NTP Service
tab.
b Make sure that the IP addresses and synchronized device are in OK mode

• The master clock is found at IP address 10.124.45.200 (example).
• The NTP server will also update the EK80 Processor Unit clock.
• In some cases a motion reference unit (MRU) providing the KM Binary
datagram does not act as the vessel’s master clock. You must then follow
the instructions of the MRU manufacturer to synchronize the MRU to the
Ship Master clock.

Troubleshooting the Network Time Protocol (NTP) service
The Network Time Protocol (NTP) service may in some cases malfunction, or even stop.
Context
The EK80 installation program adds a firewall rule to allow for NTP communication. If
the EK80 issues messages related to missing time synchronization between a motion
reference unit (MRU) and/or ADCP hardware synchronization, the problem is most
likely related to the firewall.
Procedure
1 Check the firewall settings on the Processor Unit.
One reason for NTP synchronisation problems may be a firewall or port filter that
inhibit the communication. Check the firewall settings in the Control Panel.
