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.

Example 3: Adjusting borders
Example 2: Adjusting numerical values
•RUN mode and IMAGE CONTROL screens display the pixel type the sensor is counting
(white or black), the pixel count, the captured image, and the judgment result.
The judgment result includes the percent above (+) or below (–) the Reference Count.
For example, if the (+) %Match is 15%, a pixel count that is 3% above the Reference Count is
displayed as Passed: + 3% because 3% is within 15%. A pixel count that is 25% above is
displayed as Failed: +25% because 25% is not within 15%. A value of 0% means that the
count is within 1% of the Reference Count. See page 24 for more information about how
judgment criteria is applied.
•To change a word value displayed next to an option, highlight the option and press ENTER to
toggle between choices (see Example 1).
•To adjust a numerical value displayed next to an option, highlight the option and press ENTER
to select its value. Press UP or DOWN buttons to edit the number. Press ENTER again to
deselect the value (see Example 2).
•To adjust ROI or mask borders, press UP, DOWN, LEFT, or RIGHT buttons (see Example 3).

SETUP Screen (#2)
After placing the target object within the sensor’s field of view, use this screen to adjust where the
image appears within the array, to focus the lens, and to lighten or darken the image.
While this screen is displayed, the controller continuously updates the image and runs the auto-
exposure routine to set the optimal exposure time, sensor gain, and gray-scale thresholds. These
values may be viewed and thresholds adjusted on the IMAGE CONTROL screen (#3.4) (see page
16).
Use LIGHTEN and DARKEN options to adjust the lower gray scale threshold. Values between -7 and 7
represent 15 steps of gray between the darkest and lightest pixels in the image.
➡To achieve optimal focus, turn the lens focus ring in small increments until the displayed Focus
value is the highest possible number. Remove your hand from the lens after each adjustment.
The value indicates the amount of contrast in the image. Higher numbers are achieved when
sensing images with greater contrast between light and dark areas.
➡To lighten the image, select LIGHTEN. Each time you press ENTER, the value is increased by 1
within a range of -7 to +7.
➡To darken the image, select DARKEN. Each time you press ENTER, the value is decreased by 1
within a range of +7 to -7.

This option is displayed only if an ROI or mask has been previously defined.
➡To clear a previously drawn ROI or MASK, select RESET and press ENTER.

Use this screen to define or remove Region of Interest (ROI) and mask areas. An ROI or mask
reduces the amount of area included in judgments or omits an area that could adversely affect
judgment.
ROI and Mask options are not available until a trigger is provided. If the application involves motion,
use an external trigger.
OPTIONAL: After adding an ROI, use the FOCUS option to re-focus the lens and select EXPOSE to re-
calculate and optimize the exposure time. Using the THRESH option to adjust gray-scale thresholds
may help improve the image.

TEACH Overview
TEACH Screen (#4)
If not using the QUICK START option, use TEACH screens to set judgment criteria.
The controller uses the maximum, minimum, and average counts obtained from good and
(optionally) bad examples to calculate acceptable ranges (%Match values). During subsequent
operation, a pixel count must be within the %Match ranges to receive a PASS judgment.
NOTE: If the sensor is taught using the QUICK START option or only good examples, the %Match
values are 15% above the maximum count and 15% below the minimum count. These values may
be adjusted automatically by teaching bad examples or manually on the EDIT JUDGE screen (#4.2)
(see page 20).
TEACH GOOD PRODUCT

TEACH BAD PRODUCT

to exit TEACH screens.
