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.
See Figure 2 below for a wiring diagram for the RCA connectors.

Activating Relays
Some applications require activating a relay to enable (or disable) a “load”. Relays allow
StopShot to turn on/off a variety of AC and DC devices.
CAUTION:
Care should be taken when wiring the flash sequencer to control AC or high-
voltage DC as a mistake in wiring the relay could cause damage to the unit and other connected
devices.
See Figure 3 below as an example of wiring the sequencer to control a 12V DC relay.
