System Configuration
Genlocking the Multiviewer
Genlocking the Multiviewer
To genlock the multiviewer with other plant equipment, a reference signal is required. For
this, certain requirements must be met.
• The Densité CPU-ETH2 Enhanced Ethernet Controller Card used in the Densité frame
housing the multiviewer must use firmware version 2.0.4 or higher. A controller with an
earlier version of the firmware cannot provide a time reference to the multiviewer card.
• If the time reference signal is provided by a Densité REF-1801 HD/SD Frame Reference
Module, this module must be configured as follows:
• An input reference signal must be connected to the BNC marked REF on the
REF-1801’s rear panel.
• The LTC source must be locked to the same reference signal.
• The reference source must be set to External (either from the card’s REFERENCE
menu or, in iControl, from the Input tab on the control panel for this card).
• In the case of a non-standard time code (for example, a count down time code, or a
time code that includes user bits with date information), the time code processing
mode must be set to Pass through (either from the card’s REFERENCE menu or, in
iControl, from the Input tab on the control panel for this card). The pass through
mode is available as of version 1.10 of the REF-1801 firmware.
• The URS generation mode must be set to Normal (either from the card’s REFERENCE
menu or, in iControl, from the Mode tab on the control panel for this card).
Notes
• If the REF-1801 is configured properly, the Status LED on the front of the
card will be green. Improper configuration results in periodical time code
glitches. Refer to the REF-1801 HD/SD Frame Reference Module Guide to
Installation and Operation. See
Related Documentation , on page 9.
• Using an LTC count down time code as the reference for a count up timer
is not yet supported.
