4.0 Configuration
IP Protocol Config (Continued…)
UDP Point-to-Multipoint (MP): This protocol is selected on the units which are to receive multicast UDP
packets, typically the Remote units. See the previous description of UDP Point-to-Multipoint (P).
 Remote IP Address
The IP address of a distant device (IPnXGii or, for example, a PC) to which the unit sends
UDP packets of data received on the serial port. Most often this is the IP address of the
Access Point.
Default: 0.0.0.0
 Remote Port
The UDP port associated with the Remote IP Address (above).
Default: 20011
 Multicast IP Address
A valid MULTICAST address that this unit will use to receive multicast UDP packets sent by a
UDP Point-to-Multipoint (P) unit. Note that the default value for this field matches the default
Multicast IP Address of the UDP Point-to-Multipoint (P) configuration described on the
previous page.
Default: 224.1.1.1
 Multicast Port
The UDP port that this unit will use, along with the Multicast IP Address detailed above, to
receive the multicast UDP packets sent by the UDP Point-to-Multipoint (P) unit.
Default: 20001
UDP Multipoint-to-Multipoint
 Multicast IP Address
A valid multicast address the unit will use to send multicast UDP packets upon receiving
them at its serial port.
Default: 224.1.1.1
 Multicast Port
UDP port that the packets are sent to. Multipoint stations should be configured to listen
to this port in order to receive multicast packets.
Default: 20011
 Time to Live
Time to live for the multicast packets.
Default: 1 (hop)
 Listening Multicast IP Address
A valid multicast address the unit is to listen to receive multicast UDP packets sent by
another UDP Multipoint-to-Multipoint unit.
Default: 224.1.1.1
 Listening Multicast Port
UDP port that the unit will listen to for multicast UDP packets sent by another UDP
Multipoint-to-Multipoint unit.
Default: 20011
In a Point-to-Multipoint (PMP)
network topology which is to
utilize UDP multicast, typically
the MASTER would be
configured as ’(P)’ (the
POINT) and the REMOTES
would be configured as
’(MP)’ (the MULTIPOINTS).
