4. Functionality
The WT13802 functions as a dual-port serial communication interface card for ISA-based computer systems. Each port operates independently, allowing simultaneous communication with two separate RS232 devices. The integrated UART 16550 controller provides hardware buffering, reducing CPU overhead and improving data throughput during high-speed serial communication.
How It Works:
When installed in an ISA slot, the WT13802 interfaces directly with the system bus. The onboard DIP switches allow the user to assign I/O base addresses and IRQ lines to each port, ensuring compatibility with the host system’s resource map. Once configured, the card appears to the operating system as two standard COM ports, enabling seamless integration with serial communication software and drivers.
Use Cases and Applications:
- Industrial automation systems requiring reliable serial communication with PLCs, sensors, or controllers
- Data acquisition systems connecting to measurement instruments or transducers
