EmulatorII-list

So it doesn't appear that my new EII rev 0 has the rs422 daughter  
board installed. I wanted to confirm though because I don't really  
know what I'm looking for. Here are some pics I took of the back of  
the jack from a few different angles:

Second question, is there any chance something like this would work as  
a substitute?
