Electrical Interfaces & Connectors

NOTE: Axsun SS-OCT Laser Engines and Integrated Engines typically include a spare mating connector for the Auxiliary & Interlocks receptacle which is jumpered appropriately to enable laser emission (i.e. the Swept Laser Interlock not tripped). The user is expected to replace this mating connector once their external interlock control circuitry is implemented.

Benchtop

The Benchtop Enclosure configuration is provided with an external AC/DC converter which supplies ~12 VDC from 100-240 VAC mains. This external power supply's cable is plugged into the "12 VDC" socket on the rear panel of the enclosure.

Standard OEM

The OEM engine is provided with a 100-240 VAC external auto-switching power supply which supplies 12 V/3.3 A. The external power supply is plugged into the power socket of an adapter cable provided with the OEM engine.

Small Form Factor

The SFF engine is provided with a 100-240 VAC external auto-switching power supply which supplies 12 V/3.3 A. The external power supply is plugged into the power socket of an adapter cable provided with the SFF engine.

OEM w/ EDAQ

The OEM engine with EDAQ is provided with a 100-240 VAC external auto-switching power supply which supplies 12 V/3.3 A. The external power supply is plugged into the power socket of an adapter cable provided with the OEM engine.

OEM w/ Camera Link DAQ

The OEM engine with CLDAQ is provided with a 100-240 VAC external auto-switching power supply which supplies 12 V/3.3 A. The external power supply is plugged into the power socket of an adapter cable provided with the OEM engine.

PCIeDAQ

For safety reasons, there is a hardware-mediated interlock with NO firmware interaction.

Once Interlock Pin 2 is tripped (disconnected from 3.3V), the laser emission will stop in less than 2 us.

As an additional failsafe for instances where there could be noise on Pin 2, the driver board has been designed to NOT automatically re-enable laser emission when this Pin 2 gets reconnected back to 3.3V. Rather, both of the following needs to be done:

1) reconnect interlock Pin 2 to 3.3V

AND

2) issue the Laser Emission ON command (AFTER Pin 2 is at 3.3 V), which can be achieved either:

  • via SW interface over USB (StartScan() in API or Run button in OCTHost)

OR

  • via toggling the digital input on Pin 1
