SIMRAD 44/54 Simnet problem

To all Quin Marine Simrad dealers.

XX44 and XX54 connected to SimNet
The XX44 and XX54 units are classified as Class
1 products for a SimNet system. This means that
you will be able to monitor and control the entire
network from the units. You can see which
products are connected via SimNet and which are
presently selected as sensors for the system. You
can also reset or make changes to the automatic
setup.

NMEA 2 port upgrade.

The 44/54 series connects to SimNet via the
NMEA 2 port and a special converter, the AT44
Active Tee. However, to cope with this high level
of data traffic, a very high baud rate of 38.400
baud is required for the interconnection. The
filtering of the port was originally optimized for
standard NMEA, 4.800 baud, and must therefore
be modified to meet the new speed requirement.


AT44 and software status.

The interaction between the XX44/54 series
products and the AT44 connected to a larger
SimNet system is very complex and have required
more work than anticipated. The very strict tests,
which are constantly carried out have revealed
minor, but important details, which have to be
corrected before the release.
Considering the known facts, we believe the
release will be ready in a matter of 2 to 3 weeks.

The Solution.

Units requiring Simnet connectivity must be
returned to us to change frequency dependant components.
Quin Marine Service workshop uses surface mount
rework technology and repairs are performed in
strict ESD safe environment approved by Simrad.
The work therefore must be carried out at our service center.

As computer boards are covered by warranty

this remedial work is free of charge.
