HD3SS215: recognizing the presence of the source

Lenio Cacula

Part Number: HD3SS215

I understand the HPD signal goes from sink to source, indicating the monitor is ready to receive data. In case I have two sources (cameras) and one sink (a computer), is there similar signal that the system can detect the presence of the source?

Thank you!

HI,

The HDMI allows the source to provide a +5V power to the cable and the sink, and you can use the +5V to indicate the presence of the source.

Thanks

Thank you - I assume you are referring to pin 18 of the HDMI cable?
