Brain 2 mini - SAT1 not working but in SAT2 work perfectly
Hi, I have a Brain2 mini purchase 3 days ago and they update to the last firmware when I log into the software, I am using Spectrum NX8 and DMXS satellite. when binding the receiver in SAT1 the FBL never initialize the receiver or even detected, when I switch and do the same process in SAT2 it bind and work perfectly, and is fully functional and I was able to complete the configuration in SAT2. after that I decided to switch to SAT1 again and the FBL never initialize or power the receiver, so move back to SAT2 and the FBL power the receiver and fully functional, I was thinking that maybe the mini brain need to have the two receiver connected in order to activate the ports, but I don't think is normal, I really like how is working in SAT2 so I am thinking to keep it or just replaced because is only 3 days old and I just fly two time for testing and it was amazing. but thinking in the future to add a second receiver will be then an issue.
The signal from the Spektrum satellites is connected directly to the processor of the flight control unit from which it is directly controlled. Operation is ensured by only two soldering, that of the connector and that of the processor pin. There are no series resistors or other components connected to the signal to make it work properly and the connectors are tested in production. For this reason it is highly unlikely that a satellite will not work because of the control unit, in fact it is more likely that this has never happened until now.
Instead, there are much more frequent cases where Spektrum cables do not work. They are in fact produced by Spektrum using very thin copper wires which break easily or are easily pulled out by crimping the contacts. This frequently occurs if the wire connectors are pulled out by the wires.
If you are certain that the used cable is working properly and that the connector pins have not been deformed, bent, twisted, mis-inserting the connector, then ask the store that sold it to you and knows if it is still under warranty to replace the control unit.
