[RC232] What type of modulation type in the RC1190-RC232? RC1190-RC232 use GFSK modulation. Last Update: August 8, 2017 December 13, 2016 2410 RC232 Q&A Related Knowledge Base Posts -[RC232] For a new project I would like to obtain an ultra long range, better than the RC1780HP[RC232] I’ve noticed the label FCC pending on the RC1190HP. Could you please confirm is FCC approved?[RC232] 1. How does the RC1180-RC232 react as the supply voltage reduces below the minimum operating voltage and below – the system is powered by a Solar cell secondary cell to hold charge short to medium term. It is possible the secondary cell will start to discharge beyond the requirement for operation – does the module need to be unpowered to protect it from brown-out situations.
