2.5 Communications Configurations
The V7 is a direct replacement for a V6 sonar with the exception of customers requiring Ethernet capability. This
will require either a proprietary Tritech ‘V7 connector’ or a compatible connector and cable harness. Arcnet and
Serial comms protocols are supported..
Seaking 700 Bathymetric sensors can be configured as Ethernet with Serial RS232/485 or as ARCNET and Serial
RS232/485 communication protocols. There is no ARCNET and Ethernet option.
See section on software setup for guidance on configuring your network.
Ethernet & Serial (RS232/RS485)
When connecting via Ethernet, the Bathy can communicate at 100Mbps while
returning environmental data.
If the Bathy shares it’s Ethernet link with other high bandwidth devices, such as
video cameras, it is recommended that a gigabit (or faster) network interface be
used to the surface to reduce possible network congestion.
Basic Ethernet Cable Setup
ARCNET & Serial (RS232/RS485)
The SeaKing 700 series can be set to form part of an ARCNET multidrop network
of sensors that are normally interfaced to a Surface Control Unit (SCU) through
an internal DA-15 ARCNET interface (AIF) port or through the DA-15 AIF port
on a SeaHub.
Normal communication with the Bathy head is via a customised version of the
ARCNET network system and requires a good quality balanced twisted pair.
There is also the option to run a single head from an RS232/RS485 connection.
Note
The ARCNET system requires termination resistors to be fitted at each end of
the umbilical. Please refer to Appendix A, ARCNET Termination for more details
of the termination requirements.
2.6 Ground fault Monitoring
The power supply within SeaKing subsea devices contain an electrically isolated
DC-DC converter. There is a small capacitive connection to the sonar chassis
which should not noticeably affect any impressed current ground fault indicator
(GFI) equipment.
