Kongsberg EM 124 Maintenance Manual

Datagram formats

Different EM multibeams will use and log data on different formats.
The KMall format is the successor of the all format, and uses the file extension kmall.
Water column data can be logged in a separate file with extension kmwcd. The format is
a generic format with high resolution data and the structure of the datagram is designed
to make updates easier.
EM multibeams using KMall will be controlled and configured using the K-Controller
and can acquire and log data using SIS 5 or other third party acquisition software.
Older generation EM multibeams will not have support for the new datagram format or
use the K-Controller and SIS 5. This includes:
• EM 120/122
• EM 300/302
• EM 3000/3002
• EM 710
Newer generation multibeams will get support for both all and KMall format and will
have full compatibility with SIS 4, K-Controller and SIS5. This includes:
• EM 2040 Series multibeams
• EM 712
Next generation multibeams will only have support for KMall format, and as such will
require K-Controller and SIS5. This includes:
• EM 124
• EM 304
• Any future EM multibeams
The KM multibeam output datagram format is described in a Doxygen document,
a documentation generator writing software reference documentation, and can be
downloaded from the Kongsberg websites.
