4. Frequently Asked Questions
4.1. Question: Where is the Antenna Reference Point (ARP) located on the
G2100?
Answer: The ARP is the bottom of the bolt on the underside of the G2100.
For more information see section 3.5 GNSS Antenna Offsets:
Figure 10: ARP Diagram
4.2. Question: Does the G2100 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.
4.3. 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.
4.4. 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
“G2100_Default_Config.txt” Follow the instruction to upload that file into the
G2100 in this manual.
4.5. Question: What are the correct specifications for a GSM SIM card in order
for it to operate with the G2100?
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.
