• Chapter 1: GENERAL INFORMATION Introduction The B&B Electronics 3PCIOSD1x single port 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. The 3PCIOSD1x cards offer exceptional setup flexibility with a mix of selectable operating modes.

Chapter 2: SETUP Inspection Your 3PCIOSD1x 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 is set by one jumper to x1 (normal) operation or to x4 operation.
PAGE 6
RS-232 Mode RS-422 Mode To configure the port for RS-232 mode, 5 jumpers must be set/checked. The following settings will configure the port as RS232: To configure the port for RS-422 mode, 7 jumpers must be set/checked. The following settings configure the port as RS-422: 1. Set four jumpers of JP2 (A-D) to the "232" (left) position. 1. Set the four jumpers of JP2 (A-D) to the "422/485" (right) position. 2. Set JP1 to the "RTS(232)" (right) position. 2.
PAGE 7
5. The bottom jumper "Termination" of JP4 switches the 120 Ω 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 B&B’s free RS-422/485 Application Note, Termination section, page 16, for more information (available on our websites). RS-422 Pinouts The RS-422 mode supports 2 channels (transmit and receive).
PAGE 8
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 determines the receiver mode. When 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.

Chapter 3: WINDOWS INSTALLATION 5. After new hardware is detected, this screen will appear. (W95: This screen is named Update Device Driver Wizard). 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 20.) 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.

You can check details of the serial card setup using Windows NT Diagnostics, found under Administrative Tools. This can show the Resources used such as addresses and IRQ. Windows Diagnostics will not allow changing anything. 12. Verify 1 new COM Port. (shown here as COM5) If you have 1 new COM port, the installation is complete. Select the port, select Settings, Advanced. You should obtain the message, "There are no user configurable Advanced I/O parameters for this COM port.
PAGE 18
The screen below shows the address range for the serial port on the B&B Electronics 1-port Serial Card. Removal of Card and Driver If you need to remove the card from your system or remove the current driver before installing a possible future driver upgrade: 1. Open the Windows NT subdirectory. 2. Open System32. 3. Open Drivers. 4. Find the "Bbserial.Sys" file and delete it. 5. Shut down the system. 6. Remove the Optically Isolated PCI Serial Adapter card.

Chapter 4: TROUBLESHOOTING If you have any trouble starting your system after installing the card, the card may not be properly seated in the slot. Remove and re-insert 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.

Appendix D: TROUBLESHOOTING WITH COMTest Included on the PCI/USB COM Port Utility Disk is a test program called COMTest. It can be installed on your “Programs” menu for use by inserting the disk and running Setup. COMTest is a simple 32-bit Windows (Windows 95, 98, 2000 or NT) COM port Test program. It is a simple tool that can be used to troubleshoot RS-232, RS-422, or RS-485 serial communications. It allows multiple ports, at any address and IRQ, to be opened at any given time.
PAGE 24
Appendix E: ISOLATION AND GROUND The 3PCIOSD1x provides 2000 VDC minimum isolation on all lines from the DB25 connector to the host computer. The 3PCIOSD1x cards have no connection from pin 1 (chassis ground) to ground of the host computer. This was done to completely isolate the computer end of the communications. In most applications, the shield wire should be connected to ground on only one end of the network. Board space is provided to connect pin 1 to the isolated port ground (pin 7).

Appendix F: Renaming COM Ports - Win 95/98/ME Install the PCI/USB COM Port Utilities Renaming PCI COM Ports Using the PnP COM Rename Utility (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. CAUTION: You must be using Windows 95/98 or ME. This utility is not designed for NT or other Windows versions.
PAGE 26
(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.
