5.7 General Purpose I/O (GPIO)
5.7.1 Introduction
The camera has one GPIO line that is accessed via pins 2 and 4 in the 4-pin M5 connector on the
back of the camera. The GPIO line can be set to operate as an input to the camera or to operate
as a camera output. The GPIO line is designated as line 1.
The next sections describe the differences in the GPIO electrical functionality when the line is set
to operate as an input and when it is set to operate as an output.
For more information about setting the GPIO line operation, see Section 6.1 on page 49.
For more information about the 4-pin connector, see Section 5.2.1 on page 26.
5.7.2 Operation as an Input
This section describes the electrical operation of the GPIO line when the line has been set to
operate as an input.
5.7.2.1 Voltage Requirements
:
NOTICE
The camera’s GPIO line can be set to operate as an input or as an output. Applying incorrect
electrical signals to the camera’s GPIO line can severely damage the camera.
1. Before you connect any external circuitry to the GPIO line, we strongly recommend that you
set the GPIO line to operate as an input or as an output (according to your needs).
2. Once the line is properly set, make sure that you only apply electrical signals to the line that
are appropriate for the line’s current setting.
Different voltage levels apply, depending on whether the standard power and
I/O cable or a PLC power and I/O cable is used (see below).
