Remote Triggering. The PocketWizard PowerMC2 plugs directly into the Einstein so that you can use a PocketWizard to trigger it. If you’re using the PocketWizard FlexTT5 as the commander, the free PocketWizard Utility Software will let you configure it to adjust the Einstein’s power from the camera. On Canon cameras, this is done via Flash Exposure Compensation (FEC). For Nikon cameras, you’ll use the Exposure Compensation dial.

Power Tracking. With a little more advanced setup in the PocketWizard Utility Software, you can set the Einstein to track its power when you change your camera’s exposure settings. If you’re using the standard Pocketwizard Plus IIIe or Plus IVe, you can trigger the strobe unit, but you won’t be able to adjust strobe power from the camera.
