Phantom II
© CalAmp 98
6.1 Configuration
IP Protocol Config (continued)
UDP Point-to-Point: In this configuration the Phantom II will send
serial data to a specifically-defined point, using UDP packets. This
same Phantom II will accept UDP packets from that same point.

Remote IP Address
IP address of distant device to which UDP packets
are sent when data received at serial port.
Default:
0.0.0.0

Remote Port
UDP port of distant device mentioned above.
Default:
20001

Listening Port
UDP port which the Phantom II listens to
(monitors). UDP packets received on this port are
forwarded to the
unit’s serial port.
Default: 20001
UDP Point-to-Multipoint (P): This mode is configured on a
Phantom II which is to send multicast UDP packets; typically, the
MASTER in the Phantom II network.
Multicast is a one-to-many
transmission of data over an IP
network. It is an efficient method
of transmitting the same data to
many recipients. The recipients
must be members of the specific
multicast group.
TTL: Time to Live is the number
of hops a packet can travel
before being discarded.
In the context of multicast, a TTL
value of 1 restricts the range of
the packet to the same subnet.

Multicast IP Address
A valid multicast address this unit uses to send
multicast UDP packets upon receiving data from
the serial port. The default value is a good
example of a valid multicast address.
Default:
224.1.1.1

Multicast Port
A UDP port that this Phantom II will send UDP
packets to. The Multipoint (MP - see the UDP
Point-to-Multipoint (MP) description) stations
should be configured to listen to this point in order
to receive multicast packets from this Phantom II.
Default:
20001

Listening Port
The UDP port that this unit receives incoming data
on from multiple remote units.
Default:
20011

Time to Live
Time to live for the multicast packets.
Default:
1 (hop)
