DeLOCK Adapter USB 2.0 Type-A to Serial RS-422/485 1m

This USB 2.0 to serial adapter from DeLOCK converts a USB Type-A port to a serial RS-422/RS-485 interface. It features a 1 m cable and a detachable 6‑pin terminal block suitable for solderless connections or installation in PC housings. The adapter is intended for connecting measuring instruments, POS systems, printers, modems, IoT devices and other equipment requiring RS-422 or RS-485 communication.

Advantages

The adapter supports both RS-422 and RS-485 serial standards and connects directly to a USB 2.0 Type-A port. A removable terminal block allows easy wiring and installation in enclosures without soldering. The 1 m cable length provides flexibility for desktop and rack-mounted setups, and the transparent and black finish helps integrate with different installations.

Suitable for

• Connecting measuring devices with RS-422/RS-485 interfaces
• Point-of-sale (POS) systems and peripherals
• Serial printers and modems
• IoT devices and industrial controllers
• Applications requiring solderless terminal block connections

How to use

Connect the USB Type-A plug to a host computer USB 2.0 port. Wire the RS-422 or RS-485 signals to the 6‑pin terminal block according to the connected device's pinout and grounding requirements; the terminal block can be mounted inside a PC housing or used externally for solderless connections. If necessary, supply 5 V to external devices via the terminal block according to the device specifications. Install any required drivers on the host system so the USB adapter is recognised as a serial COM port.

Recommendations

For reliable communication, verify correct wiring for RS-422 or RS-485 (differential pairs and GND), set appropriate termination and biasing where required, and ensure driver installation on the host computer. Use the 1 m cable length to reduce signal degradation in typical desktop or industrial setups.
