When a DR-TRC103 radio board is initially power on, it is configured as follows:
Operating Frequency:
DR-TRC103-868-EV
DR-TRC103-915-EV
DR-TRC103-950-EV
868.35 MHz
916.50 MHz
950.00 MHz
Power: +10 dBm
Frequency Deviation: ±50 kHz
Data Rate: 25 kb/s
Receiver Baseband Bandwidth: 100 kHz
The radio board is also initially configured in Receive Continuous Mode (see the
TRC103 datasheet for an explanation of continuous mode, buffered data mode, packet
data mode, etc.). In receive continuous mode, the MODE LED will be green. Receive
continuous mode allows the user to connect a modulated signal from a signal generator
source onto the board through a short, coaxial cable and verify the demodulated signal
with an oscilloscope through the DAT pin.
Briefly pressing the MODE button once configures the board into Transmit Continuous
Mode . The Mode LED will change color from green to yellow. This mode turns on the
transmitter. The frequency and output power may be verified on a spectrum analyzer. A
square-wave modulating signal may be applied to the DAT pin and modulation
observed on the spectrum analyzer.
Briefly pressing the MODE button again configures the board into Sleep Mode . The
Mode LED will turn off. By connecting an ammeter across the terminals of J1, with the
jumper removed, the user can verify the very low sleep current of the TRC103 device.
As shown in Figure 11, potentiometer R7 can be used to adjust the transmit power
level. To increase the output power, rotate the potentiometer screw clockwise. To
decrease the power, rotate the potentiometer screw counterclockwise. The transmit
power is divided into 8 levels. Adjusting R7 adjusts the voltage level to the A-to-D
converter (ADC) in the host microcontroller. The microcontroller periodically samples R7
for a change, and updates the transmit power register when it detects a change in
voltage level. Each time the microprocessor updates the transmit power register the SPI
LED D2 will flash indicating an SPI write.
