VMIC VMICPCI7755 | PCI Serial Communication Board

Industrial Communication Solutions

Main Features and Benefits

The VMIC PCI7755 delivers robust industrial communication in harsh environments through its uniquely flexible quad-port architecture. Each port features software-configurable RS-232/422/485 capabilities, eliminating the need for physical jumpers or daughterboards during protocol changes. The board’s advanced ASIC controller provides true 16C950 UART functionality with 128-byte FIFO buffers that prevent data loss during high-speed transfers up to 921.6 Kbps.

Critical operational advantages include:

• Advanced signal protection: 2500V optical isolation and 15kV ESD protection per IEEE 485 specifications
• Intelligent data flow: Automatic RS-485 bus control eliminates external converters
• Terminal flexibility: DB9 connectors support direct connection to field devices

For reliability in electrically noisy industrial settings, the PCI7755 implements galvanic isolation between all serial ports and the host computer system. The board maintains consistent performance across extreme temperature fluctuations and provides electrostatic discharge protection significantly exceeding industry standards. Legacy system integration becomes seamless through comprehensive driver support for real-time operating systems including VxWorks and QNX.
