Check the waveform output from the TrigPort.
The introduction of different GPIO PORT MODE
MODE0: Generic GPIO output mode / Auto Guide Port
In this mode. Four GPIO port is all output . You can control each port to output high or output low with the API. This mode
does not controlled by Enable TrigOut.
You can select the check box of MODE0, GPIO1,GPIO2,GPIO3,GPIO4 to test this mode. This mode is also been used to test if
the socket io port working well.
MODE1: 6PIN QHY-GPSBOX mode
In this mode, Four GPIO port is configed as gps_clock, gps_data, shuttermeassure,gps_control. You can connect with
QHYCCD-GPSBOX. The camera will output the shuttermeassure signal to GPSBOX and GPSBOX will send the data to camera.
Camera will replace the first some pixel to the gps data .
MODE2: 5PIN Generic TrigOut / TrigIn mode
In this mode, Four GPIO port is configed as TrigOut, ShutterMeassure, TrigIn, LinePeriod . Only TrigIn pin is input direction
and other three pin is output direction.
In some camera, like QHY4040,QHY2020,QHY42PRO,QHY6060, The shuttermeassure waveform rising edge is the start
exposure time and falling edge is the end exposure time in other camera like QHY600,QHY268, QHY411,QHY461 etc, The
shuttermeassure waveform is the vsync signal . It is near to the end of exposure time of the first row. For more information of
TrigOut,LinePeriod. Please see some other document of QHYCCD supplied.
