Your kit is configured for 2-Nodes.  This kit is a digital wireless audio 1.0 
channel solution.  

Rx node has audio on left channel only.

2. Evaluation Kit Setup

This SP-205 Evaluation kit is pre-assembled and pre-configured to work of 
the box.  Follow the simple steps outlined below to correctly setup and 
begin using the evaluation kit.

 

1. Plug an audio cable into the audio jack on the Transmitter (Tx). Connect the 
other end of the audio cable to an audio source, such as a portable media 
player (Maximum input level is -3.5dBV).
2. Plug an audio cable into the audio jack on the Receiver (Rx). Connect the 
other end of the cable to an audio amplifier, active speaker, or headphones.*
3. Connect the battery pack or AC adaptor (6V DC, 400mA) to the power jack on 
the Tx and Rx.
4. Turn the power switches on both nodes to "on".
5. Make sure that antennas are in free space for best range, i.e. not resting 
against a surface, PCB, or body.

Audio signals will begin transmission after step 4.

Please note that because this evaluation kit is electrostatic sensitive, it is 
important to keep the Tx and Rx on electrostatic free surfaces.

*Headphones can be used for testing but since no headphone driver is included on the PB3 Rx board, the maximum 
volume level may be lower than desired.

3. Evaluation Kit Features

The SP-205 system comes preloaded with firmware.  This firmware implements 
a number of useful user interface features such as LED blinking and push button 
volume control.  This section provides a brief summary of some commonly used 
features of the firmware.  

A. Bond LED: 

The Bond LED displays the bond status between the Tx node 

and the Rx nodes, as follows: 

Solid On

Tx and Rx are bonded

Flashing 

Node is searching for bond with its mate

Off

Board is powered off

Bond1 LED will start to flash when the Tx is powered on.  When the Rx bonds to 
the Tx it will cause the Bond1 LED on the Tx and the Bond LED on the Rx to turn 
solid green. 

B. Mute LED: 

The Mute LED displays the audio status of the Rx node, as 

follows:

Solid On

Audio is manually muted by User

Off

Audio can play normally  

C. Volume / Mute Control:

 

Volume buttons on the Rx node will 

increase/decrease the volume audio level by 1dB per button press for a total of 
70 steps.  Pressing and holding a volume button will ramp the volume quickly.  
Maximum volume is 0dB and minimum volume is -70dB.  NOTE:  Volume 
settings are stored and recalled on reboots. (Normal Default Setting: Max for left 
channel)

The Volume and Mute buttons on the Tx node are currently not enabled.

D. Reset Button: 

Pressing the Reset button will reset the entire module. 

This button is sometimes useful when downloading new firmware.
