1. How to install the DFM-560E modem?(Back to top)

Here are the installation steps for the modem:

Note: Please uninstall your modem if it was not installed correctly for the first time:
Please go to Start > Settings > Control Panel > Modems > Select the modem and click on Remove.
Please check your Device Manager as well: go to Start > Settings > Control Panel > System > Device Manager > and have a look if there are any Unknown, Unsupported or Other Devices there. Remove them as well as devices with yellow exclamation marks or question marks. Then please do the following:

• Shut down your computer.
• Connect one side of the cable to the modem.
• Connect another side of the cable to your computer's COM 2 port (or COM 1).
• Plug the power supply into the mains and connect the little power plug to the modem.
• Turn the modem on (you will see some red lights flashing on the modem).
• Turn your computer on.
• On start up Windows will detect the modem automatically and will give you a message saying "New Hardware Found".
• Windows will ask you for drivers - please specify the path to the files as "D:\Rockwell\" providing your CD-ROM drive letter is "D" or to path to the files you have downloaded from the Internet.
• Windows may ask you for Windows installation disks - please insert Windows setup CD-ROM if required and specify the path as D:\WIN95 (or D:\WIN98).
• Finish.

The modem should be seen in Device Manager without any exclamation marks or question marks as 56000 bps External Fax Voice Modem.
Please keep in mind that the drivers for your modem are either under root folder or under ROCKWELL folder on the CD. Or if you do not have the SuperVoice CD you can download the drivers from our WEB site: http://www.dlink.com.au/tech/drivers/files/modems/dfm560e.htm. You will need to UNZIP the the files first using WINZIP.

The driver basically consists of two files:
AULMDM1.INF - which is the modem driver;
WAVRSS.INF - which is the wave support driver (for modem) that Windows will ask for immediately after modem driver is loaded.

2. How can I check if the modem is installed properly?(Back to top)

Please go to Start > Settings > Control Panel > Modems > Diagnostics tab
You should see a new modem installed on one of the COM ports (eg. COM2 56000 bps External Fax Voice Modem). It could be COM1 or COM2 depending on your computer.
Select the COM port with your modem, Click on "More Info..." button.
After a while, you will see a window with the results codes - the response from the modem.
If there are no Error messages there, then the modem is installed correctly in your system.

3. How do I connect to the Internet?(Back to top)

After you have installed your modem successfully you can configure your Internet connection. Double-click on My Computer and open Dial-Up Networking. You will see "Make New Connection" icon - double-click on it and follow the prompts. You might need some assistance from your ISP (Internet Service Provider).

If you had another modem installed before, you need to reconfigure your Dial-Up connection to use the new modem. To do that please go to My Computer > Dial Up Networking > right-click on your ISP connection icon and select Properties. Under Connect Using... menu select 56000 bps External Fax Voice Modem. Then click on OK.

4. How to make my connection more stable?(Back to top)

Please make sure that you have got CALL WAITING disabled on your telephone line. If someone calls you while you are connected to the Internet - you will get disonnected eventually. Please contact your telephone company on how to temporarily disable Call Waiting.

Please make sure that you have your modem connected directly to the first telephone socket in your unit/house and there are no other devices (telephone, fax, answering machine) connected to the line before your modem socket. All these devices can be connected to the line which goes out of the TELEPHONE jack of the modem.

Dropouts are usually related to poor line quality. It may happen that the dropouts you are experiencing are related to the fact that the modems are negotiating v.90 protocol and high data transfer speeds and can not handle this speed later on causing disconnections. You can fix this problem by forcing the modem to connect using K56Flex protocol rather than v.90.
To do that please go to Start > Settings > Control Panel > Modems > select your modem > Properties > Connection > Advanced > Extra Settings...

In the Extra Settings field please type the following:

AT+MS=56,1,300,38000

If you will find the connection stable try to increase the speed - change the last number (38000) in the string to 42000. Try it for a couple of days and if the connections will be stable with this string, try 46000 or 48000.

We would not recommend to increase the speed higher than 48000 bps - it is the average speed of 56K modems. With speeds higher than this you may experience frequent disconnections from ISP.

5. Why am I not connecting at 56000 pbs?(Back to top)

It is almost impossible to achieve FULL 56k (it is only a theoretical value). Surveys done in USA indicate that the typical speed of 56K modems is 44k to 50k. Moreover according to FCC, due to electrical power constraints , legally, the max. speed would only be 53kbps (more power is required on the line to achieve 56k, which the FCC forbids).

The actual speed depends on the line quality/condition.
Please note that 56K technology is only 56K download speed. Upload speed is still only 33.6K. This is the limitation of the technology itself. So if you are connecting to another modem (not to your ISP you can only get 33.6K maximum).

When system reports about the speeds like 56000 or 115200 - it is actually the port speed (DTE) not the line speed (DCE). Port speed can be set in Control Panel > Modems > Properties > Maximum speed.
To make Windows to report line speed instead of port speed use ATW1 (or ATW2) command under Start > Settings > Control Panel > Modems > select your modem > Properties > Connection > Advanced > Extra Settings...

In some cases using K56Flex protocol instead of v.90 gives better speeds. Please try this string under Extra Settings:

AT+MS=56,1,300,48000

6. How to make the modem to autoanswer?(Back to top)

If the software that you are using with the modem does not have the ability to set the modem to autoanswer you will need to configure the modem yourself. You will have to use Hyperterminal to enter the command into modem's memory.
(if you do not have Hyperterminal installed please add it by going to Control Panel > Add/Remove Programs > Windows Setup > Communications > Details...)
Please have the modem connected to your computer and ensure that it is working fine. Please go to:
Start > Programs > Accessories > (Communication >) Hyperterminal .... Hyperterm.exe > name the connection "modem" > Connect Using... Select COM1 or COM2 (on which port the modem was assigned) > Bits per second 9600 > OK.
After that try typing ATZ command and press ENTER (you may not see what you are typing). The response from the modem should be OK.
Please type in the following command:

ATS0=3

Note: the list of AT commands is available here: www.dlink.com.au/tech/resources/files/modems/dfm560e.htm

Now can write the all the settings you have made into modem's memory by typing the following AT command and pressing Enter:

AT&W

The response should be "OK"
The modem will now be set to auto-answer after 3 rings.
