Product information

Description

The ROLINE 12.02.1174 serial cable provides a USB Type-A to RS-422/RS-485 interface in a compact, black inline converter. It enables modern computers with USB ports to communicate with industrial equipment and legacy serial devices that use RS-422 or RS-485 signalling. The cable is USB bus powered and supports plug-and-play operation for straightforward connection without an external power supply.

Advantages

This cable supports both RS-422 and RS-485 serial standards, allowing flexible use with a range of devices. It complies with USB 1.1 specifications and supports data rates up to 921.6 kbit/s, providing sufficient throughput for many configuration, monitoring and control tasks. The adapter is delivered with a DB9 female to 5-pin terminal block adapter and a user manual, simplifying installation and wiring. Compatibility with common Windows versions ensures easy driver support and setup.

Suitable for

Connecting industrial controllers, PLCs or sensors to a PC for configuration and monitoring
Integrating legacy serial equipment such as modems or measurement devices with modern computers
Field service and diagnostics where portable USB-to-serial access is required
Automation tasks that require RS-422 or RS-485 communication over a single USB port

How to use

Connect the USB Type-A plug to an available USB port on the host computer and attach the RS-422/RS-485 connector to the target device or use the supplied DB9-to-terminal adapter to wire individual signal lines. The cable draws power from the USB port and, on supported systems, will be recognised by the operating system for driver installation or automatic configuration. Configure serial parameters (baud rate, parity, data bits and stop bits) in the host application or device management software to match the connected device. For RS-485 networks, observe proper termination and signal polarity when connecting multiple devices.

Usage recommendations

Use shielded cabling and correct grounding practices in industrial environments to reduce electromagnetic interference. Ensure matching serial settings between host and device and apply termination resistors on long RS-485 runs or multi-drop networks to maintain signal integrity. For critical applications, test communication at the intended data rate and verify driver compatibility with the host operating system before deployment.
