VAG-COM 311.2 Kit

Hello, I have a question.
I'm in the process of building this diagnostic board.
I've managed to find everything in my company's inventory except for the optocouplers.
Can anyone tell me if I can find something like this at Segor?
I can't find anything under the model number.
It would be best if someone who has already built it could send me their shopping list .
I happened to come across version 0.81 of the VAG-COM software, and it works perfectly. Is there any difference between the English and German versions, other than the language?

Hello,

My apologies, I could have found this myself using the search function, but thank you anyway.
