7700ACO-HD

HD/SD-SDI, 8 Channel AES & RS-232/RS-422 Auto Change Over

  • VistaLINK® enabled

The Evertz 7700ACO-HD HD/SDI Auto Change Over is designed to provide a HD/SD SDI video, multi channel AES audio and RS-422/RS-232 change over in one device. The unit can be controlled via GPI, remotely via VistaLINK® PRO or set in autochangeover mode. It is an all-in-one ACO package aimed towards protecting a complete channel. (ie. protecting the video, 8 channels of discrete AES and associated control channel (RS-232 or RS-422)). The unit features latching relays that maintain state through loss of power.

Features
  • Auto detection of signal standard
  • Four modes of operation:
    • Auto changeover - two standalone auto changeovers
    • Manual DIP switch control - two independently controlled 2x1 switchers
    • GPI Control - two independently GPI controlled 2x1 switchers
    • Tally output provided
  • Protection for 8 channels of AES
  • Control channels
  • Protection on HD (1.5Gb/s) or SD (270Mb/s)
  • Changeover conditions are based on signal presence of:
    • HD/SDI (TRS timing, CRC and EDH)
    • DVB-ASI (SMPTE sync word)
    • Sync (H timing)
    • AES (sync word)
  • VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
