Input Signal Automatic Detection - IDK MSD-501 User Manual

7.2 Input Signal Automatic Detection

The MSD continuously monitors input signal. If input signal that have been input before, they are output with
the same size and quality of view used previously. If input signal is not matched with any signal that have
been input before, only settings of input timing is initialized and other settings are not changed. Adjust the size
and quality of view as necessary.
The MSD saves data of 50 input devices for each channel, and the data is used to check whether the input
signal have been input before or not. To save the data of the 51st device, the oldest data that have not been
input recently will be deleted, instead.
