UDP Echo Client/Server

UDP Echo n
When enabled, UDP Echo generates UDP packets that contain the unit serial number and ID, and
transmits them to the speci
fi
ed IP address and port at the con
fi
gured interval. When the unit receives
a UDP packet at a local port con
fi
gured for UDP echo, it will “echo” the packet back to the sender.
There may be more than one UDP echo instance available on the unit. Instance 0 is used when
specifying the local port to listen on.

Destination IP address:
The IP address that UDP echo packets should be sent to. If this parameter is left blank, UDP Echo is
disabled.
Destination port:
The destination port UDP echo packets should be sent to.
Local port:
The local port on the unit that should listen for UDP echo packets. If any UDP packets are sent to this
port, the unit will send a copy back to the IP address and port they were sent from.
Echo request interval (s):
This parameter speci
fi
es the interval at which the unit will send UDP echo packets to the
Destination
IP address

Use routing code to determine echo interface:
When this parameter is set to “No”, the interface used to send UDP echo packets will be speci
fi
ed
in the
Interface
and
Interface #
parameters below. In this instance, the interface must already be
connected for the packets to be sent. When set to “Yes”, the routing code is used to determine the
best interface to send the UDP echo packets on. The interface will be connected if necessary before
the packets are sent.
Only send when interface is in service:
When this parameter is set to “Yes”, and

is set to “No”, UDP packets will not be sent if the

is out of
service.
Exclude data from UDP packet:
When this parameter is set to “No”, UDP echo packets will contain the unit’s serial number and
ID in textual form. When set to “Yes”, the packet will only contain a single byte of data of value 0.
This keeps the size of the packets down, which is useful if the interface has high data charges (e.g.
GPRS).
Interface:
This parameter speci
