 ### Configuring Serial2 on ESP32 non-PWM receivers
 
-Some non-PWM receivers like the RadioMaster RP4TD have spare pins exposed. The pins are configured for Serial2 by default. 
+Some non-PWM receivers like the RadioMaster RP4TD have spare pins exposed. The pins are configured for Serial2 by default. For Serial2 protocol selection use the ELRS LUA script and follow the Protocol 2 section of [Other Devices](https://www.expresslrs.org/quick-start/transmitters/lua-howto/?h=2+protocol#other-devices).

 ## SUMD Notes
 
 SUMD is the Graupner HoTT bus protocol used to transmit multiple channel data over a single serial line. It transports up to 16 full res channels at a rate of 100Hz and is mainly used to provide digital channel data to Flybarless Control Systems for helicopters and older Flight Controllers.
