Status LEDs
The two LEDs on the side of the cameras can be programmed to show status of a variety of the camera functions, such
as the camera has reached the set temperature, the shutter is open, or the camera is waiting for an external trigger.
Alternatively, the LEDs can be turned off if you are concerned about stray light.
Camera I/O Port
Apogee camera systems provide an 8 pin Mini DIN connector, enabling various hardware signals to be controlled by the
device. Five of the eight pins are programmable, and of the remaining pins, pin 6 is for EEPROM Write Protect, pin 8 is
ground and pin 7 is a +12 volt line. Each of the five pins may be programmed to be either a specific fixed- function I/O
pin, or else a general purpose and user-defined I/O pin.
I/O Pin-out
The programmable pins of the Apogee I/O port are 3.3V, LVTTL signals.
The pin out is shown in the following illustration. The numbers correspond to the I/O pin numbers, defined in the table
below:
