This section describes the signal handling of the GE cameras in the following section:
• “Camera Inputs” on page 18
• “GPIO Control Block” on page 19

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 42
The TM-1327GE 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)
