### 4. Functionality

The CI‑132 functions as a dual‑port asynchronous serial communication interface card for PCs. Each port can be configured independently for RS‑422 or RS‑485 operation:

- RS‑422 Mode: Full‑duplex, point‑to‑point or multi‑drop communication up to 10 Mbps over 4000 ft.
- RS‑485 Mode: 2‑wire half‑duplex, multi‑drop communication supporting up to 32 devices per bus.

Automatic Data Direction Control ensures seamless switching between transmit and receive modes in RS‑485 without software intervention. Alternatively, users can select By RTS Mode for backward compatibility with legacy applications.

Use Cases and Applications:
- Industrial and factory automation systems
- Remote serial device control
- Data acquisition and monitoring
- Barcode readers, PLCs, and sensors
- POS systems, scales, and terminals
- SCADA and process control networks

Compatibility:
The CI‑132 is compatible with standard COM port applications and supports Moxa’s PComm and API‑232 libraries for custom software development. It integrates with Windows COMM API and standard serial communication protocols.
