static setup is recommended. Addresses in the Network section must be entered in IPv4, dotted
quad, format.
All of these parameters require a restart for changes to take effect.
3.2.2 GPS Lock, Signal, and Current Time Information
At the top of the Time Server Configuration page is status information about the software
version in the Time Server and from the GPS module in the Time Server. The Firmware Version
is displayed and should be known before calling for support. The “GPS:” label will state whether
the GPS is locked to satellite signals or not. A “LOCKED” status in green letters is required for
operation. The “Signal Strength” line will give the signal strength of the top three satellites being
received. The possible range is from 0 to 99dB SNR. The time server will use as many satellites
as it can receive for the greatest possible accuracy. The current time is also displayed at the top
of the web page. The time zone is determined automatically from the browser settings. The time
is updated when the page is loaded (and GPS is locked) and thereafter is dependent on the
system clock of the web browser. Over time this value will drift based on the characteristics of
the HW clock in the browser hardware. Refreshing the page will update the time.
3.2.3 Use DHCP
Checking this option will tell the Time Server to ignore the other IP address settings and request
an IP address from the network's DHCP server at startup.
3.2.4 IPv4 Address
If the DHCP option is not being used, then the IP address of the unit set to by entering a standard
IPv4 dotted quad in this field. 192.168.1.15 or 10.10.0.96 are examples of acceptable formats for
this field.
3.2.5 IPv6 Address
This is the 128 bit IPv6 address of the device either statically entered of determined by DHCP.
The first 64 bits indicate the network address and the last 64 bits are user defined for their
network. Please note that a user should still setup the device as initially using IPv4. They can
then set an IPv6 address and/or view the IPv6 temporary. The web page can be accessed using an
IPv4 and/or IPv6. The time server will respond to Ping, Ping6, rdate and rdate -6.
3.2.6 IPv6 Link Local
This address is only valid for communications within the network segment (link) and is required
for stateless address auto-configuration. Neighbor Discovery Protocol is part of the IPv6 protocol
and uses stateless address auto-configuration. This address begins with prefix fe80::/64. The last
