Step 3
RipEX2 C and RipEX2 A send the received packet to their
COM ports.
Packet is addressed to RTU C, so only RTU C responds.
RipEX2 A is set as a repeater, so it retransmits the packet
on Radio channel. Packet is received by all RipEX2 units.
Step 4
RipEX2 B sends repeated packet to its COM.
RTU B does not react, because the packet is addressed
to RTU C.
RipEX2 C and RipEX2 FEP do not send the repeated
packet to their COM ports, because it has already been
sent (RipEX2 C) or received (RipEX2 FEP) on their COM
(anti-duplication mechanism).
RTU C sends the reply packet.
Step 5
RipEX2 C broadcasts the reply packet from RTU C on
Radio channel.
Packet is received by RipEX2 A and RipEX2 FEP.
Step 6
RipEX2 FEP sends the packet (the reply from RTU C) to
FEP through COM.
RipEX2 A sends this packet to RTU A. RTU A does not
react, because the packet is addressed to FEP.
RipEX2 A repeats the packet on Radio channel.
All RipEX2 units receive the packet.
Step 7
RipEX2 B sends repeated packet to its COM.
RTU B does not react, because the packet is addressed
to FEP.
RipEX2 C and RipEX2 FEP units do not send the repeated
packet to their COM ports, because it has been handled
already.
FEP processes the reply from RTU C and polling cycle
continues…
