Ah okay I do see what you are saying. I googled null modem vs straight through and found this link here:
It does appear that according to the manual on page 103 that it is a straight through when compared to that link.
Now I am confused because the guy that showed me his Roomie setup said that he was pretty sure he used a null modem type, and that it even mentioned it in the manual. I just PM'ed him back to point out what I've found and seeing if maybe he was incorrect.
although now I'm even more confused lol, because the pinout on page 103 of the manual shows pins 7 and 8 being sent over, but the only one that shows 7 and 8 being used in the link I linked above is the null modem with handshaking.
After some MORE researching, on Roomie's website (what I plan on eventually using) it doesn't list the 8000 as a compatible device through serial, but I know for a fact that the 8000 does work since i've seen it work with Roomie and the serial adapter.
However it DOES list the 7000 on there, here:
And as you can see in the notes, it mentions "straight through" and you can see "null modem" in quite a few other places. I'm assuming if the straight through worked for the 7000, that it will work for the 8000. Additionally, the guy who showed me his Roomie and 8000 upgraded from a 7000. I asked him if he used the same serial cable for both and am waiting to hear back. So I'm thinking he just made a mistake intiially telling me he used a null modem type.Edited by purbeast - 12/28/12 at 11:05am
