About

The OPL9728 is a wireless 1D terminal scanner, and is one of Opticon's most popular products. It runs a low-level firmware, typically called the "OS", and on top of that runs an application, which essentially drives the behavior of the device and exposes a simple user interface on the OPL9728's LCD screen. The application can be customized in order to change the behavior of the OPL9278, using Opticon's C-Library Kit and the Toshiba C Compiler. This allows end-users to create custom applications modeled around their barcode-driven processes, making the OPL9728 a simple and flexible solution for many business needs.


The OPL9728 is used in combination with a cradle (typically CRD9723) in order to charge the OPL9728's removable battery, transfer data serially to a host (using plain ASCII, XModem, or Opticon's NetO), and load new OS revisions and applications (using Opticon's Appload). Other types of cradles exist, including a dialup modem cradle and a GSM cradle, which OPL9728 applications can utilize with Opticon's TCP/IP Library.

Software Installation

In this section we step through installing both Opticon's USB drivers and NetO32.

Installing USB Drivers

If you are using RS232 please skip to Installing NetO32. Opticon's USB drivers need to be installed for the cradle to be properly via USB.

  1. Download the USB drivers from the Driver Downloads section.
  2. Open the zip file by double clicking on it.
  3. Launch the installer by double clicking on it.
  4. Follow the prompts to finish the installation.

Installing NetO32

The OPL9728 uses a piece of windows software called NetO32 to save the data file to the computer. To install NetO32 follow the steps below.

  1. Download NetO32 from the Software Downloads section.
  2. Open the zip file by double clicking on it.
  3. Launch the installer by double clicking on it.
  4. Follow the prompts to finish the installation.

Configuring NetO32

  • Select 'Tools' > 'Options'
    • Choose RS232 from the menu at left
      • Choose the COM port for your cradle (COM 1 if using RS232, check Device Manager for USB ['Start' > 'Run' > 'devmgmt.msc' > click 'OK' and look under the 'Ports' section])
      • Change Baudrate to 115200
      • Change IrDA Device to 'None'
    • Choose 'Download' from the menu at left
      • Click the 'browse' folder icon at right to change the destination folder of the file once you have downloaded it.
      • Choose between 'Append', 'Overwrite', and 'Unique' to determine what happens when you download a data file but a file by that same name is already present.
    • Click 'OK'
  • Select 'File' > 'Save As'
    • Choose a file name appropriate for you (such as your name or your company's name) to save the settings you just changed.
    • Now every time after this that you open NetO32 you must select 'File' > 'Open' and choose this file to load your settings.
  • Select 'Protocol' > 'Start'

NetO32 is now in 'Polling' mode. Note that you should see the yellow light on the cradle blinking steadily. This means it will sit here indefinitely sending queries to the cradle and waiting for the right response to start a download. Multiple downloads can all be done without ever closing NetO32. When you are done using NetO32 simply select 'Protocol' > 'Stop' and NetO32 will discontinue polling mode. The application can then be closed.

Starting the Upload from your OPL9728

After NetO32 is in Polling mode (see above) follow these steps. Note that you should see the yellow light on the cradle blinking steadily. This means it will sit here indefinitely sending queries to the cradle and waiting for the right response to start a download. Multiple downloads can all be done without ever closing NetO32. When you are done using NetO32 simply select 'Protocol' > 'Stop' and NetO32 will discontinue polling mode. The application can then be closed.

  • For the purposes of the inital test, please scan some barcodes if you have not yet done so.
  • Select 'Send Data' from the main menu (use the arrow keys to move up and down and trigger (center key) to select an option.
  • The screen that appears should say 'Transmit Data via Cradle NETO Protocol -PRESS ANY KEY-'. Press any key.
  • The unit will change to say 'Sending File Waiting NetO Connection ...'. At this point simply place the unit on the cradle.
  • The OPL9728 will emit a series of short beeps and display 'File Was Sent. Delete Data File?'. Choose either YES or NO by pressing the appropriate arrow button below the display.
  • The NetO32 status log will indicate that the data was downloaded.
  • Your Data File is now on the PC in the folder specified previously.

FAQ

Are there diagnostics available on the OPL-9728?

Yes, there is a simple diagnostic routine built into the OS Firmware. To access it, press the Left+Trigger+Right keys at the same time to access the System Menu. Scroll down until you see Diagnostics. Select that option, and follow the instructions on the screen to continue.

How do I load my application onto the OPL9728?

Please see the Loading Firmware section located above.

How do I load a new OS (firmware) onto the OPL9728?

Same steps as loading an application;Please see the Loading Firmware section located above.

How do I get the saved scan data off the OPL9728?

There are a variety of methods. The most common is to use NetO32. Directions for this method are in the Setup section. Opticon's NetO file-transfer protocol is used to transfer the scan data as a flat file (typically .txt, .csv, or .dat; however you create and format the file in your embedded application), which requires NetO32 to be run on the PC.
You can send the data as plain ASCII text over the cradle's COM port, which would require a program or RS232 Monitor on the PC to read the incoming data and somehow save it.
You can use the XModem protocol over the cradle's COM port. You can also beam the data wirelessly with IrDA, or build the OPL9728's TCP/IP Library into your application to transfer the data as an email, over FTP, or some other Internet protocol. There are functions and libraries available for each of these options in the C-Library Kit.

Development

What programming languages can I use to develop embedded applications for the OPL9728?

The C programming language only.

What functions are available to me when developing my embedded application?

If you've installed the C-Library Kit, you should see a directory for OPL's. This contains various libraries, sample code, and demonstration applications to assist you in your development. The lib.h file in this directory contains all of the functions available to you when developing your embedded OPL9728 application. Also, if you go to the Start menu, under Program Files -> Opticon C-Library Kit, you'll see a programming help file (.chm). This contains descriptions of all the functions, return values, code demonstrating the use of the functions, and many other things. Beyond that, the standard ANSI C functions are available to you, so long as you include the proper header files in your source code.

How do I compile my application?

You have to use the Toshiba C Compiler, which you can purchase from Opticon. Versions 1.10 and later run on all Windows OS flavors. After that has been installed (preferably before installing the C-Library Kit, as the installer for the C-Library Kit prompts you for the root path of your Toshiba C Compiler installation in order to generate correct path information for build scripts) check out some of the example applications in the OPL folder where you installed the C-Library Kit. There you'll find build scripts (m.bat or mdemo.bat) that you can use and edit for your application, which you then run from the command prompt to build your application.

Is there a debugger to debug my application?

Unfortunately, no. Debugging is typically done through creating a log file within your application, printing information to the OPL9728's LCD screen, or some other method. Typically, applications are not of the size and complexity that this would be overly problematic.

How do I delete saved scan data (files) on the OPL9728?

See the remove() function.

How can I use Universal Menu Book commands to change the behavior of my OPL?

In code, you can use the systemsetting() function to set certain settings by default. For example, if you wanted to transmit UPC-E as UPC-A, you could put the following function call in your application:
systemsetting("6P");
