HandHeld Entertainment 4800i, 4600rp, 4600g manual Aimer Mode, Centering

Aimer Mode

Note: Concurrent is the default for units with 4X00 engines. Interlaced is the default for units with 5X00 engines. Refer to the Show Engine Revision on page 11-1for information on determining the engine in your unit. The 4600g, 4600r, 4800i, and 4600rp do not allow concurrent aimer mode.

The Aimer Mode feature allows you to lower peak current during scanning by alternating the aimer and illumination LEDs. When the Interlaced barcode is scanned, the aimer and illumination LEDs are not allowed to be on at the same time. Interlaced, the recommended setting for the 5X00 engines, limits the peak current draw during scanning. For 4X00 engines, the Interlaced setting reduces the frame capture rate. When the Concurrent barcode is scanned, the aimer and illumination LEDs are allowed to light at the same time. This is the recommended setting for the 4X00 engines. Select Off for fixed mount applica- tions when the aimer is not needed.

Centering

Use Centering to narrow the imager’s field of view to make sure the imager reads only those barcodes intended by the user. For instance, if multiple codes are placed closely together, centering will insure that only the desired codes are read. (Centering can be used in conjunction with Aimer Delay, page 3-11,for the most error-free operation in applications where multiple codes are spaced closely together. Using the Aimer Delay and Centering features, the imager can emulate the operation of older systems, such as linear laser barcode imagers.)

In the example below, the gray area is the full imager field of view and the white area is the centering window. Barcode 1 will not be read, while Barcode 2 will be.
