8.0. User Control and Operating Modes
There are four modes of user control of the light source: Local, Ethernet, RS-232, &
Analog and two modes of operation. The LLS 3 can switch between any of the 4 control
modes automatically. There is no need for a remote/local switch. Simply start using the
interface and the LLS 3 will track changes to that interface until another interface is
utilized. The front intensity knob and the analog input controls can also be locked out to
prevent users from making unauthorized light changes.
A command to the Ethernet or RS-232 interface switches to the corresponding
interface. To switch to Local Mode, adjust the front intensity control knob either fully
clockwise or fully counter-clockwise. To switch to Analog Lode, apply a large voltage
swing to the Multi-Port connector’s analog input pin (i.e., adjust from 0V to 5V or 5V to
0V). After the large voltage swing, adjust the control voltage to the desired level.
8.1 User Control Modes
Local Control Mode:
In Local Mode, the light source output is adjusted via the front intensity control knob
and the light source is turned on or placed in standby via the front push button.
Local Mode can be locked out via Ethernet or RS-232 commands.
Ethernet Control Mode:
In Ethernet Mode, the light source functionality is controlled via the Ethernet
connector. See the Ethernet programming section for instructions on how to use this
interface.
RS-232 Control Mode:
In RS-232 Mode, the light source functionality is controlled via the RS-232
connector. See the RS-232 programming section for instructions on how to use this
interface.
Analog Control Mode:
In Analog Mode, the light source output is controlled via the green Multi-Port
connector’s analog input pin. Analog Mode can be locked out via Ethernet or RS-
232 commands.
8.2 Operating Modes
There are two modes of operation: Normal Mode and Triggered Strobe Mode.
Normal Mode:
In Normal Mode, the output intensity is controlled from 0-100% using any of the four
user control modes. In Normal Mode, the light output can be turned on and off using
the shutdown pin on the Multi-Port connector. Polarity of the shutdown signal can
be changed using the rear polarity switch.
