Compact 2D Barcode Scanner DS457-SR20004ZZCN

The B+n DS457-SR20004ZZCN is a fixed-mount 1D and 2D barcode reader designed for tight retail, manufacturing or access-control installations. Its small form factor allows mounting directly on a register or under a counter where counter space is at a premium. Workers can capture codes as fast as items are presented without pausing between scans. The RS-232 interface connects directly to legacy POS or industrial controllers.

Replaces Bulkier Handheld or Larger Fixed Scanners

This scanner suits operations moving from handheld gun-style readers or older fixed-mount units that demand more mounting depth. The jump is worthwhile when a zero-footprint device is required to keep work surfaces clear or when direct part marks and mobile phone screens must be read reliably. It is not for buyers who need wireless freedom, USB or Ethernet connectivity, or a built-in display for verification.

Simple RS-232 Cable Kit Installation

The kit includes the necessary RS-232 cable for a direct wired connection to the host system. Mounting uses the unit’s compact 1.15 in. height by 2.3 in. length by 2.44 in. width profile (2.92 cm by 5.84 cm by 6.2 cm) with standard screws or brackets. Common issues include mismatched baud-rate or parity settings on the host port and insufficient power from the serial interface if the host does not supply the required current.

Questions about this item

What are the physical dimensions of the DS457-SR20004ZZCN for mounting?

The scanner measures 1.15 in. H x 2.3 in. L x 2.44 in. W (2.92 cm H x 5.84 cm L x 6.2 cm W), allowing a zero-footprint mount on a register or under a counter.

How is the RS-232 cable kit installed on the DS457-SR20004ZZCN?

Connect the RS-232 cable to the host port and secure the scanner in its mount; the step often missed is ensuring the host COM port settings match the scanner defaults before the first scan.

What maintenance does the DS457-SR20004ZZCN require over time?

Clean the scan window periodically with a lint-free cloth to maintain read performance on 1D, 2D and direct-part-mark codes; no user-replaceable parts are specified.
