can be saved to the SD Card, and the SIM card allows cellular service with the internal GSM
modem.
The ports and the product label can be seen on the underside of the G3100. There are 3 ports:
two serial ports and one external power input port. Also located on the base of the G3100 is a
TNC connector for a UHF antenna, which is utilized by the internal radio. ALWAYS connect a
UHF antenna before powering ON the G3100. The threaded connector in the middle is a
standard 5/8” connector for mounting onto survey poles or accessories.

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):

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.

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 | 28
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.
Page | 29
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.
