Is the FJ Wireless Radio Trigger compatible with the Canon RT system? Can I control Canon Speedlites with the FJ-X2m, FJ-X3m or FJ80II Trigger?



Canon users have the 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 on a regular basis, 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 particularly in high wireless trafficked environments as well as adding the additional functionality available with the FJ system.  


Before beginning the process, you may find it beneficial to reset the FJ triggering device to factory defaults. Check the article-How to do a Factory Reset of my FJ gear for details.  

Connecting Your FJ gear for RT operation

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 are from 0000-1000 so the two digit equivalent will be 0000-0099 on your Canon gear to match the FJ system. Your FJ manuals and accompanying videos should have specifics on how to do this. 

FJ200- will need to have the Wireless setting in the settings menu set to RT/ID. 

FJ80 or FJ80II - will have the RT/ID set to ON along with the matching RT/ID # in the settings menu.   FJ400 -continues to use the TTL/ALL setting in menu 1 along with the RT/ID assigned through a long press of the RT/ID button in menu 2.  

FJ triggers- will need to have the matching 2 digit RT-ID set 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

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.


Choose a group assignment using the “Gr” button. Canon RT will allow groups to be set between A and E. Typically you will want your speedlite set to a different group than your FJ400. Make sure the group chosen is activated on the trigger (not displaying SLP). 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.  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 assure the system is linked. 

Limits of the RT System Which Affect the FJ Trigger

When using the Canon RT setup with the FJ400(s) and multiple RT speedlites, the FJ triggers, the test button may not fire all the 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 which corresponds 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 in order to disable the ID function and assure connectivity.  Canon RT/FJ  users must limit their channel choices to 1-15 in order 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
