Σειριακό καλώδιο EXSYS EX-1309-9 Μαύρο 1,8 m USB Type-A DB-9

The EXSYS EX-1309-9 USB 2.0 to RS-232/422/485 cable provides a single high-performance 16C550-type UART compatible RS-232 serial port over a 9-pin male DB-9 connector. Designed for PCs, thin clients, notebooks and servers, it expands system COM ports instantly via a USB 1.1/2.0 Type-A connection without opening the computer. The cable is 1.8 m long, black, and weighs approximately 0.15 kg.

Advantages

This serial cable delivers reliable serial communication with a built-in 16-byte FIFO buffer (16C550), supports multiple serial standards (RS-232, RS-422, RS-485) on a single adapter, and draws power from the USB bus. Its plug-and-play design enables quick installation and immediate COM port expansion. Optional features include power over the DB-9 connector and support for an optional DIN-rail kit for rack installation.

Suitable for

• Connecting legacy RS-232 devices (modems, serial printers, instrumentation) to modern USB-only computers
• Industrial applications requiring RS-422 or RS-485 connections
• Field service, maintenance, and configuration of network equipment and controllers

How to use

Connect the USB Type-A plug to an available USB 1.1 or 2.0 port on your PC, notebook or server. Attach the DB-9 male connector to the serial device using the appropriate wiring for RS-232, RS-422 or RS-485 as required. The device is bus-powered by default; if using power over DB-9, ensure your connected equipment supports that option. Install any required drivers provided by the operating system or Exsys to enable the virtual COM port if the system does not automatically recognize the adapter.

Recommendations

Use shielded cabling and proper grounding in electrically noisy industrial environments. Verify signal wiring (TX/RX pairs or differential pairs) before powering devices, and choose RS-422 or RS-485 for long-distance or multi-drop installations.
