First time using the motolab cyclone flight controller, having trouble getting any inputs on Rx tab:

LemonRx dsmx sat wired correctly to the tiny holes labeled "sat rx". Satt is bound and has solid orange led. 
I have serialrx mode enabled, provider spek2048, and taer1234. Not sure which Rx port I should open, I assumed it's not uart1 or uart3 as they're the plastic connectors not used on the board. Tried uart2, no luck.

Thx in advance

Enable uart 2- the highest one at a time and after hitting serial rx you may have to go back to configuration and turn spek back on and maybe change to 2048 again.

Turn off msp on uart1 and open the serial on it. Save and reboot the go to configuration and select serial (spektrum). 1024 or 2048 not sure which you need. then save. Then bind you radio. You should have stick movement on the receiver page then. Until you get the correct port on the port page nothing else will work for your receiver.

Tried that, still no luck. The satt is definitely bound. Just read that sat Rx port is uart2 also. I swear I've tried every combination.
Tried uart2 again, no luck getting any response when moving sticks

rebind it doesn't matter if it seems bound. go to cli and type... set spektrum_sat_bind = 9 ....then reboot and it should be flashing the turn on your radio in bind. Things always dont go exactly the way a guide or manual says but the goal obviously ids to get it going and I've seen strange things that should not work end up working.

It sounds like your transmitter IS bound to the receiver. If you haven't done so, try making sure that the transmitter is turned on BEFORE applying ANY power to the FC (either with USB or flight Battery). My flip32s are finicky this way with USB. I have to turn ON the transmitter, THEN plug in the USB and open Cleanflight/Betaflight. Only then can I see movement in the receiver tab.
Good luck!
