Break Out Boxes are Ready
• Breakout boxes facilitate interface verification without significant risk to flight hardware. Note that
the LAT electronics design does not easily permit measurements of LVDS signaling characteristics
at data rate. Four boxes are required:
– 26 pin interface
– 44 pin interface
– 78 pin interface
– 104 pin interface
• Adapter cables adapt between different pin outs, connector styles and sizes. Examples of
breakout boxes are shown in the following picture:

EGSE TEST REQUIREMENTS: MD-00408
• Configuration of EGSE shall be controlled via released
documentation
• EGSE shall be acceptance tested
• EGSE shall be validated before use if it has been moved,
reconfigured, or repaired
– Validation shows that equipment is both ready for use and safe to
use
• High degree of confidence that equipment in that configuration
has full operating capabilities
– NASA guidance
• Perform an EICIT and an SVT to ensure electrical safety
• Trip points on circuit breakers, current limits in power supplies,
shall be verified
• While everything is validated, the scope of validation is tailored
for each piece equipment type

– Calibrated Instrument
– Validation Tests
• Embedded within test procedure that calls them
– STATUS: Meter purchased exceed maximum voltage for parts in
some equipment, so we are re-procuring
• Borrowing “Safe” DMM’s in the meantime
• Hand Tools
– Procured, cleaned, and placed in toolbox within cleanroom
• Automated Test Equipment for Safe to Mate
– All parts received - calibrated
