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.
