WARNING: All electrical signal connections and disconnections must be made with the device in a powered-off state.
All Axsun laser engines expose interlock inputs for the swept laser emission and aiming laser emission, as shown in the detailed diagrams below for each engine configuration.
If the Swept Laser Interlock is tripped (i.e. pulled to GND or allowed to float by an external circuit), the swept laser emission will be disabled within 2 microseconds.
A tripped Swept Laser Interlock will latch the swept laser emission into a disabled state, and two distinct steps are then required to re-enable swept laser emission:
Reconnect the Swept Laser Interlock input to ~3.3V, then
Explicitly re-issue the "Swept Laser Emission -> ON" command, either via software interface (API or GUI tool) or by toggling the Swept Laser Emission On/Off Control input.
A tripped Aiming Laser Interlock does not latch the aiming laser into the disabled state and thus the aiming laser emission can be reenabled by reconnecting the Aiming Laser Interlock input to ~3.3V (no additional emission-on command is needed).
NOTE: Disabling swept laser emission or aiming laser emission in response to a tripped interlock input is accomplished in hardware logic only; there is no software or firmware interaction involved in this behavior.
NOTE: Axsun laser engines typically ship with a temporary mating connector for the Auxiliary & Interlocks receptacle whose pins are jumpered appropriately to allow laser emission (i.e. the interlocks are not tripped when this connector is installed). The user is expected to replace this temporary mating connector once external watchdog circuitry is implemented in order to control the laser emission interlock behavior.
The Azmyth 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 Azmyth engine. Outputs for the Sweep Trigger and K-clock (if installed) are available on both SMA (single-ended signaling) and SATA (differential signaling) connector types.
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.
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.
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.
The OEM engine with Ethernet DAQ 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.
The OEM engine with Camera Link DAQ 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.
