  • Page 5: Introduction

    VERIFIER Introduction The REA MLV-2D is an instrument for verifying the quality of printed matrix codes and 1D codes. It is a stationary piece of equipment that must be connected to a PC over an Ethernet network. The PC runs the supplied analysis software and device drivers, and is used to display the verification reports.

  • Page 7: Software Options

    The coaxial lighting can be removed, to also enable the REA MLV-2D to be used with the normal standard 45° and 10° lighting. 90° coaxial lightning must be ordered for a new device and cannot be added later.

  • Page 8: Commissioning

    Following transportation, please consult sections 4.2and 4.3. The REA MLV-2D is delivered in a case or in a cardboard box with appropriate foam padding. This packaging should be retained for possible later transportation. If the REA MLV-2D is shipped without the original packaging, it should be packaged with enough padding to ensure that the device cannot move about in the shipping box.

  • Page 9: System Requirements

    Firewall: the firewall must allow network traffic to/from the REA MLV-2D. The REA software TransWin32 is a single-user application. The licence is linked to the REA verifier and not to the PC installation. The software does not need a dongle and multiple copies can be installed if required.

  • Page 10: Connecting Up

    The REA MLV-2D is supplied with two identical network cables. Figure: Network cables The REA MLV-2D is connected to the PoE power adapter using one of the two Ethernet cables. The socket labelled "P+D/OUT" on the power adapter is used to connect it to the device.

    (the device shows network errors) may occur during operation. If these faults become too frequent, the network will need to be segmented by network administrators or the REA MLV-2D will need to be connected to the computer using a separate network port (see the previous section).

    REA ADB is the Article Database: it is used for the management, creation and import of article data that is to be used in conjunction with the REA verifiers. The program is started by the operator when needed. The Article Database (REA ADB) is optional and works with the REA verifier only if the program licence has been purchased and then activated in the application.

    If a base plate is used that has a cut-out smaller than the camera's field of view, readjustment and recalibration work is required (see section 11). © REA Elektronik GmbH, 64367 Mühltal, Germany --- REA MLV-2D Manual Version 3 – 21/12/2015 Page 23 of 98...

  • Page 24: Removing The Coaxial Lighting

    The 90° coaxial lighting is mounted just like a base plate and is removed in the same way. The lighting is connected to the REA MLV-2D with a cable and plug connector. The connector must be unplugged carefully. A normal base plate must then be fitted, as described in the previous section.

  • Page 25: Correct Handling

    Correct handling General The REA MLV-2D is an optical instrument that features a camera and a built-in lighting system. The optics module (see section 4.8) must never be used as a handle. Falls and physical shocks will damage the REA MLV-2D.

    The term "aperture" is usually understood to refer to the aperture of a camera lens. This is not the case in this context. The aperture of the lens in the REA MLV-2D is given a factory-set preset that achieves the best compromise between the maximum possible depth of field and the minimum possible degree of diffraction.
