„ Compressed ASCII
A geek-readable text format in which all commas and other punctuation are striped out all, and data is presented
in hexadecimal notation. Downloads much faster than uncompressed ASCII.

Compressed XMODEM
The most reliable way to transfer large amounts of data from the OMA-D560 system to a personal computer is
with the XMODEM file transfer protocol. Many communications programs (such as Hyperterminal) support the
XMODEM protocol.
If a data error occurs during a file transfer (due to line noise, for example), XMODEM will detect the error and
attempt to correct it.
Once you initiate an XMODEM data transfer, you have 30 seconds to tell your communications program to
start the XMODEM transfer. Downloading a compressed log file is also possible. The data compression
scheme used in the OMA-D560 system strips out all commas and other punctuation, and converts the data from
ASCII decimal to binary. The result is a data file, which is at least one-fourth its original size and transfers in
one-fourth the time of the original data file. To decompress the data to its original comma-delimited form, use
the DOS decompression utility “D-COMP,” which is included on the companion disk. The program will
request the name of the input file and output file. When the conversion is complete, you will be able to view the
data with any text editor or load the data into a spreadsheet program such as Lotus 1-2-3 or Excel.
