5.14 GPIO
The GPIO screen enables you to configure General Purpose Interface Input/Output functions.
If a rear panel with GPIO screw terminal connections is fitted, the controls on this screen will
be active. The screw terminal connector provides two GPIOs that can be configured as either
an input or an output.
5.14.1 GPIO 1 and 2
•
Unused:
GPI is inactive.
•
Input:
Configures GPI as an input.
•
Output:
Configures GPI as an output.
5.14.2 GPI 1 and 2 (Input)
When the GPI is configured as an input, a low to high transition will trigger the GPI input
function. Each of the following options is initial-edge triggered. Once this has taken place, the
option remains selected until some other process is initiated.
•
Freeze Ch1:
The output picture will be frozen and the Freeze check box on the
Output screen selected.
•
Black Ch1:
The output picture will be black and the Test Patterns – Black radio button
on the Output screen selected.
•
Pattern Ch1:
The output picture will be a ramp and the Test Patterns – Ramp radio
button on the Output screen selected.
•
User Memory 1 to 16:
Any saved user memories will appear in the GPI Input list. The
default memory name is “User Memory
N
”, where
N
is the memory number from 1 to
16.
The name that appears here is the same as that on the Memories screen. Triggering
this input will perform a memory recall exactly as it would on the Memories screen.
