Input Signal and Photocoupler
The input signal from the external control
connector turns the photocoupler inside the
Control Unit ON and OFF to set and
write data. The input signal is compatible
with both the sinking and sourcing devices.
For a sinking device, the photocoupler is
OFF when the input signal is high, and for
a source type, the photocoupler is ON
when the input signal is high.

Set the Manual/External Mode Selector to EXT to set
External Mode. The value set with external control
is displayed on the digital display.
* Although it is possible to set the external control setting even the
manual/external mode selector is set to manual mode, the setting will not be

There are 256 levels to the light intensity. Use pins 1
to 8 (B0 to B7) of the external control connector. Refer
to the following table for the settings.
Continue writing data. Input a signal to pin 13 (BRTWR)
that turns ON the photocoupler for at least 50 µs.
After that, turn the photocoupler OFF to complete writing.

Continuous Mode
Refer to the following table and set the lighting mode to Continuous Mode.
ON/OFF Mode
(If the external trigger is not used, the Light Units are ON continuously.)
Refer to the following table and set the lighting mode to ON/OFF Mode.
The Light Units are turned ON or OFF according to the external trigger signal input.
Strobe Mode
(If an external trigger is not used, the Light Units are OFF.)
The strobe time can be set to between 40 µs and 40 ms in Strobe Mode.
Refer to the following table for the settings.
The Light Units are turned ON for the set time after the external trigger signal is input.
