ATEM Mini TCP/UDP protocol

PostTue Oct 13, 2020 8:31 pm


I would like to control my ATEM Mini with TCP. If I have fully understood, HyperdDeck protocol is not working for ATEM Mini.

I have make some network analysis and discover that 2 ports are open on the ATEM Mini.
TCP 9977 :
telnet 9977
Connected to
Escape character is '^]'.
Version: 1.0

Model name: ATEM Mini
Unique ID: 2f3a0ea8c7c14fb48f3XXXXXXX
Label: ATEM Mini
Host name: ATEM-AVA-7c2e0dXXXXXX


And port 9910 UDP.

TCP9977 is used by ATEM Setup, and UDP9910 by ATEM Software.

Does anyone knows which is the protocol used for 9910 ?

My goal is to send datagram to change preview, source, etc ...

Many thanks,

The raw control protocol is not available, the only supported method of doing this is through the Atem SDK. However there are many open source efforts to document and implement the protocol, such as the work by Skaarhoj - - (although their open source stuff doesn't cover the version 8 software used by the Atem Mini). It's not an easy protocol to implement and relies on a load of binary data and specific timing.
