B-binary-transfer
sends the DGPS data in hexadecimal format and NOT in the normal ASCII.
The receiving device, whether a PC or data logger, must be capable of receiving and capturing
binary data. While this worked well with 2 or 3 MB files, the Windows environment proved to
be unreliable for larger files. DGPS binary files may be much larger than 2 or 3 MB and in
those cases, part of the data was lost during the transfer even at low transmission rates.
The PC transfer method is highly advised.

PC-transfer.
GEMLinkW's Receive DGPS Binary Utility has been designed to safely transfer
the DGPS binary data from the memory of GEM Systems' magnetometers equipped with on-
board GPS and with post-processing option, to a file on the PC. Once initiated, the process
automatically checks for data integrity. Checksums of the transmitted and received data and size
of the files in bytes are available from the unit and the PC to confirm proper data transfer. Step
by step instructions are provided with the utility.
NOTE:
For this method GEMLinkW 2.4 or higher is required.
