Page 6: Chapter 1: Introduction
Chapter 1: Introduction The PCI Express Multiport Serial cards were designed for RS232, RS422 and RS485 asynchronous communications for use in a variety of applications. These boards were designed to offer compatibility with the PCI Express bus and to be used by system integrators and manufacturers in the design of industrial and commercial communication systems. -
Page 7: Functional Description
Functional Description These cards feature high performance 16C950 class UARTs which support the complete register set of the standard 16C550-type devices. The UARTs support operations in 16C450, 16C550 and 16C950 modes. Each port is capable of data communication speeds up to 3Mbps (standard model up to 460.8kbps in RS-232 mode) in asynchronous mode and has 128-byte deep transmit and receive FIFOs to protect against lost data in multitasking operating systems, to help reduce CPU utilization and to improve data throughput. -

Page 9: Special Order
Special Order Virtually any custom baud rate can be achieved with the standard card (see Table 5-2: Higher Baud Rate Register Settings) and still be within the standard tolerance range for serial communications. If that method doesn‟t produce an exact enough baud rate a custom crystal oscillator may be specified, contact factory with your precise requirement. -
Page 10: Chapter 2: Installation
Chapter 2: Installation A printed Quick-Start Guide (QSG) is packed with the card for your convenience. If you‟ve already performed the steps from the QSG, you may find this chapter to be redundant and may skip forward to begin developing your application. The software is provided with this card on the CD and must be installed onto your hard disk prior to use. -
Page 11: Hardware Installation
Hardware Installation Caution! * ESD A single static discharge can damage your card and cause premature failure! Please follow all reasonable precautions to prevent a static discharge such as grounding yourself by touching any grounded surface prior to touching the card. 1. -
Page 12: Chapter 3: Hardware Details
Chapter 3: Hardware Details There only user-selectable options for this card are for applying a termination load to the RS- 485 lines. Channel protocols are selected via software. Figure 3-1: Option Selection Map Factory Option Descriptions Fast RS-232 transceivers (-F) The standard RS-232 transceivers used are capable of speeds up to 460.8kbps which is adequate in many applications. -
Page 13: Remote Wake-Up (-W)
Remote Wake-Up (-W) The “Remote Wake-Up” factory option is for use in applications where the host computer (the one this card would be installed in) enters the L2 low-power state where it‟s main power is turned off though VAUX is still applied. When the Ring Indicator is received on serial port channel A in the L2 power state, Wake-Up is asserted. -
Page 14: Chapter 4: Address Selection
Chapter 4: Address Selection The card uses one I/O address space PCI BAR[0]. COM A, COM B, COM C, COM D, COM E, COM F, COM G and COM H each occupy eight consecutive register locations. These COM designations correlate to the corresponding DB9 on breakout cable, which are labeled as such. -
Page 15: Chapter 5: Programming
Chapter 5: Programming Sample Programs There are sample programs with source-code provided with the card in a variety of common languages. DOS samples are located in the DOS directory and Windows samples are located in the WIN32 directory. Windows COM Utility Program WinRisc is a COM utility program provided on CD with the installation package for this card that is very useful when working with any serial ports and serial devices. - Page 16 To ensure the proper operation of the Baud Rate Generator, users should avoid setting the value „0‟ to Sample Clock, Divisor and Prescaler. The following table lists some of the commonly used Baud Rates and the register settings that generate a specific Baud Rate. The examples assume an Input Clock frequency of 14.7456 Mhz.

Page 17: Chapter 6: Connector Pin Assignments
Chapter 6: Connector Pin Assignments Input/Output Connections The serial communications ports are interfaced at the card mounting bracket via a female 68- pin VHDCI D-connector. There are two different breakout cables available terminating in eight (or four) individual D-sub 9-pin connectors. These cables are permanently labeled near each DB9 connector with the port letter. -
