The RS232 IN serial port of the HDMI matrix with 16 inputs and 16 outputs is mainly used to control the switching of the matrix. At the same time, it can also be connected to the central control system through the middle Control system to control the matrix. RS323 OUT male socket is actually the loop-out of RS232 IN, which can control other HDMI matrix. The CONTROL OTHER DEVICES serial port is also called "network central control" serial port.
