DC 5V Figure 1.3 4-AA Battery Pack 1.4 USB-RS232 Serial Cable (May Not Be Included) If you have a RS232 serial-serial cable and your notebook/PC has a RS232 serial port, you do not need a USB-RS232 serial cable. The evaluation kit does not include a USB-RS232 serial cable that would be required to configure the evaluation boards with the desired CU or MU settings in GUI. You have to provide this cable as shown in figure 1.4. Figure 1.4 USB-RS232 Serial Cable 1.5 Stereo-RCA Cable (May Not Be Included) The evaluation kit does not include a stereo-RCA cable, as shown in figure 1.5, that would be required to connect between stereo jack of MP3 Player, Notebook/PC to the Left + Right RCA jacks of the evaluation boards, or viceversa. Left Right Stereo Figure 1.5 Stereo-RCA Cable 1.6 Graphical User Interface GUI (delivered by e-mail) The evaluation kit also includes a graphical user interface program called GUI that is delivered to you via e-mail with the latest version from our WSS offices, shown in figure 1.6. GUI allows you to customize application settings on the CU and MU(s) in order to evaluate our solution for the high quality audio and wireless robustness of the 3141 130 0034.1 module. Figure 1.6 Graphical User Interface GUI 2. Easy steps to setup the evaluation boards One evaluation board has already been configured as the Central Unit (CU) and the other evaluation board as the Mobile Unit (MU) as shown in figure 2a, which is a 2 Speaker NACK configuration. RCA Connector (Left A and Right A) 5V DC Source CU 5V DC Source MU Wireless Distance Headphone Figure 2a CU and MU in a 2 Speaker NACK Configuration Step 1: Check that CU is configured correctly (see 2.1 CU Custom Settings). Check that MU is configured correctly (see 2.2 MU Custom Settings). Step 2: Connect 5V DC source to the CU and MU. Switch on the power. NB: Maximum rating of 7V DC is allowed. 4-AA battery pack may be used. Step 3: Check that Power On LED lights up. Step 4: Check that only AT128 LED lights up. Step 5: Check that Link LED lights up at the CU. NB: This is an audio link indication, not RF. If no audio source is provided to the CU, the Link LED will turn off after 5 seconds. Step 6: Check that either RF1, RF2 or RF3 lights up at the CU and MU. If they are alternately blinking, wait until only one of them lights up. MU will wait until the CU to fix a RF channel before it can wirelessly linked to the CU. Step 7: Use the Stereo-RCA cable that has a 3.5mm stereo plug on one end, whereas the Left + Right RCA plugs on the other end, shown in figure 2b and figure 1.5. RCA Plugs Left (White) Stereo plug Right (Red) Figure 2b Stereo-RCA Cable Step 8: Connect the stereo plug of the Stereo-RCA cable to an audio source. (Example of audio source: MP3 Player, Notebook/PC or DVD/CD Player) Step 9: Connect the RCA plugs of the Stereo-RCA cable to the RCA jacks of the CU. Left (White) plug to Left A jack. Right (Red) plug to Right A jack. Step 10: Check that the Link LEDs light up at the CU and MU. If no audio source is provided to the CU, the Link LEDs will turn off after 5 seconds. Step 11: Connect a stereo headphone or speaker to the MU headphone 3.5mm stereo jack. Step 12: Play music at the audio source and listen from the headphone or speaker. Step 13: Press Volume Up/Down buttons to adjust the audio volume. The CU provides the master volume control to all the MUs. The MU provides the local or slave volume control only to the MU. The AT8 LED will light up at CU and MU when Volume Up/Down button is pressed. Step 14: Move around to experience the wireless capability and robustness of our product. Notes 1: If you hear fuzzy noises or breaks before you walk more than 5 metres between the CU and MU, this indicates that either your 4-AA battery pack is running low. If the Power On LED looks dim or fading, please replace DC source. 2: If you hear distortion and the Link LED is off, the MU fails to link wirelessly to the CU. This indicates that either the range is exceeded or there is a huge interference. You can move around or closer to the CU. The MU will automatically re-link to the CU. 3: If all the 3 RF LEDs blinks together at every 3 seconds, this indicates that the FFC cable connection is loose. 2.1 CU Custom Settings The Central Unit (CU) is configured to accept audio input, from either S/PDIF or L+R stereo channel A and B. To accept audio input from S/PDIF, configure S/PDIF In/Out jumper and S/PDIF I2S jumper as shown. I2S S/PDIF IN OUT S/PDIF To accept audio input from stereo channel A and B, configure S/PDIF I2S jumper, Left A jumper, Right A jumper, Left B jumper, and Right B jumper as shown. I2S Left A IN Right A OUT IN Left B OUT Right B S/PDIF IN OUT IN OUT 10 2.2 MU Custom Settings The Mobile Unit (MU) is configured to produce audio output, either to S/PDIF or two L+R stereo channel A and B or headphone mini-jack. To produce audio output to S/PDIF, configure S/PDIF In/Out jumper and S/PDIF I2S jumper as shown. I2S S/PDIF IN OUT S/PDIF To produce audio output to stereo channel A and B, configure S/PDIF I2S jumper, Left A jumper, Right A jumper, Left B jumper, and Right B jumper as shown. I2S Left A IN Right A OUT IN Left B OUT Right B S/PDIF IN OUT IN OUT 11 3. Easy steps to configure the evaluation boards The GUI is required to configure the evaluation boards for different applications. Step 1: Double-click on the GUI Icon or shortcut to run the program. Step 2: Read the limited license carefully and click I Agree to proceed. Step 3: Make sure the evaluation board is turned on. Step 4: Connect the serial cable between your notebook/PC and the evaluation board. Step 5: Setup your Com Port in Com Port Settings. You need to setup your com port for the first time. There are 99 options to choose from COM1 to COM99. Click Apply to proceed. You should see READY in Module Status. If you see NOT FOUND, please check that the serial cable is not disconnected or loose. Step 6: At the top-left corner of the GUI, click Help, then click About. The current firmware version is shown as Evaluation Kit Version. The current GUI version is shown as GUI Version. 12 Step 7: Setup your choice of application in the Application Selection (Power-up Settings). Application Selection 2 Speaker ACK 3 Speaker ACK 4 Speaker ACK 2 Speaker NACK 4 Speaker NACK Headset 2 NACK down 2 ACK up Continuous RX or TX 2 Speaker ACK 44.1 2 Speaker NACK 44.1 4 Speaker NACK 44.1 Microphone Click Config to configure the evaluation board. ACK is the Active Acknowledgement protocol. MU will always acknowledge to CU for every packet received from the CU. NACK is the Not Active Acknowledge protocol. MU will only acknowledge to CU for packet not received within expected duration or when MU received an error packet. Continuous RX and TX is intended for RF testing only. 13 CU MU CU is the Central Unit or the wireless audio transmitter. MU is the Mobile of the wireless audio receiver. Stream enable Stream is the digital audio channel between the 3141 130 0034.1 and the MAXIM radio chip. Pipe is the digital audio channel between the 3141 130 0034.1 and the Wolfson Audio Codec and S/PDIF. By default, stream A, B, C, D are mapped to Pipe W, X, Y and Z directly. Stream A should always be enabled at the CU. E.g. Use Stream A and B in 2 Speaker ACK/NACK. Use Stream A and B (or C or D) in 4 Speaker in ACK/NACK. Use Audio Snooze (No Audio -> RF Off) This enables the CU to detect for the availability of audio signal at the input from the audio source. If no audio source is detected for 5 seconds, CU will enter Audio Snooze Mode and the LINK LED will turn off. Likewise, when CU enters Audio Snooze Mode, the MU will automatically enter Power Down Duty Cycle Mode PDDCM. In these modes, MAXIM radio chip is put to sleep. If audio source is detected at the CU while in Audio Snooze Mode, 3141 130 0034.1 wakes up the MAXIM radio chip and LINK LED turns on again. MU will also recover from PDDCM. By default, audio snooze is enabled. Use Power-on Sniffer This enables the CU to sniff or check for the best RF channel to communicate with the MU(s), upon power up. This feature is intended for co-existence with other 2.4 GHz wireless communication devices using IEEE802.11b/g WLAN, Bluetooth, DECT and microwave ovens. By default, power-on sniffer is enabled. Use SPDIF This enables the evaluation board to accept SPDIF digital audio signal. The CU will only accept SPDIF input, whereas the MU will only accept SPDIF output. See 2.1 CU Custom Settings and 2.2 MU Custom Settings. By default, I2S is used between the Wolfson Audio Codec and 3141 130 0034.1, hence CU will accept audio signal from Channel A/B, whereas MU will produce audio signal to Channel A/B. 14 Use Compressed This enables the CU and MU to transmit and receive respectively in compressed audio. By default, this is not enabled, thus uncompressed 16-bit audio is used. Use MU->CU Swap on Sniff Button This enables MU->CU swap feature, which can only be used when CU and MU(s) have this feature enabled. This feature is currently available in 2/3/4 Speaker NACK only. By default, MU->CU Swap is not enabled. Audio Snooze must be disabled and this is disabled by default. When Sniff button is pressed at the MU, it checks for a CU. If CU is found, CU and MU swaps. MU becomes the new CU and the old CU becomes the MU. If no CU is found, MU changes into a CU. When Reset button is pressed at the MU, if it is a new CU, it changes back to MU. When Reset button is pressed at the CU, it if is a new MU, it changes back to CU. Please check the audio input and output again after MU->CU swap. The new CU accepts audio input and the new MU produces audio output. 15 4. Connect Mechanism for Protected Pairing 4.1 Concept of Connect Mechanism Press this button on the CU and MU to enable the Connect mechanism for protected mode in which only the CU and MU(s) using the same Connect code can communicate. This differentiates the MU(s) that are connected to different CU(s) which are using different Connect codes. Only 1 CU can be connected to the MU(s) in the same protected mode. By default, the evaluation boards uses the open unprotected mode in which the CU and MU(s) not using any Connect code can communicate. The CU and MU will remember the connect code and the mode of operation (open or protected). 4.2 To establish protected mode: Step 1: Press this button only on the CU and MU(s) that must be connected. Step 2: Press this button on the MU(s) that must be connected. The RF LEDs will start to flash to indicate that the MU is ready to receive new Connect code from the CU. Step 3: Press this button on the CU. The CU will send a random 16-bit Connect code to the MU(s) that must be connected. The protected mode should be established within 30 seconds after the button is pressed. After 30 seconds, this will cease. After the protected mode has been established, only the MU(s) using the same Connect code with the CU can receive the audio streams from the CU. 4.3 To resume open mode or unestablish protected mode: Press Volume Up + Volume Down + Reset (or Off/On Power) together at the same time. If this is performed on the MU, only the MU is resumed to open mode. If this is performed on the CU, only the CU is resumed to open mode. This does not resume the MU(s) to open mode. 16
