Rs232 To Hdmi Cable: Types, Key Features, and How It Supports Industrial Performance
March 20, 2026 - The RS232 to HDMI cable is not a simple passive cable but rather a specialized signal converter that enables communication between legacy serial devices using the RS-232 protocol and modern digital displays equipped with HDMI inputs.
Connecting to an HDMI matrix using RS232 USB to TTL cable
Looking at the specs for that interface it appears that white is the rx of the adaptor which should connect to the tx of matrix, and green is the tx of the adaptor, which should go to the rx of the matrix. So, try swapping rx and tx and see if that gets you any closer More on reddit.com

RS232 to HDMI Converter Guide: How to Choose Right
April 30, 2026 - What’s marketed as an “RS232 to HDMI converter” is almost always either (a) a HDMI extender with built-in RS232 control passthrough, or (b) a misnamed DB9-to-HDMI adapter cable that physically connects but cannot translate signals.

r/CommercialAV on Reddit: Connecting to an HDMI matrix using RS232 USB to TTL cable
January 7, 2024 -
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
