Section One - Introduction The 14.4 Kbps Series FAX/Voice/Data Modem connect your computer to all popular high speed modems available today. This manual describes the hardware installation procedures for your new modem product. Additional information on AT commands and S-registers are provided so that your system can be customized for a particular operating environment. Section Two - Installation This section will provide step by step instructions on how to install your new 14.4 Kbps FAX/Voice/Data modem.
. If you have one or more serial ports on the back of your computer, reconfigure your modem. Your modem is shipped set to COM1 on IRQ4. Reconfigure the modem to either COM3/IRQ5 or COM4/IRQ2 (refer to Table 2-1 in Section 2.4). Figure 2-2 4. Remove your computer's cover Expansion (refer to your computer's owner Slots manual). 5. Select any available half-card slot, and then remove the slot cover (refer to Figure 2-2). 6.
Address should already be set by Windows to the COM port address used by the modem (refer to Table 2-1). Change the Interrupt Request Line (IRQ) to match the IRQ on the modem. If you have set the modem to COM4/IRQ2, do not select IRQ2. You will need to set the IRQ in Control Panel to IRQ9 for Windows to recognize the modem. (In an operating system designed for 286 or better machines, IRQ 9 is equivalent (redirected) to IRQ2.
2.4 COM Port and Interrupt Settings If your computer is equipped with one or more serial ports, you will need to change the COM Port setting on the modem (to either COM 3 or 4), or disable the PC's built-in COM port. An IRQ (interrupt request) is a signal generated by an I/O device that notifies the computer of incoming data. Your internal modem is capable of accessing IRQs 2, 3, 4, and 5. I/O devices in your computer cannot share an IRQ with another device at the same time.
combination needed for your application. Any time the COM or IRQ setting for the modem is changed, the settings in the software must be changed to match. 2.5 Using Fax, Voice, and Speakerphone Capabilities of the Modem Your modem has built-in advanced FAX, Voice, and Speakerphone functions. These functions are accessed through software. Please consult your FAX/Voice/Speakerphone software manual about procedures on using these functions.
provide a user friendly method of accessing the functions you need (i.e. dialing or answering calls). 2.8 Where To Go From Here You should familiarize yourself with the functions available from the included software by reading its manual. You will be accessing most, if not all, of the modem's functions from this software. You may also use any other commercially available communication software with the modem.

If the line sounds noisy, you may have difficulty connecting to the remote device. Modem makes a connection but no data appears on your screen. 1. The remote system may be waiting to receive your data before it begins. Try pressing the ENTER key a few times. 2. Make sure the correct data format (data bits, stop bits, and parity bits) and flow control (RTS/CTS) method are being used. 3.
1. Make sure the correct modem type is selected in the Voice/ FAX software. Use “Cirrus Logic” or similar selection. Do not select “Rockwell or Rockwell ICS” configuration. Section Seven - Specifications CCITT/Bell Std. V.42bis, V.42, V.32bis, V.32, V.29, V.27ter, V.22bis, V.22, V.21, V.

“PHONE” on the back of the modem. Follow specific instructions in the FAX/Voice/Speakerphone software on recording and playback of voice prompts. 2.6 Testing Your Modem After Installation In order to test your modem you should be familiar with your communication software. Load and set up your communication software and enter into “terminal mode.” Make sure that the COM Port and IRQ settings of the modem match the software. Type AT on your terminal screen and press ENTER.
Section Three - AT Command Set 3.1 Executing Commands Commands are accepted by the modem while it is in Command Mode. Your modem is automatically in Command Mode until you dial a number and establish a connection. Commands may be sent to your modem from a PC running communication software or any other terminal devices. Your modem is capable of data communication at rates of: 300, 1200, 2400, 4800, 9600, 14400, 19200, 38400, and 57600 bps.

Similarly, IRQ settings must be set correctly to receive data from the modem. 3. Make sure that your modem is initialized correctly. Your modem may have been initialized to not display responses. You may factory-reset the modem by issuing AT&F and press ENTER. The factory default allows the modem to display responses after a command has been executed. 4. Make sure the baud rate setting in your software is set to 57600, 38400, 19200, 14400, 9600, 2400, 1200, or 300 bps.
Modem experiences errors while communicating with a remote modem. 1. Make sure the DTE speed is the same as the modem connection speed when in Direct Mode (\N1 command in effect). 2. Make sure the remote system and your modem use the same communication parameters (i.e., baud rate, data bit length, parity, and stop bit). 3. Make sure RTS/CTS hardware flow control is enabled and XON/XOFF software flow control is disabled in the communication software. 4.
