This document contains all the information an experienced user needs to install the Intel 2400 BPS modems. If you're not an experienced user, you should use the modem's manual for installation instructions or have your dealer install the modem.

Intel has made the following 2400 BPS modems:

2400B V.42bis

Internal modem for IBM PC, PC XT, PC AT, COMPAQ 386 and 100% compatible computers. Supports V.42bis data compression standard.

2400e V.42bis

External Modem for any computer with an external RS232 port connector. Supports V.42bis data compression standard.

2400B Classic

Internal modem for IBM PC, PC XT, PC AT, COMPAQ 386 and 100% compatible computers.

2400B Modem 2

Internal modem for IBM PS/2 Models 50, 50Z, 60, 70 and 80, and 100% compatible computers.

2400EX

External Modem for any computer with an external RS232 port connector.

Refer to the installation sections that apply to the modem you're installing.

Before installing any new device (modems included), always verify that your computer is operating correctly. Fix any existing problems BEFORE installing an Intel modem.

Once you know the computer is operating correctly, use the steps outlined in the appropriate section to install the Intel modem.

Some Intel 2400 V.42bis internal modems have DIP switches and some have jumpers. For boards with switches, set the switches to the "On" or "Off" position according to the table. For boards with jumpers, "On" means cover both pins with the jumper at the indicated positions. "Off" means do not install a jumper in that position or install the jumper on only one pin (so it doesn't get lost).

NOTE: This modem does not support the non-standard address/IRQ settings for COM3 (3E8/IRQ 5) and COM4 (2E8/IRQ 2).

Before installing the 2400B Classic Modem into the computer, set its DIP switches for an address not used by any other serial ports or mouse in your computer. If you have just one serial port, COM2 should work fine.

The 2400B Modem 2 has no switches.

The 2400EX & 2400EX MNP external modems have no switches.

1. Turn off the power switch on the system unit and any attached equipment.
   
   
2. Remove the system unit's cover.
   
   
3. Insert the modem into an empty slot inside the computer.
   
   
4. Replace the system unit's cover.
   
   
5. Plug one end of the telephone cable provided with your modem into the connector labeled LINE and plug the other end into the wall jack.
   
   
6. To continue using the phone, connect it to the modem by plugging the free end of the telephone's cord into the connector labeled PHONE on the modem.

7. Turn on the computer and boot up using the Reference Disk.
   
   
8. Press Enter when the IBM logo appears.
   
   
9. Type N when asked "Automatically Configure System?".
   
   
10. If you haven't already done so, make a backup copy of your original Reference Diskette.
    
    
11. Select Copy an Option Diskette to copy the Intel 2400B Modem 2 Options diskette to your Reference Diskette.
    
    
12. Select Set Configuration from the Main Menu.
    
    
13. Select Change Configuration from the Set Configuration menu.
    
    
14. Select a serial port for the 2400B Modem 2 to use which does not conflict with other serial ports in your computer. SERIAL_2 usually works fine. An asterisk (*) appears when the current choice conflicts with an existing serial port.
    
    
15. Save the configuration information and exit from the program. Remove the Reference Diskette from drive A and put in a safe place.

1. Obtain a cable which has a 25-pin connector on one end and a connector on the other end that mates with the serial port on your computer (usually either 9-pin, 25-pin, or DIN connector). This cable is not included with the 2400EX.
   
   
2. Turn off the power switch on the system unit and any attached equipment.
   
   
3. Connect the 25-pin end of the cable to the connector on the 2400EX modem's rear panel. Tighten the connector screws.
   
   
4. Connect the other end of the cable into your computer's serial port. Tighten the connector screws.
   
   
5. Connect the modem power supply cable to the round connector on the back of the 2400EX.
   
   
6. Plug the power supply into a wall outlet.
   
   
7. Plug one end of the telephone cable provided with your modem into the connector labeled LINE and plug the other end into the wall jack.
   
   
8. To continue using the phone, connect it to the modem by plugging the free end of the telephone's cord into the connector labeled PHONE on the modem.

Follow these steps to run the TESTCOM program to verify the modem's operation:

1. Turn on the modem.
   
   
2. Insert the Intel modem diagnostics diskette into drive A and set the default drive to A.
   
   
3. Type TESTCOM and press Enter.
