The data being sent via ethernet is packaged into UDP packets
and a separate copy is sent to each IP address in the EtherPoll’s
IP address list.
Point - to - Point Mode
EtherPolls configured for Point-to-Point mode function the
same. The only difference between the “normal” operation and
point-to-point is the number of IP addresses in the IP address
list. For point-to-point operation, there is only one address in
the list (the other unit’s).
Broadcast Mode
Broadcast mode is also identical to “normal” mode. There is
simply no polling taking place over the network.
Transmit Conditions
The EtherPoll will transmit an ethernet packet of data whenever
one of the following conditions is met…
•
Timer is up. In Timer Mode, a free running clock triggers
a transmission when it ticks if there is data in the buffer.
•
Idle time is up. In Idle Timeout mode, a (configured) time
period elapses with no incoming data if there is data in the
buffer.
•
Transmit Buffer full.
•
LT Character is encountered if Line Terminal Function is
ON.
