Hi,
I'm trying to connect to the HDMI matrix (AV Access Professional 4x2 4K@60Hz HDMI 2.0 Matrix Switch) using Prolific PL2303TA cable. Latest cable driver is installed correctly and is recognized by windows. I connect TTL pins directly into the matrix (it has RS232 terminal block): Green - Tx, White - Rx, Black - G.
I've tried Putty and Serial Debug Assistant, port is opened successfully, but no response is received. RS232 settings are correct as per official documentation https://www.avaccess.com/wp-content/uploads/2023/12/API-Command-Set_-4KMX42-H2A-V1.0.1.pdf
Any advice is very welcome
Upd: problemo solved, connecting a TTL into RS232 is no go
Idk if this is the right sub or even the right way to ask this ; My pc has no HDMI port but has this, and I've heard it could replace HDMI with an adapter. Is it true? If it is well I don't know what adapter to search for. Google Lens didn't really help. Anyone knows??
