what yo show us are settings for the physical layer.
what you really need is the protocol.
if you look at page 7-3 from this manualhttp://www.finishlynx.com/download/fini ... sion_4.pdf
you see that the software support quite a lot off protocols.
probally you have to search for these protocols on the scoreboard manufacturer side.
there is also a database function in the software chapter 8 in the manual.
i have the feel that using this functionality is more 2016 then using a serial protocol.
i guess the developer is friendly enough to help you out in this.
