Fixed-Mount 1D/2D Scanner

The B+n DS457-SR20004ZZCN is a fixed-mount barcode scanner built for continuous 1D and 2D capture including direct part marks. It targets retail checkout lanes, manufacturing cells and airport gates where operators present items in rapid succession without pausing between scans.

Compact RS-232 Integration

The unit 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) and ships with an RS-232 cable for direct host connection. Its minimal footprint allows mounting on a register or under a counter, though installers must verify cable reach and secure a stable mounting surface to avoid vibration-induced misreads.

Pre-Installation Checks

Confirm the host system provides an available RS-232 port or a compatible serial adapter before ordering. Verify that ambient lighting and barcode print quality meet the scanner’s depth-of-field requirements for mobile phone displays and printed labels. Ensure the mounting location offers clearance for the stated dimensions and that power is supplied through the host interface.

Questions about this item

How can I confirm the DS457 scanner is reading 1D and 2D codes correctly after mounting it?

Watch for an instant decode beep or LED flash on every scan; the scanner captures codes as fast as items are presented with no pause needed between reads.

What does the DS457-SR20004ZZCN package include and what must I source separately?

The box contains the fixed-mount scanner and an RS-232 cable; you will need to provide a host port or adapter that accepts a standard RS-232 connection.

Which DS457 variant suits a tight mounting space such as a cash-wrap or manufacturing cell?

The SR20004ZZCN model 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), making it the smallest footprint in the DS457 series.
