OVERVIEW
Product Overview
The PresencePLUS™ Model PRC1 Controller is a hand-held remote
programmer for the PresencePLUS™ Model P1B65Q Pixel-Counting
Sensor. The controller is used to program the sensor and monitor sensor
performance.
The controller easily attaches to the sensor with a modular coiled cord and
obtains power from the sensor for operation. The controller writes all
programmed parameters to the sensor. After programming the sensor, the
controller may be detached and used with another sensor.
Programming options, monitoring options, and captured images are
displayed on the controller's LCD screen. Arrow buttons on the controller's
keypad are used to select options, adjust values, and navigate from
screen to screen. Function buttons provide quick access to the most
frequently used screens.
Depending on the sensing application requirements, programming the
sensor involves up to three steps: SETUP, ROI, and TEACH.
In the first step, the SETUP mode is used to adjust the target object within
the sensor's pixel array, run the auto-exposure routine, focus the sensor's
lens, and lighten or darken the image.
In the second step, the ROI mode may be used to define a Region of
Interest (ROI) within the array for judgment or to mask an area to exclude
from judgment.

In the third step, the TEACH mode is used to "teach" the sensor to
recognize good and (optionally) bad images by presenting a number of
product examples. The controller uses the pixel counts from these
examples to determine judgment criteria for subsequent sensor operation.
Judgment criteria may be manually adjusted.
If the application does not require defining an ROI, masking, or teaching
bad product, the QUICK START option provides a simple one-step
SETUP, TEACH, and RUN sequence. The resulting judgment criteria may
be manually adjusted.
CONFIGURE screens are used to program parameters that typically only
need to be set once. Configuration parameters include selecting the
application type (to enable the most appropriate auto-exposure settings),
which pixel color to count (white or black), lighting options, trigger settings,
and output settings.
Up to four different sets of parameters may be uploaded from the sensor
to the controller and saved as files. This feature allows parameters to be
downloaded to the sensor when setting up different product runs or
programming more than one sensor.
After the sensor has been programmed and configured, the controller is
used to put the sensor into RUN mode. While the sensor is in operation,
RUN screens may be used to monitor PASS/FAIL and pixel count
statistics, view captured images, or adjust configuration settings and gray-
scale thresholds.
