The master-slave config types and port assignments have always been confusing.
The quick start guide lists a config where the master is port 1 and the slave
is port 7. I believe port 7 is called the sub-master in this config. With only
2 inverters it functions as the slave to the master in port 1. This config has
always worked for me.
Hope this is accurate info.

G'Day All,
So I started up a system recently with two Radian 8048A's. The master is
connected to port 1 and the slave connected to port 2 with the FlexNet at port
3. There are no OB charge controllers in the system. When the hub is polling
(led's scrolling) nothing shows up for the slave at port 2. It's like the slave
inverter doesn't exist. So I moved the slave and flexnet down to port 3 and 4.
No change in the polling. I swapped out comm (factory green) cables. Again no
change. Looking at the control board of the slave there is only one green led
on which is located at the upper right-hand side. Otherwise no led's are on. I
have 57v at the buss bar terminals of the inverter. Of course since there is no
polling at the hub there is no way to view port 2 to view the slave at the Mate.
Now the only thing that I didn't do was to try and use the manual on/off
switch-jumper to start the slave. But in the past regardless of the inverter
being on or off it would still show up on the hub. This is a new one and I'm
looking for some direction here.
Thanks,
Christopher-
