User Manual
The current status of timecode available to the reference module is shown in the LTC Status
and VITC Status areas:
Status Icon Details
Valid Green Valid timecode detected at the input.
Phase Error Red SMPTE-12 specifies the phase relation between LTC and
video. If the LTC received does not match this alignment
window, the card will flag this error.
Frame Error Red
The time code must match the input reference frame rate. If
not, an error is flagged.
Absent Red No time code detected at the input.
Note:
The error detection algorithm uses the current reference format.
So, when using internal reference, all information extracted from the
input is out of phase, and the card may flag errors even if there are none.
To configure timecode logging
1 Select the Alarms tab
2 Select the checkboxes to send the indicated time codes (LTC, VITC) to the iControl GSM,
where it can be used by other network devices.
Note:
This uses network resources, so you should leave these boxes
unchecked if there is no need to use the time code in this way.
Alarms
The Frame Reference generates alarms that are sent to the GV Matrix controller card when
error conditions are detected. These alarms are used to set the control panel status display,
and the status icon in the top left of the iControl window.
To configure alarms
1 Select the Alarms tab
2 Click Alarm Config
The Alarm Configuration for Frame Reference window opens.
