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.

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.

Figure 4. RS-485 Mode Jumper Settings
Explanation of RS-485 Operation
In RS-485 mode the transmit driver must be enabled to transmit, and
set to a high impedance (tri-state) mode at the end of transmission.
In a 2-wire (half duplex) mode, the receiver is disabled during
transmit and enabled when not transmitting.
The 3PCIOSD2x card provides two methods of enabling/disabling
the transmit driver: automatic Send Data (SD) control and Request
To Send (RTS) control. With automatic SD control, the driver is
enabled when data is sent. The driver remains enabled for the
transmission time and ten data bits after data transfer is complete.
The SD circuit automatically adjusts its timing to the baud rate of the
data. With RTS control, software must assert the RTS line to enable
the driver and de-assert to disable the driver. To select SD control
for either port, place the JP2 "Port 1" or "Port 2" jumper in the “Send
Data” (right) position for that port. Place the jumper in the
“RTS(232)” (left) position for RTS control.
The receiver can also be enabled and disabled, a useful feature
in two-wire communications to prevent the transmitted data from
"echoing back" on its own receiver. The second jumper "RX" of JP4
(Port 1) or JP6 (Port 2) determines the receiver mode. If the
jumpers are placed in the “485” position, the "echo" is turned off.
This is achieved by disabling the receiver when the driver is
enabled. Placing the "RX" jumper in the “422” position will hold the
receiver enabled at all times. More information on RS-422
communications can be found in B&B’s free RS-422/485
Application Note (available on our websites).

RS-422 and RS-485 Termination
A 120 termination resistor has been provided for the RS-
422/485 receivers. Note that termination should only be used in
systems with both high baud rates (>19200) and over several
thousand feet of cable. If a value other than 120 is desired, space
for a through-hole resistor has been provided on the board over the
top of the surface mount termination resistor. These through-hole
termination resistors are labeled as RTAB for Port 1 and RTBB for
Port 2, both by its respective connector. See our RS-422/485
Application Note for more discussion on termination (available on
our websites).
RS-485 Network Biasing
Biasing is required on an RS-485 network to hold the network in the
marking state between transmissions. The 3PCIOSD2x RS-485
receiver is biased with a 4.7 K pull-up surface mount resistor on
the Receive Data B line and a 4.7 K pull-down surface mount
resistor on the Receive Data A line. These values are usually
adequate for networks without termination and small numbers of
nodes. For more complex networks, the user must calculate the
required value and replace these resistors. Space for through-hole
resistors has been provided over the top of the surface mount
components placed at the factory. The through-hole resistor for the
pull-up is marked as R5B and the pull-down is marked as R13B for
Port 1. Similarly, the pull-up is marked as R30B and the pull-down is
marked as R36B for Port 2.
4X Baud Rate Option
Baud rates higher than 115,200 are possible with the 3PCIOSD2x
card in RS-232, 422, or 485 mode. Jumper JP1 controls the clock
frequency (for both ports) supplied to the UARTs. By moving this
jumper to the “*4” (left) position, the clock frequency is increased
from 1.8432 to 7.3728 MHz. This multiplies all UART baud rates by
4 times. For example, if the software is set for 57.6K baud, the
actual baud rate will be increased by a factor of four to 230.4K baud.
In many systems, these higher baud rates can improve throughput
significantly. However, remember that baud rates and actual
throughput are only proportional if the system can keep up with the
communications, otherwise increasing the baud rate effectively only
increases the idle time between characters.

Chapter 3: WINDOWS INSTALLATION
Windows 95 and Windows 98
Any prior installation using previous B&B Serial drivers must be
removed before installing the new drivers. (Refer to page 23.)
Windows 98 screens are shown for this section. Windows 95 is a bit
different with fewer steps and the screen names and text shown
differs. Windows 95 differences are noted (W95:…)
1. Configure each port on the PCI card to the desired RS-
232/422/485 mode using the jumpers.
2. Install the card in the slot, start the computer.
3. Windows will detect the PCI card, start the Add New Hardware
Wizard, and begin driver installation. When installation is
complete, Windows will set the hardware addressing & interrupt
using the drivers and the Plug and Play function of the
Operating System.
4. The driver installation proceeds in two parts: the first part installs
the driver for the PCI Serial card and the second part installs the
serial driver for the Com Port A & B (Port A=Port 1, Port B=2).
NOTE: The Optically Isolated 3PCIOSD2x PCI Serial Adapter card
will be identified as the 2-Port PCI Serial Adapter (3PCISD2). Both
cards use the same drivers and are functionally the same to the
Operating System.
