3.5.5 Ping
The ping page can be used to check for connectivity between devices. It
is especially useful to ping the receiving data port from the IP
transmitter to see if the receiver can be reached. Figure 14 shows the
Ping page with its parameters.

Figure 14 Ping tab
IP destination: Enter the IP address to check for contact here. The ping
messages will be routed to the matching Ethernet port, either data or
management, or to the port configured as default management
interface if the specified IP address does not match either of the two
sub-nets. Remark that if you are pinging between data interfaces, the
‘allow ping response’ option on the network page advanced tab (see ch
3.5.1) must be enabled on both the transmitter and the receiver.
TTL (Time to live): Enter the Time to Live value for the ping messages
here. The time to live value is a field in the IP protocol header that is
decremented once for each router that the diagram passes. When the
count reaches 0, the diagram is discarded. You can use this to check
the number of routers from the transmitter to the receiver by starting
with a low value and increment it until answers are received. TTL is
also specified for each data channel on the IP transmitter, and must be
high enough to reach the receiver. Values range from 1 to 255.
Ping count: The number of messages to send. The messages are
transmitted with an interval of about 1 second.
Start: Press this button to start the ping sequence configured above.
The status of the ping sequence is displayed in the status frame at the
right side. Status values are reset on pressing the start button. After
