Installation and Configuration Guide
month in the Month list, and specify the time when the clocks move backward by
typing the hour in the HH field and the minutes in the MM field.
• To specify the difference between local and UTC time when Daylight Saving Time is
in effect, select the plus or minus sign in the Daylight Saving Bias sign list and type
the number of minutes in the MM field. The Daylight Saving Bias is the offset value
when a clock is set to automatically change according to Daylight Saving Time,
which means it is normally -60 (minus sixty minutes) in areas that practice Daylight
Saving Time and 0 (zero) in areas that do not.
7 In the NTP section, specify the IP address or hostname in the NTP Server 1 and NTP
Server 2 fields for the two network time servers that will be used for obtaining the date.
The NTP date must be always in UTC.
8 In the Time Synchronisation Settings section, set the Sync Mode to determine how
the SSP-3801 will synchronize its time to the time source:
• Continuously: Time adjustments are made continuously.
• At Specified Time: Time adjustments are scheduled for specific times. Type the
hours in the HH field and minutes in the MM field.
• Never: Time adjustments are never applied.
The Jam Sync button can be used at anytime to manually force the time
synchronization.
9 Click Save to apply all changes.
Configure the Reference settings
Use the SSP-3801 web interface’s Reference page to configure the card’s reference signal
settings. The Input Timing section displays the current state of the timing between the
reference signal and the SDI input signals. One of the following states is displayed for each
input:
• Locked: a valid SDI input signal is present and locked to the selected reference signal.
• Absent: an SDI input signal is not detected. This may indicate that no signal is present
or a problem with the cable is occurring.
• Mismatch: the SDI input standard does not match the configured output standard of
the card.
• Unlocked: the SDI input and the reference signal are not matching in frequency and
phase causing a vertical drift (the SDI input is free-running).
If the state is anything other than Locked, use the features in the Output Timing Config
section to synchronize the signals.
To configure the card’s reference settings:
1 Open and log into the SSP-3801 card’s web interface (see page 26 ).
2 From the menu, select Card Configuration > Reference.
