description

Sunix developed RS-422/485 Serial Board with PCI-Express interface for your industrial communication and automation applications. PCI Express architecture is a cost-effective, low-pin count interface offering maximum bandwidth per pin, reducing cost and design complexity and enabling smaller form factors.

The 8439 card works on one-lane 2.5 Gbps PCI-Express compliant specification. The card supports multi independent RS-422 or RS-485 ports, with each port transfer data up to 921.6 Kbps and able to control device in a multi-drop mode. Furthermore, Isolation and Surge protection (optional) can protect your equipment and controller from being damaged by static electrical charge and high energy spike. Sunix ARSC (Auto RTS Signal Control) technology provides the best way to make half-duplex RS-485 auto data transmission and receiving without software or writing extra code. In addition, Sunix RS-422/485 Auto Identify & Switch technology allows users the convenience of changing between RS-422 and RS-485 devices without jumper or switch setting. Sunix PCI-Express Multiport Serial Board is the ideal solution for various industrial communication and automation applications.
