I programmed three NEW drivers for VControl 4. If you know the Device, 220pro is a fiber optic HDMi transmitter with 2x inputs and 3x outputs on the receiver side. The device communication protocol is LW3.
I wrote two versions. One is divided for TX and RX and has a Live Update function. This means, the device is constantly requested by VControl to get Port and Device Information. You can write a HTML Page and monitor all your fiber optic device incl. link speed (fiber quality) and if signal is availible on the port and if a cable is connected.
If you don’t want traffic on the network between the Devices, you can also use the reduced TX/RX driver, which can only sends commands and don’t request the Device.
