DELOCK 90582 USB 2.0 to RS-232 serial converter/repeater/isolator, FTDI FT231XS, green stainless steel

The DELOCK 90582 is a compact USB 2.0 to RS-232 serial converter based on the FTDI FT231XS chipset. Housed in a green stainless-steel casing, the adapter provides a direct serial interface for integrating legacy RS-232 devices with modern PCs. It is designed for internal installation in housings or on slot brackets and supports common power-management and modem signalling functions required for serial communications.

Advantages

This adapter offers a reliable USB 2.0 host connection with an RS-232 output, enabling communication with serial devices through a standard interface. The FTDI chipset ensures wide driver support and compatibility with Windows 10 (32/64-bit) and Windows 11, while the small form factor and metal casing make it suitable for installation inside enclosures or on expansion brackets.

Suitable for

When it may not be suitable

The converter provides a short built-in cable (maximum cable length 0.3 m) and is intended for internal or short-reach connections; it is not intended as a long cable replacement. It does not include external isolation accessories beyond the described repeater/isolator function and may not replace full galvanic isolation solutions required in some industrial environments.

Key specifications

How to use

Install the converter inside the PC chassis or on a slot bracket and connect the USB host pins to an internal USB header. Attach the RS-232 connector to the serial device. Install the appropriate FTDI driver on the host system if it is not automatically recognised, then configure the serial port settings (baud rate, parity, data bits, stop bits, flow control) in the application or operating system to match the connected device.

What to consider before purchase

Recommendations

Use the adapter for internal installations or close-proximity connections where a compact USB-to-RS-232 interface is required; ensure correct driver installation and serial port configuration for reliable communication.
