Back-Focus Adjustment
The Excel cameras are designed with a lens mount insert to allow adjustment of the lens
position relative to the camera sensor. This is typically referred to as a “Back-Focus”
adjustment.
A brass insert is secured by a lock-ring. To adjust the lens position, loosen the lock-ring
with the included wrench by rotating the lock-ring counterclockwise. Turn the brass insert
clockwise to bring the lens closer to the sensor, and counter clockwise to increase the
distance until optimum focus is obtained. Then lock the setting by tightening the lock-ring
clockwise.

Software Development Kit (SDK)
The Excel cameras use the Unibrain IIDC driver and the Exponent software suite is built
upon the Unibrain Fire-i API. Documentation of the Excel camera feature set and the
conformance to the IIDC specification along with information on using the Unibrain SDK is
included in a “SDK” folder on the Exponent Software Installation Disk. Unibrain drivers are
provided for use with our Exponent Software Application as part of the Dage licensing
agreement with Unibrain. The Unibrain Fire-i API is available for customers who want to
develop their own software application based upon the Unibrain drivers. This provides a
continually updated SDK and support base for developers and the Dage Exponent
application alike now and in the future.
