Remote Control via PPP
For starting a remote control session via PPP (Point-to-Point Protocol) the radio must be con-
nected via serial cable to a remote station (i.e. PC). To establish the PPP session the above
mentioned settings (see Changing the PPP IP Interface Address) have to be adjusted on the
remote station and finally the PPP connection has to be started.
An additional routing entry (host route) needs to be set on the remote station to reach the
remote control server:
• Dest IP: IP of local Ethernet interface (main IP interface of the radio)
• Netmask: 255.255.255.255 (

host route)
• Gateway IP: remote connection IP of PPP session (provided by radio) = “PPP IP address
of Radio+1”
On a PC this could be the following command line:
route add 192.168.100.2 mask 255.255.255.255 192.168.0.2
with
radio’s local Ethernet IP = 192.168.100.2 and PC’s local PPP address = 192.168.0.2
Additionally, a gateway address must be configured, even if there is no gateway. The gate-
way address, which is by default 0.0.0.0, has to be changed to any unicast address within
the IP subnet of the radio’s Ethernet interface, except .0 and .255 and the radio IP address
itself.
Then remote control can be started by addressing the IP of the radio’s local Ethernet inter-
face.
