USB 2.0 to 4S Serial RS-232 Ports Adapter EXSYS EX-1334V

The Exsys USB 2.0 to 4S Serial RS-232 Ports Adapter EXSYS EX-1334V is a hardware solution designed to expand connectivity options by adding four RS-232 serial ports through a single USB interface. Built with a reliable FTDI chipset and 16C550-type UART compatibility, this adapter ensures stable and consistent data communication for legacy and industrial serial devices. Its compact design and included screw-lock USB cable allow for secure installation in professional environments without requiring internal computer modifications.

Advantages

This adapter provides an efficient way to expand COM ports on modern computers, thin clients, or servers that lack native serial connections. The integration of a dependable FTDI chipset ensures broad driver compatibility and reliable data transmission across various operating systems. The included two-meter USB cable features a screw-lock mechanism on the connector, preventing accidental disconnections in high-vibration or critical operational settings. Operating power is drawn directly from the USB bus, eliminating the need for an external power supply and simplifying desktop or rack setups.

Suitable for

• Connecting legacy industrial equipment, barcode scanners, and scales to modern PCs
• Expanding COM ports on office servers and thin clients
• Laboratory and measurement setups requiring multiple serial interfaces
• POS terminal installations needing stable RS-232 communication

When it may not be suitable

This device is not suitable for applications requiring high-speed network communication or non-serial peripheral connections, as it is strictly designed for RS-232 serial data protocols. It may also not fit environments where physical space is extremely restricted due to the dimensions of the external adapter box and cabling.

How to use

To set up the adapter, connect the included USB cable to an available USB port on your computer, thin client, or server, and secure the screw-lock connector to ensure a stable physical link. The operating system will automatically detect the hardware and assign the necessary I/O addresses and interrupts. Install the appropriate drivers if required by your operating system, and configure the COM port settings such as baud rate, data bits, and parity to match your connected serial device. Once configured, you can begin transmitting data between the computer and your serial peripherals.

What to consider before purchase

• Verify that your operating system supports standard FTDI serial adapters
• Check if your hardware environment requires physical screw-lock cable security
• Ensure your connected peripherals operate on standard RS-232 voltage levels
• Confirm that four physical serial ports are sufficient for your connectivity requirements

Usage recommendations

For optimal performance and stable communication, ensure that the latest device drivers are installed and that serial port parameters match the requirements of your connected hardware. Secure the USB cable using the provided screws in environments prone to movement or vibration to prevent unexpected disconnections.
