Option Switch Operation
JrX Transmitter
Radio Channel (switches 1-4)
- The radio channel on your JrX Transmitter is set by the positions of the first four
switches. It is not so much important that you know what combination of switches creates a given channel, just make
sure to match the on/off pattern of the first four switches on your JrX Transmitter and JrX Receivers. This will ensure
that all units are on the same channel. Note that there are 16 total radio channels.
Disable Group at Low Dial (switch 5)
– The Disable Group at Low Dial switch is used in conjunction with JrX
Receiver units connected using the EZset system. The default position, OFF or “0”, will cause any strobes to fire at their
lowest output power when the JrX Transmitter’s power dial is set to its lowest position. When the Disable Group at Low
Dial switch is turned ON, or “1”, any attached strobes will not fire when a JrX Transmitter power dial is set to its lowest
position. In this mode, as soon as the power dial on the JrX Transmitter is turned slightly above its lowest setting, the
strobe will begin to fire at its lowest setting. This mode is beneficial when you would like to quickly turn off lights on a
certain group by simply turning the adjustment dial to minimum power.
Disable Level Updates (switch 6)
– The Disable Level Updates switch is used in conjunction with JrX Receiver
units using the EZset system to remote control power levels of various lighting devices. The default value of OFF, or
“0”, has Level Updates enabled. While Level Updates are enabled, any changes made on the group control dials will
be immediately sent to any JrX Receiver units. When the Disable Level Updates switched is changed to the ON or
“1” position, Level Updates will no longer be sent. This mode may be beneficial when a photographer is shooting
with an assistant. The assistant may have level updates disabled yet still be able to fire at the levels that the
main photographer is controlling. Note that when this switch is turned from ON to OFF, the levels of the dials are
immediately read and sent to JrX Receiver units. It is thus possible to also use this as a “safety” switch to lock in set
lighting while still being able to send occasional updates if minor level corrections are desired.
JrX Receiver
Radio Channel (switches 1-4)
– Same setup procedure as the JrX Transmitter
Group Setting (switches 5-6)
– Groups can be set according to the positions of switches 5 and 6. See diagram to
determine appropriate group setting. Note that the “No Group” setting will simply take the Receiver out of all groups
to enable the strobe to be set manually, while still triggering.
