Cannot connect to the
sonar
• Verify the SIU is powered on
• Check that cables connections are free from corrosion and are
properly secured
• Check for bent pins on sonar cable
• Check for IP address conflicts. The network card on the PC should be
configured to 192.168.53.XXX where XXX is neither 100 (INS) nor the
sonar serial number.
• If using a network switch, bypass the switch and connect directly to
the computer to check for faults with the switch.
• Reboot PC wait 30 seconds, then power-cycle the SIU.
• Ping the sonar to check connection.
• Try grounding the SIU
WBMS is connected but no
IMU data is coming in
• Check cable connections and reseat if necessary
• Check for bent sonar cable pins
• Possible IP address conflict. Check network settings
• Windows Firewall is preventing connection, allow POSView access
through firewall. Can still be the problem if firewall is off.
• Possible damages sonar cable
• Try grounding the SIU
WBMS GUI does not
match description in this
manual or software not
performing as described in
manual
• Obtain the latest installation version from NORBIT support:
subsea_support@NORBIT.com and install.
IMU is connected but there
is no sonar connected
• Check cable connections reseat if necessary
• Possible IP address conflict. Check network settings
• The GUI and BathyProxy should be allowed in windows firewall.
• Try grounding the sonar
Surface SV sensor is not
connected or is showing
bad values
• SV sensor is not tightly secured to the head leading to faulty
connection; tighten up the SV probe to the head.
• Trapped air bubbles are changing sound speed. Stop the vessel to
allow bubbles to dissipate to see if reasonable values return. May
need to adjust mounting to reduce bubble formation
• Inspect the sensor for visible damage. Any distortion in the sensor
may cause bad readings.
• Check for foreign object stuck on sensor.
Sonar display is freezing,
and data packets are being
dropped
• May be due to heavy network traffic; run Task Manager to check if any
unnecessary programs/processes are taking up excessive network
bandwidth
• Bad switch, hub or cable. Replace.
• May need to manually update computer network card driver
Network disconnection
errors occur or data from
sonar and/or IMU is dead
• Check the sonar and/or IMU cables. Check that the connection at wet-
end is tight. If it has loosened then remove connection, clean threads
at both male and female fittings and apply a very small amount of
grease (O-Ring grease mentioned in this manual works well) then re-
tighten. If fingers are weak from cold, then use a tool but do not
overtighten!
Unable to get RTK
correctors
• Check COM port settings
• Check cable connections
• Verify IP address and mount point if using network solution
• Check radio link
• Try with Null Modem
• Check on a different unit to see if data is legible
