Starting Up
Mounted Chip
The demo board is designed to work with the AS1100, the
AS1107 is mounted on the demo board. If another IC must be tested, please remove the AA cell “A”
from the board and disconnect the external power supply if connected.
The AS1107 can now be removed and exchanged with the AS1106 or AS1100.
Power Supply
External Interface
The demoboard can be controlled via the onboard microcontroller or through an external device. This
can be done with a standard 3-wire interface. Additionally there is a pin for the readback of data as well
as a ground pin, if such is required for the data line. Multiple demoboards can be cascaded if the
DOUT is connected to the DIN of the next board.

AS1751
The demo board is powered via a single AA cell “A” or through the external power connectors “C”. An AS1320 will
boost the input voltage to the required voltage. The maximum input voltage must not exceed 3.5V DC.
If the demoboard is battery powered please make sure a fully charged rechargeable battery or a new disposable
battery is in use. The

For a maximum of intensity the external power connection should be used.
