29 BOOM BOX 3 Dynamite Controller
9. BB3/UE3 Encoder Operation
The Boom Box 3 can be placed into the BB3/UE3 Encoder mode by changing the operating mode
with the Source Control F3 software or the SourceLink v.22 and newer software. Then the main
encoder parameters are changed by Source Control F3 program or the SourceLink v.22 program,
Parameters and Encoder Parameters. The BB3/UE3 Encoder mode does encoder operation
differently from the original BB3Encoder mode above. The BB3/UE3 Encoder mode operates like
the UE3.
When the BB3 is in BB3/UE3 Encoder operation, SourceLink needs to be set to UE3.
Encoder/Decoders -> Connections -> Encoder/Decoder… Universal Encoder 3
The Boom Box 3 firmware needs to be 15.23 or newer in the Boom Box 3 encoder and decoder for
this functionality to work.
9.1.1 Fire Sequence – 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.22 or v.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.
• After the Shot is fired the Encoder receives the Shot Status Report message from the
Decoder. The time when the message is received determines when the timing pulses will
occur.
• The Encoder display will show ‘PFS Rx !!’ when the decoder post report is received.
• The Encoder generates reference pulses at 1, 1.5 and 2 seconds. These pulses should align
with the timing pulses generated from the Decoder’s Shot Status Report.
