The SCO-1421 is a 2x1 intelligent ASI change-over with built-in MPEG-TS probing. Changeovers are performed electronically by the SCO-1421’s internal router. In the event of a power failure, the signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output.

Input selection can be performed automatically or manually. In automatic mode, the card will perform smart input selection based on rules related to signal quality. In manual input selection mode, channel selection can be made from the Densité controller, the iControl software, or simply by using a GPI. A GPI can be connected to an automation system or any simple GPI control panel. The GPI outputs give status of the selected source, allowing tallies to be triggered.

MPEG-TS signal probing monitors PID presence of up to 12 services per input simultaneously. In the event of a loss of data on any service PID, the SCO can be configured to automatically switch to the other input provided it is error-free
