RS232 with matrix switcher

[Gast]

Hello,

I hope someone does understand what i want and can help me with it.

I have a rs232 extension and i want to control a HDMI matrix controller with it. I have the codes and the information from the manufacturer but i it doesn't work. So what am i doing wrong or is it not possible to control the switch with loxone.
I have included the manual (codes) i only need the possibility to switch all the other functions is not important for me.

So i like to know if i am doing something wrong or that it is not possible?

Regards

Hello,

I assume that you have properly set the RS232 according to the manual
Baudrate : 115200
Data width : 8bit
Parity : none
Stop : 2 bits

By comparing example in the manual and your screnshot I see different.

By manual : A5 5B 02 03 02 00 01 00 00 00 00 00 F8
Your : A5 5B 02 00 00 03 01 00 03 00 00 00 00 00 F8

It is problem. That must be 13 bytes. You have 15 bytes. And don't forget that you must by another hexa string calculated checksum.

Have a nice day.

What is the model and the producer of the matrix switch? I'm searching for one that works with loxone. Thanks!
