Server IP / Client IP
When a user dials into the AdderLink IP Gold via a modem or ISDN adapter, the
AdderLink IP Gold sets up a temporary two-device network using PPP (Point to
Point Protocol). For this purpose, both devices must have ‘dummy’ IP addresses
so that they can communicate correctly. These two addresses can be almost
anythingexpressedinthequadoctetformat(i.e.192.168.3.1.).However,itis
advisable not to make them the same as the real IP addresses used by either the
remote system or the AdderLink IP Gold.
Baud Rate
This option configures the speed of the serial connection between the AdderLink
IP Gold and a connected modem or ISDN terminal adapter. The default setting is
115200.Theothercommunicationsettingsarexedas:Noparity,8bitword,1
stop bit.
Init String
The codes entered here are used to prepare the connected modem or ISDN
terminal adapter for use with the AdderLink IP Gold. The default code is
a Hayes-compatible string to configure auto answer mode and would be
understood by the vast majority of modem/ISDN devices. The code is sent when
the AdderLink IP Gold is first switched on or whenever the Initialize button is
clicked.
Initialize Port
When selected, this option sends the characters entered in the ‘Init string’ field
to the connected modem or ISDN terminal adapter.
Restore Defaults
When selected, this option resets the ‘Baud rate’ and ‘Init string’ values to their
original default settings.
