Product Overview
Introducing the 5700ACO Automatic Changeovers – the ultimate solution for TV station video and time synchronization. Designed for two 5700MSC Master Clock/Sync Generators, it ensures reliability and minimal disruption with mechanical relays, even during power failures. Featuring 2RU ACO, dual power supplies, and enhanced security with switches for manual and automatic modes. LEDs provide status info, while VistaLINK® allows customizable autochangeover features. Simplified installation with GPI/GPO connections. Experience unparalleled security and efficiency with the 5700ACO Automatic Changeovers.
Evertz 5700ACO Features:
- Three protected switches select automatic, front panel or GPI activation of changeover
- Front panel status LEDs show the health of each of the inputs
- Front panel status LEDs show the operational modes of the changeover
- Redundant power supply standard
- Push button to show cause of last changeover
- Dual hot–swappable power supplied and fans
- Hot–swappable main board
- GPIO input/outputs
- Automatic changeover is a voting system based on which source has the most valid signals and that the valid signals on the present master are also on the backup
- VistaLINK® control for device configuration and status monitoring
- Six video/sync or other coaxial signals
- 10MHz frequency reference
- Word clock output
- DARS and 3 AES
- Two Longitudinal (LTC/EBU) timecode outputs
- Four SD/HD/3G outputs
