    I have 2 ERF modules that I want to drive at N4800.. Will be driving one with a 20M2 and the other with a 20x2. The documentation says that ERF will always be N9600 after a power-up cycle. Can I change this so they will always be N4800 after a power-up sequence? I've done searches on the FORUM...
