STATIC IP
To use a static IP address, de-select the checkbox for
[Automatically obtain network configuration from
DHCP/BOOTP]. You must enter the IP address, net mask,
gateway, primary DNS and also a secondary DNS.
Devices which have been assigned a fallback IP address of
“169.254.xxx.xxx” will be displayed in the main
WinDiscovery window with RED text, indicating a problem
with the configuration.
NTP CLIENT AUTHENTICATION SETTINGS
The Masterclock Digital Display technology can take
advantage of the MD5 Message Digest Algorithm, which is a
widely used cryptographic hash function that produces a
128-bit hash value.
IPV6 ADDRESSING (PENDING)
IPV4 ADDRESSING
The Masterclock Display NTP configuration uses IPV4
communications protocol using 128-bit addresses to
communicate with other Internet devices.
NTP OR TIME CODE CLIENT ADVANCED SETTINGS
From the NTP Client window, the [Client Advanced Settings]
button allows for the adjustment of additional
communication settings. Under most operating
circumstances it is not necessary to change these settings.
The factory-default TCP/UDP port for NTP service is: “123”
DISPLAY PROPERTIES
Control the brightness of the display
digits with a slider.
Choose from several other Display
Options including:
1. Type of input (Count, IRIG-B12, Auto
detect or Blank)
2. Clock mode (12- or 24-hour)
3. Count Input (takes one out of clock
mode and into count mode)
4. Whether leading zeroes are on or off
(during 24-hour time)
5. “Hold” symbol preference
6. UTC or local time display
7. NTP reference failure display settings
Port 123
Some NTP/SNTP servers will expect NTP clients to
operate on port 123.
If the advanced settings have been altered for
your clock and you begin experiencing difficulty
in getting your clock to synchronize to the NTP
time server, or the clock begins acting erratically,
try returning the advanced settings to the default
values: “123.”
