Four COM port selection IRQ's 3,4,5,6,7 ******************************** DSVD INSTALLATION ******************************** CONFIGURING THE COM PORT AND IRQ LEVELS A COM ( communication ) port is used by the PC to select the I/O address of a serial communication device (such as a modem or a mouse). There are four COM ports to select from, but only one device can be assigned to each COM port. Interrupt request lines (IRQs) enable the PC peripheral devices (such as a modem or a printer) to signal the CPU when they need attention. Normally COM1/COM3 use interrupt request level 4 (IRQ4), and COM2/COM4 use interrupt request level 3 (IRQ3). Communication port base address and IRQ selection on the target board is done either through jumper configuration or using the PnP ( plug'n'play) device which is a population option. Tables 1 and 2 show how to configure the COM port and the Interrupt level selections, respectively. Table 1.

Install the Target Board into the PC, referring to your computer's installation procedure.2. Connect the phone line from the wall to the jack labeled "LINE" or "WALL" using a standard RJ11 type telephone cord.3. Connect the telephone to the jack labeled "PHONE" using a standard RJ11 type telephone cord. 4. Connect the electret microphone to the jack labeled "MIC". 5. Connect an amplified speaker to the jack labeled "HDSET". A Headset unit can be connected to the modem's MIC and HDSET jacks as well . If an external speaker/headset will not be used, connect a shunt to J26 and J27 to power the on-board sounducer. 7. The target board is capable of supporting full-duplex speakerphone or telephone emulation mode. The board is configured at the factory for the speakerphone mode by shunting J23 and J25. To support telephone emulation operation, shunt J23 and J24. OPERATION IN DSVD MODE ====================== DSVD Modes Operation in DSVD mode allows data transfer and voice conversation to occur simultaneously during a data connection. On a DSVD call, either a telephone or a headset can be used as the voice interface. Both local and remote modems need to have Rockwell DigiTalk tm DSVD technology to support the simultaneous voice and data function. There are two methods to transition to DSVD mode: 1. Data mode to DSVD 2. Analog voice mode to DSVD DATA MODE TO DSVD TRANSITION ============================ This method allows the user to establish a data connection first and transition to DSVD by picking up the handset or by using the headset. 1. Issue AT-SSE=1 command on both modems through terminal mode or include it as part of the initialization string in the communication software. 2. One user picks up the handset ( generates ring and ring back ). 3. Once the other user picks up handset DSVD is established. 4. DSVD is terminated when either side hang up handset. DSVD can be initiated if either side picks up the handset again. ANALOG VOICE MODE TO DSVD TRANSITION ==================================== This method allows the user to establish an analog voice call first and transition to DSVD by initiating a data connection. 1. Issue AT-SSE=1 command on both modems through terminal mode or include it as part of the initialization string in the communication software. 2. Establish analog phone connection. ( Make sure both modems have ATS=0 to disable auto answer. ) 3. When one user issues ATD this modem will initiate handshake and handsets will be muted. 4. Once data connection has been completed the users will be in DSVD state. In DSVD state, both voice and data communication can take place simultaneously. 5. DSVD is terminated when either side hang up handset. DSVD can be initiated if either side picks up handset again. DSVD HEADSET MODE ================= The DSVD modem allows the use of a headset (instead of the handset) for voice communication during DSVD mode. 1. The command AT#CLS=5 must be issued after the AT-SSE=1 command in terminal mode or in the initialization string on the communication software. 2. Once a data connection is made the modem in the headset mode will immediately initiate the DSVD connection by ringing the remote user. 3. Local handset transitions are ignored in this mode. 4. If the remote user has a handset the state of the remote handset will control state transitions. if the remote user puts down their handset the modems are in data mode and if the remote modem picks up the handset DSVD is established. 5. If the remote modem is also in headset mode, the modems are always in DSVD mode unless one of the parties issue a +++ to go to command mode ( no audio during command mode ) followed by AT#VLS=0 and then back on-line with an ATO. During this time, the DSVD mode is terminated and the headset in no longer operation. To return to headset mode, issue a +++, followed by AT#VLS=5 and then go back on-line with an ATO. 6. No simulated busy or ring tones will be played to the modem in the headset mode. OPERATION IN SPEAKERPHONE MODE ============================== OPERATION WITH COMMUNICATION SOFTWARE The full-duplex speakerphone operation can be used by running a communication software application which supports the Rockwell Speakerphone function. Follow the instructions of the respective application package. Alternatively, speakerphone operation can be used by manually issuing AT command to the modem. Be sure a shunt connects J25 and J23 to support the speakerphone mode. MANUAL OPERATION USING TERMINAL MODE ==================================== Origination a Voice Call in Speakerphone Mode 1. Invoke the terminal mode in your communication package. -Install MegaConnect software then click on MegaConnect Terminal. -At MegaConnect Terminal screen click on Options and select Serial Port... -Select the right Com Port according to hardware setup. 2. Enter AT and make sure that OK is returned. Enter AT&F to reset modem configurations to default values. All instructions to the modem are communicated through AT commands. For example, ATD is the AT command for the modem to dial; all AT commands start with the "AT" characters. 3. Enter AT#CLS=8#VRN=0#VLS=6 and press the return key. The modem should respond with "OK". This will initialize the modem for speakerphone mode. Answering a Voice Call in Speakerphone Mode 1. Invoke the terminal mode in your communications package. 2. Enter AT and make sure that "OK" is returned. Enter AT&F to reset modem configuration default values. 3. Enter AT#CLS=8VRN=0#VLS=6S0=0 and press the return key. The modem should respond with OK. This will initialize the modem for speakerphone mode. 4. To answer a call in speakerphone mode upon receipt of a RING message, enter ATA. The modem will report VCON to indicate speakerphone is on. 5. To hang up, issue ATH. Mega Connect Terminal. ====================== Install Mega Connect Lite and click on MegaConnect Terminal. At MegaConnect Terminal Untiltiled click on Options... . Select the Serial Port and select your Com Port and click "OK". Click on Options again and select Default Settings. At Default Settings click on 57600bps and click on feild of Additional Initialization and input &C1&D2S7=75 and click "OK". At black screen you see cusor flashing type AT and press Enter key on your key board. The modem should respond 'OK". Now you are in the MegaConnect Terminal Mode. End ===Download Driver Pack
