Cyber Commander™ controls and displays virtually every parameter of a complex studio flash setup of up to 16 light units, including the relative flashpower and modeling lamp brightness of all of the lights, from 1.56 to 6400 Ws per light. For each Paul C. Buff™ light connected, it provides an exact digital readout of the flash wattseconds, t.1 flash duration, color temperature, modeling watts, and the relative flashpower using the European standard numerical 0 to 10 scale (automatically adjusting as changes are made in output). Additionally, it displays the actual camera f-stop (in whole f-stops) of each light (or of all lights or of any particular group of lights) from a built-in high accuracy flashmeter that allows setting ISO and exposure time and exact calibration from your lights to your camera.
Cyber Commander™ allows control of parameters from the camera position, including the status of recycle beepers, slaves, modeling lamps, and even power adjustment. It enables manual bracketing of individual lights or a group of lights in precise 1/10f digital steps, while automatically updating the meter reading and power levels. For setups containing lights with different wattsecond ratings and model lamp wattages, the Cyber Commander™ will adjust proportionally, allowing you to maintain deadly accurate what-you-see-is-what-you-get (WYSIWYG) preview.

The PowerMC2 Transceiver Module enables remote power control of Einstein™ flashes using PocketWizard® ControlTL® technology. With a MiniTT1® Transmitter or FlexTT5® Transceiver on your camera and a PowerMC2 plugged into your Einstein™ E640 flash, you can adjust the flash power settings directly from the camera position. Add the AC3 ZoneController® and you can control three different zones of lights in 1/3-stop increments with up to a six-stop range. The system additionally allows use of PocketWizard® features such as HyperSync and Optimized Rear Curtain Sync for maximum control of your lighting
