TAP commands are sent to the SoundTouch wireless pedestal by connecting to the SERVICE connector on the back of the pedestal.
An ETAP cable and RS232 to TTL Converter are required for this communication. The ETAP cable is available from Bose (see part number above). The RS232 to TTL Converter is made by B+B electronics, model number 232LPTTL.
TAP commands are needed for the following procedures:
A. Wi-Fi Test
B. Serial Number Programing
C. Setting Wi-Fi Country Code
1. Tera Term Terminal USB Setup
Tera Term is a terminal emulator and can be downloaded at sourceforge.jp/ projects/ttssh2/. It is the interface used to send TAP commands to the SoundTouch wireless pedestal.
1.1 Connect the SoundTouch wireless pedestal to the Wave® Music system III using the Bose link cable on the pedestal.
1.2 Connect the Wave Music system III to AC power.
1.3 Connect the SoundTouch wireless pedestal to the computer.
# Connect the RS-232 to TTL converter to the COM port on the PC.
# Connect the TAP cable to the RS-232 to TTL converter.
# Plug the other end of the TAP cable into the SERVICE jack on the back of the SoundTouch wireless pedestal.
2. Teraterm Setup
2.1 Launch a Tera Term terminal window and select serial communication and port.

WI-FI TEST PROCEDURE
2.2 Select setup, then serial port to set the baud rate to 115,200 data to 8 bit, parity to none, stop to 1 bit and flow control to none.
3. Test TAP Communication
3.1 Enter TAP command “sys ver”. The system will respond with the software version similar to: BoseApp version: 1.0.17.11330.242810 epdbuild.rel_1.x.hepdswbld05.2013-06- 18T15:50:19.
Functional Tests
Wi-Fi Functional Test Set Up
This test uses TAP commands to connect the product to a Wi-Fi network and stream audio from a Bose URL. The Bose SoundTouch application can be used in place of this test. Note: Do not download the audio file from the test URL
Determine the security type for your router and select the appropriate TAP command for connecting to a Wi-Fi Router (WEP, WPA, or no security). Refer to  TAP Command Setup. Connect the SoundTouch wireless pedestal to the Wave Music system III using the Bose link cable on the pedestal. Connect the Wave Music system III to AC power.
1. Connecting to a Wi-Fi Router
1.1 Enter the following TAP command for your router security type setting. Do not enter parentheses.
1.1.1 WEP Security Type
airplay wep profile (SSID) (Password)
1.1.2 WPA Security Type
airplay wpa profile (SSID) (tkip or aes)
(Password)
1.1.3 No Security
airplay Wi-Fi profile (SSID)
1.2 Wait for the Wi-Fi indicator LED on the back of the unit to turn white. This may take up to a minute. While the unit is connecting, it will flash amber. If the indicator does not turn white, enter the TAP command again.
2. Testing the Wi-Fi Module.
2.1 Enter the following TAP commands.
Press the <enter> key on your keyboard after each command. You should see an OK response in the Tera Term dialog box. sys configuration DemoAudioURL worldwide.bose.com/downloads/assets/ audio/take5.mp3 <enter> sys configuration DemoNetworkEnabled true <enter>
demo enter <enter>
TEST PROCEDURES
2.2 The song “Take 5” should play. Listen for clean undistorted audio.
2.3 Enter the following TAP command to exit the Wi-Fi test.
demo exit <enter>
Note: A Tera-Term macro that includes these TAP commands is available for download on the product’s repair information page. Place the macro file in the same folder as your Tera-Term program. Open Tera-Term, select Control, Macro, wifi_test.ttl. Once the macro runs, follow the prompts.
