Introduction
Thank you for purchasing a StarTech.com 16950 PCI Serial card. The latest in Plug and Play
expansion cards, this high-speed serial card provides your computer with two, four, or eight
16C950 UART (Universal Asynchronous Receiver-Transmitter) RS-232 serial ports (varies by
model). You can connect any 9-pin external serial device such as a modem, mouse, or ISDN
adapter to your system and enjoy speeds of up to 15 Mbits/sec (asynchronous mode) or 60
Mbits/sec (isochronous) mode. This 32-bit, 33MHz PCI card is also backwards compatible with
UART versions to ensure compatibility with a wide range of serial peripherals.
Features
• Provides two/four/eight 16C950 UART RS-232 serial ports
• Buers up to 128 bytes for FIFO receiving/transmitting
• Fully adjustable IRQ trigger levels
• Automated ow-control to prevent UART overrun
• Backward compatible with 16C450, 16C550, 16C650, and 16C750 UARTs
• Complies with PCI Bus specication 2.2, Power Management 1.0, and Plug and Play
specications
• Backed by StarTech.com’s lifetime warranty
Before You Begin
To ensure a quick and easy card installation, please read through this section carefully before
attempting to install the card.
System Requirements
• An IBM PC running Windows 95/ 98SE/ ME/ 2000/ XP(32/64bit)/ Vista(32/64bit)/ 7(32/64bit)/
Server 2008 R2, and Linux
• An available PCI slot
• A CD-ROM or other compatible optical drive (for driver installation)
WARNING! PCI cards, like all computer equipment, can be severely damaged by static electricity.
Be sure that you are properly grounded before opening your computer case or touching your PCI
card. StarTech.com recommends that you wear an anti-static strap when installing any computer
component. If an anti-static strap is unavailable, discharge yourself of any static electricity buildup by touching a large grounded metal surface (such as the computer case) for several seconds.
Also be careful to handle the PCI card by its edges and not the gold connectors.

Installation
This section will guide you through the installation of your PCI card and the related software.
Please read through the instructions carefully and complete each step in the order listed.
Installing the Card
NOTE: Advanced computer users may wish to change the clock options on the card. Please see
“Advanced Per formance Conguration” on page 4 before installing the card.
1. Make sure that your system is unplugged and you are grounded.
2. Remove the cover of your system (see your computer’s user manual for details, if necessary)
and gently turn your computer onto its side.
3. Locate an empty PCI slot (usually white in color) and remove the metal plate that covers the
rear bracket. You may need a Phillips screwdriver to perform this step. Retain this screw! You
will need it to secure the card later.
4. Gently insert the card into the empty slot, making sure it is rmly seated.
5. a) Secure the card in place using the screw you removed in Step 3.
b) If you purchased a PCI8S950 (8 port model), connect the ribbon cable panel for the second
dongle connector to the pins on the card, with the red stripe on the ribbon cable facing Pin 1
(as marked). Remove the screw and metal plate on another available slot. Secure the second
dongle connector in place with the screw.
c)If you purchased a PCI4S950 (4 port model) or PCI8S950 (8 port model), connect the port
dongle(s) provided to the port on the back of the card (and the additional dongle connector
you installed, if applicable).
6. Put your computer case back on.

Advanced Performance
Conguration (PCI2S950 only)
As an option, you can choose to congure the clock frequency of your card by setting the
JP15 jumper pins. You can alter this setting by placing the jumper on the pins according to the
following chart:
Pins Setting
3-2 1.843 MHz
2-1 40.0 MHz (OSC)
As a third option, you can choose to replace the 40.0 MHz oscillating (OSC) crystal with an OSC
crystal with a frequency that satises your needs.
WARNING: The following instructions are intended for advanced computer users only. If you are
not comfortable with or knowledgeable about internal computer parts, please do not attempt
to congure your card in this manner. Be sure to consult the charts on the following page before
adjusting your card.
1. Remove the plastic fastener from the OSC crystal (located immediately above and to the right
of JP15) and gently lift the crystal from the crystal socket.
2. Install the replacement OSC crystal according to the manufacturer’s instructions. If you attach
the crystal incorrectly you can damage it. Be sure to attach the crystal properly to avoid
damaging the card or other components.
3. You may need to adjust the FIFO and Crystal (or Data Rate) settings for the ports. Consult
your operating system’s documentation for more information.
