Triggered Strobe Mode:
Triggered Strobe Mode is activated via the Ethernet or RS-232 interface. In this
mode, the light output pulses once for every triggered signal that is received on the
shutdown pin on the Multi-Port connector. The light output’s on-time and delay time
are adjustable via Ethernet or RS-232. In Triggered Strobe Mode, the intensity of
the light output pulse can be setup to achieve greater levels than the Normal Mode
intensity. The Triggered Strobe Mode capabilities are: Max 1 kHz pulse rate, max
pulse width 1ms, 10% duty cycle.

Power Input:
The power input accepts a 5.5 mm barrel power plug with 2.1mm pin diameter, center
positive. The voltage input range is from 12 to 28 volts, but the voltage must be more
than the LED’s forward voltage to ensure proper performance. To be safe, use 24V
input voltage regardless of LED color or specific wavelength.
Strobing of the LLS 3 can be done with a 24V input; however, overdriving the LED to
twice the Normal Mode power is not possible unless at least 26V is applied. With a 24V
input voltage, some overdrive power is possible, but not twice the input power. An easy
way to power the unit for Strobe Mode is to use both rails of a +/- 15V power supply for
a total of 30V.
Multi-Port:
The Multi-Port connector is used for multiple signal input/output. Main power input can
be supplied using this connector instead of the power input connector. Other signals
available include: Analog 0-5V remote input, shutdown/trigger signal, and a fault signal.
There is also a convenient 5V DC output available and chassis ground connection (to
properly ground the chassis to earth ground). See Section 12.0 for pin-out information.
