4.5 Set Time

Clock/date display data can be derived from several sources; the system clock, NTP

synchronisation, LTC, or VITC from a chosen SDI input. The clock source is set by going to

the Set Time item in the Module menu. Here there are two tabs, Timezone and Time. The

timezone should be set to the appropriate region before adjusting the clock.

To set the clock source, go to the Time tab and select the desired source - Manual, NTP, LTC

or VITC. The setup procedures for each mode are:

Fig 20. Set Time.

Manual

In this mode the time and date of the system clock will be shown and

can be adjusted. Press the Get button to show the current time. To

adjust the time enter the new time and date in the appropriate fields

and then press the Set button. A battery on the CPU board ensures

that time data is retained should the unit be powered down.

NTP

In this mode the time is sourced from an NTP server (or multiple NTP

servers can be entered). Press the Add button to add a new server,

and enter the host name or IP address of the new server.

LTC

In this mode the time is sourced from the LTC input on the rear of the

frame. There is nothing to setup here; there just needs to be LTC

present for this to work properly. If no LTC is present then the system

clock will be used. (If LTC is present but later disappears then the

clock will continue advancing without any discontinuity).

VITC

Here the time can come from VITC that is present on any SDI input.

Select the chosen SDI source number that contains VITC. If no VITC

is present then the system clock will be used. (If VITC is present but

later disappears then the clock will continue advancing without any

discontinuity).
