Mirror image 2D code reading function (REVERSE)

This function makes it possible to read a mirror image 2D code label.

The mirror image 2D code reading is enabled, the time required for reading may increase.

DECODE LEVEL

You may set the decode level. Decreasing the level value increases the code reading efficiency, but the

BHT might misread low-quality codes (split or stained). To the contrary, increasing the level value

decreases the code reading efficiency, but it will diminish the possibility of misreading.

The setting range of the level value is from 1 to 9 and the default is 4

SCAN MODE

You can select the scan mode from the following:

NORMAL: Normal Reader mode

POINT: Point Scan mode

BARCODE: Barcode Reader mode

Point Scan mode: If you enable the Point scan mode, you can aim a target code by matching up the

center of the marker with that code. If there is no code within the range of the center or the scanner

cannot detect the marker due to the high levels of the lighting, the scanner cannot read anything. The

Point Scan mode takes effect only when the marker is permitted to light.

Barcode Reader mode: If you enable the Barcode Reader mode, you can read a barcode only. The

Barcode Reader mode limits the vertical readable area to 15% at the center portion, as shown below,

and the skew angle within the range of 0° ≤ θ ≤ 6°.

In this mode, the scanning time required is shorter than that in the Normal Reader mode.

However, the scanner cannot read 2D codes or multi-line barcodes.
