Product information

Description

The Sunix SER5056A is a high-performance PCI interface card designed to expand your PC capabilities by adding four independent RS-232 serial ports. This universal communication board is engineered to support both 32-bit and 64-bit PCI architectures, ensuring compatibility with a wide range of computer systems using 3.3V or 5V bus power. Equipped with the advanced SUN1999 UART controller, this card provides reliable data transmission and is built to meet the rigorous demands of commercial and industrial automation environments.

Advantages

This interface card offers exceptional reliability through its integrated 128-byte FIFO buffer and 16C950 UART compatibility, which effectively prevents data loss during high-speed communication. The inclusion of on-chip hardware auto flow control and built-in ± 2KV ESD protection for all serial signals ensures stable and secure operation. Its Plug-n-Play design simplifies installation, as I/O addresses and IRQ settings are automatically managed by the system BIOS, making it a versatile solution for integrating legacy serial hardware into modern computing setups.

Suitable for

Industrial automation systems
Commercial serial device connectivity
Connecting legacy hardware to modern PCs
Data acquisition and control applications

This card is not suitable for systems that lack a physical PCI expansion slot, such as modern laptops or small form factor PCs that only feature PCIe slots. It is also not intended for high-speed networking tasks that require modern Ethernet or fiber optic interfaces, as it is strictly designed for RS-232 serial communication protocols.

Key specifications

Host interface: PCI
Output interface: 4 x RS-232 serial ports
Data transfer speed: Up to 115.2 Kbps
FIFO buffer: 128 bytes
Bus compatibility: 3.3V and 5V, 32-bit and 64-bit PCI
Operating system support: Windows, Linux, and DOS

How to use

To install the Sunix SER5056A, power down your computer and disconnect it from the power source. Open the computer case and insert the card into an available PCI expansion slot, ensuring it is firmly seated. Once installed, secure the bracket with a screw and close the case. Upon restarting your computer, the operating system should detect the new hardware automatically. Install the appropriate drivers for your specific operating system to enable full functionality of the four serial ports.

What to consider before purchase

Verify that your motherboard has an available physical PCI slot.
Ensure your operating system is compatible with the card drivers.
Confirm that your peripheral devices utilize the RS-232 serial interface.

For optimal performance and to prevent potential data loss, ensure that the card is fully seated in the PCI slot and that the latest drivers provided by the manufacturer are installed for your specific operating system version.
