Serial Cable UNITEK Y-105A USB Type-A DB-9 Black 1.5m

The UNITEK Y-105A Serial Cable is a 1.5 m interface cable with a USB Type-A connector on one end and a DB-9 (RS-232) connector on the other. Designed to connect serial devices to modern computers and laptops that lack native COM ports, this cable converts USB signals to standard serial format for reliable data exchange. The black outer jacket provides a neutral appearance while the construction supports regular use in office, industrial, and home environments.

Advantages

The cable offers a straightforward single-cable solution for connecting legacy serial equipment to USB-equipped hosts without requiring additional adapters. Its 1.5 m length balances reach and cable management, and the fixed molded connectors reduce strain at contact points. The combination of USB Type-A and DB-9 connectors supports compatibility with a wide range of serial peripherals such as modems, industrial controllers, barcode scanners, and measuring instruments.

Suitable for

• Connecting RS-232 serial devices to desktop or laptop USB ports
• Programming or configuring industrial controllers and PLCs
• Data transfer from barcode scanners, scales and measurement tools
• Legacy equipment maintenance and diagnostics

Key specifications

• Cable length: 1.5 m
• Connector A: USB Type-A (male)
• Connector B: DB-9 (male/female as applicable to device connection)
• Colour: Black
• Function: USB-to-serial (RS-232) data conversion

How to use

Connect the USB Type-A plug to an available USB port on the computer or laptop. Attach the DB-9 connector to the serial port of the target device, ensuring proper orientation and secure seating. If required by the host operating system, install the appropriate USB-to-serial driver so the cable is recognized as a COM port. After connection and driver setup, configure serial communication parameters (baud rate, parity, data bits, stop bits, flow control) in your terminal software or device configuration tool to match the connected device.

Usage recommendations

Avoid sharp bends and excessive pulling on the cable to prolong connector and cable life. For intermittent desktop use, keep the cable length free from heavy foot traffic and avoid pinching at connector interfaces. If using with industrial equipment, secure connectors with any available screws or retention hardware on the device side and confirm signal settings before live operation.
