4. Functionality
The A320 functions as an intelligent serial expansion controller. Installed in a PCIe slot, it communicates with the host system through memory or I/O mapping. The onboard processor manages data flow between the host CPU and external serial interfaces, significantly reducing CPU load.
Each A320 card connects to one or more external connector boxes via a DB37 cable. These boxes (NF or IF series) provide the physical serial ports and determine the electrical interface type. The system can be expanded by daisy-chaining up to eight boxes, each providing 8 or 16 ports, to achieve a total of 64 ports per card.
Use Cases:
- Industrial automation and control systems requiring multiple serial connections.
- Data acquisition systems with mixed RS232/RS422/RS485 devices.
