### 4. Functionality

The UP2016I functions as an intelligent serial expansion card that offloads communication processing from the host CPU. The P640NU controller manages data flow between the PCI bus and the external serial interfaces, using dedicated UART controllers and onboard memory buffers. Each IF208 box provides eight isolated RS‑422/RS‑485 ports, configurable individually for differential or multi‑drop communication.

Typical Use Cases:
- Industrial automation and process control systems
- Multi‑terminal or multi‑user UNIX/Linux servers
- Data acquisition and instrumentation networks
- SCADA and PLC communication interfaces
- Serial device networking for modems, sensors, and controllers

Compatibility:
- PCI 33 MHz bus (3.3 V/5 V)
- Operating systems: DOS, Windows 95/98/Me/NT/2000/XP/Vista/7, Linux (RedHat, Slackware), SCO OpenServer
- Supports up to two cards per system (32 ports total)

### 6. Installation & Setup

Hardware Installation:
1. Power off the PC and insert the UP2016I card into an available PCI slot (3.3 V or 5 V).
2. Connect the A640 cable from the card’s 37‑pin connector to the first IF208 box.
3. Daisy‑chain the second IF208 box using the provided inter‑box connector.
4. Secure boxes using mounting brackets if multiple units are chained.
5. Power on the system; the PCI BIOS will automatically assign resources.

Software Installation:
- DOS/Windows 95/98/Me: Use I/O‑mapped mode drivers; specify COM port start number during installation.
- Windows NT/2000/XP/Vista/7: Plug‑and‑Play detection; specify driver path (A:\WIN2000). Configure COM port numbering via Device Manager → Multi‑Port Serial Adapter → Setup.
- Linux: Install source‑based driver from /etc/rayon; compile against kernel source (supports kernel 2.2–2.6). Device naming convention: /dev/tty[6–7][1–8][a–h].
- SCO OpenServer: Install via /etc/custom or tar method; rebuild kernel to integrate driver.

Configuration Notes:
- Each port’s RS‑422/RS‑485 mode is set via DIP switch on the IF208 box.
- Ensure only one IRQ is assigned per card; BIOS handles automatic allocation.
- Up to two cards may be installed per system; set JP1 jumper to differentiate first/second card.
