OPTICAL HEAD:
Connects to the optical head of the filter. This should be connected before the controller is turned on. If
the cable is not connected while the power is on, then the controller must be restarted. The controller
screen will remind the user to power down and connect the optical head:
“Power Down To”
“Connect LC Head”
CAUTION
Always connect the optical head to the main controller unit before powering on.
The maximum current output from the optical head connector is 1 A, and the optical head does not
support hot plugging. Plugging or unplugging the connector while the unit is powered on can cause
damage to the optical head and/or controller.
USB:
Connects to the computer for software or command-line control.
TRIGGER OUT:
A BNC connector output trigger issued by the controller during every tuning cycle. For normal trigger
mode, the TRIGGER OUT raises to 5 V at the beginning of a wavelength tuning cycle. It remains high
during the tuning time, and drops to 0 V once the filter settles into its new wavelength. The user also can
use the command-line or software to flip the trigger out waveform. Please refer to the schematic below
of the trigger out signal while choosing Normal or Flipped mode.
NOTE:
Since the tuning time varies with wavelength (and depends on the to and from wavelength), the
duration of the TRIGGER OUT also varies accordingly.
