The interface from the FA2 is USB, so there is no need (and no way) to go through a DB9. I recommend using an adapter to go from your tablet (typically micro-USB or USB-C) to a USB-A socket, then use a standard USB-A male to USB-B male cable going to the FA2.
One issue: once the tablet is connected to the FA2, there will be no way to charge the tablet, so start with a fresh battery... The app keeps the screen activated as long as the battery is >50%. After that, Android will put the app to sleep and recording will stop and the data that is not saved will be lost. There are a number of ways to deal with that, I am waiting to see actual use cases to come up with the best way. The battery life limitation is clearly an issue. You can buy cables that have a charging port but they only power the target (the FA2 in this case), not the tablet. I believe that you cannot charge the battery when the USB port is used as a master because as a master it is intended to deliver power, not receive it.
