4 Signal Handling
This section describes the signal handling of the GE cameras in the following section:
• “Camera Inputs” on page 19
• “GPIO Control Block” on page 20
• “GPIO Look-Up Table” on page 20
• “GPIO Label Tables” 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,
refer to “Asynchronous Reset” on page 39
The TM-1405GE has three externally controllable standard signals:
• Trigger (VINIT or EXT_TRIG) (CC1 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)
4.2 Camera Outputs
When the Asynchronous Trigger is used, the strobe output indicates the exposure period.
• I4 for strobe output (must be configured as CAM_STROBE)
