Serial cable Unitek Y-105 — USB Type-A (male) to DB-9 (male), 1.5 m, black

The UNITEK Y-105 Black 1.5m USB Type-A DB-9 serial cable connects devices with a USB Type-A host port to equipment using a DB-9 serial interface. With a 1.5 meter length and a black finish, the cable is designed to provide a straightforward wired link for data transfer, device configuration, and communication tasks where a standard USB-to-serial connection is required.

Advantages

This cable combines a USB Type-A connector and a DB-9 connector in a single lead, enabling compatibility between modern computers and legacy serial devices without requiring additional adapters. The 1.5 m length balances reach and cable management, while the black color provides a neutral appearance suitable for offices, workshops, and server rooms. The construction is intended for reliable signal transmission for serial communication tasks.

Suitable for

• Connecting PCs or laptops with USB Type-A ports to serial devices such as modems, routers, industrial controllers, and instrumentation
• Firmware updates and configuration of network equipment that use DB-9 serial consoles
• Point-of-sale terminals, barcode scanners, and other peripherals that require a DB-9 serial link

Key specifications

• Connectors: USB Type-A to DB-9 (9-pin serial)
• Cable length: 1.5 m
• Colour: Black

How to use

Connect the USB Type-A plug to an available USB port on your computer or host device and attach the DB-9 connector to the serial port of the target device, ensuring correct orientation of the DB-9 connector. If required by the operating system or target device, install or enable the appropriate USB-to-serial driver before establishing communication. After connection and driver installation, open the terminal or configuration software on the host and select the corresponding serial (COM) port and appropriate communication parameters (baud rate, parity, data bits, stop bits) to begin data exchange.

Usage recommendations

To maintain reliable serial communication, use an appropriate driver supplied by the host or chipset manufacturer, avoid excessive bending near the connectors, and secure connections to prevent intermittent contact during configuration or data transfer.
