interfacing microcontrollers to Blackmagic MicroConverters

PostSun Dec 05, 2021 7:44 am

I have designed a controller that can allow network control of any Blackmagic converter; and its free!!!

http://www.bazcontrollers.com/mv4%20mod.pdf
Here is a quick overview:
How to interface a microcontroller to Blackmagic MicroConverters.
The microController is an Arduino but can be any microcontroller that has an ethernet port and 8 bi-directional control pins. The only controls available are those that are available as dip switches on the Blackmagic device.
As an example I am using a Blackmagic Multiviewer 4HD to replace a Teranex Multiviewer 4 that I was using as a CCU monitor with my 4 x CCU controller. My 4 x CCU controller uses the Blackmagic protocol published in their users manual.
The modification requires all dip switches to be set in the OFF position but if set to on will override the microcontroller. The Blackmagic Multiviewer 4HD will still perform normally both when connected to the Arduino and disconnected.
Please note this modification will void your manufacturer’s warranty so I am doing it as my warranty has expired. Also note I take no responsibility if anything goes wrong.
I have used both an Arduino UNO with W5100 ethernet shield and an Arduino Nano with a Nano V3 ethernet shield. It uses a 9 wire ribbon cable wired to a 9 pin ‘D’ connector
