2.1.3 Connector Types

The 6-pin connector on the camera is a standard IEEE-1394 socket.
The 9-pin Micro-D plug is Molex Part Number 83611-9006 or the equivalent.

2.2 Video Data and Control Signals

2.2.1 Input Signals

2.2.1.1 ExTrig: Controls Exposure Start

An external trigger (ExTrig) signal can be used to control the start of exposure. ExTrig can be a
periodic or a non-periodic function. When the camera is operating under the control of an ExTrig
signal, the frequency of the ExTrig signal determines the camera's frame rate. For more detailed
information on using the ExTrig signal, see Sections 3.2 and 3.3.
As shown in Figure 2-3, the input for the ExSync signal is opto-isolated. The voltage of the LED
in the opto-coupler is 1.4 V. The absolute maximum input current for the LED is 50 mA.
For the ExSync input, a current of more than 5 mA means a logical one. A current of less than 0.1
mA means a logical zero.

2.2.2 Output Signals

2.2.2.1 IntEn: Indicates that Exposure is Taking Place

The integration enabled (IntEn) signal indicates that exposure is taking place. The IntEn signal will
be high during exposure and low when exposure is not taking place.
As shown in Figure 2-3. the output for the IntEn signal is opto-isolated. The maximum forward
voltage is 35 V, the maximum reverse voltage is 6 V, and the maximum collector current is 100
1
mA.
A conducting transistor means a logical one and a non-conducting transistor means a logical zero.

2.2.2.2 TrigRdy: Indicates that Exposure Can Begin

When the trigger ready (TrigRdy) signal goes high, it indicates that exposure of the next frame can
be triggered. Section 3.3 explains the operation of the trigger ready signal in more detail.
As shown in Figure 2-3. the output for the TrigRdy signal is opto-isolated. The maximum forward
voltage is 35 V, the maximum reverse voltage is 6 V, and the maximum collector current is 100
1
mA.
A conducting transistor means a logical one and a non-conducting transistor means a logical zero.

The opto-isolator used in the camera is a Sharp PC3Q64Q or the equivalent. A detailed spec
sheet for this device is available at the Sharp Microelectronics Group (www.sharpmeg.com).
