Chapter 1: GENERAL INFORMATION Introduction The B&B Electronics 232PCI1A, 232PCI1B, 232PCI2A and 232PCI2B serial interface cards are 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. If you are writing your own applications, be sure the communications routine used supports Windows communication drivers and a wide range of COM ports.
Specifications Bus: PCI bus version 2.1 Slot: Requires one PCI slot Dimensions: 6.2 x 4.2 in (15.8 x10.7 cm) I/O Connections: 9 pin male D-sub (DB9M) connectors OS Supported: Windows 95, 98, 2000, and NT 4.0 Baud rates: 460.8K baud maximum UARTs: 16550A 16 byte TX and RX buffers (232PCI1/2A), or 16850 128 byte TX and RX buffers (232PCI1/2B) Character length: 5, 6, 7, or 8 bits Parity: Even, odd or none Stop bits: 1, 1.

Chapter 2: SETUP Inspection Your 232PCIxx serial card was tested for proper operation before shipment. It should be in perfect mechanical and electrical condition upon receipt. The data clock speed is set by one jumper to x1 (normal) operation or to x4 operation. Dual port cards share the single master clock. CAUTION: ELECTROSTATIC SENSITIVE DEVICE Use ESD precautions for safe handling. Before removing the card from the anti-static protective packaging.

4X Baud Rate Option Baud rates higher than 115,200 are possible with the 232PCIxx card. Jumper JP1 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 57.6K baud, the actual baud rate will be increased by a factor of four to 230.4K baud.

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 1 or 2-Port 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 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. Computer RS-232 ports are always configured as DTE (Data Terminal Equipment) devices. Some devices (such as printers, video recorders/editors, cameras) are also configured as DTE.

Appendix C: 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, 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.
Appendix D: Renaming COM Ports - Win 95/98/ME 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.
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.
(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.
