What is Bluetooth?
Bluetooth wireless technology is an open specification for short-range wireless connectivity between different devices. Bluetooth wireless technology eliminates cumbersome cables in the field.
How many Bluetooth connections can I have at once?
MobileMapper CX supports point-to-multipoint connectivity, which allows up to seven mobile devices to simultaneously connect when within range. For example, users may connect to MobileMapper Beacon and receive differential correction messages while using a Bluetooth cell phone to communicate externally via the Internet.
Can I transfer files via Bluetooth to and from MobileMapper CX?
MobileMapper CX can send files to and download files from any Bluetooth client device. However, MobileMapper CX itself acts only as a host – not as a client. So MobileMapper CX can initiate file transfer to and from cell phones and network servers, but not to or from another MobileMapper CX.
Can I send or receive e-mails using MobileMapper CX?
Yes, MobileMapper CX provides an e-mail client called Inbox (tap Start > Programs > Inbox). You can configure this application with your ISP Host information, e-mail address, etc. Contact your ISP provider for these parameters. The Inbox utility also allows you to attach files to your e-mails, e.g., a file containing collected data. Note: in order to sent or receive e-mails you must first connect the MobileMapper CX to the Internet using the MobileMapper CX’s Bluetooth Manager and a Bluetooth-enabled cell phone. See the MobileMapper CX Getting Started Guide for detailed instructions on how to do this.
Can I use Wi-Fi on MobileMapper CX?
Yes, MobileMapper CX has a specific Wi-Fi driver implemented into the operating system. This driver provides compatibility to a Wi-Fi USB accessory from US Robotics (ref nr USB805421). This is the only Wi-Fi accessory that can be used with MobileMapper CX. For more details, please see MobileMapper CX Getting Started Guide.

How much memory does the MobileMapper CX come with?
The MobileMapper CX comes with three types of memory:
- RAM stands for Random Access Memory. It is very fast but “volatile” in that any program or data stored in RAM disappears when the computer is turned off.
- Flash memory is stored on an EEPROM (Electrically Erasable, Programmable Read Only Memory) where the programs are permanent but upgradeable.
- SD (Secure Digital) cards are flash memory cards that are very small and user-replaceable.
MobileMapper CX provides 128 MB RAM, 128 MB flash memory and a 128 MB SD card.
How do I confirm how much memory my MobileMapper CX has?
- To check RAM memory, tap Start > Settings > Control Panel > System. You will see a memory field near the bottom of the “General” tab.
- To check the flash memory, tap Start > Settings > Control Panel > Storage Manager and select USER MyDevice in the Store Info field. The remaining memory is displayed in the Capacity field.
- To check the remaining memory on the SD card, tap My Computer on the Desktop, navigate to the SD card, hold the stylus down on any blank space and select Properties on the popup option screen.
Why does MobileMapper CX display less RAM and flash memory than it from the actually has?
As with all computers, some of both the RAM and flash memory is used by the MobileMapper CX’s firmware. MobileMapper CX firmware consists of two components: a 24 MB operating system and an 8 MB “rescue image” (that is used in case the operating system is ever damaged). The operating system resides in the flash memory and is copied to the RAM memory when you turn the device on. The rescue image stays in flash, unless it is ever needed.
- The amount of available RAM memory displayed by the System screen is 128 – 24 ≈ 104 MB.
- The flash memory displayed by the Storage Manager is 128 – (24 + 8) ≈ 96 MB (for all units).
Can I use a larger SD card?
You may expand the SD card memory by inserting new cards or by using cards with greater memory. We have not heard of anyone having any troubles using a SanDisk card up to 4 GB - if they reformat it in a card reader using Windows Explore. Note: SDHC cards are not supported!
Can I attach a mass storage device to MobileMapper CX?
Yes, you can attach any mass storage device that has a USB connection. When you insert most USB storage devices into MobileMapper CX’s I/O module, they appear in Windows Explore as “Hard Disk.”
What type of USB data sticks does MobileMapper CX support?
MobileMapper CX supports USB 1.2 but not version 2.0. Some USB 2.0 devices also support version 1.2, but not all.

How accurate is MobileMapper CX?
MobileMapper CX provides real-time, sub-meter accuracy through DGPS corrections. The optional MobileMapper Beacon receiver provides beacon corrections to MobileMapper CX via Bluetooth technology.
Note: Sub-meter performance is subject to satellite and environmental conditions. See the MobileMapper CX datasheet for details.
Can I post-process MobileMapper CX data?
Yes. Some data logging applications running on MobileMapper CX record GPS measurements that can be post-processed by MobileMapper Office.
How do I set up the MobileMapper CX for real-time differential correction using SBAS (WAAS/EGNOS/MSAS) signals?
Run the DGPS Configuration program (tap Start>Programs>GPS Utilities>DPGS Configuration > Select Mode > SBAS and tap OK. With the receiver set to None (autonomous mode), Beacon (MobileMapper Beacon) or Other RTCM Source, the MobileMapper CX will not use SBAS corrections even if it receives them.
Where do I have to be in order to use SBAS corrections?
You should use SBAS signals only if you are in North America or the Northern Pacific (WAAS), Europe (EGNOS) or Japan (MSAS). Although you may pick up SBAS signals outside of these areas, the corrections are calculated using ground stations only in these areas. The farther away from these areas your receiver is, the more error you may be introducing to your position calculations.
If the receiver is tracking more than one SBAS (WAAS/EGNOS/MSAS) satellite, does it use corrections from both? If it uses corrections from only one, which signal is used?
If the receiver tracks two WAAS/EGNOS satellite, it will generate ionospheric corrections using data from both satellites. The "fast and slow" corrections are calculated using information from only the satellite with the greatest signal strength.
Where does the MobileMapper CX display the identification number of the SBAS (WAAS/EGNOS/MSAS) satellite being used for real-time differential correction?
The GPS Status application's Sig/Nav screen displays a status bar for each GPS and each SBAS satellite being tracked. The bars are labeled with the individual satellites’signal-to-noise ratio and they are color-coded. The status bars of GPS satellites that are being tracked but not used to calculate a position are colored gray. When a GPS satellite is being used to calculate a position, its bar’s color turns to blue. To differentiate them from the GPS satellites, the SBAS satellites’s status bars are always colored gray and are displayed on the far right of the screen. All satellite status bars are numbered with two-digit ID numbers of the satellites. WAAS satellites are identified with the numbers 35, 47, 48 and 51. The four EGNOS satellites are identified with the numbers 33, 37, 39 and 44. If you are tracking more than one SBASsatellite, the receiver will use corrections from the satellite with the strongest signal.
Even though I have RTCM corrections coming into my MobileMapper CX via the I/O module’s COM1 port, I don’t always get differentially corrected solutions. What can I do to fix this?
If you think that your MobileMapper CX is sporadically using RTCM corrections coming in on the COM1 port, do the following:
- Turn on the DGPS Configuration utility (tap Start > Programs > GPS Utilities > DGPS Configuration)
- Tap Select Mode > Other RTCM Source > OK
- Select COM1 in the Port selection field
- Tap Configuration to ensure the MobileMapper CX and the RTCM source are using the same communication parameters. Then tap OK on the Port Configuration screen.
- Tap OK on the DGPS Configuration Settings screen
- Tap Connect on the DGPS Configuration screen and then OK
- Turn on the GPS Status utility (Start > Programs > GPS Utilities > GPS Status) and make sure you see “Differential GPS” in the lower left of the GPS Status window
What is the MobileMapper CX’s default logging interval? Can I change it?
It is not possible to change the one-second default setting for the logging interval or the NMEA output interval in MobileMapper CX. Some mapping applications running on the unit allow you to set a logging interval that is greater than 1 second.
