With the Sekonic RT-32CTL module in your meter, you can trigger PocketWizard ControlTL radios, including the FlexTT5, FlexTT6, PowerM2, and PowerST4, using Legacy ControlTL Channels. The module can also trigger Legacy Standard Channels, for all PocketWizard radios using Legacy firmware. This lets you meter your remote flashes completely wirelessly. The module cannot trigger using E Release Channels at this point.

Channels

When using the RT-32CTL module in your compatible Sekonic light meter, It will simultaneously send trigger signals out on both your selected Standard Channel and selected ControlTL Channel when pressing the meter’s triggering button.

Standard Channels are used with Plus series and MultiMAX radios, as well as many flash packs with built-in PocketWizard radios. ControlTL Channels are used with the MiniTT1, FlexTT5 with Speedlites, FlexTT5 with the AC9 AlienBees Adapter, PowerST4, and PowerMC2.

Newer L-758 DigitalMaster light meters can select Standard and ControlTL Channels and zones independently.

The L-358, and previous versions of the L-758 meter, use a channel mapping mode (see table below) to pair up Standard and ControlTL channels automatically.
