Figure 4-6 Host mode configuration (UDP mode)
1) Operations
If a remote host sends a UDP datagram to the one of UDP
Local port
of the Pro Series, Pro Series first
checks whether it is from one of the hosts configured on
remote host configuration.
If the remote host
is one of the hosts configured on
remote host configuration
, then Pro Series transfers the data through
the serial port. Otherwise, the Pro Series discards the incoming UDP datagram. But user can force Pro
Series accept all incoming UDP datagram regardless
remote host configuration
by setting
Accept UDP
datagram from unlisted remote host
parameter as ‘Yes’. If there is any incoming data from the serial
port, the Pro Series transfers the data to the remote host defined on
remote host configuration
. If the
remote port is not opened, the Pro Series will not transfer the data.
