1 Introduction The 3141 130 0034.1 demonstrates a myriad of possible wireless audio applications on the 3141 130 0034.1 module that features the capability of 3141 130 0034.1 chip designed and developed by STS for robust wireless audio experience. Some application examples include: 1. Wireless broadcast stereo headphone or speaker system for multi-room environment 2. Wireless discrete channel headphone or speaker system for multi-room environment 3.
The interface board IB provides different input/output I/O as shown below in figure 1.2b.

The adaptor board AB has two interfaces. The 30-pin FFC connector interfaces the IB. The 26pin FFC connector interfaces the 3141 130 0034.1. This is shown in figure 1.2d. IB Interface 3141 130 0034.1 Interface Figure 1.2d Adapter Board 1.3 Powered by Battery Pack (May Not Be Included) The evaluation board can also be powered by a 4-AA battery pack (NiCd, NiMH or Alkaline or normal) as shown in figure 1.3. The plug is configured as a standard DC jack with outer rim (5.2mm) to Ground (-) and inner rim (2.
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.
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).
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.
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.
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.
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.
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.
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 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.
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.
