The ECO422D is a highly v ersatile sync changeover unit designed for
use in a serial SD/HD digital television environment. The ECO422D
will accom
AES/EBU digital audio, tri-level sync, and analog black-burst signals. This
flexibility makes the ECO 422D ideal for both the mixed-format and all-digital
television facility.

modate component or composite serial digital video signals,

The ECO422D provides eleven user-configured channels, each channel
consisting of primary and backup inputs, and an output.

Six channels can be set for high-definition serial digital video,
standard-definition serial digital video, AES/EBU digital audio, tri-level
sync, and PAL

Five channe
AES/EBU digital audio, tri-level sync, and PAL or NTSC analog black
burst

Channel configuration is by internal DIP switch. Signal amplitude fault
detection level follows the setting of the channel configuration switches.
Detection on individual channels may be disabled, giving the option of
disabling changes to the backup unit on failure of signals not critical to the
facility operation.

When operated in the switch-on-fault mode, the ECO422D will automatically
select the backup sync source should any of the primary inputs fail.
However, i
will not alternate between the two sources. If necessary, this function may
be overridden with the manual sync source selection. Manual so urce
selection also facilitates periodic testing of the changeover function.
Switching is by mechanical relay with all channels switched simultaneously.

The Electrical Fast Switch function, available with Opt. ELSW, improves the
changeover switching speed between inputs, and replaces the mechanical
relay on channels 4-6. Using this type of switch minimizes disturbance
when swit
channels 4-6 can only accept a black-burst or tri-level sync signal.

nel controls are provided for source selection, operating mode,

Front-pa
resetting the fault indicators, and for disabling the front-panel controls. LED
indicators are also provided . Indication of fault and unit on line is also
available through the remote connector.
