Introduction

Some Particulars Worth Noting

· Your new Data/Fax modem operates at extremely high speeds: up to 33,600 bps for data communications and 14,400 bps for faxing. (With data compression activated, it has a throughput rate of up to 115,200 bps).

· Because it conforms to Hayes-Smart, Bell, and CCITT (ITU) standards, this modem is guaranteed to communicate with other modem/fax devices that operate at the same or slower speeds. Standard faxing conventions are also supported, and enhanced AT modem commands with S Registers are available.

· Other important features include: Auto Dial & Answer, Speed Buffering/Flow Control, Self-testing of power/analog/digital signals, Non-volatile memory to preserve modem operating characteristics after shut down, and a parallel 16550 UART interface (internally mounted models).

Our data/fax modems are easy to install and use. Each model will provide years of trouble free operation.

We include all necessary cabling, and provide a popular communications software package with a Graphical User Interface (GUI). This software will simplify faxing and modem use. (Check the Read Me First card for a complete listing of the items supplied with your model.)

Hardware Installation

The 33,600ifx high-speed internal modem is a half-card modem device designed for installation inside an IBM or compatible computer. (See illustration.)

The card is mounted on an expansion slot inside the computer it does not physically plug into an external COM port connector. However, it will still require its own COM port address and a unique IRQ interrupt.

Factory Defaults: The factory default for this internal modem is COM 4 and IRQ3. If you already assigned COM 4 and/or IRQ3 to other device(s), you will have to change the jumper settings on the card. If you have to change jumpers, you can change them to reflect these settings: COM port 1, 2, or 3 and IRQ 2, 4, 5, or 7. (See the section on Jumper Settings.

Note: If you want to use the factory defaults but have an I/O expansion card with an external connector assigned to COM 4/IRQ 3, you should physically disable that external port on your I/O board or electronically disable it within BIOS if your system allows you to do so.)

Step 1: Determining Which COM Ports & IRQ’s to Use

Before installing the internal modem, you must know if the COM port 4/IRQ 3 defaults can be used or if they have to change. You may do this follows:

· If you have Windows 95, click Start, select Settings and click Control Panel. Select the Control Panel’s System icon and click on the Device Manager tab. With Computer highlighted, select Properties and the View Resources tab to determine current system IRQ assignments (use Windows Help as needed).

· If you have Windows 3.x, type MSD [Enter] at the DOS prompt (e.g., C:\DOS or C:\WINDOWS) to access MS-Diagnostics. MSD will help you determine COM port and IRQ assignments; follow the on-screen prompts for instructions. (You can also refer to your system manual for information on IRQs and COM ports.)

Step 2: Changing COM and/or IRQ Jumpers

If you cannot use the factory defaults, change the jumpers on the internal card to reflect the ones you can use.

Step 3: Installing the Modem Card

After your COM port and/or IRQ jumpers are correctly set, install the modem card in your IBM or compatible PC as follows:

1. Turn off the computer and unplug the system from its wall socket.

2. Remove the computer cover mounting screws.

3. Remove the computer’s cover being careful not to damage the internal cabling.

Note: Before handling internal components , you may want to ground yourself with an anti-static wrist-strap. (You do this as a precautionary measure to protect electronic component from a possible discharge of static electricity from your body.)

4. Select an available expansion slot and remove the screw that secures the metal expansion slot cover. Save the mounting screw.

5. Carefully align and insert the internal modem card in the expansion slot.

6. Fasten the modem card’s mounting bracket to the rear of the chassis with the screw removed in step 4. Make sure that card is properly seated in place.

7. Connect one end of the supplied telephone cord to a telephone company wall jack Connect the other end to the line receptacle at back of the modem (see below). You may also connect a regular telephone receiver to the telephone receptacle at the top of the bracket , but the phone and the modem can’t be used simultaneously.

8. Replace the computer’s cover and connect its power cord. (Do not turn on the system until instructed).

Windows 3.1/DOS Installation

If you have a Windows 3.x system, check the port setting before you continue. Turn on the computer. Click on Control Panel and Ports. Click and check Settings for COMx (where COMx is the port you have jumpered the modem to), (19200 and Hardware) and Advanced Setting for COMx (for the port and IRQ you are using). You may now install the internal modem’s communications software.

Windows 95 Installation

Before installing the fax/data communications software, Windows 95 users must do the following:

1. Turn on the system and launch Windows 95. (If your modem was detected skip to step 5, otherwise continue with step 2.)

2. Click Start, select Settings, click on Control Panel, and double click Modems.

3. From the Modem Properties window (General tab) click Add.

4. Click on Don’t detect my modem and click Next.

5. Insert the Delrina 4 in 1 or QuickLink II disk into floppy drive A (or B).

6. Click Have Disk and select a drive letter (A or B) as necessary.

7. Select Newcom 33,600ifx and click Next.

8. Click Communication Port COM4 (if you changed jumper settings use that port number), click Next, and click Finish.

9. Click Properties, set the Maximum speed to 115200, and click OK. Click Close to return to Control Panel.

10. From the Control Panel, double click on the System icon. Then click on the Device Manager tab.

11. Double click Ports (COM & LPT), highlight your port, and click Properties.

12. Click Port Settings and set Bits Per Second to 115200. Also set Flow Control to Hardware and click OK.

Troubleshooting

Modem doesn't respond	- Adapter card is not secure in slot - Wrong COM port selected - If COM port 1 and 3 share the same IRQ (or if COM 2 and 4 share an IRQ) try disabling the physical port assigned to the modem.
Cannot connect	Check telephone lines and cords Check communications software - Configuration setup - Initialization string and dial string.
Characters appear twice on screen	Set communications software for full duplex (not half duplex)
Characters do not appear on screen	Set communications software for half duplex (not full duplex)
Incomprehensible characters appear on screen when a connection is made.	Change communications data bits, parity, and stop bits (normally 8, None, 1) to 7, EVEN, 1 or vice-versa or what your receiving terminal requires.
Software says to ignore DTR (Hayes default) but non volatile memory is set to follow DTR.	Change the setting by typing in the following: AT&D0&W0&Y0
Software requires DCD to be always ON (Hayes default) but non volatile memory is set so that DCD follows carrier.	Change the setting by typing in the following: AT&C0&W0&Y0
Modem's power-on setup is not what communications software wants.	Be sure you understand what power-on software setting is required. (Refer to Memory Modules, page 15 of the manual)

 

Communications Software

After setting up an internal or external modem, you should install the supplied communications software. It is general purpose communications software and it is user friendly, e.g., it simplifies dialing, data communication, and fax operations. (Follow the installation instructions found in the accompanying manual and use the supplied disk.)

If you have an IBM or compatible PC, you can also use Microsoft’s Terminal icon (or Hyperterminal icon for Windows 95) for general communication purposes. If you already have your own communications software you may use it instead.

Sending Commands: Enhanced AT Commands and S-Registers for this modem are found in the Chapters 3 and 4 of the manual.

Note: Many Bulletin Board Services (BBS) like Compuserve, America On-Line, Prodigy, etc., provide you with their own communications software. Some tips for using them follows:

Software Setup Tips (Use Hardware Flow Control, except for Compuserve):

American On-Line: Newcom 28.8 efx or 28.8ifx (or 33.6 when available)
Bulletin Boards (BBS): AT&F&C1&D2S95=3&K3%C3(rts/cts)
Compuserve-Hayes Comp: AT&F&C1&D2S95=3&K4 (Xon/Xoff) or &K3 RTS/CTS
Dumb Terminal: AT&F&C0&D0S95=3%C3&W0
Fax Modem Class 1 or 2
Internet Access-Hayes Comp: AT&F&C1&D2S95=3&K3%C3(rts/cts)
