PR-5 2D Imager Module Installation Guide 1
GETTING STARTED
What is the PR-5?
The PR-5 0 is a 2D imager module designed to be integrated into fixed mount enclosures,
such as a self-service kiosk. It is optimized to read 1D and 2D bar codes on mobile phone
screens, coupons, loyalty cards or tickets at close reading distances. The module includes the
following:
•JE-238 scan engine
•USB interface (USB-B connector)
•Exit window
•Movement detector
•User feedback pins
Required Accessories
•Standard USB-A to USB-B cable

Mechanical Dimensions
The PR-5 is designed for OEM kiosk integrations and is EVA (European Vending
Association) compatible (dimension, exit window, and mounting holes).
Units are in millimeters
Connect to the Host
The PR-5 is connected to the host using a standard USB-A to USB-B cable (not provided). The
default interfaceis USB PCKeyboard. To select a different interface, see Configuration on page
6.
1. Connect a standard USB cable (standard USB-A to USB-B) to the PR-5 and to the USB port
on the host.
2. Power-up the host.
3. Verify that the PR-5 is on by presenting a bar code in front of the scan window. The white
LED should turn on and read the bar code.
Note: The PR-5 does not beep to indicate a good read unless this has been setup by the user with the
user feedback pins (see User Feedback Pins on page 8).

5
Distance Selection Switch
The PR-5 is equipped with a movement detector that triggers the scanner when
an object is detected. It is configured using the distance selection switch located
on the PCB. The CF3680 can detect objects from contact (on the exit window) up
to 30 cm (12 inches) ±15% (typical tolerance - for reference only).
Switch
•Position 1—0 to 10 cm (4 in)
•Position 2—0 to 20 cm (8 in)
•Position 3—0 to 30 cm (12 in)
Note: Only position 1 is indicated on the PCB.

Configuration
You can configure your scanner two ways:
Reading configuration bar codes
Using the JADAK ImageView scanning tool
Configuration Bar Codes
Scan configuration bar codes to set up your scanner. All available configuration bar codes are
available in the JADAK JE-238 User’s Manual. Contact your local JADAK representative for more
information.

JE-238 User’s Manual.
Interface
For USB serial interface, you must install the USB driver before connecting your scanner. Contact your
local JADAK representative to get the latest USB driver.

User Feedback Pins
User feedback pins give access to certain pins on the scan engine so the customer
can add additional functions.

Connector
Use a compatible connector with a 2.54 mm (0.1 inch) pitch and 2.54 mm (0.1
inch) row spacing (for example Molex P/N 22-55-2061).
Beeper (Pin 2)
Pin 2 (nBEEPER) provides a PWM output for generating audible feedback to the
user. This signal is used to indicate the status of the device using a variety of
patterns and frequencies.
This signal is driven by an Open Drain NC7WZ07 device with a VOmax = 5.5V through
the 100K pull up resistor on the engine.

Installation Recommendations
•Do not cover the exit window with another window or replace it with a
different window.
•Do not block the movement detector or place anything in front of it.
•Avoid direct light shining in to the scanner.

MAINTENANCE
Clean the Exit Window
The exit window is made of chemically strengthened glass and is scratch resistant.
To clean the window, use one of the following:
•Sani-Cloth®HB wipes
•Sani-Cloth®Plus wipes
•Super Sani-Cloth®wipes
•Isopropyl Alcohol wipes (70%)
•CaviWipes™
•Virex®256
•409®Glass and Surface Cleaner
•Windex®Blue
•Clorox®Bleach –10%
•Gentle dish soap and a small amount of water (PR-5 is not waterproof)
Note: For best scanner and movement detector performance, do not cover the existing exit
window with another window or use a different exit window.
Exit Window Replacement
If the exit window becomes scratched or damaged it can be replaced.
Caution: To prevent injury, use the protective gear as specified in the
procedure.
What You Need
•Protective eye wear

15
•Cut resistant gloves
•Pry tool (such as a spudger) made of plastic or with a plastic tip
•Cotton tipped applicators
•Isopropyl alcohol
Replace the Exit Window
To replace the exit window:
1. Put on the protective eye wear and cut resistant gloves.
2. Insert the edge of the pry tool under the edge of the glass window. Slowly
apply pressure to pry glass away from the plastic housing.
3. Once the glass is released, lift it way from the housing.
4. Remove remaining adhesive material around the window and clean with
isopropyl alcohol and a cotton tipped applicator.

16
5. Inspect the interior and clean/remove any dust or debris.
6. Open and remove the top plastic cover on the new window with red release
paper facing upwards.
7. Remove the red release paper.
Do not touch the window with your fingers!
8. Carefully apply the window (tape side down) onto the housing like the
previous window.
