Introduction

SUNIX IPC-P2104SI, industrial standard universal PCI serial communication card, allows users to expand four RS-422/485 ports on PC-based system. Each serial port achieves data rates up to 921.6 Kbps and utilizes 16C950 UART with an on-chip 128-bytes hardware FIFO buffer for reliable, high-speed serial I/O. With SUNIX patented Auto-Switching RS-422/485 and RS-485 AHDC™ technology, user can easily manage different serial interfaces selection and RS-485 signal direction control. Under RS-485 mode, the board can connect up to 31 daisy-chained RS-485 devices within a range of 1.2 km.

SUNIX IPC-P2104SI uses on-board 2500V optical isolators which achieve on power and serial signal lines to protect your PC and equipment against damages from ground loops, increasing system reliability in harsh environments. To further increase reliability, this board offers 500W surge protection technology, protecting your system from abrupt high voltage surges, such as those caused by lightning. SUNIX serial board supports a wide variety of operating systems, including Windows, Linux, DOS, and UNIX. It is the best serial communicating solution for industrial and harsh environment applications.
