Chapter 1: GENERAL INFORMATION
Introduction
The B&B Electronics 3PCIOSD2x isolated serial interface card is
designed for IBM compatibles with a PCI Bus. The PCI design is
Plug and Play compatible which allows the driver and Operating
System to select the IRQ and addresses used by the card. This is a
full size card with maximum length and height according to the PCI
Specification 2.1. This card requires a PC that can accommodate
this length.
The 3PCIOSD2x cards offer exceptional setup flexibility with a mix of
selectable operating modes. If you are writing your own
applications, be sure that the communications routine supports
Windows communication drivers and a wide range of COM ports.
Description
The two isolated ports can be independently configured for RS-232,
RS-422, or RS-485 data protocols. The RS-485 mode Automatic
Send Data Control feature transparently handles the enable and
disable functions of the RS-485 transceiver. Buffered, high speed
UARTs (16550 or 16850) make them ideal for high-speed (modem)
and multitasking applications.
Features
IBM compatible, PCI Version 2.1 bus
Supports baud rates to 460.8K baud with 4X clock option
enabled
Provides 2000 VDC minimum isolation on all lines from one DB-
9 male connector to the other and to the host computer
RS-232/422/485 Mode Independently Configurable for Each
Port
High speed 16 byte FIFO 16550A UARTs (Model 3PCIOSD2A),
128 byte FIFO 16850 UARTs (Model 3PCIOSD2B)
RS-485 Automatic Send Data Control or RTS control
2-wire or 4-wire RS-485 operation (half or full duplex)
120 Termination Select Jumpers for RS-422/RS-485 Networks

Chapter 2: SETUP
Inspection
Your 3PCIOSD2x serial card was tested for proper operation before
shipment. It should be in perfect mechanical and electrical condition
upon receipt.
The card is normally pre-configured for RS-232 operation.
The data clock speed for both ports is set by one jumper to x1
(normal) operation or to x4 operation.
The operating mode of each port on the card is set using 8 jumpers,
4 jumpers select RS-232 operation or RS-422/485 operation, one
jumper sets RTS for RS-232 & RS-485 modes or Send Data for RS-
485 mode, 2 jumpers select RS-422 or RS-485 operating modes for
Receive and Transmit, and the last selects 120 ohm termination for
the RS-422 or RS-485 Receiver.
Refer to Jumper Mode Table in Appendix C.
Before removing the card from the anti-static protective packaging:
Discharge any static electricity build-up 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 for each
port. After setting the jumpers, ground yourself to the computer
chassis before and while inserting the card.
Remove AC power from the computer and unplug the power
cord before inserting the card.
Retain the ESD bag for handling the card.
Save the packaging for storage or shipping.
CAUTION: ELECTROSTATIC SENSITIVE DEVICE
Use ESD precautions for safe handling.
