Extension cable Zebra CBL-R20755-01 DB-9 Black

The Zebra CBL-R20755-01 is a 7 ft (2.1 m) straight extension cable designed to connect a scanner with an RJ50 modular jack to a host device with a DB9 female (RS232) connector. The cable provides a reliable serial connection for peripherals that require RS232 communication and extended reach between devices.

Advantages

This extension cable combines an RJ50 mod-jack on the scanner end with a DB9 female connector on the host end, offering compatibility with scanners and legacy serial ports. Its 7 ft (2.1 m) length increases installation flexibility while maintaining a straightforward, shielded connection suited for data transfer over RS232 interfaces.

Suitable for

• Connecting barcode scanners or similar peripherals with an RJ50 modular jack to a computer or terminal with a DB9 serial port
• Extending the reach of existing RS232 connections in retail, warehousing, or logistics environments
• Temporary or permanent installations where a straight, reliable serial extension is needed

Key specifications

• Cable length: 7 ft (2.1 m)
• Connector (scanner side): RJ50 modular jack
• Connector (host side): DB9 female (RS232)
• Cable type: Straight serial extension cable

How to use

Plug the RJ50 connector into the scanner’s modular jack and the DB9 female connector into the host device’s male serial port or into an adapter that provides a male DB9 connection. Ensure connectors are fully seated and secure any fastening hardware if present. Power on the devices and configure serial communication parameters (baud rate, parity, data bits, stop bits) on both ends as required by the connected devices.

Usage recommendations

Use this cable where RS232 serial communication is required and avoid running it parallel to high-voltage power lines to reduce interference. Verify pinout compatibility between the scanner and host before installation to ensure Tx/Rx lines are correctly aligned.
