RS-422/485 Universal PCI Multi-port Serial Communication Board

SUNIX RS-422/485 Golden I/O series is a line of Universal PCI Multi-port Serial Communication Board, which attaches DB9 or DB25 RS-422/485 serial ports on your system for industrial communication and automation applications. It is compatible with both 3.3V or 5V and 32-bit or 64-bit PCI Bus, allowing the multi-port serial card to be installed in virtually any available PC system and compatible with all major operating systems. SUNIX RS-422/485 Golden I/O series doesnt require any jumper configuration for setting the I/O address and IRQ location.

RS-422/485 Universal PCI Multi-port Serial Communication Board supports 1/2/4/8 independent RS-422 or RS-485 ports, with each port supporting 128K byte FIFO buffer and are able to control devices in a multi-drop mode. Furthermore, the isolation and surge protection functions can protect your equipment and controller from damaged by lightning or high potential voltage damage, especially in the critical or harsh factory environment.

SUNIX ARSC (Auto RTS Signal Control) technology is the best solution for controlling the half-duplex RS-485 transmission and receiving mode without software or writing extra code. In addition, RS-422/485 auto identify and switch technology allows users the convenience of changing between RS-422 and RS-485 devices without powering down the system for jumpers or switches setting. SUNIX Universal PCI Multi-port Serial Communication Boards are the best solution for all of industrial communication and automation applications.
