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.

Protection for 8 channels of AES
Control channels
Protection on HD (1.5Gb/s) or SD (270Mb/s)
Protection for SMPTE ST 310
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 7700FC VistaLINK® Frame Controller module in slot 1 of the frame
