We have configured RTU #5 to act as the store and forward unit between Controller Unit #0
and RTU #150. If Controller Unit #0 tries to poll RTU #10 (a fake address for RTU #150),
the transmissions listed in Table 6 will occur.

Description
No. 1
#0
#10
Controller Unit #0 polls RTU #10.
No. 2
#5
#150
RTU #5 has been configured in Slot #1 to recognize
and re-send all transmissions of 0-to-10 as 5-to-150.
No. 3
#150
#5
RTU #150 receives the poll from RTU #5 and sends
its response back to RTU #5.
No. 4
#10
#0
RTU has been configured in Slot #2 to recognize and
re-send all transmissions of 150-to-5 as 10-to-0. This
completes the cycle.
Note
Enter the ID of the out-of-range RTU higher than the largest ID of the in-range
RTUs. Set the Controller address in the out-of-range RTU to its store and forward
unit. This is done in the Co{N}troller Address section of the main menu.
