● Anti-chattering process for Trigger input
In the characteristic of the open collector circuit, the signal is skewed. As a result, an unstable logic value
occurs. To filter out an unstable logic value, this camera has the anti-chattering circuit. Therefore, Random
Trigger Shutter operates only in the stable logic value.
