Postnet Check Digit This selection allows you to specify whether the check digit should be transmitted at the end of Postnet data. Default = Don’t Transmit. Australian Post Interpretation This option controls what interpretation is applied to customer fields in Australian 4-State symbols. Bar Output lists the bar patterns in “0123” format. Numeric N Table causes that field to be interpreted as numeric data using the N Table. Alphanumeric C Table causes the field to be interpreted as alphanumeric data using the C Table.

9 - 1 9 Imaging Commands The scanner is like a digital camera in the way it captures, manipulates, and transfers images. The following commands allow you to alter the way the scanner performs these functions. Note: If you are using the scanner in a stand, you must set the In-Stand Sensor Mode to Off in order to take images (see In- Stand Sensor Mode on page 4-10). Single-Use Basis Imaging Commands with their modifiers send instructions to the scanner on a single-use basis, and take effect for a single image capture. Once that capture is complete, the scanner reverts to its imaging default settings. If you want to permanently change a setting, you must use the serial default commands (see Chapter 12). When the serial default command is used, that selection becomes the new, permanent setting for the scanner. Command Syntax Multiple modifiers and commands can be issued within one sequence. If additional modifiers are to be applied to the same command, just add the modifiers to that command. For example, to add 2 modifiers to the Image Snap command, such as set- ting the Imaging Style to 1P and the Wait for Trigger to 1T, you would enter IMGSNP1P1T. Note: After processing an image capture command (IMGSNP or IMGBOX), you must follow it with an IMGSHP command if you want to see it on your terminal. To add a command to a sequence, each new command is separated with a semicolon. For example, to add the Image Ship command to the above sequence, you would enter IMGSNP1P1T;IMGSHP. The imaging commands are: Image Snap - IMGSNP (page 9-1) Image Ship - IMGSHP (page 9-3) Intelligent Signature Capture - IMGBOX (page 9-10) The modifiers for each of these commands follow the command description. Note: The images included with each command description are examples only. The results you achieve may be different from those included in this manual. The quality of the output you receive will vary depending on lighting, quality of the initial image/object being captured, and distance of the scanner from the image/object. To achieve a high quality image, it is recommended that you position your scanner 4-6 (10.2-15.2 cm) away from the image/object you are capturing. Step 1 - Take a Picture Using IMGSNP Image Snap - IMGSNP An image is taken whenever the hardware button is pressed, or when the Image Snap (IMGSNP) command is processed. The image snap command has many different modifiers that can be used to change the look of the image in memory. Any num- ber of modifiers may be appended to the IMGSNP command. For example, you can use the following command to snap an image, increase the gain, and have the beeper sound once the snap is complete: IMGSNP2G1B IMGSNP Modifiers P - Imaging Style This sets the Image Snap style. 0PDecoding Style. This processing allows a few frames to be taken until the exposure parameters are met. The last frame is then available for further use. 1PPhoto Style (default). This mimics a simple digital camera, and results in a visually optimized image. 2PManual Style. This is an advanced style that should only be used by an experienced user. It allows you the most freedom to set up the scanner, and has no auto-exposure. B - Beeper Causes a beep to sound after an image is snapped.
9 - 2 0B No beep (default) 1B Sounds a beep when the image is captured. T - Wait for Trigger Waits for a hardware button push before taking the image. This is only available when using Photo Style (1P). 0T Takes image immediately (default) 1T Waits for a button push, then takes the image L - LED State Determines if the LEDs should be on or off, and when. Ambient illumination (0L) is preferred for taking pictures of color documents, such as ID cards, especially when the scanner is in a stand. LED illumination (1L) is preferred when the scan- ner is handheld. LED State is not available when using Decoding Style (0P). 0L LEDs off (default) 1L LEDs on E - Exposure Exposure is used in Manual Style only (2P), and allows you to set the exposure time. This is similar to setting a shutter speed on a camera. The exposure time determines how long the scanner takes to record an image. On a bright day, expo- sure times can be very short because plenty of light is available to help record an image. At nighttime, exposure time can increase dramatically due to the near absence of light. Units are 127 microseconds. (Default = 7874) nE Range: 1 - 7874 G - Gain Gain is used in Manual Style only (2P). Like a volume control, the gain modifier boosts the signal and multiplies the pixel value. As you increase the gain, the noise in an image is also amplified. 1G No gain (default) 2G Medium gain 4G Heavy gain 8G Maximum gain Example of Exposure at 7874E with fluorescent lighting:Example of Exposure at 100E with fluorescent lighting: Example of Gain at 1G:Example of Gain at 4G:Example of Gain at 8G:
