Section Two - Installing The Modem
2.1 Hardware InstallationThe following steps instruct you to install the external modem. You will
also need a RS-232 serial cable connect to your computer. For IBM compatiblecomputers equipped with a 25-pin serial port, you will need a standard 25-pinto 9-pin "straight-through" serial cable. If you have a 9-pin serial port on yourPC, you can use a 9-pin to 9-pin "IBM AT" type serial cable. For Macintoshcomputers, useing a high speed Macintosh serial cable can support hardwareflow control signals.
1. Turn off the computer.2. Plug the male (9 pins) end of the serial cable into the connector marked
COMPUTER on the back of the modem (see Figure 2-1).
3. Plug the other end of the serial cable into your computer's serial port(COMx; x=1,2,3... on IBM and compatible PCs).
4. Plug the telephone cable into the connector marked LINE on the back ofthe modem.
5. Plug the other end of the telephone cable into a telephone wall jack.6. Make sure to verify the modem power switch is on the off position (located
on the front panel). Plug the AC adapter's power cord into the connectormarked POWER on the back of the modem.

7. Plug the transformer end of the AC adapter into a standard AC wall outlet8. Optionally connect : (1) your telephone to the modem's PHONE connector.
Lift the handset and listen to a dial tone to check for a working connection.(2) a speaker to the modem's SPK connector, and (3) a microphone to themodem's MIC connector.
9. Turn on the modem. The modem should perform a self-test, and then beready for use. You may now turn on your computer.
2.1.1 Indicator LightsYour modem (external model only) features LED indicators on the front
panel that report modem status:
MR Modem Ready On when modem is ready to work TR Terminal Ready On when DTR signal is active SD Send Data On when modem is transmitting data to remote modem RD Receive Data On when modem is receiving data from remote modem OH Off Hook On when modem is off hook CD Carrier Detect On when remote carrier has been detected AA Auto Answer On when modem is Auto Answer after ring setected HS High Speed On when modem set to 9600 bps or higher CS Clear to Send On when CTS signal is active
This completes the external modem installation. Proceed to Section 3 forinformation on installing and configuring your communication software.
2.2 Testing Your ModemTo confirm that the modem is working properly after installation, run a
modem communication program and set the software for the correct modemCOM port (internal modem factory defaults to COM4). At the software'sterminal mode prompt, type AT followed by the ENTER key. The modem shouldrespond by displaying an OK (or 0). The OK (or 0) response indicates thatthe modem is working properly. If the modem does not return the properresponse, refer to Section 5 for troubleshooting information.

2.3 Using Your ModemCommon modem functions (i.e. dialing, file transfer, faxing) are performed byusing communication software in conjunction with the modem. The commu-nication software included with your modem provides a user friendlyinterface for all common modem functions and should be sufficientfor all of your communication needs. The modem may also perform basiccommunication functions (such as dialing) via the AT commands. A list anddescription of all AT commands appears in Section 6. Since the communica-tion software is designed to shield the user from the difficult and cumbersomeAT commands, we strongly suggest that all modem operations be performedvia the software.

Section Four - Installing and Configuring CommunicationSoftware
Install the communication software according to the software user'smanual. Be certain that your software is configured to communicate with themodem on the same COM port and IRQ line used by the modem.
You may be prompted by the software to configure certain communica-tion parameters. We suggest the following settings:
Baud Rate: 115,200 bps Data bits: 8
Parity: None Stop bit:1
Flow Control: RTS/CTS Initialization string: AT&F
The AT commands used by the modem are compatible with the commandset used by Intel modems. Select a Ambient modem type if prompted by yourdata communications software. Select Generic Class or Ambient modemtype when prompted by your FAX or Voice software.
COMPUTER on the back of the modem (see Figure 2-1).
4.1 Accessing the Fax/ Voice/ SpeakerphoneThe Fax, Voice and Speakerphone functions of your modem are
application driven and are accessed only through application software.Consult your software manual regarding procedures on usingthese features.
Many types of Voice software support recording and playback of voicefiles. To recordor playback voice with your modem, attach a telephone to themodem, or optionally, attach a speaker and microphone to your modem's SPKand MIC connectors. Follow the instructions provided with your Voicesoftware to record and playback voice files.
4.2 Using Your ModemCommon modem functions (i.e.dialing, file transfering, faxing) are
performed by using communication software in conjunction with the modem
The modem may also perform basic communication functions (such asdialing) via the AT commands. A list and description of all AT commands appearin Section Six.

Section Five - TroubleshootingYour modem is designed to provide reliable and trouble-free function-
ality. However, should you experience any difficulty, the information containedin this section will assist you in determining and resolving the source of theproblem. If you can not resolve your situation after reading this chapter, contactyour dealer or vendor for assistance.
5.1 Modem does not respond to commands.1. Make sure the modem is not configured with a conflicting COM port .2. Make sure the communication software is configured with the correct COM
and IRQ settings (same COM port and IRQ as the modem). Yourcommunication software will not be able to send or receive any data if itis not configured to match the COM and IRQ settings for the modem.
3. Make sure the modem is properly initialized by the communication software.Your modem may have been improperly initialized by the softwarebecause you have selected an incorrect modem type. You may also beprompted to enter an initialization string” by the software. Use AT&F asyour initialization string.
friendly interface for all common modem functions and should be sufficient forall of your communication needs.
4. If you are running Microsoft Windows 3.1, make sure that the modem isproperly configured in Windows .
5.2 Modem dials but does not connect.1. Make sure the IRQ setting is identical to both of the modem and the software.2. Make sure the phone line is working properly. A noisy line will prevent a
proper modem operation.
5.3 Modem makes a connection but no data appears on yourscreen.1. Make sure all communication parameters (baud rate, data, stop, and parity
bits) are properly configured and are identical to both sides. Be certain thatthe hardware flow control (RTS/CTS - default) is enabled in both of themodem and the communication software.
2. Press the ENTER key several times. The remote system may be waitingto receive your data before it starts.
3. Make sure the correct terminal emulation mode is being used in thesoftware (refer to software manual).

Section Six - AT Command Set
6.1 Executing CommandsYour modem is in Command Mode upon power-on and is ready to receive
and execute “AT" commands. The modem remains in Command Mode until itmakes a connection with a remote modem. Commands may be sent to themodem from an attached terminal or a PC running a communication program.
This modem is designed to operate at common DTE speeds ranging from115.2 Kbps to 300 bps. All commands and data must be issued to the modemusing one of the valid DTE speeds.
6.2 AT Commands & FormatAll commands must begin with the AT prefix, followed by the command
letter and ended with the ENTER key. All default settings are printed in boldtext. Spaces are allowed in the command string to increase command linereadability but are ignored by the modem during command execution. Allcommands may be typed in either upper or lower case, but not mixed. Acommand issued without any parameters is considered as specifying thesame command with a parameter of "0".
Example: ATL [ENTER]
This command causes your modem to lower its speaker volum
