I needed to control a 4X4 Matrix switcher for an installation from Node-RED so that I can bring the control of all hardware into one interface.
IR was an option, as inspired by this thread
However I found a simple (very simple) 4X4 4K HDMI switcher that has an RS232 port.
(it also comes with "rack ears" which is a bonus)
https://cpc.farnell.com/pro-signal/psg3450/4x4-4kx2k-60hz-matrix-switch/dp/AV29284
The commands were pretty simple, so I embarked on building a Flow
The RS232 <> USB dongle I have works with my Windows machine, but not the Linux machine that I want to deploy on site, so I'll have to find another dongle.
However, I do have a couple of LAN <> RS232 adapters, the flow I have created has provision for both solutions.
LAN Adapter is a USR-TCP232-306
With this flow I can ==
- Control each output independently.
- Select one input for ALL outputs
- Group outputs (defined in the admin, not on the fly)
