Q&A’s
- Whilst you can use the ST-III to trigger these lights, you can’t remotely control the power of those flashes. In order to do that, you will require the PiXAPRO PRO AC Trigger set
- The ST-III triggers should work with no problems, though you would require a ST-III receiver for each of your Li-Ion TTL speedlites. You can also control the power of your Li-Ion TTL speedlites remotely.
- The ST-III Receivers are cross compatible with the Pro AC 2.4GHz triggers, and also the ECO2.4 Triggers. However, they are not compatible with the ST-II transceivers, or the older 433MHz versions of the Pro AC or the ST-I Triggers
- To use the Multi-Flash Setting with your ST-III Flash Triggers, please follow these steps:
- To Set-up multi-flash function on your ST-III trigger set, keep pressing the
button until the TTL and M icons are not displayed on the LCD (As shown in the photo below). Once that has been done, press and hold the Button to enter multi flash setting submenu. 
- Once in the Multi-Flash submenu, two lines displayed as T (for the amount of flashes) and H (for the flash frequency in Hz) should appear as shown in the photo below.
- Press the
Button to make the “T” value blink. Once blinking, you are able to set the amount of flashes according to your needs by using the wheel. - Press the
Button again to change the “H” value. - Once your Multi-Flash settings have been set, Press the
Button to exit the Multi-Flash settings screen - In the multi flash setting submenu, press the
Button to return to main menu. Multi Flash Settings (Output Value) - In the multi flash (TTL and M icon are not displayed), press the
Button to set the current group. - In multi flash mode, you will be unable to exceed 1/4 power as the flash units can’t do multi-flash with output settings higher than ¼ power.
- In the multi flash (TTL and M icon are not displayed), press the
- To Set-up multi-flash function on your ST-III trigger set, keep pressing the
- No, that doesn't work unfortunately. The master flash requires some kind of physical connection to the camera’s hot shoe in order for that to work. You can either sit the master flash directly on the camera’s hot shoe, or use an off-camera TTL flash cord.
The only way around it would be to use one of the following solutions:
- Place a speedlite, set to master mode on top the ST-III trigger’s hot shoe, whilst the ST-III trigger is on camera.
- Purchase another ST-III receiver for the other speedlite.
- Purchase an Off Camera TTL cable for the Master flash to sit on.
