2 pin connectors shorted with a jumper (where to measure the current consumption of the AS3930), a set of 4 pin connectors where to monitor the out coming signals of the AS3930, 1 button to program the AS3930, 3 red LEDs which show 3 different setups for the AS3930, and arrays of 5 green LEDs showing the RSSI of the received signal. -
Page 4: Overview Of The Tx Board
Application Note AS3930 – Description of Demosystem Regardless which mode is chosen, when the AS3930 wakes up the RSSI LEDs show the RSSI level, as it is read out from the R10<4:0> of the AS3930. the RSSI therefore will be shown as binary representation where BIT4 is the MSB and BIT0 the LSB. - Page 5 Application Note AS3930 – Description of Demosystem PREAMBLE PATTERN1 BUTTON PRESSING PATT2: pressing this button the board will send only one time the Pattern2 (C8)h –Manchester- following the preamble. When the Pattern2 is sent no more activity will be present on the antenna.
