EXSYS EX-1311-2T USB 2.0 to RS-232 Serial Adapter Cable with FTDI Chipset, 0.8 m, Black

Where many USB-to-serial adapters rely on generic or cloned chips that drop connections under load, the EXSYS EX-1311-2T is built around a genuine FTDI FT232RL controller. That single choice changes everything for industrial automation, point-of-sale terminals, laboratory instruments, and legacy networking gear: you get rock-solid driver support across Windows, macOS, and Linux, plus a full hardware UART with 128-byte transmit and 256-byte receive FIFO buffers. The result is reliable RS-232 communication at up to 921.6 Kbps, even when multiple ports are active or the host system is busy.

Highlights

• Genuine FTDI FT232RL chipset – guaranteed compatibility and stable drivers
• USB 2.0 full-speed interface, bus-powered – no external power supply needed
• Standard DB9 male RS-232 connector with all handshake lines (RTS/CTS, DTR/DSR, DCD, RI)
• Supports data rates from 300 bps to 921.6 Kbps with automatic hardware/software flow control
• 15 kV ESD protection on the serial port (IEC 61000-4-2) for harsh environments
• 0.8 m cable length – ideal for connecting to nearby equipment without clutter

In daily use

Plug the USB Type-A connector into any free USB 2.0 port and the adapter enumerates as a standard COM port. On Windows 10/11, macOS, and most Linux distributions, the FTDI driver loads automatically – no CD or manual installation required. The DB9 male connector screws directly onto your device’s serial port, and the molded strain relief protects the cable at both ends. Because the adapter is bus-powered, it draws less than 100 mA and works reliably with laptops, industrial PCs, and embedded systems. The FT232RL’s internal EEPROM stores custom VID/PID and serial number settings if you need to lock the adapter to a specific application.
