Configure the Scanner

The output of this barcode reader can be modified in several different manners. Using several different tools. The following tools are available for you to use in configuring your scanner. Please submit a ticket above for assistance from Opticon's Technical Support Team.

Universal Menu Book

The Universal Menu Book (UMB) is a PDF document that enabled you to change the most commonly changed settings on Opticon's scanners. The UMB also contains information about what the various settings do when they are enabled. The UMB covers the following topics.

  • Interface Specific Settings
  • Code Opticons
    • Barcode Symbology Settings
    • Enabling/Disabling Symbologies
  • String Options
    • Prefixes / Suffixes
    • Preambles / Postambles
  • Read Options- Adjusting General Behaviors like:
    • Disable Trigger (Always On)
    • Single Read Mode / Multiple Read Mode
  • Indicator Opticons
    • Buzzer Settings
    • LED Settings


Opticonfigure serves primarily as a an online searchable Universal Menu Book (UMB), however it does have some notable differences. Opticonfigure is updated more frequently than the UMB. Opticonfigure also contains some menu options that were excluded from the UMB for the sake of brevity. Although more inclusive, Opticonfigure doesn't do as good of presenting information in an organized and comprehensible manner as the UMB does. Opticonfigure allows you to: Create and print custom configuration sheets. Create custom configuration sheets and save them as PDF files. Create custom configurations and export OCG files. Create DataWizard configuration sheets.


Data Wizard allows you to modify barcode data before transmission. Currently it is able to add or remove characters, adjust the length of the output data, and remove entire sections of the barcode prior to transmission. Commonly each configuration will be designed to match different sizes, symbologies, or characters in barcode data. So for example if a user wants to truncate a Code-39 barcode of a specific length, but add characters to a Code 128 barcode, you wold make two configurations.

Interface Types

The C37 supports multiple interface types, including USB-HID and USB-VCP. For a complete list see the About section above.

USB-HID Keyboard Emulation

If you have purchased a USB version of the C37, and your software doesn't require the use of a serial port then this will be the most convenient interface for you to use as it doesn't require the use of special drivers or middleware. You can simply place your cursor where you want the barcode data to go, point, and scan.

To use this interface, simply print this barcode sheet and scan each barcode on it from top to bottom. When you're done the C37 will be recognized as a USB Keyboard.

USB-VCP Serial Port Emulation

If your software requires the use of a serial port to transmit and receive data, then you must choose this mode if you own a USB C-37. First, download and install our USB Drivers. Then, print this barcode sheet and scan each barcode on it from top to bottom to configure the C-37 in USB-VCP mode. After this, your PC will automatically detect that the C37 is connected in Serial Port mode and will install the correct drivers.

You may also have to configure the PC-side software to listen on the correct COM port. To do that please contact your software vendor's Technical Support team.
