The “Canon RT” choice on the FJ2-Xm is designed to work with Canon cameras with Canon RT speedlites alongside the FJ400. While many cameras require the in-camera menu wireless to be set to “off” or “disable”, Canon cameras may require wireless to be set to “enable” for proper TTL operation. You can also use the FJ-X2m as a triggering, mode selection (TTL or Manual), and remote power adjustment control for Canon RT speedlites and a Canon camera independent of the FJ400. Please note that the Canon RT system, whether using a Canon RT trigger or the FJ-X2m 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.
Connecting Your Canon RT System to the FJ400 Strobe
First, make sure your trigger’s camera choice is set to Canon RT. Then, in the trigger’s opening menu, select your channel (0-15) by pressing on the middle button for "CH" and scrolling to your channel choice. If a music note (♫) icon appears above the middle button instead of “CH”, press the menu button to change the screen to the opening menu. Once the channel is set on your FJ-X2m trigger, press the middle and right buttons simultaneously (below the "C.Fn") to enter the setup menu. Scroll to “RT ID#” and press the scroll wheel to activate the ID#. Then, scroll to select your ID#. Hit the "OK" button to return to the main menus.
Connecting Your Canon 600 RT and FJ400 to the FJ-X2m Trigger
First, set your 600 RT and FJ400 to the same channel and ID# selected on the FJ-X2m trigger. To do this on the FJ400, press the “MENU 1” button to enter the “MENU 2” screen. Then, press the “CH” button to highlight your channel ID. Use the wheel to scroll to set the appropriate channel number. Now, press the “ID/RT” button to highlight your ID#. Use the wheel to scroll to select the appropriate ID#. If pressing the “ID/RT” button does not highlight the ID# icon on the screen and prevents you from setting your ID#, return to “MENU 1” and ensure that the Wireless button reads “TLL/ALL”. If it reads “OFF”, press the button to enable the wireless function.
Once the channel and ID# on all units are matching, your FJ-X2m and FJ400 will 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 to reboot the connection.
Your 600 RT mode should be set to radio slave and should also automatically link providing the channel and ID numbers are consistent with the FJ-X2m and FJ400.
Limits of the RT system which affect the FJ-X2m trigger
The Canon RT system, whether using a Canon RT trigger or the FJ-X2m with “Canon RT” selected, has a minimum power adjustment of 1/128 which corresponds to power level 2 on the FJ400 Strobe. Remote toggling of the FJ400 modeling light and audible beep are also disabled when using the RT setting. When using the FJ400 and FJ-X2m trigger independent of any RT speedlites, using the "Canon" camera choice on the trigger is recommended.
