Model 5601ACO2 Automatic Changeover Unit
Page 1-2 Revision 1.2 OVERVIEW
In the event of a changeover occurrence, it is necessary that all outputs on one 5601MSC have the
same timing as those on the other. Identical timing for both 5601MSCs is assured by locking both to
the same frequency and phase source (i.e. GPS, or genlocking one 5601MSC to the other). Identical
phasing of the independent black outputs is assured by implementing the Syncro mode in the
5601MSCs. To use this mode, both 5601MSC communication ports are connected together using the
link cable supplied with the 5601ACO2. With both 5601MSCs operating in Syncro mode, timing
adjustments made to one 5601MSC will be automatically applied to both. The link cable is connected
permanently, so that any system re-timing will be applied to both 5601MSC units.
Features:
• Relay switches for all the system critical outputs from two 5601MSC units
• 6 video/sync outputs
• 8 SD/HD/3G SDI test signal outputs
• 2 Analog video test signal outputs
• 10MHz frequency reference
• Word Clock output
• Balanced and unbalanced DARS and 2 AES outputs
• Balanced analog audio output
• Linear time code outputs
• Automatic changeover is a voting system based on which source has the most valid signals and
that the good signals on the present master are also on the backup.
• Three switches behind the front panel select automatic, front panel or GPI activation of changeover
• 56 Front panel status LEDs show the health of each of the inputs
• 14 Front panel status LEDs show the operational modes of the changeover
• Hot swappable redundant power supply standard
