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 (IPn4G 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). In the case of this
‘Remote’ being the VIP Series Station, the value in this field should match the
Listening Port of the Access Point (see UDP Point-to-Multipoint (P)).
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).
