2.2 Camera Rear Panel
2.2.1 Digital Interface
The Digital Interface is available as a 68-pin, high density, dual row, D type connector or, as a
purchased option, a 26-pin, high-density Camera Link connector that connects the camera to a
frame grabber board and a serial communication interface for camera control. The frame grabber
board processes and displays video from the camera. A complete technical description of the
connectors and the signals that they carry is contained in Chapter 4 of this manual.
2.2.2 Trigger
The TRIGGER coaxial SMA type input connector on the rear panel of the camera accepts CMOS
TTL signals with a threshold of approximately 2.5 volts. The trigger pulse should have duration of
at least 100 nanoseconds and should be transmitted to the camera using a coaxial cable
terminated at the camera. The camera synchronizes to an external event using this input. The
operator can set the camera to respond to a positive or negative going trigger signal. See the
timing waveforms in Chapter 4 of this manual.
2.2.3 Strobe
The STROBE coaxial SMA type connector on the rear panel of the camera outputs a signal that
is TTL compatible and can drive a 50-ohm load. The strobe output pulse should be transmitted
through a coaxial cable with a terminating resistor at the receiving end. The leading edge of this
output signal can be used to fire a strobe light. The output signal polarity is user-definable. See
the timing waveforms in Chapter 4 of this manual.
2.2.4 DC Power Input
The DC power input is a two-pin connector. The power supply voltage must be 24 volts DC,
± 4 volts DC, measured at the camera’s power connector. The current draw is a maximum of
1.0 amp with a typical draw of 0.8 amps.
WARNING!
Reversing the polarity of the DC voltage input or applying voltage levels in excess of 30
volts may permanently damage the camera. Pin 1 must be positive with respect to the
other pin. Pin 1 is nearest the RED DOT on the connector ring. See Figure 2-4.
