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 acti-
vated in this manner, the DSP will echo
characters sent by the terminal.
