The N3680 scan engine is designed for integration into a wide range of OEM devices. The scan engine’s compact mechanical design can drop into many existing applications, allowing OEMs and third-party manufacturers to integrate the benefits of image-based scanning into a variety of devices, including hand held computers, PDTs, medical instrumentation, kiosks, diagnostic equipment, and robotics. The N3680 unit decodes linear, 2D, and postal codes.
The CF3680 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.
This User’s Guide provides demonstration and programming instructions for the N3680 scan engine and CF3680 2D imager module.
Honeywell’s bar code scan engines are factory programmed for the most common terminal and communications settings. If you need to change these setting, programming is accomplished by scanning the bar codes in this guide.
An asterisk (*) next to an option indicates the default setting.
After you open the shipping carton containing the OEM scan engine(s), take the following steps:
| Is the power on? Is the red or green aiming illumination line on? | If the aiming line doesn’t appear, check that: |
| • The cable is connected properly. | |
| • The host system power is on (if external power isn’t used). | |
| Is the scan engine having trouble reading your symbols? | If the scan engine isn’t reading symbols well, check that the symbols: |
| • Aren’t smeared, rough, scratched, or exhibiting voids. | |
| • Aren’t coated with frost or water droplets on the surface. | |
| • Are enabled in the scan engine or in the decoder to which the scan engine connects. | |
| Is the bar code displayed but not entered? | The bar code is displayed on the host device correctly, but you still have to press a key to enter it (the Enter/Return key or the Tab key, for example). |
| You need to program a suffix. Programming a suffix enables the scan engine to output the bar code data plus the key you need (such as “CR”) to enter the data into your application. Refer to "Prefix/Suffix Overview" on page 4-55 for further information. | |
| Does the scan engine read the bar code incorrectly? | If the scan engine reads a bar code, but the data is not displayed correctly on the host screen: |
| • The scan engine may not be programmed for the appropriate terminal interface. For example, you scan “12345” and the host displays “@es%.” Reprogram the scan engine with the correct Plug and Play or Terminal selection bar code. See Chapter 2 and Chapter 3. | |
| The scan engine may not be programmed to output your bar code data properly. For example, you scan “12345” and the host displays “A12345B.” Reprogram the scan engine with the proper symbology selections. See Chapter 6. | |
| The scan engine won’t read your bar code at all. | 1. Scan the sample bar codes in the back of this manual. If the scan engine reads the sample bar codes, check that your bar code is readable. Verify that your bar code symbology is enabled (see Chapter 6). |
| 2. If the scan engine still can’t read the sample bar codes, scan "All Symbologies" on page 6-76. | |
| If you aren’t sure what programming options have been set in the scan engine, or if you want the factory default settings restored, scan Resetting the Factory Defaults on page 142. |
