7 CHAPTER 2: Introduction 2. Introduction 2.1 Overview The 8-Port Serial Host Adapter PCI provides the PC with eight RS-232 asynchronous ports. The Adapter allows for connection to any device using the RS-232 electrical interface, such as modems, data-entry terminals, and plotters.
8 8-POR T SERIAL HOST ADAPTER PCI 3. Card Setup 3.1 Clock Modes The Adapter employs a unique clocking option that allows the end user to select from divide-by-4 and divide-by-1 clocking modes. This mode is selected at J1. To select the baud rates commonly associated with COM ports (2400, 4800, 9600, 19.
9 CHAPTER 3: Card Setup 3.2 Baud Rates and Divisors for the “Div1” mode The following table shows some common data rates and the rates you should choose to match them if using the adapter in the “Div1” mode. T able 3-1. Baud Rates for the “Div1” Mode.
10 8-POR T SERIAL HOST ADAPTER PCI 3.3 Address and IRQ selection The Adapter is automatically assigned I/O addresses and IRQs by your motherboard BIOS. Only the I/O address may be modified by the user. Adding or removing other hardware may change the assignment of I/O addresses and IRQs.
11 CHAPTER 4: Installation 4. Installation IMPOR T ANT You MUST set up the operating system BEFORE you physically install the Card. 4.1 Setting Up the Operating System If you are installing the PCI adapter in DOS, OS/2 ® , or QNX, please refer to the appropriate directory on one of the Serial Utilities Disks for instructions.
12 8-POR T SERIAL HOST ADAPTER PCI 4.2 Installing the Hardware You can install the Serial Host Adapter in any of the PCI expansion slots. It contains several jumper straps for each port that you must set for proper operation. 1. Power off the PC. Disconnect the power cord.
13 CHAPTER 5: T echnical Description 5. T echnical Description 5.1 Interrupts A good analogy of a PC interrupt is a telephone ringing. The phone bell is a request for us to stop what we are currently doing and take up another task (speak to the person on the other end of the line).

15 APPENDIX A: T roubleshooting Appendix A: T roubleshooting A.1 Using the Serial Utility Diskettes A Serial Utility diskette comes with the Serial Host Adapter for use in troubleshooting. If you still cannot solve a problem after reading this chapter, call for technical support.
16 8-POR T SERIAL HOST ADAPTER PCI Appendix B: RS-232 Electrical Inter face The most widely used communication standard is RS-232. It’s been defined and revised several times and is sometimes also called EIA/TIA-232.
17 APPENDIX C: Asynchronous Communication Appendix C: Asynchronous Communication In serial data communication, individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character.
18 8-POR T SERIAL HOST ADAPTER PCI An extra bit used for error detection is often appended before the stop bits. This special bit is called the parity bit. Parity is a simple way to determine if a data bit has been lost or corrupted during transmission.
