DR-TRC103-DK User’s Guide (2015/04/17) Page 2 of 22 www.murata.com DR-TRC103 development kits are designed to facilitate the configuration of all TRC103 transmitter, receiver and interface functions, and to support application firmware and system development. The development kits can be controlled using the RFIC Design Assistant utility software. Two-way communication link testing is also supported by the data terminal program built into the RFIC Design Assistant utility. In addition, a standalone range test function is included in the radio board firmware to allow roaming range tests. Figure 1 shows a development kit interface board with a radio board installed. Figure 1 - DR-TRC103-DK Radio and Interface Board Set The antennas included in each development kit match the operating frequency of the kit, and may be a different length than the antenna shown above. Antennas should always be installed before turning on a radio board. ©2015 by Murata Electronics N.A., Inc. DR-TRC103-DK User’s Guide (2015/04/17) Page 3 of 22 www.murata.com Figure 2 - DR-TRC103-DK Interface Board Connectors and Controls Figure 2 shows the locations of the interface board DC power connectors, user controls and LED indicators. Normally an interface board is powered from one of the 4.5 volt universal wall-plug power supplies provided in the development kit, as shown in the left panel of Figure 3. For roaming range testing and field testing, the interface board can be powered from a 9 volt battery as shown in the right panel of Figure 3. Note - do not install a 9 volt battery while the interface board is connected to the wall-plug power supply. Use only one power source at a time. Power input pins are also provided for connection to a regulated 4.5 to 12 volt lab supply. When connecting to these pins, take care with the polarity. The pin closest to the power connector is the positive input. Figure 3 - Power Options ©2015 by Murata Electronics N.A., Inc. DR-TRC103-DK User’s Guide (2015/04/17) Page 4 of 22 www.murata.com The power switch shown in Figure 2 connects the output of the 3 volt regulator on the interface board to the POWER ON LED, the serial communication interface circuitry and the radio board. Note that there is a small current draw from the regulator when the power switch is in the off position, and this will eventually discharge a 9 volt battery if it is left installed. The radio RESET button on the interface module allows the user to reset the radio board to a know state from any mode the radio board is in. Figure 4 - DR-TRC103-DK Interface Board Serial Connectors Figure 4 shows the serial communication connectors on the interface board. The kit includes two USB 2.0 A/B cables for connection to a PC. When a USB cable is plugged into an interface board, it automatically disables the RS232 interface circuitry. Note that the interface board is not designed to be powered from the USB interface, so DC power must be supplied separately as discussed above. The kit CD includes the PC drivers needed to make the interface board USB connection appear as a virtual COM port. Refer to the USB Virtual COM Ports section of the RFIC Design Assistant User’s Guide on the CD for driver installation details. To configure the interface board for RS232 operation, remove the serial jumpers shown in Figure 4. Use a 9-pin “external modem cable” (straight through, not null modem) to connect the interface board to the PC. The left panel in Figure 5 shows USB operation, the right panel shows RS232 operation. Note the serial jumpers have been removed for RS232 operation. ©2015 by Murata Electronics N.A., Inc. DR-TRC103-DK User’s Guide (2015/04/17) Page 5 of 22 www.murata.com Figure 5 - USB and RS232 Serial Connection Options Initial Kit Testing Using the Range Test Function 1. Install the antennas and then the 9 volt batteries in both board sets. No PC connection is required for the range test function. 2. Turn on the board sets by sliding the Power switch on the interface board to the ON position. All LED’s on the radio board will flash and the MODE LED will be green. 3. See Figure 6 below. 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 radios are receiving good packets, then the green Good Packet LEDs will be flashing alternately on each board (plus various yellow LEDs). Figure 10 details the locations of the 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. Frequency Hopping Spread Spectrum Range Test Function The 902-928 MHz kit can also be range tested in frequency hopping spread spectrum (FHSS) mode. On each board, press the MODE button four times. After the forth press, the MODE LED will illuminate green-yellow. Then on one board, briefly press and release the RANGE button. The RANGE LED will illuminate continuously. This is the “receiving” board. On the other board, press and hold the RANGE button until the LED’s begin flashing. This board is the “transmitting” board. ©2015 by Murata Electronics N.A., Inc. DR-TRC103-DK User’s Guide (2015/04/17) Page 6 of 22 www.murata.com Figure 6 - Initial Testing Using Range Test Function Kit Testing using the RFIC Design Assistant 1. Install the RFIC Design Assistant utility program from the kit CD. If you are using the USB interface, install the virtual COM port drivers. Refer to the USB Virtual COM Ports section of the RFIC Design Assistant User’s Guide on the CD for driver installation details. 2. If installed, remove the 9 volt batteries from the board sets. Install the antennas as needed and then connect a 4.5 volt wall-plug power supply to each board set. 3. Connect one of the board sets to the PC. Turn on the board set by sliding the Power switch on the interface board to the ON position. All LED’s on the radio board will flash and the MODE LED will be green. 4. Start the RFIC Design Assistant utility program as shown in Figure 7. Select the COM port or virtual COM port assigned to the board set from the drop-down menu at the top of the utility program screen. The COM port can be determined from Windows® as follows: Start > Settings > Control Panel > System > Hardware > Device Manager > Ports (COM & LPT). 5. Select the TRC103 from the TRC drop-down menu as shown in Figure 8. This will launch the TRC103 multi-tab dialog window as shown in Figure 9. 6. Select the Main Menu tab and click on the Read Configuration button. A hex dump of the current TRC103 configuration parameters should appear in the text box above the button as shown in Figure 9. This confirms the development board set is communicating with the utility program. Test the other development kit board set in the same manner. The development kit is now ready to use. ©2015 by Murata Electronics N.A., Inc.

DR-TRC103-DK User’s Guide (2015/04/17) Page 9 of 22 www.murata.com When a DR-TRC103 radio board is initially power on, it is configured as follows: Operating Frequency: DR-TRC103-868-EV 868.35 MHz DR-TRC103-915-EV 916.50 MHz DR-TRC103-950-EV 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. ©2015 by Murata Electronics N.A., Inc. DR-TRC103-DK User’s Guide (2015/04/17) Page 10 of 22 www.murata.com Figure 11 - DR-TRC103 Radio Board TX Power Adjustment Two AA battery packs are supplied in the development kit to power the radio boards when they are removed from the interface boards, as shown in Figure 12. Alternately, a regulated power supply in the range of 2.7 to 3.6 volts 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. 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. The AA battery packs should only be used to power standalone radio boards. They do not provide enough voltage to reliably power the interface boards. Do not attempt to power a radio board through its battery connector when it is plugged into an interface board.

DR-TRC103-DK User’s Guide (2015/04/17) Page 14 of 22 www.murata.com The firmware includes several command formats that are used by the RFIC Design Assistant utility program to read and write parameters to the TRC103 configuration registers and to send and receive terminal mode messages. Table 6 summarizes several commands that are useful for proof-of-concept testing. Command Format Write Register Wrrdd or wrrdd Terminal Mode Send Terminal Mode Receive Example Write register rr with data dd, where rr and dd are two character hex values. For example, write 0x80 to register 0x01 is formatted as W0108. 02msg03 The DR-TRC103 radio board must be in terminal mode, as discussed in Table 5 above. The user’s message, up to 63 bytes, must be preceded with an ASCII 0x02 start-of-text character, and followed by an ASCII 0x03 end-of-text character. For example, the string of hex characters to send Hello in ASCII is: 0248656C6C6F03 02msg030D0A When the example string above is output by the receiving node, an ASCII carriage return - line feed is added as follows: 0248656C6C6F030D0A Table 6 - DR-TRC103 Firmware Serial Commands Figure 16 - DR-TRC103/105 Interface Board Connector for Firmware Development Support Custom Firmware Development Support The 10-pin programming header on the interface board is compatible with the Silicon Labs development tools for the C8051F310 microcontroller.
