L-478DR: Updating the PocketWizard MiniTT1/FlexTT5 firmware and setting a transmitting radio to use with the meter

  • PocketWizard MiniTT1 and FlexTT5 radios must be upgraded to the latest firmware to work with the Sekonic L-478DR. Firmware upgrades are performed using the PocketWizard Utility (see download instructions below). Using the PocketWizard Utility, click on “Check for Updates” and follow the directions presented.

  • To ensure the L-478DR is exclusively controlling the power level of remote flashes, the on-camera MiniTT1 or FlexTT5 should be set to “No Change (Trigger Only)” mode. This will allow the meter to be the master power controller, and make sure the camera triggers the remote flashes but does not change their power levels.

Using the PocketWizard Utility, follow these steps:

  1. Click the “Advanced Mode” check box located on the bottom left to reveal all available options and tabs
  2. Select the FLASH tab
  3. In the SPEEDLIGHT section, click the drop down and select “No Change (Trigger Only)
  4. Click “Apply Changes” to set the radio.

L-478D/DR: Upgrading Meter Firmware

APPLE MAC OWNERS USING CURRENT DTS SYSTEM-- EXTREMELY IMPORTANT!
Read Me First

The L-478D/DR meters feature upgradeable firmware. This important advance makes them futurepoof and allows you obtain operational improvements or new features free of charge on the sekonic website.

  • Firmware upgrade is performed using the Sekonic Data Transfer Software (DTS) program available free of charge. Download the software here:
    http://www.sekonic.com/Support/Downloads/DTSSoftwareforMACandWindows.aspx
    NOTE: The CD included with the meter has an earlier version of the Data Transfer Software (3.04). Do not use this software. Please obtain the latest version (v3.05) from Sekonic.com.

Once downloaded,

  • Attach the meter to your computer using a standard, mini USB cable (not included with meter).
  • Press the L-478D/DR power button to see the USB indication on the meter screen.
  • Boot up the Data Transfer Software Program
  • Click the “Update Settings” tab and the “ Update Check” button when it appears.
  • If number in the “Current Version window is lower than the number in the “Latest Version” window, click on the “Update” button to upgrade the meter’s firmware to the latest version.

Updating will take approximately 8-10 minutes. Do not unplug the meter until indicated by the DTS software screen.

L-478D/DR: Battery operation

The L-478D/DR are packaged with High Power Manganese AAA-type batteries. These batteries provide power enough to familiarize yourself with the many features of the meter. Sekonic recommends using Alkaline or Lithium AAA-type batteries for normal operation as these provide extended life.

Find out how to use the X-Rite ColorChecker Passport with Sekonic Gray Balance Card and Sekonic’s Data Transfer Software exposure calibration system.

NOTE: If you intend to use only the incident light measuring mode when measuring light with your L-478-series meter, you can still use Sekonic’s DTS system to calibrate the meter to a camera’s middle gray tone for best exposures. Using the Incident-Only mode does not require purchase or use of the L-478 meter’s accessory 5-degree Viewfinder.
