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:
§

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 hot-swapping 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.

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?
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.
