### 4. Functionality

The CP‑132IS provides two asynchronous serial communication channels that can be configured individually for RS‑422 or RS‑485 operation. Each port supports either:

- RS‑422 Full‑Duplex: Point‑to‑point or broadcast communication up to 10 Mbps over distances up to 4000 ft (1200 m).
- RS‑485 Half‑Duplex: Multi‑drop communication supporting up to 32 devices per port.

Automatic Data Direction Control (ADDC) hardware manages transmit/receive switching in RS‑485 mode, allowing transparent half‑duplex communication without software intervention. Alternatively, users can select By RTS Mode for legacy applications that manually toggle RTS.

Use Cases and Applications:
- Industrial automation and process control systems
- Factory data acquisition and SCADA networks
- Remote serial device management
- Multi‑point sensor or actuator networks
- Industrial PC integration for RS‑422/485 instrumentation

Compatibility:
The CP‑132IS is compatible with standard PCI slots in desktop or industrial PCs. It supports Windows NT/95/98 and DOS environments, with Moxa drivers conforming to the Win32 COMM API. The board can coexist with other PCI devices, provided unique IRQ and I/O resources are available.
