SPECTRA. You will have the ability to turn each color ON or OFF and adjust the intensity of each individually. THIS
STEP IS REQUIRED TO RE-ESTABLISH THE COMMUNICATION LINK WHENEVER THE SPECTRA LIGHT
ENGINE IS POWER CYCLED OR WHENEVER THE GUI IS STARTED.
3.2 TTL Interface
The purpose of the TTL Interface is to provide the end-user with a more predictable means (in terms of timing) of
enabling/disabling each individual light source in the LE. This is accomplished via the parallel port on a PC. Merely
Connect the Lumencor supplied TTL cable between the PC and the TTL port on the rear of the SPECTRA. The
integration and set up of the 3
rd
party laboratory software is very application specific and beyond the scope of this
document. For programming information, visit the Lumencor website at
and download the SPECTRA TTL Interface Specification. Contact support if you need more
assistance.
3.3 Monitor Connector (Dosimeter)
This connector provides a means for monitoring the output of the internal Dosimeter that is measuring the relative
power output of the selected light source in the unit. The connector accepts a standard BNC connector. Lumencor
does not supply a cable.
