Interface Card EXSYS EX-1331VIS

The EXSYS EX-1331VIS is a versatile interface card designed to connect via USB and support RS-232, RS-422, and RS-485 serial interfaces. Housed in a durable plastic case, this device provides instant COM port expansion for PCs and notebooks. It integrates a high-performance 16C550-type UART compatible serial port equipped with surge protection and optical isolation to ensure stable and secure data transmission in demanding environments.

Advantages

This interface card offers reliable serial communication with built-in surge protection and optical isolation, safeguarding connected hardware from electrical interference and voltage spikes. Its compact design allows for easy setup without the need to open the computer system. The included screw-lock USB cable prevents accidental disconnections, ensuring a stable connection during continuous operation. Additionally, it supports flexible deployment options such as DIN-rail installation for rack environments.

Suitable for

• Connecting legacy serial devices to modern PCs and notebooks via USBIndustrial automation and control systems requiring RS-422 or RS-485 communication
• Point-of-sale systems and receipt printers
• Laboratory equipment requiring stable serial interfaces

When it may not be suitable

This interface card may not be suitable for applications requiring extremely high data transfer rates, as its maximum transfer speed is 0.0009216 Gbit/s with a 16-byte FIFO buffer. It is also not intended for consumer multimedia connections or non-serial peripheral integration.

How to use

To use the EXSYS EX-1331VIS, connect the device to an available USB port on your computer using the supplied locking USB cable. Install the required drivers compatible with your operating system, such as Windows 2000 or Windows 7. Once the installation is complete, connect your RS-232, RS-422, or RS-485 serial device to the port on the interface card. Configure the assigned COM port within your software application to begin communicating with the connected hardware.

What to consider before purchase

• Verify that your operating system version is compatible with the device drivers
• Confirm the required serial protocol (RS-232, RS-422, or RS-485) of your peripheral devices
• Evaluate whether the maximum data transfer rate and 16-byte FIFO buffer meet your application requirements

Usage recommendations

Ensure that drivers are correctly installed before connecting peripheral devices, and utilize the screw-lock mechanism on the USB cable to prevent accidental disconnection in high-vibration environments.
