## Long description

MicroConnect USBADB25 transparent 1.8 m USB to DB9 is a lightweight serial adapter cable that connects modern USB-equipped computers to legacy RS-232 devices. The cable provides a USB Type-A connector on one end and a DB9 female connector on the other, enabling data transfer, device configuration and diagnostics without requiring an internal serial port. The transparent jacket makes internal wiring visible and the 1.8 m length offers flexible placement between host and device. The product complies with RoHS environmental standards.
Advantages
The MicroConnect USBADB25 cable offers plug-and-play compatibility with systems that support USB-to-serial drivers, simplifying integration with routers, modems, industrial instruments and serial consoles. Its lightweight construction makes it easy to handle and route while the transparent sheath lets users inspect the cable visually. The 1.8 m reach balances desk tidiness and freedom of connection, and its DB9 interface preserves standard serial signalling for reliable serial communication.
Suitable for
 Connecting USB laptops or desktops to RS-232 serial devices such as routers, switches and modems
 Interfacing with industrial controllers, PLCs and instrumentation that use DB9 serial ports
 Serial console access for configuration, firmware updates and diagnostics
 Data transfer between modern computers and legacy equipment that require standard serial communication
Key specifications
 Cable length: 1.8 m
 Connectors: USB Type-A to DB9 (female)
 Jacket: transparent, flexible material
 Weight: approximately 16 g
 Compliance: RoHS
 Application: USB-to-RS232 serial communication
How to use
Plug the USB Type-A connector into an available USB port on the host computer and attach the DB9 end to the serial port of the target device. If required by the operating system, install or update the appropriate USB-to-serial driver so the host recognizes a virtual COM port. Configure serial communication parameters (baud rate, parity, data bits, stop bits, flow control) in your terminal or configuration software to match the target device settings. Ensure connections are secure before initiating data transfer or device interaction.
Usage recommendations
Avoid bending the cable sharply near the connectors, and keep the cable away from strong electromagnetic interference sources. For stable connections in industrial environments, confirm driver compatibility with your operating system and, when necessary, use a grounded USB port or externally shielded routing to reduce signal disturbances.
