okay, I have something called OVL420, and OVL400. so I changed the ssc card, and put the same daughter board, and the dongle, change the SID to be as the old one, and everything is working now, I want to buy another one and prepare it to be as a spare one? but I don't know If I buy the NTDK20JA as card, does it need a software, and other things such as passwords, or it all will be stored at the daughter board NTSK40AC,
