USB to 4 Port Serial Converter Lindy 42858

The Lindy USB to 4 Port Serial Converter (model 42858) connects up to four RS232 9‑way serial devices to a single USB Type A port. Its compact, bus‑powered design enables integration of legacy serial equipment with modern computers and supports common operating systems including Windows and macOS. Each serial port includes a reset button to help the host detect newly connected devices. An optional external power supply can be attached for use with high‑current serial peripherals.

Advantages

Compact and lightweight, the converter draws power from the USB bus for simple installation while offering the option to attach an external power supply when additional current is needed. The four independent RS232 ports provide reliable serial communication for multiple devices from one USB Type A connection. Built‑in reset buttons on each port simplify device detection and troubleshooting. Compatibility with Windows and Mac operating systems ensures broad platform support.

Follow your operating system prompts to complete any driver installation or configuration steps, if needed.

Recommendations

For stable operation in industrial or high‑load scenarios, use the optional external power supply when serial devices draw significant current. Keep serial cables at recommended lengths for RS232 to maintain signal integrity and use the port reset buttons to reinitialize devices after hot‑plugging.
