AS3900 - Demo Board Manual
27MHz Low Power FSK Transceiver
Operational sequence
This demo board comes with one antenna, one 3V battery and one USB-cable.
Prepare the Hardware

Drive the IC on the demo board only with the recommended settings and values as described in the
datasheet. If not present get the datasheet for the AS3900 from www.austriamicrtosystem.com .
First connect the power supply via connector “G” to a powered USB port or insert the provided 3V
battery. Power on the Demoboard by turning the switch “F” to USB or BATT. The Master is
recommended to be supplied from USB. The Client is supplied from the 3V battery. To power down the
system turn the switch “F” into its middle position (OFF).
Select one Demoboard as Master and at lease one Demoboard as Client at Switch “D” . Make sure not
to have more than one Master.
Select for each Client a unique ID via the Dip Switches “E” . Make sure not to have Clients with the
same ID.
PAIR the Clients to the Master

Press the “PAIR” Button “C” at all Clients. The “PAIR” Button is blinking red.
Press the “PAIR” Button “C” at the Master. The Master starts the communication and the Clients send
their IDs. If the Master gets valid IDs the PAIR LED switch from blinking red to blinking green. This
mean, that the Master has recognized at least one Client for the network. After a handshake the Clients
start to blink green as well.
If not all Clients are paired at the first time, press the “PAIR” button at the master again, until all Clients
are blinking green.
The GUI at the Master shows all valid Clients with their appropriate address. (Dip Switch + 1)
WAKEUP the Clients to start the communication
After the clients are successfully paired, they are automatically switched into a Sleep Mode. In order to start the
data communication, the Clients need to be woken up:

Press the “WAKEUP” Button “B” at all Clients. The “WAKEUP” Button is blinking red. As soon as the
communication is running the WAKEUP Button is blinking green.
Press the “WAKEUP” Button “B” at the Master. The Master starts again the communication and the
Clients begin to send data. As soon as the Master receives valid data, the WAKEUP Button at the
Master is blinking green as well. Transmitted, received and lost packages are indicated via LEDs
“ TRANS-PACK” , “RCV-PACK” and “LOST-PACK” .
The brightness sensor can be seen on the GUI (Master) and actual data can be changed at the Clients
by shading the sensor.
Once the connection to one Client is lost, the appropriate Client stops blinking “ TRANS-PACK” and
“RCV-PACK” . If the Client is again very close to the Master the connection is re-established
automatically. “ TRANS-PACK” and “RCV-PACK” starts to blink again.
Note: Pressing the WAKEUP Button “B” at the Master, starts and stops the communication.
