Trigger INPUT on the GPIO Socket
If you
- are using the GPI operator (for defining trigger input signals),
- have set parameter Connector Type to GPIO,
the values of parameter Pin_ID address the following pins:
Usage of IN pins on GPIO socket
The input (GPI) pins of the GPIO are configurable. You can configure the four input pins to receive either:
a) 4 single-ended signals pull-up,
b) 4 single-ended signals pull-down,
c) 2 differential signals pull-up, or
c) 2 differential signals pull-down.
To configure the input pins on the GPIO socket for a specific signal type (differential or single-ended), you have two modes available:
- Mode “Single-ended“ (providing options a and b)
- Mode “Differential” (providing options c and d)
Default mode for the GPIO is mode „Single-ended" (pull-up). How to switch modes, see Configuring the Physical Properties of Trigger Signals.
Usage of pins A1 / A2 (PIN_IDs 2/3 ) and pins B1/B2 (PIN_IDs 0/1) as single-ended or differential signals

In default configuration, the GPIO pins of the GPIO socket (rear side) offer:
If you need another configuration of the input signals, i.e.:
you can easily configure the GPIs according to your needs. For configuration, you use a command line tool which has been installed on your system together with the Silicon Software runtime. For more information, see Input Configuration and Configuring the Physical Properties of Trigger Signals. |
