All digis hear the first UI frame and store it. Due to the setting of UIDWAIT, some
stations may wait longer than others to digipeat; hence, when they do, they may have
several frames stored up - for example, the original and a digipeat from another station.
Trace station B as an example. It digipeats the original UI frame from the ―reporting
station,‖ swapping its MYCALL for RELAY (B) and marking it (*), then repeats a frame
from A and one from C, and, finally, repeats two more (from A,C and C,A) —a total of
five! Note that each repeater digis five times so the total number of digipeated packets
is 15!
Configuring Three Digis Using the UIFLOOD Command
Here, three digis, with MYCALLs of A, B, and C, are configured with an alias of WIDE,
and UIDWAIT is set ON. For example station A‘s UIFLOOD call is set as follows:
cmd: UIFLOOD wide,30,ID
The reporting station path is then set to GPS via WIDE4-4, and a UI packet is launched.
Any one of the stations monitoring will then display the resulting action as follows:
WØXI>GPS,WIDE4-4: <UI>:5
WØXI>GPS,A*,WIDE4-3: <UI>:5
WØXI>GPS,B*,WIDE4-3: <UI>:5
WØXI>GPS,C*,WIDE4-3: <UI>:5
Note that all three digis see the UI frame addressed to GPS via WIDE4-4. They then, in
turn digipeat that frame, inserting and marking as digipeated (*) their MYCALL, and
include the new to-be-digipeated and decremented field of WIDE4-3. Note that each digi
hears the UI frames repeated by the others but does not digipeat those in turn since a
timeout of 30 seconds was specified by the UIFLOOD command. See the command
specification for details.
Configuring Digis Using the UITRACE Command
Here, digipeaters A, B, C, and D are set with UITRACE trace, 30. Digipeater B then
launches a UI frame using UN GPS via TRACE4-4. The following results:
B>GPS,TRACE4-4/1<UI>:QWER
B>GPS,A*,TRACE4-3/1:<UI>:QWER
B>GPS,D*,TRACE4-3/1:<UI>:QWER
B>GPS,C*,TRACE4-3/1:<UI>:QWER
Stations A, D, and C hear B and digipeat the UI frame, inserting their MYCALL and
decrementing the SSID of trace. A does not re-digipeat D or C because its ―n‖ timer is
set to 30 seconds, that is, it will not repeat any frame again within that time that includes
the same source or destination and data (in this case QWER).
