	2 Remove the cover of your personal computer.
	3 Select an empty slot ,and remove the metal slot cover using a small screwdriver.
	4 Press the card firmly into the selected expansion slot.
	
NOTE : While any unused 16-bit expansion slot may be used , we recommend choosing the slot
 which is farthest from other adapters, cables, and system components. This will reduce the
 amount of electrical noise that is coupled into the audio section of your card. 

	5 Insert the srew you previously removed from the slot cover through the top notch and the screw hole . Check that the telephone jack in the back of the card are unobstructed. 
	6 This card provides a connector that accepts audio signals from other device (typically an internal CD-ROM).( Connector P3 or P5). The connector allows signals from these other devices to be recorded into WAV files or sent to the LINE-OUT connector of the card. You will then have to refer to documentation for your CD-ROM to see whether it provides these signals on the correct pins.Locate the 4-pin connector that is used to connect a cable from the analog audio outputs of an internal CD player or other adapter that generates analog audio.
	This pins are set as follows:
	
	Pin1 - Left Channel Input
	Pin2 - Ground
	Pin3 - Ground
	Pin4 - Right Channel Input
	Important :This connection from a CD-ROM player is for transmitting analog audio from a music compact disc. This connection does not transmit digital computer data from a CD-ROM disc.
  	
	7 Connect the audio equipments to your cards connectors as follows:
	    - Audio amplifier with speakers, powered speakers to the Line-out connector.
	    - Audio player (for example ,tape,compact disc,etc.) to Line-in connector.
	    - Microphone to the Mic connector.
	
	8 Plug the telephone cable which comes with your card into the Jack as shown in Figure 2 ,then connect ANALOG telephone line and ANALOG telephone to the corresponding jack labled as LINE and  PHONE :

3.2 Audio Application	
	The following Mwave Audio Application for Windows 3.1 make up the Mwave Audio Application Option:
	Mwave Audio Control
	
	The following sections give brief overviews of these applets ans some directions for using them. Futher information on using each applet is included in its online help.
	
3.2.1. Audio Control

	The Mwave audio control applet allows you to control the sound section of your card. 
	Start the Audio Control applet by double-clicking its icon.
	The screen for the audio control is shown below:





	3.2.2. Using the Mwave Record Controls:

	The record control section can be thought of as the control section of a tape desk which selects the inputs, controls the record level and allows you to monitor its input signal.

	This card can record from one of three possible audio sources:
	Microphone
	Line-in
	CD Audio in

	The microphone source is from the Mic connector on the card panel. The Line-in source is from the Line in connector on the card rear panel. The CD source is from the internal CD-ROM drive.

	Select a button on ther left side of the Mwave audio control window under Record control gives you the following audio source option:
	
	Click on MIC  to record from a microphone. The microphone cord should be plugged into the MIC connector on the card rear panel.		
   Click on Line to record from the stereo Line in connector on the card rear panel.
	Click on CD to record from the internal CD-ROM.

	3.2.3. Using the Output control:
	
	You can think of the output control section as a stereo amplifier with three input  signals, controls to mix the input signals and a volume control for the output. This amplifier receives its input from applications which use the Mwave sound driver to play sound wave files, and from application which use the Mwave MIDI sequence files. You can independently control the amount of each amplifier inputs signal that mixed to generate the output signal whose level you control with the Master control.

   
	3.2.4. Mwave MIDI Synthesizer
	Your card can be a music synthesizer, creating realistic instrument sounds from a sequence of MIDI commands played on a MIDI keyboard or read from a MIDI file on your PC. The MIDI standard defines a very compact representation for music. MIDI is composed of a sequence of commands representing musical ebents, such as a key press on a music keyboard. 	

	The Mwave Windows Audio Device Driver provides a sampled sound MIDI synthesizer that exceeds the Base Mutitimbral requirements of the MPC1 and MPC2 specifications. The card plays MIDI files using a MIDI synthesizer implemented on its DSP. Three versions of the MIDI synthesizer are avaiable:16-voice, 24-voice and 32-voice.
	Choose the synthesizer by selecting the "Select Synthesizer" application in the Mwave MDSP2780 group. The 16-voice synthesizer allows more concurrency with the other function because it consumes less DSP resources. Use it when you need other DSP function at the same time(such as modem or FAX) The 24-voice synthesizer complies with the general MIDI specification and consumes more DSP resources. When the entire DSP can be dedicated to MIDI, select the 32-voice synthesizer for the best sound.
	
3.2.5. Qsound

	All versions of the MIDI synthesizer are enhanced with a Qsound process. Qsound is a signal processing techique used to deceive the acoustic response system of a listener. Audio from a stereo speaker that has been processed by Qsound can give the listener the perception that the speakers are displaced much further to the listeners left and right than they actually are.
    	This is particularly useful for a personal computer system, in which table space is limited, and a small set of speakers are located immediately adjacent to the computer. the angular displacement of the speakers to the listeners left and right is not sufficient ti give a decent stereo effect. But with Qsound processing, the listener can perceive sound coming from a variety of directions, some of which are significantly further ti the left and right than the actual location of the speaker. the net result is a sigfificatly improved stereo effect.To optimize the Qsound effect, sit directly in front of the computer with the speakers equally distant from both sides of the computer.

3.3 Game Application	

	3.3.1 Mwave Games Support 

	This card provides support for Sound Blaster compatibilty for games and audio in native DOS, DOS 
	sessions running under Windows. Mwave Games is not an application; it is a driver that allows your computer to work as if a Sound Blaster card is installed.  With this card, you can play DOS-based games that require a Sound Blaster card.  Mwave handles all the high quality digital sound provided by the game. 

	You can control the capabilites of Mwave Games using the Mwave DOS Software Settings utility.  See 
	Setting Mwave Games Mode for more information. 

	For best performance from DOS games, it is recommended that you play the games in native DOS. 
	When you open a native DOS session, basic Sound Blaster emulation is enabled by default.  You can 
	also enable Sound Blaster Pro emulation using the Mwave DOS Software Settings utility.  See Setting 
	Mwave Games Mode for more information. 

	3.3.2. Setting Mwave Games Mode 

	Mwave configures its games support based on the settings specified in the Software Configuration Utility.  
	You can configure your card in one of two ways: 
 
	 Basic Sound Blaster emulation, which includes FM Synthesized sound.  With this setting, you can 
	simultaneously operate the 14.4 Kbps modem. 

	 Sound Blaster Pro emulation with the option to set QSound, reverb, and chorus effects.  Although you 
	cannot operate the Mwave Modem with this setting, Sound Blaster Pro with effects provides optimum 
	quality to the sound produced by your DOS-based games. 


	See Changing Mwave DOS Software Settings for complete information on changing the configuration of the Mwave software.  




	3.3.3. Changing the Mwave DOS Software Settings

4.2 Using Mwave Data Modem

  	The Mwave Modem is a fax and data modem that runs in the DOS, Windows 3.1 operating environments.When you open any application that requires a fax or data modem for 
	communication (for example, WinFax Pro for Windows or ProComm Plus for DOS), the Mwave Modem starts automatically.  While the application is open, the Mwave Modem remains open and consumes DSP resources on your card. Therefore, when you finish using an application that requires the Mwave Modem, you should close the application instead of minimizing it.

	4                     Negotiates for a maximum of 256 bytes, but uses variable size blocks during the                                    
	                      MNP session(default)

	\B         Send Break
	
	The \B extended command causes the modem to transmit a break signal.  This command is valid only in on-line command mode.
	Syntax:  AT...\B...[CR]

	\K     Break Control
	
	This command controls the actions to be taken by the Mwave Modem upon reception of a break signal from either the DTE or remote modem.  The DTE may generate a break either through the UART hardware or by using the \B command.  Parameters 1-3 generate identical behavior for a non-ECL connection.  The default is \K3.
	Syntax: AT...\Kn...[CR]
	n              Usage
	0,NULL    When a break is received from the DTE and the modem is online, the modem enters the
	                escapes to command state and but does not issue a break to the remote modem.  When a
	                break is  received from the remote modem, it is reported immediately and is nondestructive
	                to any buffered data.
	1               Breaks cause destruction of any buffered data, and they are reported immediately. The       
	                 escaped state is not entered when  a break is received from the DTE.
	2               Breaks are nondestructive, and the break is reported immediately. The escaped state is not                    
	                 entered when a break is received from the DTE.
	3               Breaks are nondestructive, and the break is queued in sequence with any buffered
	                data and is reported in turn. The escaped state is not entered when a break is
	                received  from the DTE (default) 

	\L MNP Data Mode
	
	The \L extended command selects MNP stream mode or block mode to be used by the modem during an MNP session. The mode may not be changed once an MNP is established.
	Syntax: AT...\Ln...[CR]
	n                Usage
	0,NULL      Stream mode (variable size based on \A command) (default)

	\N         V.42 and MNP** Negotiation Behavior
	
       The \N extended command selects the MNP and V.42/V.42bis operational behavior. Whenever an Error Corrected Link (ECL) is established, the session will attempt to also get a compressed link if possible. A V.42bis compressed link will be attempted first. If that fails or if a "H0 has been issued, then an MNP5 compressed link will be attempted. If that fails or if a %C0 has been issued, a non-compressed link will be established.
	Syntax: AT...\Nn...[CR]
	
	n                 Usage
			0, 1, NULL      Both MNP and V.42 are disabled.
	2                 Enables MNP, and only an ECL connection is acceptable.  If  the MNP** negotiations fail
	                   or the auto fallback character is received, then hang up.
	3                 Enables MNP and falls back to an non-ECL connection if  the MNP** negotiations fail or         
                          the auto fallback character is received.
	4                 Enables V.42 error correction, and only a V.42 ECL connection is acceptable. If the V.42 
	                   negotiations fail, then hang up.
	5                 Enables V.42 error correction, and falls back to a non-ECL connection if the V.42
	                   negotiations fail.
	6                 Enables V.42 error correction, and falls back to an MNP connection if the V.42negotiations
	                   fail. If MNP negotiations fail, then hang up.
	7                Enables V.42 error correction, and falls back to an MNP connection if the V.42
	                  negotiations fail. If the MNP negotiations fail or the auto fallback character is received,then
	                  fall back to an non-ECL connection	(default)

	\Q          Set DTE Flow Control
	
	The \Q command selects the flow control method that your Mwave modem provides to your DTE to prevent applications from losing data in the case that the application cannot extract data from the modem as fast as it is being transmitted by the remote end of the communications link
	Note: CTS Flow control is not used in Mwave modems because it is not possible to overrun Mwave internal buffers. Applications can specify CTS hardware flow control, but the the modem will never drop CTS as internal receive overruns cannot happen in Mwave.
	Syntax:  AT...\Qn...[CR]
	n                Usage
	0,NULL      Flow Control Disabled.
	1               Returns ERROR
	2               Returns ERROR
	3                 Use the RTS (Request to Send) signal for bidirectional hardware flow control. When
                   the application turn RTS off, the modem stops transmitting data to the PC that the                       
                   Mwave modem is contained in. When RTS is on, the Mwave modem resumes sending
	            data (default)
	\T         Set Timer

	1              Enables MNP result codes	(default)
     
	5.5 AT Commands preceded by %

	%A   Define Auto Fallback Character
	
	The %A extended command defines a character to be used to abort the MNP negotiation process. The auto fallback character is a 7-bit character with no parity. The auto fallback character should not be set to the ASCII SYN character (decimal 22). This causes the MNP negotiation to be aborted for valid MNP frames.  The default is %A0, which disables the auto fallback feature.
	Syntax: AT...%An...[CR]
	n                 Usage
	0-127          Defines the ASCII decimal code to be used as the auto fallback character by MNP.
	%A0   (default)
	
	%C         MNP Compression Control
	
	The %C extended command controls the data compression to be negotiated for in MNP class five. This command may be issued at anytime, but will only take effect at the establishment of the next connection.
	Syntax: AT...%Cn...[CR] 
	n                  Usage
	0,NULL        No data compression.
	1                  Data compression is enabled for MNP class 5 (default)

	%E      Fast Rate Renegotiation Control
	
	The %E command controls the modem's response to a change in line quality and to requests for retrain or fallback/fall forward by the other end. This command only affects V.32 and V.32bis. When %E2 is active, the modem monitors the line quality. When line quality is insufficient to sustain the current connect speed, the modem will initiate a rate renegotiation to a lower speed within the V.32bis/V.32 modulation speeds (4800, 7200, 9600, 12000 and 14400 bps). The modem will keep falling back as needed until the speed reaches 4800 bps. If the line quality deteriorates further while connected at 4800 bps, the modems will hangup the telephone line. If the quality of the line increases, the modem will initiate a rate renegotiation to a higher speed if the modem currently has a V.32bis connection with the modem at the other end of the phone line. The rate renegotiation will be done without a retrain in this case.The modem will not increase the line speed if the modem is connected via V.32 to the other end of the  hone line. Fall forward via Fast Rate Renegotiation is not supported in the V.32 specification.
	Syntax: AT...%En...[CR]
	n             Usage
	0,Null      Disable Auto-Retrain and Fast Rate Renegotiation.

	S3           13      0-127    ASCII Character	Carriage Return Character.  S3 contains the ASCII 	code for the carriage return.  The character contained 	in S3 is used for the command line terminator and for 	output line terminator.
	S4          10      0-127     ASCII Character	Line Feed Character.  S4 contains the ASCII code for 	the line feed. The character contained in S4 is used 	for the output line terminator for text output (V1).
	S5           8       0-32       ASCII Character	Backspace character.  S5 contains the ASCII code for 	the backspace character. The character contained in 	S5 is used for editing an input line and is echoed back 	to the DTE to overwrite a character.
	S6         2       2-255     seconds	Blind dial wait time.  S6 contains the amount of time 	to wait (in seconds) after going off-hook, before 	dialing. This allows time for dial tone to be applied to 	the line.
	S7       60       2-255    seconds	Carrier wait time.  S7 contains the amount of time to 	wait for a data carrier. If a carrier is detected, a 	"CONNECT" result is returned, otherwise a "NO 	CARRIER" result occurs.
	S8        2       0-255     seconds	Comma wait time.  S8 contains the amount of time to 	wait for a comma command or dial modifier.
	S9        6       1-255     1/10 seconds	Carrier recovery time.  S9 contains the amount of time 	to wait between a return of the carrier in the on-line 	state and the acceptance of the carrier.
	S10     14       1-255    1/10 seconds	Lost carrier hang-up time. S10 contains the amount of 	time to wait between loss of the carrier and hang-up.
	S11     95     50-255    milli-seconds	DTMF dialing speed.  S11 contains the duration (ms) 	and inter-digit delay for DTMF tone dialing.
	S12     50     0-255     1/50 seconds	Escape code guard time.  S12 contains the guard time 	delay for recognition of the escape sequence.
	S24     0          0-1	Calling Tone. S24 enables/disables modem calling 	tone. 			ATS24=1enables tone, ATS24=0 disables tone. 	Enabling calling tone may make it easier for the 	modem you are calling to detect that this is a data call 	if the remote modem uses a voice/data/fax 	discriminator.
	S25    5     0-255      1/10 seconds	Delay to DTR.  S25 specifies the delay time threshold 	for which DTR must be active in order to be 	recognized. If 			DTR remains at a state for less than S25/100 	seconds, it is ignored.
	S28   0     0-14           n/a	Desired Line Speed Control Register.S28  contains the 	user's desired line connection speed.  The connection 		speed will be the maximum speed supported by both 		modems not exceeding the speed specified by this 			register.
		Please note the interaction between S28 and &N.
		00 Use the UART divisor latch setting to determine the 	rate to attempt the connection with the remote 	modem.
