Capturing Images

The image-capture process is a split-second operation for experienced users. By following the basic guidelines, new users can easily develop their own technique and, with practice, quickly learn to adapt it to different circumstances.

The basic steps for acquiring images using the Dolphin 7200 2D terminal are:

1.To aim, hold the Dolphin terminal horizontally at a 45° angle approximately 2 to 9 inches (5 to 20 cm) away from the target. You may have to adjust the angle at which you hold the Dolphin if there is glare on the screen.

2.Press the ON/SCAN button to take an image. Use the live video image on the terminal screen as a guide for positioning and aiming the terminal at the target. You may find it helpful to start by moving the terminal further away and then in closer to the target. The active screen image will have a slightly degraded appearance compared to the captured image. This is normal.

3.Release the ON/SCAN button to capture the image when the desired image is displayed on the terminal screen. Hold the Dolphin terminal as still as possible when capturing the image.

Image Quality and File Size

The image quality and related file size is determined by the data compression method used by your software application. For highest quality, take grayscale images. When saved, the image will be saved in JPEG file format. The size of the file depends on the information content of the image and will be approximately 4-8 K.

Lighting Conditions

The Dolphin 7200 2D terminal is designed to read bar codes and take images in dim light conditions. It is suggested that you turn on the unit's electroluminescent display backlight when taking images in extreme low light conditions to help with aiming.

Dolphin 7200 2D Demo Software

The Dolphin 7200 2D terminal demonstration software allows you to show terminal's ability to do omni-directional decoding, image capture and I.Q. Imaging.

The Image Capture demo requires that you have a PC available with a program such as the Dolphin File Transfer utility that is capable of receiving files via Ymodem protocol, and a Dolphin home base connected to that PC.

For more information on using the Dolphin File Transfer Utility, see Transferring Files to or from the Dolphin Terminal on page 6-9.

Re-Installing the Dolphin 7200 Demo Applications

The Dolphin 7200 2D terminal is shipped loaded with the demonstration software. If the demo software has been removed from your terminal, follow these steps to re-install it:

1.Download the demonstration installation programs from the Partners area of the web site: www.handheld.com. The program is called DEMOS.EXE and is a self-extracting zip file that installs the Demo applications and also offers to replace the Dolphin terminal's AUTOEXEC.BAT file.

2.Use the Dolphin File Transfer utility to load DEMOS.EXE onto the Dolphin unit.

3.Run DEMOS.EXE.

4.Start the demo program by typing DEMOSTART at the C:> prompt and then pressing ENTER.

If you chose to let DEMOS.EXE overwrite the AUTOEXEC.BAT, perform a three-key reset (pressing and releasing the SHIFT, ON/SCAN and BKSP keys at the same time.) and the program will start.
