Dialin Access
Last updated:

If you are installing an ICON in a remote
location with a regular dial telephone line and there is no Internet access,
you may connect an auto answer modem to serial port 1 on the ICON or install
an "internal" modem in the PC104 stack. When you dial the ICON it will
answer the phone and establish a ppp connection just as though it was an
ISP (Independent Service Provider). These directions are for an external
US Robotics Model 5686 Faxmodem.
First you must connect a PC to your modem
and configure for a fixed baud rate as follows:
-
Set dip switches on the back of the modem
to 1, 2, 4, 5, 6, 7 up (off) and 3 and 8 down (on).
-
Start Hyper Terminal or your serial modem
communication program.
-
Make a new direct connect serial connection
on the serial port to which you connected the modem.
-
Set the baud rate to 115200 for your connection
speed.
-
Type AT and <Enter> and make sure you get
an OK response.
-
Now enter the following command:
-
AT&F1&B1S32=98S0=1&W
Your modem is now ready for connection to
the ICON. Install as follows:
-
Connect the modem to the first serial port
of the ICON with a standard 25 pin male to 9 pin female straight through
RS232 modem cable. These can be purchased at any computer hardware store
or Radio Shack.
-
Set dip switches on the back of the modem
to 2, 3, 5, 6, 7, 8 up (off) and 1 and 4 down (on).
-
Connect the phone line to the RJ11 connector
on the back of the modem.
-
Connect the modem to the power outlet with
the supplied power transformer and turn the modem on.
Before continuing, make sure you have connected
your PC to the ICON and have established local communication as described
in the "ICON Installation" manual. Then connect in programming mode.
-
Make sure you have selected the "Program View"
tab.
-
Click the "System Parameter Config" drop down
list above the programming white space area and slightly off center to
the right.
-
Click the "Connection" entry.
-
Use the drop down list to select "Off" for
the "Serial 1 type" field and click the "Update" button if it is not already
set to off.
-
Use the "Connection Type" drop down list to
select "Modem COM3" and click "OK".
-
Click the "System Parameter Config" drop down
list and select "Password/system".
-
Use the "Watchdog" drop down list to select
"Reset system" and click "OK".
-
This causes the ICON to reset and your web
browser connection to terminate. You may reconnect over ethernet in about
one minute if you wish.
Now, when the phone line is dialed, the ICON
will answer the modem and allow the remote user to connect. You must set
up a "Dialin Networking" connection on the PC that will be used to dial
in to the ICON. For Windows:
-
Follow the directions for your version of
Windows to create a new "Dial-Up Network" connection.
-
For Windows 98 you click "Start", "Programs",
"Accessories", "Communications" and finally "Dial-Up Networking".
-
Double click the "Make New Connection" icon.
-
Enter a name for your connection and select
your configured modem and click "Next".
-
Enter the phone number and click "Next".
-
Then click "Finish".
-
Double click your new connection icon to connect.
-
Enter a user name of "icon".
-
Enter a password of "icon".
-
Then click the "Connect" button.
If all goes well you will be connected to
your remote ICON by modem. Now connect to the ICON in the normal manner
using the same IP address you used for your local PC to ICON ethernet connection.
