2014 Safety Notice
|FEBRUARY 2014 SAFETY NOTICE FOR CURRENT POWERMC2 OWNERS:
NOTE: This message was first sent out in February 2014. If you purchased your PowerMC2 radios after that point, as new units from an authorized dealer or distributor, please click here to continue to the PowerMC2 Wiki page.
We have identified a potentially hazardous issue with the PocketWizard® PowerMC2 receiver when used in combination with the Paul C. Buff Einstein™ E640 flash units, especially the CE/433 MHz version sold in Europe. You may have received a previous message from Paul C. Buff, Inc. regarding this issue.
In rare circumstances, if the PowerMC2 is connected to the Einstein flash and the Einstein flash is connected to a power outlet, exposed metal components like the USB port or antenna spring on the PowerMC2 can become electrified, posing a potentially serious shock hazard. If the PowerMC2’s antenna cover is broken, removed, or in any way damaged, DISCONTINUE USE IMMEDIATELY and contact PocketWizard.
Customers in the United States may continue to safely use the Einstein flash and PowerMC2 with the power cord supplied by Paul C. Buff and a properly wired USA-style three-pronged power outlet (NEMA 5) or with the Vagabond battery pack. If a properly wired NEMA 5 power outlet is unavailable in your location, ALWAYS UNPLUG THE FLASH PRIOR TO HANDLING THE POWERMC2.
The issue has been corrected for all PowerMC2 units sold by PocketWizard’s authorized distributor in the USA after February 15, 2014. Customers owning affected units are advised to immediately contact PocketWizard Technical Support at +1 802-318-4456 or via our inquiry page to arrange for the return of affected units for free servicing to reduce the risk of electrical shock. We urge you to contact us regardless of the condition of your PowerMC2. We greatly apologize for this inconvenience.
Setting up your PowerMC2
1. Update the firmware in your PowerMC2 to the most current version. The PowerMC2 can receive ControlTL, Standard, and E Release Channels. See the Transmitter Compatibility section below to help determine which firmware version to use, based on your transmitting radio. You can also see the PocketWizard Firmware page for more information about the different firmware protocols available.
IMPORTANT NOTE: Do not connect the PowerMC2 to the PocketWizard Utility via USB while the PowerMC2 is also connected to the Einstein E640 flash. Damage to your PowerMC2, Einstein, or computer's USB port could result. Make sure to disconnect the PowerMC2 from any attached flash first.
2. Connect the PowerMC2 to your Einstein™ E640 Flash via the remote port, then power on the flash.
3. Select the Channel and Zone via the E640’s LCD. Please see the Channels and Zones section below for details.
4. Use the Einstein's function and adjust buttons to disable the Einstein's optical flash. This is the box directly above the Channel box. You should see 2 downward arrows.
4. Set up your transmitting radio and take pictures normally.
5. If your transmitting radio has power control, you can use the camera’s Flash Exposure Compensation (FEC) to adjust power levels globally to all remote flashes. You may also be able to use the transmitting radio and/or AC3/master controller to adjust power to your remote flash(es) by Zone. See the Power Control section for more information.
The Status LED blinks Green every few seconds to indicate normal operation. It will blink Red in sync with a trigger.
Momentarily pressing TEST on the transmitting radio and/or pressing down on the LED on the PowerMC2 will also trigger the flash.
HyperSync and SyncView
HyperSync with PocketWizard Transmitters
Most studio strobes can only sync up to your camera's sync speed - about 1/200 or 1/250 for most current DSLR cameras. Our patented HyperSync® technology allows photographers to achieve faster flash sync speeds. Unlike HSS that uses a pulsing flash with lower power, HyperSync uses your flash's full power burst. That extra speed and light can be used to freeze action or cut ambient light - both of which can produce results never possible before. All you need is a MiniTT1, FlexTT5, or FlexTT6 on your camera to gain the benefits of HyperSync. While performance varies by the camera and flash equipment being used, HyperSync will get the maximum possible out of any configuration.
Please see the HyperSync Setup for details about using HyperSync with ControlTL radios.
SyncView with the Raven by Fusion TLC
The Raven takes PocketWizard's HyperSync technology to a new level. With the push of a button, the SyncView screen displays a never-before-seen representation of flash intensity over the length of the shutter cycle. A built-in light meter captures the flash profile and reveals timing in relation to the opening and closing of the shutter curtains. To adjust flash timing, simply rotate the ring dial to optimize timing of your flash. This link illustrates how easy it is to push your shutter speeds to their limits.
Please see the Fusion TLC website for details about using SyncView.
The PowerMC2 gives you the ability to adjust power to your Einstein flash from your camera's position, instead of having to adjust power on the Einstein itself. If you are using multiple remote flashes, you can assign each remote flash to a Zone and adjust the power of individual Zones as well. You can have as many remotes assigned to each Zone as you would like.
NOTE: Specific Power Control functions are based on the features of your transmitting radio.
Manual Power Control
You can adjust manual power to the remote flashes globally by using the camera's Flash Exposure Compensation (FEC).
If you are using the Raven or have a master controller on your transmitting MiniTT1, FlexTT5, or FlexTT6, you can adjust manual power to each remote Zone independently. The Einstein does not have TTL.
- If you are using a Raven, simply activate the Zone and use the dial to adjust power in manual mode. With PowerMC2 firmware update 4.216 or higher, manual power control is available in Zones A, B, C, and D.
- If you are using a MiniTT1, FlexTT5, or FlexTT6, adjust the manual power settings of your remote Einstein flash directly from a AC3 ZoneController, master flash, or master controller (such as the Nikon SU-800 or Canon ST-E3-RT) mounted on your transmitting radio. Manual power control is available in Zones A, B, and C.
Now you can work with total control with your remote lights, without leaving your shooting position. Please see the chart below for corresponding power levels.
With PowerTracking, you can pick the perfect light level and lock it in, then when you change any of your settings on your camera, the system adjusts for those settings and will automatically adjust flash power to give you the same exposure. Change your camera's exposure compensation to adjust the flash output, or make adjustments in aperture or ISO and the system balances your flash for proper exposure.
With only a MiniTT1, FlexTT5, or FlexTT6 on your camera, your camera’s FEC (Flash Exposure Compensation) control will adjust your flash power output level for all your PowerMC2-connected flashes as shown in the table below.
