I have a project where I need to be able to programmatically switch between 2 HDMI inputs. I need a "turn-key" solution, not something where I would need to hack an HDMI switch since I am going to need to deploy a large amount of of these devices.
After some research, I found a reasonably priced HDMI switch
that can be controlled by an RS232 input.
The GPIO pins are going to be used for other functionality, so I would like to look in to the USB <-> RS232 converter. I have seen these talked about on these forums.
What would be a good RS232 to USB cable/converter I could use to talk to this device? Is it even possible? I need to be able to programmatically control this HDMI switch, not just toggle, but specifically tell it "use HDMI1 or use HDMI2".
Thank you for any insight you can provide.
