MicroVideo SDI 2x1 Emergency Switch
The ESW201 is designed for applications requiring automatic emergency switching capability in the event of signal loss. The main program input in monitored and on loss of sync data, the output is switched to the secondary input.
If inputs are co-timed, switching in the VBI achieves a seamless changeover.
The automatic switching feature can overridden by the operator through external connection to the GPI, a simple switch is also provided on the front of the card to give users a quick method of switching between inputs. A tally output indicates when the switch has occurred.
The program path is maintained, even in the event of a power failure, through the inbuilt bypass relay.
