Before You Begin your Installation
This installation manual contains detailed
instructions for the installation of your product.
We recommend reading and following these
instructions thoroughly first. If you require
technical assistance, Boca Research has a number
of available options as described below.
How to get Technical Assistance
The dealer that you purchased this product or your computer from is
the first place you should go for technical assistance. The dealer is
usually the most qualified source of help, and is most familiar with
your system and how this product should be installed. Many dealers
have customer service and technical support programs, with varying
levels of support offered, depending on your needs and computer
knowledge. Please contact the dealer first whenever a problem
occurs. International customers will find that contacting the place of
purchase for assistance will be much more efficient than contacting
Boca Research directly.
If your Dealer Can’t Assist you
If you can’t get assistance from your dealer, the manufacturer
provides varying levels of technical assistance as summarized below.
All phone numbers are based in the United States.

2. What is a Modem
2. What is a Modem?
A modem is a device that allows computers to communicate
with each other over normal telephone lines.
You may know that computers process information in the form
of digital electronic signals. Because telephone lines are
designed to carry voice or sound, a modem is required to
convert the digital signals of the computer to sound signals.
Another modem is required to convert the sound signals back
to digital signals at the other end.
Hi Mike,

The word “modem” is an abbreviation of the words
“Modulator/Demodulator”. Modulation describes the process
of converting the digital signal to a sound signal; demodulation
is the reverse process.
Boca Research, Inc. is an award winning developer of
communications products and markets a range of modems that
span low-cost, general purpose modems for home and
education use, competitively priced models for small and
medium sized businesses as well as advanced, high-speed,

4. Before Connecting Your PRO16SA
Communications (COM) Ports
• Your PRO16SAmust communicate with your computer
through a serial port, also known as a COM port
• You must know the number of COM ports that already exist
so that you can configure your modem correctly
The COM ports in your machine are controlled by two
settings:
1. Address which tells your computer at what hexadecimal
location your COM port exists.
2. IRQ (known as the interrupt) which is a signal the computer
uses to communicate with the installed hardware.
Following are the typical configurations for COM ports:

13
4. Before Connecting the PRO16SA
COM PORTS ADDRESS IRQ (interrupt)
COM 1 3F8H 4
COM 2 2F8H 3
COM 3 3E8H 4
COM 3 3E8H 5
COM 4 2E8H 3
COM 4 2E8H 5
• You will notice that both COM3 and COM4 can be set to an
IRQ (interrupt) of 5
• Your computer can share an IRQ (interrupt) between two
COM ports, as long as both COM ports are not accessed at
the same time
• Unlike an IRQ (interrupt), an address cannot be shared
between two hardware devices
For example:
• If you are sharing an IRQ with the mouse on COM3 and your
modem on COM4, when you run software to use the modem,
the mouse will freeze or become erratic and the machine will
halt and lock up.
• This is because there are two hardware devices which are
both trying to use the same IRQ (interrupt) at the same time.
• It is not recommended to share an IRQ (interrupt) in your
computer, and if you are experiencing problems similar to
this then contact your dealer.

5. Connecting Your PRO16SA
Follow these simple steps to connect the modem to your
computer:
1. Turn off your computer and all peripheral devices.
2. Examine the back of the modem and review the attached
interfaces as shown below.
3. Check to make sure that the power switch is OFF (DOWN).
Then plug the small end of the power adapter into the power
jack on the back of the modem and plug the power adapter
into a standard 115V AC wall socket.
4. Disconnect your present phone cord from the wall jack. Plug
the end of the phone cord that came with the modem into the
wall jack, and the other end into the RJ-11 jack at the rear of
the modem marked LINE. NOTE: Phone cable configuration
will vary for international settings.

5. Lastly, connect the modem to the computer’s serial port with
the serial cable. The modem is now ready to be tested and
operated. Turn your computer on now, then switch ON the
modem (switch in the UP position).
6. Run COMCHECK to ensure that your system sees the
modem. Insert the diskette containing the COMCHECK
program and type: A:\COMCHECK or B:\COMCHECK.
COMCHECK will automatically start Windows. If you have
another application that starts when you run Windows, you
will have to close it now in order to view COMCHECK.
Follow the on-screen instructions.
NOTE: You must have the Modem switch turned on (up
position) for COMCHECK to detect the modem. DO NOT
RUN COMCHECK IF YOU ARE RUNNING WINDOWS 95.
