The unit inspection for SCALAR EVO Touch, available in the Workshop module, is an installation and verification tool designed to assist field engineers and customer service partners in seamless installation, deployment, configuration, and verification of EVO Touch units.

NOTE:

Only authorized users who are assigned the Technician role can access the Workshop module that is integrated with the SCALAR platform.

Capabilities

  • Installation verification overview: Provides a comprehensive overview of health statuses including Communication, Positioning, CAN Bus, Tachograph, Mass memory (RDD), and Digital Input.
  • Real-time monitoring for quick identification of any issues during the installation process.
  • Report generation: Generates a detailed report of the installation process, including information on each configured parameter and highlights any deviations or issues encountered during installation. Sends the installation report to a defined group of recipients.

Install, configure, and verify the SCALAR unit #

This section describes the installation, configuration, and verification of the SCALAR EVO Touch unit using the Workshop module.

The procedure below only uses a SCALAR EVO Touch unit as an example, but the procedure is the same for SCALAR EVO Flow and Flow v2.

  1. In the Workshop module, the Welcome to workshop page is displayed.
  2. Click the Unit inspection and more tile. The Connect to communication unit page is displayed.
  3. Do one of the following:
    • Scan the QR code displayed on your communication unit for about 3 seconds and at a distance
      of at least 15 cm.
      • NOTE:

      The QR code reader application is not required for scanning the QR. However, the web app must be assigned appropriate permission to access the hand-held device camera. You must have an active internet connection.

    4. OR

  4. Enter the serial number (IMEI) of the communication unit, and then click Continue. For example, if the serial number mentioned on the unit is ABC-123456789123456, the unit serial number will be numeric, which is 123456789123456.
    5. NOTE:

    The serial number is displayed on the device label.

  5. After hardware activation, click Continue. The Preparing unit for inspection dialog is displayed.

    6. After the unit is prepared for inspection, the SCALAR EVO Touch page is displayed.

    In the Inspect unit installation section, you can perform a step-by-step check to verify whether the communication unit is installed correctly and subsequently generate a report.
    In the Health status section, you can view the device health as described in the View device health status section.

    NOTE:

    The overall health status is displayed on each tile.
