1. Safety Instructions
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death
or serious injury.
Follow all CAUTION notices to reduce the risk of personal injury, prevent damage to the
StopShot module, accessories, and devices (cameras, flashes, etc). Failure to follow all CAUTION
notices may void your warranty. CAUTION may also indicate a potentially hazardous situation
which, if not avoided, may result in personal injury.
The safety alert symbol precedes a general CAUTION or WARNING statement.
The electrical hazard symbol precedes an electric shock hazard CAUTION or WARNING
statement.
2. Getting Started
2.1 Package contents
The latest version of this manual is available at
Your Flash Sequencer package contains the following:
1. Flash Sequencer Module (1)
2. 6 ft - 3.5mm M/M Cable
3. (2) - 6 ft – RCA M/M Cable
4. PC→RCA Cable
You will need one PC→RCA cable and one 6 ft RCA cable for each flash that you intend to use with the
sequencer.
2.2 Connections
http://www.cognisys-inc.com.
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
allows the sequencer to draw power from StopShot.

Sensor
(Beam, Vibe, etc.)
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.

WARNING: High voltage flashes should NOT be connected to the sequencer or any of its associated
adapters/connectors/cables. Doing so could expose you to dangerously high voltages resulting in
serious injury or death. All new flashes on the market do not expose high voltage on the hot-shoe.
These are the flashes intended for use with the sequencer. Please visit our web-site at
http://www.cognisys-inc.com for a list of low-voltage flashes, or contact us via e-mail at:
support@cognisys-inc.com.
CAUTION: Do not use “Y” adapters for the trigger outputs to connect more than three devices.
Some devices generate significant transients (like solenoids) that may damage sensitive equipment such
as cameras and flashes. The sequencer is protected from these transients but other electronics (such as
flashes and cameras) may not be. 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.
