Description

The SUNIX IPC-E3204S is an industrial 4-port PCI Express serial communication card designed to expand a compatible PC with four independent RS-232, RS-422 or RS-485 serial ports. It is intended for applications where multiple serial devices need to communicate with a single computer, including industrial automation, control systems, data acquisition and integration of serial equipment.

Each serial port supports data rates from 50 bps up to 921.6 Kbps. The card incorporates the SUNIX SUN2410 controller, which is 16C950 UART compatible, together with a 128-byte hardware FIFO. This hardware buffering helps support reliable high-speed serial input and output while reducing the risk of data loss during communication.

The IPC-E3204S supports RS-422 and RS-485 automatic detection and switching, allowing different supported serial interfaces to be selected without jumpers. SUNIX AHDC technology provides RS-485 signal direction control, while hardware auto flow control is designed to help maintain reliable data communication.

Protection is an important part of the card design. The serial signals have up to 15KV ESD protection for air discharge and 8KV ESD protection for contact discharge. RS-422 and RS-485 signals also have 1KV surge protection. The card uses a PCI Express 2.0 x1 interface and is supplied with standard and low-profile bracket options for flexible installation in compatible computer systems.
