STC-A33A B. Pulse Width Trigger Mode In the “Pulse Width Trigger Mode” with positive polarity, the camera exposure starts at the rising edge of the trigger signal and stops at the falling edge of the trigger signal. Therefore, in the case that the exposure positive polarity is selected, the actual exposure occurs when the trigger signal is at its high state.

STC-A33A C. Edge Preset Trigger Mode In this “Edge Preset Trigger Mode” with positive polarity, the camera exposure starts at the rising edge of the trigger signal. In this mode, the exposure duration time is based on the preset exposure time (shutter speed) by the camera setting communication or the DIP Switch on the rear panel.

STC-A33A D. H Reset Mode Normally, the video noise appears when the start of the trigger signal is applied before finishing the video out of the previous frame. This noise is caused by the SUB pulse, which is activated to clear all residual charges on the CCD prior to a new exposure.
STC-A33A V. Communication Protocol Specifications This camera has a communication function that enables external devices, such as the PC, to control the camera functions and parameters. Use the “CLCtrl” communication software (version 9.0 or later) to communicate, or follow the communication protocol described below to communicate with the camera.
