Einstein™ Firmware Update

Current Version Date Size
Version 60 June 30, 2023 1.0 mb

The 'Version 60' firmware updates from 'Version 58' firmware:

  • While using a Raven and CSXCV, the Raven will no longer turn off the user’s E640 slave eye setting. Rather, the E640 will keep whatever the user put in manually.

  • Fixed bug where the historical number of flashes would be reset after updating from lower than firmware version 58.
  • Fixed bug where Model Mode would default to OFF when AC power is cycled (present only on v58).


Do I need an update? How do I know which version I have?
When your Einstein™ unit is first powered on, the firmware version will flash on the bottom of the screen for approximately 2 seconds. The firmware version can also be found on the diagnostics screen in the lower left corner. If you can’t find it, call us and we’ll help determine your version.

Please read all instructions before beginning this firmware update. Even if you have updated the firmware on your Einstein™ unit before, please review the instructions for this update as some steps have changed and there are special requirements that are specific to this update.



MicroSD memory card
MicroSD card (16GB or less in capacity)
New card or an empty card that has been formatted (FAT, FAT16 or FAT32)

MicroSD card reader connected to your computer
Card reader capable of accepting MicroSD cards


STEP ONE Download the Firmware


  • Downgrading to a previous version of firmware is NOT possible after the version 58 update is performed.
  • Do NOT attempt to load the firmware more than once. If you already have version 58 firmware or if you are uncertain as to whether or not the update was successful, do not attempt to update the firmware again - contact customer service.
  1. Click here to download the latest firmware update.
  2. Save the file “E640_V60.zip” to your hard drive, we recommend to the desktop.

***PowerMC2 users STOP*** E640 Firmware 55 or higher can only be used with the Raven. Please contact Pocket Wizard prior to updating for more details if you are using a PocketWizard transmitter.

STEP TWO Copy the firmware to your MicroSD card

MicroSD Card Reader

  1. Insert the MicroSD card into the card reader that is connected to your computer.
  2. Navigate to the MicroSD card drive, click to open and confirm your MicroSD is empty. Leave this window open.
  3. Navigate to the “E640_V58.zip” file that you saved to your hard drive (desktop) and click to open, unzipping if necessary.



Drag to MicroSD card

  1. In the window for the downloaded file, you will see a folder titled “PCBUFF” - click and drag this “PCBUFF” folder to the MicroSD card by dragging the file name/icon into the MicroSD card window.
    • Note: Make sure the folder moved to the MicroSD card is named "PCBUFF".
  2. Eject or safely remove the MicroSD card from the card reader.



STEP THREE Update the firmware on the Einstein™ unit using the MicroSD card

MicroSD to Cyber E640

  1. Disconnect the power cord from the Einstein flash™ unit.
  2. Take your MicroSD card with the downloaded firmware and insert it into the Einstein™ unit. The MicroSD slot is located on the top, rear side of the unit. Insert the MicroSD card into the slot, metal contacts first, facing the rear panel. The card must be inserted at a 90º angle. Push until the card clicks into place.
  3. Connect the Einstein™ unit’s power cord into a suitable power source, then connect the cord to the power jack on the back panel of the unit.
    • Note: It is very important that you use a reliable power source when you perform this update. Portable power system use is NOT recommended. If the unit loses power during the update process, the process may fail and cause major problems with the unit, requiring you to send the unit in for service.
  4. Your firmware update should now start. The LCD screen on the back panel of the Einstein™ unit will go solid white and begin to flicker quickly, alternating between a fast and slow pace. The procedure should take approximately 25 seconds.
  5. Once the flickering has stopped, remove the MicroSD card by pressing in and letting it pop up.

Power ON the flash unit. As the unit reboots, “SW-0173 Ver 55” should appear on the screen.

STEP FOUR Updating Additional Einstein™ Flash Units (if necessary)

  1. Place the MicroSD card back into the card reader that is connected to your computer.
  2. Navigate to the MicroSD card drive folder, and click to open.
  3. Click and drag the “PCBUFF” folder (the same downloaded folder that you clicked and dragged before) to the MicroSD card. When you drag the folder to the MicroSD card, you may be prompted with a message stating that there is already an item named “PCBUFF” in this location. Click “Replace” or accept the request to replace this file. DO NOT MERGE OR COMBINE FILES
  4. Eject or safely remove the MicroSD card from the card reader.
  5. Repeat STEP THREE (above) to update the next Einstein™ flash unit in your setup.

    Note: You will need to reinsert the MicroSD card into your card reader and drag the “PCBUFF” folder onto the card each time before updating each individual unit. You can NOT move from one unit to the next without going back to the computer first as the necessary files do not stay in place on the card after the update.


Einstein™ Firmware History

The firmware 'Version 60' update includes ALL PREVIOUS UPDATES that have been released, updating Einstein™ units from versions 19, 20, 22, 26, 29, 30, 31, 50, 52, 53, 55, and 57.

Version 58:

  • Improve Compatibility with FusionTLC’s Raven. The flash unit’s configuration is no longer overwritten by the Raven – flash mode and model mode now remain the same when powering on via the Raven.

  • Bug fixed where if a remote requests lower than -8.0f flash power, the Einstein would revert to full power.

Version 57:

  • The previous power state is now saved when the unit is unplugged. For example, if the unit is on when the power is unplugged, and then the unit is plugged back in, the unit will automatically boot. If the unit is off when power is unplugged, the unit will stay off when plugged back in.

Version 55:

  • Pocketwizard E-Release channel support – channels now range from 1-32 and zones from A-H.

Version 53:

  • Improves communication between the processor and LCD screen. This can often correct an issue where a customer’s flash unit displays a white screen.

Version 50:

  • Runs the fan at a faster speed for a few seconds at startup. This can correct an issue where the fan fails to start when powered up, which could lead to the unit shutting down due to heat.

Version 31:

  • Allows the flash unit to accept microSD cards formatted to FAT32 (up to 16GB) to be used.

Version 30:

  • Corrects the displayed flash duration values for the settings from -2f to -2.9f while in action mode. (Note: Values are communicated to the Cyber Commander™ unit from the Einstein™ E640 flash unit, therefore no update is necessary for the Cyber Commander™ unit.)

Version 29:

  • Allows the fan to be controlled by the internal temperatures of the light. The fan will run at slower speeds at cooler temperatures and higher speeds as the light warms up.

Version 26:

  • Updates internal component drivers to latest versions. Users will not notice any changes in performance or features from firmware version 26.

Version 22:

  • Updates for compatibility with the PocketWizard® PowerMC2 remote.
  • With the Cyber Commander™ remote, when the Einstein™ unit is not in a selected group, the new firmware turns off its modeling lamp and disables the sync jack and slave eye.

Version 20:

  • Increases the pump temperature reading at which the light shuts off (from 60°C to 105°C), increasing the time before thermal shutdown.
  • Includes a cosmetic change to the diagnostics screen.

Version 19:

  • Corrects an issue where the light may double fire when a triggering cord is connected in the 1/8” sync jack.

NOTE: Downgrading to a previous version of firmware is NOT possible after the version 50 update is performed. The version 50 update includes all updates listed above, and returning to a previous version after the update is performed will NOT be possible.
