Example Two.
In the second example we can see chart one shows the radio is transmitting a large amount of data in the last half of the
sixty second scan. We can configure the second chart to read specific information about the radio link which can help us
determine what shows that the radio is holding off from
transmitting around 36% of the time which is a clear indication that the radio frequency is busy. The other two charts
show that it is not transmitting many acknowledgements but is send a number of first attempts indicating that it is
initiating the increase in communications.
Network Diagnostics 4.6
Network Diagnostics allows you to check the communications path to other modules within the system.
Ping
Ping is a standard Network instruction that sends out a small data probe to the IP address configured letting you know if
you have a communication path or not.
You will receive a response for each Ping, which will show a packet size, IP Address, Sequence number and a time in
milliseconds.
Followed by a summary showing the number of packets transmitted, the number of packets received, any lost packets
and the Minimum, Average and Maximum Ping times in milliseconds.
A Ping can be done on either the Radio Network or Ethernet Network. The ping command will automatically select the
correct network interface according to the address selected.
