NetO (Net-Oh) is the name for Opticon's protocol used for transferring data from our terminal devices to a host PC. Data is transferred as an entire file. Note that NetO must be supported on the application running on the terminal device and a host application must also be running such as NetO32. The necessary libraries to implement NetO protocol on the terminal devices are provided by Opticon in our C-Library Kit. A host SDK is also available to implement NetO within your own application.

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 OPL9815 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 filename 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.
