• If the Master Sync Out is Acti v e High, then the Slave Sync In must be set for Rising Edge. If
Master Sync Out is Acti v e Low, then the Slave Sync In must be set for Falling Edge.
NOTE: For the “common” setup as well as for variations li s ted below, always make sure that the Post
Trigger portion of the r ecording tim e for the Master camera is equal to or greater than each of the
Slave cameras. This is important because Sync Out pulses cease with the completion of th e capture, so
the Master camera must continue r ecording until all Sl a ve cameras complete their recordings.
Parameters that a ff ect post trigger recording tim e include: Trigger position Resolution Bit depth,
base internal Memory (camera model), Frame rate.
Variations on Ma
s ter/Slave:
• Use a slower frame rate for one or more of the slave cameras by using a Rate Divisor in the
Sync-In setup. (Make sure to make allowance for the extended tim e per the note above.)
• Extend the overall record tim e by adjusting the tri g ger position or all cameras. For example, set
the Master to a Start trigger, the fi rs t Slave to 10%, the second Slave to 50%, etc. This would
also be used if the subject is progressing through the di ff erent cameras’ fi e lds of view, as a
runner running by each camera in sequence.
• Run cameras out of phase with each other. Higher e ff ecti e frame rates can be simulated by
running cameras out of phase with each other. This is usually done by using Duty Cycle in Sync
Out, for example: if you set the Duty Cycle for 50% and invert the signal, the next camera in line
will run 180 degrees out of sync.
