You can use an external pulse to trigger the Sync Flash and Dual Level effects. This input is on the Accessory Connector, see Accessory pinout for more information.
- The Rising pulse edge triggers the effect, and is the same as pressing the FLASH button in.
- The Falling pulse edge is the same as releasing the FLASH button.
- The input level can be inverted by selected 'Invert Input Level' from the Advanced > Sync Options menu.
An input voltage from 5V – 24V can be used for trigger signal. The input impedance is 150kΩ.
