Chapter Three Configuration
Man_455U-D Rev 3.01 Page 39
The first ring of repeaters (units 14 and 15) need to be configured as below:
The “Repeat Messages to address 0” box is selected to allow these units to repeat the
broadcast messages on.
The “Copy Messages … serial port” box is selected to pass any broadcast radio messages
it receives to its host device.
The “Hops” box indicates the number of hops that the message has to go through before
this unit will repeat the broadcast message. This is to prevent units repeating messages in
the wrong sequence. In this case, “Hops” is set to 1 - repeater after the first hop.
Note that the address path for return messages is <1>.
The second ring of repeaters (units 21 and 22) need to be configured as above:
The “Hops” box is set to 2 - repeater after the second hop. If unit 21 hears a weak
message from unit 1 on the first hop, it will not repeat it.
Note that the address path for return messages is <14,1>.
The last ring of units (units 36 and 37) need to be configured as above:
The “Repeat Messages to address 0” box is not selected as these units are not required to
act as repeaters..
The “Copy Messages … serial port” box is selected to pass any broadcast radio messages
it receives to its host device.
The “Hops” box is set to 3 - this means that it will only accept messages on the third
hop. If it hears a weak message transmitted from unit 1 or 14, it will ignore it.
