Introduction Thank you for purchasing the Actiontec PCI Pro 56K internal modem. The PCI Pro incorporates the latest technology in controller-less V.90 modems for the PCI bus. This technology improves the performance and capabilities of personal computer fax/modems. The use of the PCI Bus frees the user from having to use an ISA slot which is most likely already being used by another peripheral. Almost every PC has at least one free PCI slot.
Do This First Please read the following tips carefully before attempting to install your new modem. For Windows 95 and Windows 98 Installations Be sure to remove all other modem drivers from your operating system. To do this, right-click My Computer, choose Properties from the menu that appears, then click on the Device Manager tab. Double-click the Modems icon in the list of devices to show the modems installed. Click once on the icon next to any modems in this list to select them.
If you are going to use the Telephone Answering Machine (TAM) functions of the modem and you are running Windows 95, you need to install a software component called Unimodem V. If you have Windows 95 OEM Service Release 2 (Version 4.00.950 B, hereafter referred to in this manual as Windows 95B) or a later version of Windows, this component comes standard as part of the operating system.
For Windows 2000 Professional Installation Before installing your new modem, be sure to remove any modems and their drivers from your operating system. On the taskbar, click Start. On the Start menu click Settings, then click Control Panel. Double-click the Phone and Modem Options icon. Click the Modems tab to bring it to the front. Highlight the modem you wish to remove and click Remove. Repeat this process for as many modems as you would like to remove.
Installing The Modem Always discharge static electricity before handling your modem. You may discharge static electricity by touching a grounded metal structure or by using any commercially available grounding strap. Make sure the expansion slot type is 16-bit, which has two slots to fit the ISA card. 8-bit slots have only one connector. If you use an 8-bit slot, the modem will not have access to the higher interrupts (IRQ 912).
5. Firmly but gently insert the modem into the available PCI expansion slot. Ensure that the card is seated properly before securing it with the screw removed in Step 4, as shown in the following diagram: Figure 3: Installing The Modem 6. Put the chassis cover back on the computer. 7. Be sure that all power switches are in the OFF position, then reconnect the power cables to the computer and its peripherals. 8. Connect the telephone line cable to the Line (Telco) jack as shown in Figure 7. 9.
Connecting Devices to the Modem Figure 4: Connecting Devices On the rear panel of your modem are input jacks to connect devices to the modem. As shown in the diagram, there are jacks for connection to a “phone” and to a phone “line.” The connector labeled Line (Telco) is meant to be connected to a standard analog phone line. To help reduce the load on your phone line, it is recommended that the modem be the only device connected.

Installing Communications Software If your modem came with a communications software package, it is strongly recommended that you use this software for your modem. Its default installation parameters have been specially configured to work with this modem. The Users Guide for this program can be found in Adobe Acrobat (PDF) format on the installation CDROM. Some configurations are packaged without communications software. Check your packaging to see if communications software is included.
A modem based Telephone Answering Machine works by using a sound card equipped with a microphone to record an outgoing message. This message is stored as a .wav file which is transferred to the modem by the application program when an incoming call is detected. The modem’s internal electronics converts the digital information contained in the .wav file into an audio signal which is then sent over the phone line. The person calling hears your outgoing message and responds with an incoming message.
Troubleshooting This section lists some common problems and offers suggestions for a solution. It is important to remember that this modem is a Windows-based modem and requires 32bit virtual device drivers. It therefore cannot work in Windows 3.1 which cannot use these drivers. The modem also cannot work in DOS regardless of version. It is a software installed device and has no provisions for manual configuration.
If either of these conditions are present, correct them. Make a note of the Com port and IRQ the modem is using. If the Device Status area shows some error message, it will generally be about a conflict. Go to the Resources tab and read the Conflicting Device List. If a conflict is present, click to deselect “Use automatic settings” and select a configuration that does not cause conflicts.
Step 4: Does Not Install The most likely reason for a non-installation in Windows 95 or 98 is a lack of IRQ resources. The modem needs one IRQ and two I/O addressees in order to function. Modern computer systems are usually equipped with sound card, CD-ROM drive, Hard-drive, floppy drive, video card, two COM Ports, one LPT port, keyboard, and a mouse. Each of these devices require at least one IRQ (interrupt) in order to function.
BIOSs don’t allow individual selection of interrupts for ISA, Plug-N-Play, or PCI.) The interrupt settings can be called “ICU”, “ICU/PCI”, “PCI”, or “PNP depending on your BIOS version and manufacturer. Do not set this interrupt to “ISA” only or to “Legacy ISA”. Be sure to Save the settings before exiting the BIOS Setup. Under some situations, you will find that freeing an interrupt does not solve your installation difficulties.
Plug-N-Play settings. These settings can be found within the “Advanced,” “PNP/ PCI Configuration,” or “Plug-and-Play Configuration” sections depending on the BIOS Manufacturer. Next, verify that at least two IRQs have been set so that the PCI bus has access to them (some BIOS don’t allow individual selection of interrupts to ISA, Plug-N-Play, or PCI). These settings can be called ICU, ICU/PCI, PCI, or PNP depending on your BIOS version and manufacturer.
Can’t Connect at 56K Note: Current FCC regulations limit your maximum connection rate to 53Kbits / s. The number you are calling may not support V.90 or K56flex protocols. Some ISPs (Internet Service Provider) have special numbers that you must call to connect to 56K. Contact your service provider and ask if the number you are calling supports V.90 or K56flex connections to their service. Check the maximum speed setting in the Modem Properties window. On the taskbar, click Start.
connection can be established. The telephone company must have you connected to the PSTN (Public Switched Telephone Network) in a particular way. The modem you are calling must support the same protocol. The phone line must be free of distortion and noise. The phone wiring in your house or building must be in good condition and so on. Check to see if you have good voice communications while talking to friends or relatives.
