 SHUTTER: output signal of shutter control.
 EX1: (output) RPF6 control or N (North) control for autoguide.
 EX2: (output) RPF6 control or S (South) control for autoguide.
 EX3: (output) RPF6 control or E (East) control for autoguide.
 EX4: (output) RPF6 control or W (West) control for autoguide.
 EXI: (input) autoguide input.
 TRIG INPUT: trigger input.
When activating the TRIGGER mode, it is necessary to provide the signal to start acquiring
images. In fact, when executing the function: "DC_GetCCD", the camera, after the Clear
CCD operation, will wait for the hardware signal to start the acquisition, i.e. the TRIG INPUT
signal.
This signal is RISING EDGE SENSITIVE
Once the signal is provided, after just 1-2 ns, the shutter will be opened and image acquisition
will start (the acquisition time is prefixed by the user). Then, after the hysteresis time for the
shutter closure, image downloading will take place.
 PWR: Warning main power supply, 13.8V.
 GND: ground.
Note: all signals are TTL compatible.
