### 4. Functionality

The Xtreme/104 Opto functions as a high-speed serial interface module for embedded PC/104 systems. It connects the host computer to multiple external serial devices such as barcode scanners, industrial sensors, PLCs, scales, and time clocks. Each port can be configured independently for RS-232 or RS-422/485 operation, supporting both point-to-point and multi-drop network topologies.

Operational Modes:
- Full Duplex: Continuous bidirectional communication (typical for RS-232 or RS-422 point-to-point).
- Half Duplex: Transmit and receive share the same pair; automatic RTS control manages direction.
- Multi-drop Slave: Enables communication with multiple devices on a shared bus.

Compatibility:
- Works with standard serial communication software and drivers.
- Supports operating systems: DOS, Linux, QNX 4/6, SCO Unix, Solaris, Windows 95/98/Me/CE/CE.NET/NT/2000/XP.

Applications:
- Industrial automation and control systems
- Data acquisition and monitoring
- Machine-to-machine (M2M) communication
- Embedded instrumentation
- Transportation and logistics systems
