4 Signal Handling
GE cameras signal handling is described in the following sections:
•
“Camera Inputs” on page 20
• “GPIO Control Block” on page 21
•
“GPIO Label Table” on page 22
• “Pulse Generators” on page 24
Refer to the Cam2Net User’s Manual for additional details.
4.1 Camera Inputs
For information on the polarity and type of the signals required to support specific camera functions,
please refer to the TM-6740CL manual.
The TM6740GE has four externally controllable standard signals:
•
Trigger (VINIT or EXT_TRIG) (CC1 equivalent)
• Integration Control (INTEG/ROI) (CC2 equivalent)
•
VD in (EXT_VD) (CC3 equivalent)
• HD in (EXT_HD) (CC4 equivalent)
The labels for these signals in the GPIO Control Block programming language are:
•
I0, for VINIT (must be configured as EXT_TRIG)
• I1, for VD in (must be configured as EXT_VD)
•
I2, for HD in (must be configured as EXT_HD)
• I4, for Integration control (must be configured as INT)
For normal exposure operation, the INTEG signal must be high. In the GPIO lookup table language:
Q5=1. When it is low, the CCD readout is inhibited. To use the Integration Control, set Q5=I3 in the
GPIO lookup table.
