSM SIM card and service from your cellular service provider;

GSM SIM card (not UMTS) Data service only No IMEI number (i.e. no associated hardware/handset)

SIM cards that had one or more of the above 3 features

incorrect did not work. In the USA, AT&T and T-Mobile provide GSM SIM cards that have been used successfully with the G3100.

5.6. Question: Why am I not receiving GLONASS corrections?

Answer: You must first verify that the base station transmits

GLONASS corrections. The G3100 first utilizes GPS satellites to get to RTK Fixed status. Then if more than 2 acceptable GLONASS satellites are available, RTK Fixed GPS+GLO RTK status is achieved.

5.7. Question: Why is my radio not receiving RTK corrections?

Answer: Check Base Station Configuration. Make sure that Base

Station receiver is set up and using more than 5 common Satellites. Check Rover Configuration; make sure that it is configured to use the correct RTK format corrections. Both Base Station and Rover must use the same UHF Radio Channel and same correction format.

5.8. Question: How do I know which message type to select RTCM V2.3, RTCM V3.0, CMR, or CMR+?

Answer: Base stations transmit different messages types. It is

important to confirm what message type(s) the base is transmitting so the Rover can be set accordingly.

5.9. Question: How can I verify the Windows Mobile® version my hand held device is operating on?

Answer: In the main view of the controller, select the Start Menu,

next click Settings Menu, then select the System tab, lastly select the About icon which will display the Windows Mobile® version.

5.10. Question: I can’t connect to the G3100 via Bluetooth®, why not?

Page |

Answer: Make sure that the serial cable (SER1) is disconnected.

The serial cable takes precedence over Bluetooth® connectivity, and because of this Bluetooth® is unable to connect when the cable is attached. Also verify the Bluetooth® is ON/Visible on the controller. Lastly, uploading the PENTAX default script (using RxControl) will reset all COM ports and often fixes Bluetooth® connectivity.

5.11. Question: I noticed that the units get extremely hot at the top, what effect might this have on any operations?

Answer: The G3100 is designed to operate reliably from -20 to

+65 °C. Like most manufacturers, we test beyond that limit to ensure we can operate at the published extremes.

5.12. Question: How do I update the G3100 to the latest firmware version?

Answer: Get the latest firmware release from TIAsahi. Connect

the 5 pin controller serial cable (SER1) to the bottom of the G3100, connecting the DB9 side of the cable to a PC’s RS232 serial port. Power on the G3100 and open RxControl. Once connected to the G3100 click the tools tab and select upgrade receiver. Click Ok to close connection. Then click “Next” in the RxControl Upgrade Wizard. Next select the COM port used for the connection between the G3100 and computer followed by clicking “Next”. Locate the appropriate SUF file, and click “Next”. Then select “Upgrade”, and proceed with any other on screen directions. Once completed, firmware version can be verified in the “Help” tab of RxControl in the “Receiver Identification” menu. It can also be checked using SurvCE and FIELDGenius.

5.13. Question: My receiver will not respond to commands, why not?

Answer: A setting in the G3100 may have been incorrectly set

causing a disruption in communication. Power the unit off, remove all power sources, turn the unit back on. After the unit boots, perform a hard reset and upload the default script.

If you are using a USB-Serial adapter, the adapter may not be

compatible with the G3100. If possible connect directly to a physical COM port on the PC. Otherwise, adapters using prolific drivers have been found to work more reliably.

5.14. Question: How can I tell which G3100 model I have?

Answer: The G3100 model is determined by the G3100 Serial

number found on the bottom of the unit.

5.15. Question: I cannot connect using the GSM modem, why not?

Answer: Be sure that you are selecting the G3100 model in your

data collection software. Selecting the wrong model version will cause communication issues with the GSM modem.

The G3100 GSM modem requires that Flow Control be enabled

on the system. If this was previously turned off it will need to be re-set. You can accomplish this by re-uploading the default script to the receiver or by sending the command SCS,COM2, , , , RTS|CTS using data collection software or RxControl.
