DR-TRC105-DK User's Guide11/23/15 1 of 16 www.murata.com Introduction The DR-TRC105 series evaluation kits include the radio boards, antennas and battery packs used in the DR-TRC105 series development kits. The evaluation kits can be used for initial evaluation of TRC105 radio technology and to prototype applications that will use the TRC105 RFIC. This user guide covers the following evaluation kits: Evaluation Kit Part Number DR-TRC105-304-EV DR-TRC105-315-EV DR-TRC105-345-EV DR-TRC105-372-EV DR-TRC105-390-EV DR-TRC105-403-EV DR-TRC105-434-EV DR-TRC105-450-EV Operating Frequency Range 303.325 - 307.300 MHz 310.000 - 319.500 MHz 342.000 - 348.000 MHz 365.000 - 380.00 MHz 382.000 - 398.000 MHz 402.000 - 407.300 MHz 418.000 - 434.790 MHz 447.000 - 451.000 MHz Table 1 - Evaluation Kit Part Numbers Each DR-TRC105 evaluation kit contains the following items: * * * * 2 DR-TRC105 Evaluation Boards 2 Dipole Antennas 2 AA Battery Packs 4 AA Batteries The DR-TRC105 radio board connectors and user controls are shown in Figure 1.

Alternately, a regulated power supply in the range of 2.7 to 3.6 volts (c)2010-2015 by Murata Electronics N.A., Inc. DR-TRC105-DK User's Guide11/23/15 3 of 16 www.murata.com can be used to power the radio boards. Note - there are no voltage regulators on the radio boards. Applying a voltage outside the specified power supply range can damage the boards. Do not attempt to power a radio board directly through its battery connector using one of the 4.5 volt wall-plug power supplies provided in a DR-TRC105-DK series development kit. The 4.5 volt power supplies are used to power the development kit interface boards, which in turn provide regulated 3 volts to the radio boards. See the DR-TRC105-DK User's Guide for additional details. Figure 3 - Powering the Radio Board from a Battery Pack Initial Testing Using the Range Test Function 1. Install batteries in both battery cases and plug the cases into the radio boards. 2. Turn on the boards by sliding the switch as indicated in Figure 1. All LED's will flash and the MODE LED will be green. 3. On one board, briefly press and release the RANGE button. The RANGE LED will illuminate continuously. This is the "receiving" board. 4. On the other board, press and hold the RANGE button until the LED's begin flashing. This board is the "transmitting" board. 5. If the radio boards are receiving good packets then the green Good Packet LEDs will be flashing alternately on each board (plus various yellow LEDs). 6. To verify that the radio boards are operating properly, disable the "receiving" board by pressing and releasing the RANGE button twice. The RANGE LED will turn off. On the transmitting board, you should observe the red Packet Error LED flashing. This indicates that the transmitter sent a packet but did not receive an acknowledgment back from the "receiving" radio board. (c)2010-2015 by Murata Electronics N.A., Inc. DR-TRC105-DK User's Guide11/23/15 4 of 16 www.murata.com Radio Board Configuration When a DR-TRC105 radio board is initially power on, it is configured as follows: Operating Frequency: DR-TRC105-304-EV DR-TRC105-315-EV DR-TRC105-345-EV DR-TRC105-372-EV DR-TRC105-390-EV DR-TRC105-403-EV DR-TRC105-434-EV DR-TRC105-450-EV 303.825 MHz 315.000 MHz 345.000 MHz 372.250 MHz 390.000 MHz 403.500 MHz 433.920 MHz 450.000 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 TRC105 datasheet for an explanation of continuous data 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 an RF signal generator onto the board through a short coaxial cable and verify the demodulated signal with an oscilloscope at 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 with a spectrum analyzer. A square-wave modulating signal may be applied to the DAT pin and the spectrum observed on a 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 TRC105 device. As shown in Figure 4, 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 will flash indicating an SPI write. (c)2010-2015 by Murata Electronics N.A., Inc.

Figure 5 can be used with the schematics in the last section of this manual to design an application interface for the radio boards. Note that all signal levels into and out of this connector are nominally 3 V logic level. Attempting to use RS232 signal levels to directly interface the radio board can damage it.
