•RS-485 Signal Lines: TD(A), TD(B), RD(A), RD(B) and Signal
Ground. (Data A & Data B lines when wired for 2-wire
operation.)
The B&B Electronics 3PCISD4x 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 hardware addresses used by the card.
The 3PCISD4x card offers exceptional setup flexibility with a mix
of selectable operating modes. If you are writing your own
applications, be sure the communications routine used supports
Windows communication drivers and a wide range of COM ports.
Description
Each of the four ports can be independently configured for RS232, RS-422, or RS-485 data protocols. The 485-mode Send Data
Control feature transparently handles the enable and disable
functions of the RS-485 transceiver. Buffered, high speed UARTs
(16550A or 16850) make it ideal for high speed (modem) and
multitasking applications.

Your 3PCISD4x 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 on all
ports.
The data clock speed for all 4 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 9 jumpers:
5 jumpers select RS-232 operation or RS-422/485 operation, 2
select RS-422 or RS-485 operating modes for Receive and
Transmit, one sets the RS-485 mode driver control for Send Data or
RTS control, and the last selects 120 ohm termination for the RS422 or RS-485 Receive. Each of the 4 ports is configured in a
similar fashion.
Refer to Jumper Mode Tables,Appendix B.
CAUTION: ELECTROSTATIC SE NSITIVE DEVICE
Use ESD precautions for safe handling.
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 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.

With 2-wire RS-485 mode operation, your connection cable
must jumper RD(A) to TD(A) and RD(B) to TD(B). Connect from
TD(A) & TD(B) to the Data A(−) and Data B(+) wires of your RS-485
network.
The EIA RS-422 Specification labels data lines with an "A" and
"B" designator. Some RS-422 equipment uses a "−" and "+"
designator. In almost all cases, the "A" line is the equivalent of the
"−" line and the "B" line is the equivalent of the "+" line. More
information on RS-422 communications can be found in our free RS422/485 Application Note (available on our websites).
RS-485 Mode
For a 4-wire RS-485 single master system, the card can be set as in
the RS-422 mode (full duplex, transmit & receive enabled).
Nine jumpers must be set/checked to configure each Port to the RS485 mode. To set Port 1 for RS-485, set as follows below:
1. Set the four jumpers on JP1 to the "422" (right) position.
2. Set the top jumper of JP3 (A) to the "422/485" (right) position.
3. For 2-wire mode, set the second jumper, JP3(B) to the "485"
(left) position (half duplex). For 4-wire mode, set it to the "422"
(right) position (full duplex, receive enabled).
4. Set the third jumper, JP3 (C) to the "485" (left) position.

5. Set the fourth jumper of JP3 (D) to select the type of RS-485
transmit driver control, RTS or Send Data. Select SD control
unless you are sure your software requires RTS control.
6. The bottom jumper of JP3 (E) switches the 120Ω receiver
termination resistor in or out. Typically this resistor is not used.
In some cases using high baud rates and very long cables,
termination is needed. See our RS-422/485 Application Note(available on our websites).
7. Configure each port as above using the table in Appendix B.
RS-485 Pinouts
The pinouts in RS-485 mode are the same as those listed in Table 8
for RS-422 mode.
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 two wire (half duplex) mode, the receiver is
disabled during transmit, and enabled when not transmitting.
The 3PCISD4 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 transmit 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 disassert to disable the driver. To select SD control
for Port 1, place the fourth jumper of JP3 (D) in the SD (right)
position. Place this jumper in the RTS (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 on JP3 (B)
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 transmit driver is enabled. Placing this jumper in
the 422 position will hold the receiver enabled at all times.
Refer to the Jumper Mode Table in Appendix B for all ports. More
information on RS-485 communications can be found in our RS422/485 Application Note (available on our websites).
Documentation Number 3PCISD4x-3903 Manual Chapter 2 9
B&B Electronics Mfg Co – 707 Dayton Rd - PO Box 1040 - Ottawa IL 61350 - Ph 815-433-5100 - Fax 815-433-5104
An 120Ω 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 120Ω is desired, space for a through
hole resistor has been provided on the board adjacent to the surface
mount termination resistor. The termination resistors are labeled
RTAB, RTBB, RTCB and RTDB for ports 1, 2, 3 and 4 respectively.
See our RS-422/485 Application Note for more discussion on
termination (available on our websites).
4X Baud Rate Option
Baud rates higher than 115,200 are possible with the 3PCISD4x
card in RS-232, 422, or 485 mode. Jumper JP5 controls the clock
frequency 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 57.6 Kbaud, the actual baud rate
will be increased by a factor of four to 230.4 Kbaud. 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.

If you have any trouble starting your system after installing the card,
the card may not be properly seated in the slot. Remove and reinsert it or try a different slot.
If you are unable to communicate with the card using your software
and hardware devices:
1. Check your pinouts. In RS-422 or RS-485 mode the "A" lines
should match your "A" or "−" lines. "B" lines should match your
"B" or "+" lines. Note: RS-422/485 pinouts are non-standard.
2. Use the COMTest program provided on the PCI/USB Port Utility
Disk with a loop back to check the card. Run Setup.exe to install
COMTest on your program menu under B&B Electronics.
A Loopback connection for RS-232 connects the Transmit
output to the Receive input. (pins #2 & #3 on the DB9
connector) For RS-422 or 4-wire RS-485, connect the TD(A) to
RD(A) and the TD(B) to RD(B). Then use the COMTest program
to send characters, and observe the characters being received.
To check 2-wire RS-485, you will need to enable the receiver by
moving the receive jumper to 422 mode, or use one Port to
transmit to another by cross connecting and loading COMTest
twice, one copy for each port. Characters typed in one copy of
COMTest will appear in the receive window of the other. Note
that software must ignore the RS-232 handshaking lines in RS422/RS-485 mode, the input lines (CTS, DSR, DCD, RI) are not
pulled high.

With 2-wire RS-485 mode operation, your connection cable must
jumper RD(A) to TD(A) and RD(B) to TD(B). Connect from TD(A) &
TD(B) to the Data A(−) and Data B(+) wires of your RS-485 network.
The EIA RS-422 Specification labels data lines with an "A" and "B"
designator. Some RS-422 equipment uses a "−" and "+" designator.
In almost all cases, the "A" line is the equivalent of the "−" line and
the "B" line is the equivalent of the "+" line. See our RS-422/485
Application Note (available on our websites).

Renaming PCI COM Ports Using the PnP COM Rename Utility
CAUTION: You must be using Windows 95/98 or ME. This utility is
not designed for NT or other Windows versions.
This program edits the registry directly, it will only change entries
related to B&B PCI or USB Serial Ports. Improper use of this
program can cause conflicts with other COM Ports installed on your
computer.
Renaming COM ports will only affect software that accesses COM
ports through Windows, not software that accesses ports from DOS
or at the hardware level.
This program should only be used after all serial ports have been
installed.
Windows 95/98 and ME automatically assigns COM port numbers
starting at COM5 when the port is not at the standard base
addresses for COM1 to COM4.
If your software refuses to access COM ports above COM4, and you
have unused COM numbers that you want to be able use with your
B&B PCI Serial Card, this utility can be used to rename some or all
of the ports to the unused COM numbers.
First, check the ports list shown in the Device Manager, then check
any Modem or FAX device to make sure that the port number isn't
being used for a FAX/Modem or Network Redirector.
If you have built-in ports you want to disable from the BIOS in order
to use your PCI card at that COM number, first remove the port with
the Device Manager. Then re-boot to the BIOS, disable the port with
hardware settings, Exit with a "Save Settings", then re-start
Windows Next, verify the port number is not present. Then use the
Rename utility to rename the PCI card ports as needed.
To Remove a Port: Choose Settings, Control Panel, System, Device
Manager, then select the port to highlight it. Click Remove below the
window. To remove all B&B PCI ports, select the B&B Serial
Adapter. This clears registry entries for the card and ports.
Install the PCI/USB COM Port Utilities
(1) To use the PnP COM Rename utility, insert the PCI/USB COM
Port Utility Disk and run Setup.exe. This will install COMTest
and PnP COM Rename under Programs, B&B Electronics.
(2) The Rename utility will not be installed if you are running
Windows 2000 or NT.
Using PnP COM Rename
(1) Shut down all programs that are accessing any Com ports.
(2) Start the PnP COM Rename Utility from the Programs menu
under B&B Electronics.
(3) Read the Cautionary Warnings, it is possible to rename a PCI or
USB serial port to a number already in use which will cause
problems. If any problems occur after renaming, you may need
to re-start the system and rerun the Rename utility to correct the
situation or remove the serial card in the Device Manager. Then
Refresh the Device Manager to detect the card and re-install the
drivers. Determine which renamed COM port caused the
problem, and do not use that name for a renamed port.
(4) Accept the conditions of use by clicking Yes or click No to exit.
(5) Select the currently named COM port number you want to
change in the left window, then the new number in the right
window. Then click Finish. Repeat for other ports as needed.

(6) If the PCI card was previously installed and not removed in the
Device Manager, you may find several B&B COM ports with the
same number. The last instance of the same number is usually
the most recent installation. Only the active ports can be
renamed with the program to show the new name under the
Device Manager. Inactive port numbers will not show any
change after renaming. Ideally, unused entries should be
removed by using RegEdit, then having the system re-install the
drivers to make the entries. This will result in a single entry for
each port on the card, and only that entry will need to be
changed.
(7) After all B&B PCI or USB COM ports have been renumbered as
needed, click Close to exit.
If you need to install another serial device after using renaming with
this utility, you must:
(1) Name all COM Ports back to original settings using this
program.
(2) Install the new device according to manufacturer directions.
(3) Use this utility to rename the B&B COM Ports again as needed.
