Changing the PPP IP Interface Address
Apart from the Ethernet and air IP interface the
radio offers a third IP interface, the PPP IP in-
terface (point-to-point protocol). It allows a se-
rial connection from a computer to the radio by
means of the point-to-point protocol (PPP).
The PPP IP interface has a fixed network
mask of 255.255.255.0, but its IP address can
be configured here. A computer establishing a
PPP connection receives its IP address from
the radio, which is always "PPP IP address of
Radio" + 1.
The radio must have PPP enabled in its IP port
configuration, and the following settings apply
for the remote endpoint:
• The baudrate must be set to the same val-
ue as configured in the radio. Possible set-
tings are: 2400 bit/s, 9600 bit/s, 19200 bit/
s and 115200 bit/s.
• No hardware flow control
• IP header compression may be enabled
• Supported authentication protocols are
PAP and CHAP
• User name/password: vxPPPClient/vxPP-
PClient
