Chapter 1 Installation

 

Chapter 1 provides detailed instructions for installing your modem.

 

1.1 Checking your components

Unpack your components and make sure you have the following items:

 

 

When you open your package, make sure all of the above items are included and not damaged. If you see that any components are damaged, please notify your dealer immediately.

 

1.2 What else you need

 

To complete your data communication system, you will need the following items :

 

 

1.3 Installing the modem

 

The following instructions explain how to install the modem in a IBM compatible type personal computer. If you will be installing the modem into a different computer, refer to the manual that accompanied your computer or contact your computer dealer for instructions on installing the modem in your personal computer.

 

1.4 Removing the computer cover

 

Turn off the personal computer's power. No power must be applied to your computer when you install the internal modem and computer could be damaged.

Make sure you can freely access the back of the personal computer.

Unscrew the necessary screws to loosen the computer cover. Then set the screws in a safe place and remove the computer cover.

 

1.5 Inserting the modem

 

The internal modem can fit into any available PCI slot in your personal computer. To insert the internal modem in your personal computer:

 

  1. Position yourself so that you can easily access the computer's expansion slots.
  2. Select any available half-card slot into which you can install the internal modem.
  3. Remove any slot cover that may be over the slot. Then remove the slot cover and keep both in a safe place (you will need the screw to secure the internal modem and you may need the slot cover if you decide to remove the internal modem in the future).
  4. Hold the internal modem above the slot you selected, making sure the modem's edge connectors are pointing down toward the base of the personal computer (see Figure1-3).
  5. Carefully slide the modem into the PCI slot, applying even pressure to both ends of the modem. Stop inserting the modem when its gold-plated edge connectors are aligned with and completely fit into the base of the computer.
  6. If you removed a screw from the slot cover, use that screw to secure the modem in the PCI slot. You may want to test the modem's telephone connection (described in the next section) before securing your modem.
  7. Use the cover-mounting screws to secure the computer cover.

Figure 1-3. Inserting the modem

 

1.6 Connecting to the telephone line

 

Use the following procedure to connect your modem to the telephone line:

 

  1. Make sure you have an RJ-11 telephone jack. If you need a modular jack, either obtain a telephone adapter from a telephone or electronics store and follow the installation instructions provided with the adapter, or have your local telephone company replace your existing telephone jack with a modular-type jack and your existing telephone cord with a modular cord.
  2. Unplug your telephone's cable from the wall jack.
  3. Take one end of the modular telephone cable supplied with the modem and plug it into the LINE modular telephone jack on the back of the modem (see Figure 1-4).
  4. Plug the other end of the telephone cord into the telephone jack on the wall, as you would any modular telephone.

 

1.7 Connecting to your telephone

 

Your modem is so convenient, it provides a second modular telephone jack that lets you connect your telephone to the same telephone line the modem is using. This lets you manually dial data calls or make voice calls when you are not using your modem.

 

  1. Use the following procedure to connect your telephone to your modem:
  2. Connect the telephone's modular cord into the PHONE jack on the back of your modem (see Figure 1-4).

 

Lift your telephone's handset and listen for a dial tone.

1.8 Verifying your connection

Before you proceed to next step, make sure your connection matches the one shown in Figure 1-5.

ESS 56K PCI

Figure 1-5. Completed modem installation

 

If you connected the modem to a computer, place the computer into terminal mode and complete the configuration information required by the software.

Refer to your computer manual to find out the appropriate command to use.

 

Then use the following procedure to verify that your connections:

 

  1. Type AT and press the Enter key. If your system is operating properly, your modem sends an OK response to your screen and wait for your next command.
  2.  

    If you did not receive a response, make sure your computer is sending commands to your modem. If this does not solve your problem, contact your computer dealer.

     

  3. Use your communication software to prepare your computer to dial a call. Then type AT D x phone number, where x is either T for touch-tone dialing or P for pulse dialing and phone number is the telephone number that your modem is using.
  4.  

    For example, if your modem is connected to the telephone line 555-2121 and Touch-Tone dialing is supported in your calling area, type ATDT 5552121.

     

  5. Press the Enter key. You should receive a BUSY response and you should hear the busy signal through the modem speaker because the modem is calling itself.

 

Your modem is now ready for operation. Refer to the manual that came with your communication software to begin communications. If you will be communicating directly with your modem, or if you want to find out more about the modem's operation, proceed to Chapter 2.

 

 

1.9 Modem Driver Installation ( PnP)

  1. Turn on the computer.
  2. As Windows 95 /98 starts up , it informs you that it has found new hardware and starts the Hardware Installation Wizard.

  3. Insert the driver installation diskette before continuing with the Hardware Installation Wizard.
  4. Click Diskette provided by manufacturer and select the driver installation diskette when the Hardware Installation Wizard prompts you to select the driver you want to install.
  5. For example , if your disk driver is driver A in your system , select A:\ under "Copy manufacture's files from:".

    Note :In some version of the Windows 95 operating system , the following may occur , "Cannot find ESxx_.vxd . Insert Windows 95 CD ." Click OK and redirect the Hardware Installation Wizard to the driver installation diskette again.In some version of the Windows 95 operating system , the following may occur , "Cannot find ESxx_.vxd . Insert Windows 95 CD ." Click OK and redirect the Hardware Installation Wizard to the driver installation diskette again.

  6. Follow the instructions of the Hardware Installation Wizard.

Chapter 2 AT commands and Result Code Responses

 

Chapter 2 describes the format to use when typing modem commands. Chapter 2 also describes the responses that your modem sends to your computer screen when you execute, or try to execute, modem commands.

 

These commands are issued by using a data communications program. An example of such a program is HyperTerminal, which is installed by Windows 95 when you install your modem hardware.

 

If you will be using a communication software program to make data calls, you will probably not need to type commands, because your software program will handle these tasks for you. Similarly, you will probably not see the responses because your software program may intercept them.

 

However, if you perform data activities directly with your modem, you will find the format for typing modem commands and modem response helpful.

 

2.1 Starting an AT Command Session

To start an AT command session , follow these steps:

  1. Click the Start button on the teskbar.
  2. This opens the Start menu.

  3. Select Programs.
  4. This opens the Programs menu.

  5. Select Accessories.
  6. This opens the Accessories menu.

  7. Select HyperTerminal.
  8. Double-click the icon labeled Hypertrm.exe.
  9. This opens the Connection Description dialog box.

  10. Enter the name "Test" and click OK.
  11. This opens the Phone Number dialog box.

  12. Enter a number (for example, 555-1234) and click OK.
  13. Note: Before clicking OK, be sure the correct modem is selected in the Phone Number dialog box. Select the modem from the Connect Using list.

    This opens the Connect dialog box.

  14. Click Cancel.
  15. This closes the Connect dialog box, leaving the HyperTerminal windows. You don't actually want to dial the number, you just want try out some AT commands.

  16. Type AT&F and press the enter key.

The result is displayed in the HyperTerminal windows:

AT&F

OK

 

2.2 Entering Commands

AT commands all start with the AT prefix (except for A/ and +++). Write the commands in uppercase or lowercase letters, but don't mix uppercase and lowercase. If a command has a numberic varible and you don't enter one, the modem assumes the value is 0.

 

2.3 Using the Escape Command

Once you have connected, you can return from online mode to command mode using a Time Independent Escape Sequence (TIES). The escape character is "+" by default and can be change using S-register S2. Follow these steps to escape online mode:

  1. Enter the escape character three times.
  2. For example : +++. After entering the escape character three times, the modem responds with OK.

  3. Enter a valid TIES command.

The valid commands are as follows: AT, Ex, Hx, Mx, Ox, Qx, Vx, Wx, Xx, &Dx, &Kx, &Wx, and &Vx; where x is a variable. See the description of the AT command in question for details. After entering a valid command, you are in command mode.
