Using FJ Triggers with Canon RT Speedlites: Setup and TipsUpdated a month ago

Canon users have two camera choice options with the FJ gear. The "Canon RT" choice on the FJ system is designed to work alongside Canon cameras with Canon RT speedlites, including the RT-compatible Canon EL-1. 
You can also use the FJ system triggers and speed lights as a triggering, mode selection (TTL or Manual), and remote power adjustment control for Canon RT-compatible speedlites with a Canon camera, independent of the FJ flash units.

Please note that the Canon RT system, whether using a Canon RT trigger or the FJ system with “Canon RT” selected, has a minimum power adjustment of 1/128, which corresponds to power level 2 on the FJ400 Strobe. Standard in-camera menu settings apply.

The RT system will only support channels 1-15. When switching between RT and Canon camera choices regularly, use a channel between 1-15 so both choices are supported. When using a Canon camera without Canon-branded RT speedlites, FJ users should choose the CANON camera choice, which has been shown to be more reliable in high wireless trafficked environments and offers additional functionality with the FJ system.

Resetting FJ Gear

Before beginning the process, you may find it beneficial to reset the FJ triggering device to factory defaults. Check the article on how to perform a factory reset of your FJ gear for details.

Connecting Your FJ Gear for RT Operation

1. Set your FJ strobes and speed light clients to the same channel (CH) and the same RT ID# as selected on the triggering device.
   • Canon RT ID#s range from 0000-1000, so the two-digit equivalent will be 0000-0099 on your Canon gear to match the FJ system.
   • FJ200: Set the Wireless setting in the settings menu to RT/ID.
   • FJ80 or FJ80II: Set the RT/ID to ON and match the RT/ID # in the settings menu.
   • FJ400: Use the TTL/ALL setting in Menu 1 and assign the RT/ID through a long press of the RT/ID button in Menu 2.
   • FJ Triggers: Set the matching two-digit RT-ID from the trigger's settings menu.

Once the channel and RT ID# on the trigger and strobe are matching, your triggers and strobes should indicate a connection by highlighting “Canon-RT” green on the trigger and “ID/RT” green on the strobe. If the green indication does not occur after about 3 seconds, press the ID/RT button on the strobe to reboot the connection.

Connecting Your 600RT Speedlites to the FJ Trigger

1. Turn on your RT Speedlite and press the double arrow link button until “ETTL” or "M" appears in the upper left corner, “slave” appears in the center of the screen, and the wireless symbol (not the lightning bolt) is in the upper right corner.
2. Choose a group assignment using the “Gr” button. Canon RT allows groups to be set between A and E. Typically, set your speedlite to a different group than your FJ400. Ensure the chosen group is activated on the trigger (not displaying SLP).
3. Press the “MENU 1” button on the speedlite twice to enter “MENU 3”. Once in Menu 3, press the “CH" button and set the channel to the same one as the strobe and trigger. Press the “ID” button and set the RT/ID to the same one as set on the strobe and trigger. Enter a four-digit RT ID with the first two digits set to "00" followed by the two digits set on your FJ units.
4. Confirm the Link. The link LED on your speedlite should now be green to confirm the link. If the link is not occurring, try cycling the link button to establish the link. Fire a test exposure via the camera shutter to ensure the system is linked.

Limits of the RT System Affecting the FJ Trigger

When using the Canon RT setup with the FJ400(s) and multiple RT speedlites, the FJ triggers’ test button may not fire all connected flashes. Test firings with the "Canon RT" camera selection should be done via the camera's shutter release. Canon's "RT" system is not compatible with multi-brand cameras and should not be combined with other brands of cameras when triggering an FJ400.

The Canon RT system, whether using a Canon RT trigger or an FJ system triggering device with “Canon RT” selected, has a minimum power adjustment of 1/128, corresponding to power level 2 on the FJ system strobes. Remote toggling of the FJ modeling lights and audible beep are also disabled when using the RT setting.

When using the FJ system independent of any RT speedlites, using the "Canon" camera choice on the trigger is recommended. Exiting the Canon RT camera selection to change to "Canon" or other brand choices may require you to reboot (turn off and restart) the FJ strobes to disable the ID function and ensure connectivity. Canon RT/FJ users must limit their channel choices to 1-15 to match the limitations of the Canon RT system.

In some environments, wireless connectivity issues may be related to the RT system itself, as seen in Canon forum postings like this one: Solved: Re: Canon 600EX II-RT drops link- HELP! - Page 8 - Canon Community.
