There are only two adjustments:

These adjustments will be pre-adjusted to the customer’s specific application at the

factory, therefore, in general will not require adjustments by the user.

The gain is adjusted by monitoring test point TV with a scope, adjusting the gain

potentiometer, R5, until the analog image pixel levels are set to approximately 2.0 volts

peak with the module imaged on the a standard white target similar to the standard white

copy or typing paper. (The probe should be grounded as close to the CIS module as

possible. If possibly right on the ground input lead, pin 5, of the I/O connector.)

Then DC reference level is adjust by monitoring test point TR and setting the voltage to

approximately 1.6 Volts by adjusting offset potentiometer, R4.

Mechanical Structure

Figure 6 is pictorial of the PI331MC-DR. It shows the mechanical dimensions of the

housing and its mounting hole locations. The “inactive zones” are the sector without

imaging sensors.
