Compact Fixed-Mount Scanner for 1D and 2D Codes

The B+n DS457-SR20004ZZCN reads both one-dimensional and two-dimensional bar codes, including direct part marks and codes displayed on mobile phone screens. Its fixed-mount design suits integration into kiosks, registers or production lines where hands-free scanning is required. The unit connects via an RS-232 interface for direct host communication.

Suited to Tight-Space Installations Needing

This scanner fits environments that demand zero-footprint mounting, such as retail counters, manufacturing cells or airport gates. It is not intended for handheld operation, wireless connectivity or USB-only host ports. Buyers needing cordless freedom or a different host interface should look elsewhere.

Straightforward RS-232 Integration

Mounting is simplified by the scanner’s 1.15 in height and 2.44 in width, allowing placement under counters or inside tight enclosures. The included RS-232 cable provides the sole connection path; ensure the host system offers a compatible serial port. Misaligned mounting angles or missing serial drivers are the most common setup issues.
