    2.2 Connections To connect the flash sequencer to StopShot use the included 3.5mm cable and connect one end to the jack labeled “Sensor” on StopShot and the other end of the cable to the “StopShot” jack on the sequencer. Sensors traditionally inserted into StopShot will now be plugged into the sequencer. This...

  • Page 4: Figure 1 - Typical Connection Diagram

    The included six foot RCA cable should be plugged into the desired StopShot trigger output and then be connected to the sequencer’s “Input” jack. StopShot provides the timing signals required by the sequencer. PC to RCA cables coupled with a six foot RCA cable are then attached to the sequencers “Output” jacks. See Figure 1 below for a typical connection diagram.
  • Page 5 It is acceptable to use a “Y” adapter to connect more than one device to a trigger output as long as the devices are similar. If you have any questions or concerns about device compatibility, please contact us at: support@cognisys-inc.com.

  • Page 6: Operation

    3. Operation 3.1 Overview The Flash Sequencer enables StopShot to expand its output capability. StopShot can generate multiple output pulses for each of its three trigger outputs. When coupled with the sequencer, up to three variable length pulses can be generated and up to 1000 fixed length pulses! What does this mean? Each pulse can activate a flash, water valve, or other device.
  • Page 7 # Pulse: The number of pulses (“# Pulse”) may be set to a value greater than one if multiple trigger output pulses are required. This may be used to generate multiple events (firing multiple flashes). If this value is set to one then each “input” to StopShot would cause the sequencer to advance to the next output.
  • Page 8 Toff2: “Toff2” is the duration the second output pulse remains off following “Pulse2”. Pulse3+: If “# Pulse” is three or greater the value of “Pulse3+” will control the on time of the trigger output. It functions similarly to “Pulse2” but controls the third and all future pulses. “# Pulse” must be set to a value of three or greater for this to have any effect.

    “Blank” is set to at least 50ms. 3.3 Indicators The LED lights on the side of the flash sequencer below the “Active” text indicate which output will fire next. Upon applying power, the first indicator will be illuminated showing that “Output 1”...

  • Page 10: Microphone Usage

    “Output 1”. 3.5 Microphone Usage A microphone may still be used with the flash sequencer. The flash sequencer will still need to draw power from StopShot via the “Sensor” connection. When using a microphone, plug it into the “Mic”...

  • Page 11: Activating Relays

    As with all RCA jacks the outside connector is ground. The flash sequencer’s outputs are “Low Side Drivers” (switches in ground). This means that when a output fires, it connects the center conductor of the RCA jack to the outside connector (ground) to draw current through the center conductor.

    Blanking time not set MUST set the blanking time to a minimum of 50ms. If you cannot resolve a problem with your flash sequencer, please contact us at support@cognisys-inc.com. We want to make sure that you are completely satisfied with our product.
