Compact high-density 2D fixed scanner

The B+n DS457-HD20004ZZCN is a wired fixed-mount barcode reader built for high-density 2D code capture. It targets electronics and pharmaceutical production lines where traceability and zero-footprint integration are required. The unit reads printed labels and mobile barcodes from phone screens without pausing between scans. Omni-directional scanning removes the need for precise alignment.

RS-232 integration and mounting considerations

Connection is via a single RS-232 interface, so the host must provide a compatible serial port or an active converter. The scanner draws power over the same cable, eliminating a separate supply but requiring the host port to deliver adequate current. The compact body fits tight kiosk or instrument cavities, yet the fixed optics demand a clear line of sight to the presented code. Drop testing to 30 inches concrete shows mechanical resilience, but the exposed window still needs protection from abrasive debris.

Verify host port and presentation geometry

Confirm that your system exposes a genuine RS-232 port with the correct pinout and voltage levels before ordering. Measure the working distance and angle your application presents barcodes to the imager; the fixed focus is optimised for high-density symbols at close range. Ensure the mounting surface can secure the unit rigidly, because vibration can blur dense codes. No other interfaces or wireless options are available on this model.

Questions about this item

How can I confirm the DS457-HD scanner is reading 2D codes correctly after connecting the RS-232 cable?

Scan a test 2D barcode and verify the data appears instantly on the host; the 624 MHz processor and fast sensor shutter speed provide immediate decode feedback with no pause between scans.

What comes in the box with the DS457-HD20004ZZCN kit and what must I source separately?

The kit includes the fixed-mount scanner and RS-232 interface cable; a compatible RS-232 host port and power supply for the host side are not included and must be provided separately.

Which version of the DS457-HD should I choose for high-density 2D barcode capture on a production line?

The DS457-HD model with part number ending in 20004ZZCN is optimised for comprehensive high-density 2D capture and full omni-directional scanning on production lines.
