MODE3: 4PIN GPS Card TrigIn mode
In this mode. there is two pin is configured as ouptut . Both of the two pins is the shuttermeassure signal but one of it is
inverted. This is suitbale for some GPS card which need such a “differencial signal”. But please note this is not LVDS signal. It
is still TTL signa,

MODE5: Multi-Camera Slave Mode

MODE6: LED Calibration Mode
By using the controlled LED pulse, we can calibrate the distance from the TrigOut or ShutterMeassure signal to the real
pixel/row start/end exposure time. To use this mode. You need to connect a LED to one GPIO pin and let the camera capture
the flash that output from the camera. The start time and end time relative with the TrigOut/ShutterMeassure can be set by
APIs. By check if the camera captured this pulse. You will get the delta time of the TrigOut/ShutterMeassure signal and use it
to calibrate the messured GPS time.

UVLO Function Introduction
Note: Now only QHY600, QHY268, QHY410, QHY411, QHY461, QHY533 cameras have UVLO function.
What is UVLO?
UVLO Under Voltage Locking), is primarily intended to protect the electronic device from damage caused by abnormally low
voltages.
Our daily life experience tells us that the actual operational voltage of an electrical device must not significantly exceed the
rated voltage, otherwise it will be damaged. For such precision equipment as cameras, long-term work at too low input
voltage can also be detrimental to the working life of the camera, and may even make some devices, such as power manager,
burn up due to long-term overload. In the all-in-one driver and SDK after 2021.10.23 stable version, the camera will give a
warning when the input voltage of the camera is below 11V.
