31 BOOM BOX 3 Dynamite Controller
9.2.1 BB3/UE3 Repeater Encoder Operation
The Boom Box 3 system can be used in an BB3/UE3 Repeater operation. This operation is used
when the radio reception from the Encoder to the Decoder requires a radio repeater. This is
typically a problem in very mountainous areas.
The BB3/UE3 repeater operation requires one Boom Box 3 in BB3/UE3 Encoder with Repeater ID
set to any number above zero. Another Boom Box 3 decoder with firmware 15.23 or later to be the
repeating decoder and a Boom Box 3 decoder with firmware 15.23 for the shooting decoder.
• The BB3/UE3 Repeater Encoder operation is set by making the BB3 Sequence, Repeater
ID to any number besides 0. The Repeater ID must match a BB3 decoder unit ID that is in
the radio network. The Source Control F3 program version 3.22 or version 3.21 can be
used to setup the BB3 sequence table.
• The BB3/UE3 Encoder requires the Start Delay to be 1100 or more for repeater
functionality to work.
• The BB3/UE3 Encoder Repeater operation can also be setup with SourceLink v.22 and
newer within the Group entry Repeater ID.
9.2.2 Fire Sequence – BB3/UE3 Repeater Encoder – Following sequence occurs.
• The fire sequence can be started multiple ways.
o Using Source Control F3. Encoder Parameters, Recording System type is any of
the settings. Start Mode set to Start Message. Source Control F3 can fire the
Boom Box 3 BB3/UE3 encoder.
o Encoder Parameters, Recording System type is Sercel. Place the Sercel recording
system in SGDS dynamite mode. Setup the BB3/UE3 sequence table with Source
Control F3 v.3.22 or v.3.21. The Sercel recording system can now send the
sequence RTI message that tells the Boom Box 3 encoder which sequence to use to
make the Start Code.
▪ Source Control F3: Start Mode set to Start Message. SourceLink v22 or
newer: Start Mode set to Start on Shot Message (Source Link). The same
Sercel sequence (fire) message will fire the Boom Box 3 encoder.
▪ Source Control F3: Start Mode set to Pulse Falling Edge. SourceLink
v.22+: Start Mode set to Start on External Pulse Falling Edge. The Sercel
sequence (fire) message must be received. Then the BB3 remote start line
must be toggled for the BB3 encoder to send the radio start code.
o Using SourceLink v.22+. Encoder Parameters, Recording System Type –
SourceLink. Start Mode: Start on Shot Message (Source Link).
• The Encoder then sends the Repeater Start Code Radio transmission to the repeater unit.
o Source Control F3 program or SourceLink v.22+ program, Encoder Parameters,
Auto Zero Time not selected. Timing of the time break is determined by Start
Delay and Zero Time Adjust entries.
o Source Control F3 program or SourceLink v.22+ program, Encoder Parameters,
Auto Zero Time selected. GPS start time is in the Start Code Radio message and
used to fire the shot. The time break timing is dependent on the Start Delay.
• The Encoder then issues the Time Break at the end of the Encoder Start Delay Time. The
time break signal should occur while the Shot is being fired by the Decoder Unit.
• The Encoder generates reference pulses at 1, 1.5, 2, 2.5, 3, and 3.5 seconds. These pulses
should align with the timing pulses generated from the Decoder’s repeated Shot Status
Report.
