This setup is prepared because some FLARMs are set to different baud rates, so it’s
necessary also to set FlarmLed to same baud rate. Normally Flarm default baud rate is
19200bps, on that setting is also set FlarmLed display.
Master/Slave option is usable only if we have connected to flarm more than one Flarm led
display. In that case display can interfere each other. Only one can be set to Master, all
other must be set to slaves.
Last setting enables or disables PCAS warnings, which might be sometimes very annoying.
