Before removing the card from the anti-static protective packaging:
• Discharge any static electricity buildup on your body by touching
a large grounded metal surface or the metal chassis on
equipment connected to earth ground by a 3-wire power cord.
• Avoid touching the gold connectors or other parts on the card
except as necessary to set the configuration jumpers.
• Remove AC power from the computer before inserting the card.
• Retain the ESD bag for handling the card.
CAUTION: ELECTROSTATIC SENSITIVE DEVICE
Use ESD precautions for safe handling.

Chapter 1: General Information
Introduction
The 3PCIO1 Optically Isolated Single Port serial interface card is
designed to work with Windows based IBM compatible computers
equipped with a PCI Bus. The card is Plug and Play compatible
which permits the Windows Operating System and driver to set the
addresses and IRQ used by the card.
If you are developing your own software, make sure that the
communications routines support Windows communication drivers
and a wide range of COM ports (Com1 to Com16 or higher).
Features
• Optically Isolated Multiple Interface PCI Serial Card
• Windows 95/98/2000/XP Compatible Drivers
• Buffered high speed 16C950A UARTs (16C550 compatible) 128
byte FIFOs for input/output with selectable trigger thresholds
• Supports baud rates to 460.8K baud
• Provides 2000 VDC minimum isolation on all lines from the DB9
male connector to the host computer
• Selectable RS-232/RS-422/RS-485 mode
• RS-232 Mode – All eight signals including DCD & RI
• RS-422 Mode – Supports Transmit & Receive signal pairs
• RS-485 Mode – Supports Transmit & Receive signal pairs for
half or full duplex connections.
• 2-wire or 4-wire RS-485 Operation (Half or Full Duplex)
• Automatic Send Data Control for RS-485 Operation
• Com Port Rename – Advanced Driver Function

Chapter 2: Setup
Inspection
Your 3PCIO1 serial card was tested for proper operation before
packaging. It should be in perfect mechanical and electrical condition
upon receipt.
Before removing the card from the anti-static protective packaging:
• Discharge any static electricity buildup on your body by touching
a large grounded metal surface or the metal chassis on
equipment connected to earth ground by a 3-wire power cord.
• Avoid touching the gold connectors or other parts on the card
except as necessary to set the configuration jumpers.
• Remove AC power from the computer before inserting the card.
• Retain the ESD bag for handling the card.
Save the packaging for storage or shipping.
Before Starting…
The card is normally pre-configured for RS-232 operation.
Check/Set 3 Operating Mode Jumpers for Mode desired.
Device Driver Setting for RS-485 Mode:
After driver installation, set DTR Operation to RS-485 Mode.
See Chapter 4,
Setting Driver Options.
