| | | |  | 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 8459 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 ARSCTM (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. | | |  |  | Low RMA rate and high reliability with Sunix's single chipset designed ASIC | | Compliant with one-lane 2.5 Gbps PCI-Express specification | | Industrial grade design for stability and reliability | | Built-in termination resistors to avoid cross-talking | | 128K FIFO buffer can reduce CPU loading, less interruption and improving system performance dramatically | | RS-422/485 Auto Identify and Switch technology enable device plug-n-play without jumper or switch setting | | ARSCTM (Auto RTS Signal Control) technology allows accurate switching of the transmitter on and off for precise timing of the data transmission | | Optical isolation (2.5KV) provides protection against damage from static electrical charge | | Surge protection (600W) provides protection against surge damage from high energy spike | | RS-422/485 Handshaking Communication provides hardware flow control for best prevention of data error or data lost | | Plug-n-Play, I/O address and IRQ assigned by BIOS | | RS-422/485 industrial host controller series are certified by WHQL, CE, FCC approval | | Support Microsoft Windows, Linux, and DOS |
