4.0 Configuration
IP Protocol Config (Continued…)
TCP Client/Server:
In this mode, the IPnXGii will be a combined TCP Client and Server, meaning that it
can both initiate and serve TCP connection (session) requests. Refer to the TCP Client and TCP Server
descriptions and settings described previously as all information, combined, is applicable to this mode.
UDP Point-to-Point:
In this configuration the IPnXGii will send serial data to a specifically-defined point,
using UDP packets. This same IPnXGii 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 IP Series 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 an IPnXGii which is to send multicast UDP
packets; typically, the Access Point in the IPnXGii network.
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 IP Series 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 IPnXGii unit.
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)
A UDP or TCP port is an
application end-point. The IP
address identifies the device
and, as an extension of the IP
address, the port essentially
‘fine tunes’ where the data is
to go ‘within the device’.
Be careful to select a port
number that is not
predetermined to be
associated with another
application type, e.g. HTTP
uses port 80.
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 me 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.
