Installation Procedure
Step
Procedure
1 Make sure your computer and any peripheral equipment connected to it are turned off. Failure to do so may
damage both your ISI card(s) and your PC. The MultiModemISI may be installed in a PC-AT, 386, 486, or
Pentium equivalent ISA or EISA bus computer.
2 Remove the cover of your computer as instructed in your computer’s documentation.
3 Locate the unused slot(s) which you will be using for your MultiModemISI card(s), and remove the slot cover(s)
per the instructions in your computer’s documentation.
4 Check the settings of the I/O address switch and the IRQ jumper to ensure that they are set properly for your
installation.
Note: One MultiModemISI can be paired with an auxiliary module (model #ISI3334/EC) when it interfaces with
on-board connectors attaching both cards; effectively providing 8 modem functionality. For details on this
process, see Appendix F .
4a The default setting for the MultiModemISI’s base I/O address is 210 hex. The default value for the IRQ jumper is
IRQ 10. Choose the IRQ value by covering the appropriate pins with the shorting plug (supplied). If your system
requires a different setting or if you are installing multiple cards, refer to Appendix E for a table of valid address
settings.
5 Install the MultiModemISI card(s) into the selected expansion slot(s) in the same manner as any other add-on
card, as instructed in your computer’s documentation.
6 Fasten the retaining bracket to the computer chassis and replace the cover.
7 Your MultiModemISI card(s) requires a modular
LINE JACK . This is typically an RJ11C or RJ11W jack, but
could also be an RJ12 or RJ13 jack. To connect the modem(s) to the PSTN line(s), plug one end of the RJ11
cable(s) that is provided with the modem into the LINE JACK connector(s) and the other end into the phone-
company-provided RJ11C or RJ11W modular phone jack(s).
Note: Any cables connected to the computer must be shielded to reduce interference.
8 Turn power on to the computer and proceed to the next section, Driver Installation , to install the MultiModemISI
drivers.
