Limelight 2

Updates to the Limelight 2 Hardware:

• Smaller footprint (note that the mounting hole spacing has changed in both dimensions)
• Increased FOV
• From 54 x 41 degrees to 59.6 x 45.7 degrees
• Improved build quality
• Rigid lens mount
• Improved plastic finish
• Tighter margins around ports and LEDs
• Light-pipe-exposed status LEDs
• Easier access to main power port
• Easier access to IP reset button
• Easier access to microUSB port
• POE jumper removed
• POE is always enabled
• Serial port removed
• MicroUSB cable provides power while flashing. No need to apply 12V power while flashing.
• Some LL1 units contained loud fans, and others contained quiet fans. The new LL2 fan's loudness is in-between those of the two LL1 fans.
• Status LEDs
• Inner green LED blinks quickly if a target has been acquired, and blinks slowly if no targets are in view.
• Outer yellow LED blinks slowly if the unit is using an automatic IP configuration, and remains solid if the unit is using a static configuration.
