Main Functions
GPIO ( Digital Input/Output Settings)
The unit can input/output the following signals to and from external input/output connectors.
External output
TTL Out (Line1)
External input
TTL IN (Line4)
CC1 (Line7)
These signals can be used as triggers and other necessary signals within the camera or as signals
output from the camera to the system, such as those used for lighting equipment control.
In addition, a pulse generator for generating custom pulses and a NAND module for performing logic
operations are built into the camera. The two can be used together for a variety of purposes, such as
noise removal for trigger signals and phase adjustment for pulse outputs.
Such functions are generally referred to as GPIO functions.
Signals are selected as follows.
• When using external signals or the signals of each GPIO module as trigger signals:
Select in [Trigger Selector] > [Trigger Source].
• When selecting the signals to use for external outputs:
Select in [Line Selector] > [Line Source].
• When selecting the input signal for the NAND logic line:
Select in [Line Selector] > [Line Source].
• When selecting the clear signal for [Pulse Generator]:
Select in [Pulse Generator Selector] > [Pulse Generator Clear source].
