Bose®Lifestyle®SA-2 & SA-3 Amplifier Software Upgrade
Steps:
1. Using the schematic shown in FIGURE 1, construct a cable for issuing TAP commands.
Obtain the most recent upgrade software at the following link:
http://intranet.bose.com/tsg/rog_support/cell-process/SA2-SA3%20Cell/SA2_3%20Prog%20Info.htm
2. Start a terminal emulator program on a PC (e.g: Hyper Terminal, Tera Term Pro). Also
found at the link listed above.
Note: The SA-2 or SA-3 should not be plugged in at this time.
3. Open Tera Term and select “serial” as shown below. Click OK.
4. Setup the terminal emulator as shown below. Tera Term terminal emulator is shown.
Set Up:
Baud Rate: 19.2K
Data: 8 Bit
Parity: none
Stop Bit: 2 Bit
Flow Control: None

5. Connect the TAP cable to the Bose Link connector on the SA-2 or SA-3.
6. Set all switches to high.
7. Plug the unit in. The SA-2 or 3 will go into a Pre Flash Load state: The LED will blink
fast, 4 times/second.
8. Within 25 seconds of plugging the unit in press the control key (CTRL) and then the F
key sequentially (may need to do two times) on the keyboard (SA-2 or 3 will go into a Flash
Erase Mode - LED either stops blinking or stays on for about 5 seconds) otherwise the
system times out from the flash loader (if this happens unplug the unit until the LED is
completely out, about 2 minutes, plug back in and continue).
9. At the end of the Flash Erase Mode the SA-2 and 3 goes into a Flash Load State (The
LED will start blinking 2.5 times/second). The code has now been erased.
10. To transfer the new code to the unit select File from the top menu, at that pull down
menu select Send file (the window seen below will pop up). Find the software that was
saved to your desktop in step 1 and double click. (The LED will blink slowly while the file is
loading about 1 time/second).
11. Once the file has finished the transfer the SA-2 or 3 will go back to the Flash Load State
(The LED will blink 2.5 times/second). At this time move switches 6 & 7 (for both the SA2
and 3) in the down position.
12. Unplug then unit and wait until the LED has completely dimmed. Re-plug the unit in.
The unit LED should blink at a normal speed. If this is the case the upgrade is complete, if
the LED does not blink normally please try this upgrade again.
