Datalogic CAB-548 RS-232 Black Extension Cable

The Datalogic CAB-548 RS-232 extension cable is a black connectivity accessory designed to extend the physical reach of RS-232 connections between barcode readers and host systems. It provides a straightforward wired extension to maintain reliable serial communication in environments where the reader and the host are separated by a distance that exceeds the original cable length. The cable supports standard RS-232 signal transmission and is intended for use with compatible Datalogic barcode readers and other devices that accept RS-232 serial connections.

Advantages

The cable offers extended reach without altering signal format, enabling devices to remain connected across greater distances while preserving serial communication stability. Its black jacket provides a neutral appearance that integrates into retail, warehouse, or industrial settings. The design focuses on durability for repeated plugging and routing in typical workplace environments, minimizing signal interruption and reducing the need for device relocation.

Suitable for

• Extending the connection between RS-232 barcode readers and point-of-sale or computer systems
• Connecting scanners to serial-controlled terminals in warehouses and logistics centers
• Temporary or permanent installations where increased cable length is required
• Workstations where device placement flexibility is needed without changing host locations

Key specifications

• Cable type: RS-232 extension cable
• Color: Black
• Intended function: Serial signal extension for barcode reader connections
• Compatibility: Designed for devices with RS-232 serial ports
• Physical characteristics: flexible jacket suitable for routing in retail and industrial environments

How to use

Connect one end of the CAB-548 to the RS-232 port of the barcode reader and the other end to the host system's serial port or to an existing RS-232 cable to extend its length. Ensure connectors are fully seated and any screws or locking mechanisms are secured to prevent accidental disconnection. After physical connection, verify communication by scanning a barcode and confirming data appears correctly on the host application. If needed, check serial port settings on the host for matching baud rate and parity to the reader's configuration.

Recommendations

Route the cable away from high-voltage power lines and sources of electromagnetic interference to maintain signal integrity. For long runs, keep cable length within recommended RS-232 practical limits and use appropriate grounding practices. Inspect connectors periodically for wear and ensure secure mounting to avoid strain on ports.
