Placing The Bass Module Into Tap Mode; Equalizer Programming Method - Bose Lifestyle PS 28 Troubleshooting Manual

Placing the Bass Module into TAP Mode

!
Place all four DIP switches to the down position before returning the unit to the customer
1. Place the bass module into TAP mode
1.1 Set all four DIP switches into the "up"
position. Apply power to the bass module using
the AC line switch and wait until the amber
LED blinks twice and the green LED blinks
briefly at least once (approximately 3 seconds
after power up). Then, within twenty seconds,
flip ALL four switches down, then flip switch #4
(closest to the RJ-45 connector) back up. The
unit will now communicate in TAP mode. The
amber and green LED will blink alternately
when no S/PDIF signal is applied. Note that
when TAP mode is activated in this manner,
the DSP will echo characters sent by the
terminal.

2. Verify the bass module communicates in
TAP mode.
2.1 Connect the test cable's, part number
264564, DB-9 connector to the RS-232 COM
port on your computer. Connect the test cable's
RJ-45 connector to the bass module.
2.2 Type the command ST S and hit "Enter".
The following response should be seen on your
computer screen. The results may differ de-
pending on the unit settings. If no S/PDIF
signal is applied, the sample rate will be 29
kHz.
SAMPLE RATE : 44101.30
SPKR TYPE : 02
DIP VALUE : 1111
LCRB_MUTE : 1
LSRS_MUTE : 1
SAT_CLIP : 1
BASS_CLIP : 1
EURO_BASS : 1
EURO_TREBLE: 0
2.3 Check the software by typing (issuing) the
command TN 4 and then hitting "Enter". A
typical response would be as follows.
03DE6455, 010808
03DE6455 is the checksum
010808 is the software version
Verify the changes have been made by typing
the command ST S.
The speaker type (SPKR TYPE) and other
information will be displayed. Decode the
numerical two digit speaker type as follows.
00 Falcon (Early version dual cube)
01 Doubleshots (Later version dual cube)
02 Cricket (Jewel ® Cube)
03 Dublin (Single Cube)
04 Mariner (151 environmental speakers)
