### 2. Key Features

- High-Density Serial Expansion:
Provides 16 serial ports per PCIe card, configurable as 8 RS422/485 and 8 RS232/422/485 interfaces.
Supports expansion up to 64 ports per system using multiple connector boxes.

- Ground Isolation:
Each port is electrically isolated to prevent ground loops and protect connected devices from voltage surges and noise interference.

- Intelligent Processor Architecture:
Built on the A320 intelligent multiport controller, featuring a local processor and dedicated memory map for efficient data handling and reduced CPU load.

- Flexible Interface Configuration:
Each port can be individually configured via DIP switches for RS232, RS422, or RS485 operation, supporting both point-to-point and multi-drop communication.

- Single IRQ Resource Management:
Utilizes one IRQ for all ports, optimizing system resource allocation and simplifying driver configuration.

- Broad OS Compatibility:
Supports a wide range of operating systems including DOS, Windows 95/98/Me/NT/2000/XP/Vista/7, Linux, and SCO OpenServer.

- High-Speed Communication:
Each port supports baud rates from 110 to 115,200 bps, with both software (XON/XOFF) and hardware (RTS/CTS) flow control.

- Industrial Reliability:
Designed for continuous operation in industrial environments with wide temperature and humidity tolerance.

- Plug-and-Play PCIe Interface:
Fully compliant with PCI Express 3.3V and 5V 33MHz slots, supporting automatic resource assignment by the PCI BIOS.
