copying of audio materials.
9
Output to Amplifier:Connect the included ribbon cable to this connector and to
the corresponding connector on the MAS amplifier. This cable passes audio signals
from the controller to the amplifier, and it transfers DC power from the amplifier
to the controller. If this cable is ever damaged, do not use it, and contact Harman
Kardon for a replacement.

Description
The AT24C02B provides 2048bits of serial electrically erasable and programmable
read-only memory (EEPROM) organized as 256 words of 8bits each. The device is
optimized for use in many industrial and commercial applications where low-power
and low-voltage operation are essential. The AT24C02B is available in space-saving
8-lead PDIP, 8-lead JEDEC SOIC, 8-lead UltraThin Mini-MAP (MLP 2x3),5-lead
SOT23, 8-lead TSSOP, and 8-ball dBGA2 packages and is accessed viaaTwo-wire
serial interface. In addition, the AT24C02B is available in 1.8V (1.8V to 5.5V) version.
Note: For use of 5-lead SOT23, the
software A2, A1, and A0 bits in
the device address word
must be set to zero to prop-
erly communicate.
