Quick Start for the OPN-2001

Follow the instructions below to get started with the OPN-2001 on your platform.


Using the OPN-2001 with a Windows PC requires you to download and install Opticon's PC USB Drivers Installer, and an application to retrieve the data like the PC Companion Application. Both of these are located in the Downloads section of this page.

Initial Setup

You will only need to do this part once per computer.

  1. Download the "All-In-One PC Drivers" from the Driver Downloads section of this page. Run the installer you downloaded by double-clicking on it. Follow the prompts on your screen until the installation is completed.
  2. Download the OPN PC Companion Application which is also located in the Software Downloads section of this page.
  3. Open the compressed file, and run the OPN200X Setup.exe. Follow the instructions in the wizard to install the software. When it is finished installing, the PC Companion Application dialog will appear.
  4. Plug the OPN-2001 into your computer. Windows will inform you that it has found new hardware, and that it is installing the drivers for that hardware. Then you will see the status indicator in the application window turn green. From the application window you can download barcodes, change settings, or view and set the date and time on the device.

Scan Barcodes

Collecting data with the OPN-2001 is as simple as pointing and scanning. Scanning barcodes with the big button or "trigger" will store barcodes, while scanning with the small button or "function" will remove barcodes. Below are some tips about scanning and removing barcodes from the device.

  • When the OPN-2001 has a good scan, it will chime, the LED on the device will flash green, and the laser will turn off.
  • When the OPN-2001 deletes a barcode, it will give a different chime than above, and it will flash an Orange LED when it has a good scan.
  • Deleting the same barcode again when there are no more scans of it present will cause the OPN-2001 to chime for about a second. The LED will also flash red.

Download From the OPN-2001

If you haven't done so yet, refer to the Initial Setup instructions above to get all the proper software installed and ready. This part of the guide assumes that you have already successfully setup your computer to communicate with the OPN-2001.

  1. Plug the OPN-2001 into your computer.
  2. Open the OPN-2001 PC Companion Application by navigating to the Start Menu shortcut you created during the Initial Setup. This is usually in Opticon/OPN200X/OPN200X, and it will have an icon that looks like one of our OPN2001's.
  3. Double-check that the "Status" light is green.
  4. Check the box next to "Save to file" if you would like your barcodes to be saved to your computer each time you select "Get Barcodes." By default, the barcodes will be stored in the Documents folder on your computer. To change this, click on the ellipsis(...) button and choose where you would like your barcodes saved.
  5. Click "Get barcodes" to download the barcodes that you just scanned. Double-check that they got saved to your file before proceeding.
  6. Click "Delete barcodes" to erase the barcodes stored on the OPN-2001.


In order to set up the OPN-2001 on the Mac, we will need to install the Mac Companion Application and configure the OPN-2001 to connect to the Mac.

  1. To install the Mac Companion Application, download the "OPN-2001 MAC Companion Application" under software downloads. Open the resulting folder, and run the installer "Opticon OPN Demo Application.pkg." Follow the prompts until the installation is complete.
  2. Plug the OPN-2001 into the Mac. At this point the OPN-2001 should be recognized as a network interface.
  3. Start up the OPN-2001 Mac Companion Application using the Finder. It will automatically detect the OPN-2001. The connection can be confirmed by the green "Connected" text in the top right corner of the application.

The OPN-2001 and the Mac are now connected and working together.


There are currently APIs for developing applications to communicate with the OPN2001 on/with the following platforms/technologies:

  • Windows XP / Vista / 7 (32 and 64 bit)
  • ActiveX
  • .NET
  • Mac OS X

Setting the time on the OPN2001

To set the time on your OPN2001:

Using the OPN Companion Application

  • With the device connected, choose the button for "Set time".

Without companion app

If you are using your OPN2001 in any other mode please use Appload.

  • Once running Appload, select Settings > Port > Opticon Code Reader (1D) (COMX).
  • Then choose Utilities > Send time.

The time on your OPN2001 will be set to the time of your computer.

Factory Reset

To factory reset the OPN-2001 please follow the below instructions.

  • Ensure the OPN-2001 has sufficient charge (at the least the laser should come on with a trigger press when the unit is unplugged)
  • Disconnect the OPN-2001 from any USB connections
  • Press and hold both buttons (scan and clear) for 10 seconds
At the end of the time you will hear a single tone indicating successful reset. While holding the keys the LED will flash RED (If it flashes any other color you are not holding both buttons firmly enough).
Note: It is possible to disable the factory reset option of the OPN-2001 with the SDK (and subsequently our Standard PC Demo Application). If this is disabled this feature will not work until re-enabled.


The main OS functions as a batch mode scanner and requires the use of the Companion Application. The OS also supports the function of the USB-HID (keyboard) mode.

OPN2001-2003 comparison

Feature OPN2001 Standard Demo firmware OPN2001 HID firmware OPN2003 Standard application (OPN2001 emulator) OPN2003 Batch Demo application
Can the scanned data include a prefix and suffix? If yes, can the Prefix and the Suffix be more than one character (String)? This is not an option with the current firmware, however prefixes or suffixes could be added with custom developed PC side software. Currently return or tab are the only available suffixes, however other prefixes or suffixes could be added with custom developed PC side software. Yes, and yes up to 4 direct input entries. Please refer to page U85 of the universal menu book linked below for more information on prefixes, suffixes preambles, and postambles. http://www.opticonusa.com/pdf/Manuals/Universal_Menu_Book.pdf This is not an option with the current firmware, however prefixes or suffixes could be added with custom developed PC side software.
Does the scanner have an internal serial number that can be output as part of the scanned data? Yes, although we currently only have one PC side application that will put the serial number in the file with the scanned data, the "OPN2001 Data Downloader" application. No See "OPN-2001 Standard Demo firmware" Yes, this is a configurable option. Data is transferred using the NETO32 program or a custom program using the NETO protocol.
Can the scanner be setup to include scanned data time stamp? Yes, using most of our PC side applications including the "OPN2001 Data Downloader" application. Yes See "OPN-2001 Standard Demo firmware" Data stored as Database file (multiple scans of same barcode increases quantity rather than adding new lines to the file, also this means the time stamp only exists for the most recent scan of the specific barcode)


How to Configure the OPN2001 in HID Mode

  • Print the page linked here and scan the Keyboard Mode barcode.

How to Switch between HID Mode and Classic Mode

  • Print the page linked here.
  • Scan the "Batch Mode" barcode to configure the OPN2001 in Classic Mode.
  • Scan the "Keyboard Mode" barcode to configure the OPN2001 in HID Mode.

About Keyboard Mode

USB-HID (keyboard) mode allows the scanner to function as a batch scanner when disconnected from the computer and a real-time scanner when connected.

  • Real Time- To use the OPN2001 scanner as a real time scanner, configure it in HID mode, plug it into the computer and scan barcodes.
  • Batch- When disconnected it will store barcodes. You can then bring it back to the PC, and plug it in to retrieve the data. When the trigger is pressed the first time after reconnecting to a PC it will transmit all data off of the unit and onto the PC wherever the cursor happens to be (Excel, Notepad, etc).

Other Features

The newest revision of this firmware added some functionality. Users can now choose to transmit time stamps, and barcode IDs (barcode symbology). They can also switch between a "return" suffix, and a "tab" suffix.

If you would like to time stamp your barcode scans, or transmit the Barcode symbology(Code ID), you can do this by following the procedure below
  1. Print the barcode sheet at this link.
  2. To enable or disable either the time stamp or transmission of the barcode ID, scan the SET barcode, then the Enable or Disable barcode for either option, then the END barcode. These options are disabled by default.

By default, the OPN-2001 transmits an "Enter" key press after every barcode. To change this to a tab, or to change back to return, print this barcode sheet and scan SET, then the "Suffix for All Codes" barcode, followed by either the "Enter" or the "Tab" barcode, and finally END.


My OPN-2001 has suddenly stopped beeping when I scan barcodes. Is it broken?

It's possible that the beeper has been disabled using the beeper toggle feature. The beeper can be disabled or enabled without using a computer if you hold the large key for more than 10 seconds. To re-enable a disabled beeper, try holding this key for about 10 seconds. The OPN will sound a tone when the beeper is re-enabled.

I'm trying to integrate the OPN2001 ActiveX control with my Silverlight application, but when I try to create the opnCtl object, I get an exception. What's going on?

The OPN2001 ActiveX control doesn't expose an Automation API, which is why the exception occurs. See the MSDN article about using Automation here.

How can I communicate with the OPN2001 in my Java application?

You could utilize the native OPN2001 library via JNI, making a JNI wrapper for the exposed functions.

Will applications written for the OPN2001 work with the OPN2002 or OPN2003?

Yes, if the OPN2001 simulation application - a piece of firmware for the OPN2002 and OPN2003 - is installed. The application simulates the behavior and protocol of the OPN2001, making it compatible with your OPN2001 applications.

Is the serial protocol of the OPN2001 available?

No, we don't release that information. The recommended and authorized way of communicating with the OPN2001 is via its various APIs.

Is there a way to recover the saved data from an OPN2001 after the clear command has been sent?

Unfortunately no - the OPN2001 firmware erases the flash sectors where the data was stored upon executing the clear command. Make sure that the data has actually downloaded before you issue the clear command!

Is polling optional or required?

Polling is really meant to automatically detect when the OPN2001 has data, and then download it via a callback function. As such, it's not explicitly required.

The OPN-2001 is a small handheld wireless barcode reader capable of storing up to 10,000 barcodes at a time.


SDK for OPN200x Host Applications

There are currently APIs for developing applications to communicate with the OPN2001 on/with the following platforms/technologies: Windows XP / Vista / 7 (32 and 64 bit) ActiveX .NET Mac OS X The OPN PC SDK contains nearly everything you would need to develop your own host application to interface with the OPN-2001, OPN2003, or OPN2004. Sample code and documentation are included, however compilers are not included. Please use a compiler appropriate for the operating system you are developing for: Windows, or Macintosh OS X.
