The Holux M-241 GPS Logger enables real-time recording of coordinates and provides an easy-to-use travel logging service.
The M-241 can record up to 104,724 positions (as of firmware 1.12) with longitude, latitude, time and altitude.
The M-241 is a Holux Bluetooth GPS receiver with datalogger and LCD display. The design of the M-241 is based on the GPS solution from Media Tek Inc. (MTK GPS – MT3318) low-power chip architecture.
The log file can be transferred to the PC for analysis via a USB connection. Due to the standard format used, the log files can also be used by many online services, such as Google Maps, Google Earth, which are interpreted correctly.
Advanced NMEA Data Logger inputs NMEA data stream from GPS, navigation or any other NMEA compatible device directly into file, Excel, Access, any database or another Windows application. Advanced NMEA Data Logger provides real-time data collection from any device or instrument. Download GPS Tracker Data Logger for Windows to collect GPS data from various GPS trackers simultaneously.
You can also combine the recorded positions with the photos taken by your digital camera to provide a geographically accurate price history (GeoTagging). Thus, walking routes or itineraries can be tracked and documented.
On the LCD screen of the logger, the position information, movement speed, the free space for the recording and the date/time can be controlled directly at any time. The M-241 supports the distance and time recording modes, the kilometers and miles units.
Since the M-241 has a Bluetooth interface, even wireless connections can be realized without any problems.
File formats provided by the program (*.kml -Google Earth, Binary, GPX and *.txt NMEA file format).
The M-241 does not have a battery charging function. Powered by a Mignon (AA) battery, it can record satellite information for up to 12 hours. Various recording modes can be preset with the supplied program.
Using advanced technology, the M-241 can simultaneously track signals from up to 32 satellites. It records satellite signals every 0.1 microseconds and updates the position data every second.

The SensBox configuration is stored in the file FScxxxx.cfg file in the System folder on the SensBox SD card (xxxx is the SensBox serial number including leading zeros). If the configuration file is missing (e.g., new SD card), please create a empty file named FScforce.cfg and save this file on the SD card in the System folder. Insert the SD card into the SensBox, turn the device on, then off and the SensBox will automatically save the SensBox's current configuration to a file named FScxxxx.cfg
Use the Configuration tool below to set SensBox thresholds, parameters, settings and user-data and save as a configuration file. In the Configuration tool, File>Save will save settings to file named FScforce.cfg. Replace the FScxxxx.cfg file in the System folder on the SensBox SD card with the FScforce.cfg (this can be done directly to the SD card or via the USB connection).
