### 4. Functionality

The P2016 functions as a multi-port serial communication interface for PCs and servers requiring multiple RS422/RS485 connections. It is ideal for industrial automation, data acquisition, and multi-terminal communication systems.

Operation Principle:
- The P640NU controller manages data flow between the host CPU and external serial devices.
- Each port’s mode (RS422 or RS485) is selectable via DIP switches on the NF216 box.
- The card supports both memory-mapped and I/O-mapped configurations, selectable by BIOS or driver.
- Communication is handled through a DB37 male connector on the card, linked to the NF216 box via the A640 cable.

Typical Applications:
- Industrial control systems and PLC communication
- SCADA and data acquisition networks
- Multi-terminal serial device management
- POS and kiosk systems
- Embedded computing and automation controllers
- Serial device servers and console management

Compatibility:
- Fully compatible with standard PCI slots in desktop, rackmount, and industrial PCs.
- Supports up to two cards per system, allowing expansion to 32 RS422/RS485 ports.

### 6. Installation & Setup

Hardware Installation:
1. Power off the PC and disconnect AC power.
2. Insert the P2016 card into an available PCI slot (3.3V or 5V).
3. Connect the A640 cable from the card’s DB37 connector to the NF216 box.
4. Secure the NF216 box and connect serial devices to its DB9 ports.
5. Configure each port’s mode (RS422 or RS485) using DIP switches.
6. Power on the system and verify BIOS detection.

Software Installation:
- DOS / Windows 95/98/Me: Use I/O map mode drivers.
