Page 5: Specifications
The LDI-6 has six discrete wavelength channels (RGGBBV) while the LDI-7 has seven (RGGBBV + 555nm). The LDI-6 has one output aperture for all channels and the LDI-7 has two output apertures: one for RGGBBV channels and another for the 555nm channel. 89 North supplies an optional 400 m bifurcated fiber to combine the two LDI outputs into one fiber. -
Page 6: Safety
5 Safety The LDI incorporates Class 4 lasers which produce heat as well as visible and UV light. Proper care must be taken in setup and operation to prevent injury. The laser emission output apertures are SMA-905 fiber connections which are located on a connector panel in the ‘fiber access area’... - Page 7 Additionally, the LDI incorporates a safety interlock which prevents laser emission when the fiber access cover is removed. CAUTION – Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. If the equipment is used in a manner not specified within this manual the protection provided by the equipment may be impaired.
-
Page 8: System Overview
Laser emission is delivered from the LDI through optical fibers which are connected to SMA optical connectors on the top of the LDI in the fiber access area. For the LDI-6 and -7, one SMA output (right side of unit when viewed from the front) corresponds to a multi-color laser diode module which contains the six laser lines 405nm, 445nm, 470nm, 520nm, 528nm, 640nm. - Page 9 LDI Overview Figures LDI: Figure 2: LDI Model 15000-MNL-01 Rev A...

Page 14: Breakout Box (Optional)
8 Breakout Box (Optional) The optional ‘Breakout Box’ provides an external analog intensity control and TTL shutter control connections for each of the channels in the LDI and routes them to the appropriate pins of the LDI interface connector. The Breakout Box connects to the LDI unit with the supplied DB25 male to male cable. BNC connections are provided to connect to the customer supplied equipment (BNC cables not included). -

10 Operation Caution - use of controls or adjustments or performance of procedures other WARNING: than those specified herein may result in hazardous radiation exposure. Even with protective eyewear, never look directly into the fiber or allow for skin to WARNING: be exposed to the beam, as invisible laser radiation can be harmful to the eyes and skin. - Page 21 Depress the power switch on the front panel to turn the LDI on. The unit will start in Warm-Up mode, as indicated by the yellow indication on the front panel status ring LED. The LDI is ready for operation when Warm-Up is completed, which is indicated by the front panel status LED turning green.
- Page 22 Status Indicator Status Bar Figure 16. Here, the ring in the upper right corner of the GUI is yellow, indicating that the LDI is in Warm-up mode. The operating mode is indicated in the status bar in the lower left corner. Setting the Control Mode After the unit completes Warm-up, configure the desired shutter and intensity control modes from 'Control Modes' tab in the 'System Info &...
- Page 23 Figure 17. System Info & Settings can be accessed by pressing the gear icon. Also note that the ring indicator is now green, indicating that the LDI is no longer in Warm-up mode. The ‘Control Mode’ tab lists options for the control modes of laser intensity and shutter control (Figure 18).

- Page 25 If 'Host USB' mode is selected for intensity control, set channel intensities to the desired levels (0-100%) via the slider, arrows (incrementing by 1%), or text controls in the GUI (Figure 20). Additionally, clicking in the intensity bar space for a given channel will increment the intensity setting by 10%. If 'External Analog' control mode is selected for intensity control, verify the applied voltage levels (0-5V) correspond to the desired intensity settings as reported in the GUI.
- Page 26 Attempting to operate more than 4 channels simultaneously could lead to performance degradation and/or over-temperature conditions. Operation of more than 4 laser lines simultaneously is not a supported operating mode. Light will not emit from the system until Run mode is selected. If 'External Digital' mode is selected for shutter control, verify that the shutters indicated as Open correspond to the desired channels.
- Page 27 Indicates the system is has a fault Other indications are utilized for factory service modes. If the Status Indicator LED displays a color or blink rate other than described above, contact 89 North. See “Troubleshooting”. Laser Ready Indicators As shown in Figure 4, the front panel of the LDI includes two Laser Ready Indicators. These indicators illuminate blue when laser emission through the corresponding aperture can occur.
