Trigger INPUT on the GPIO Socket

If you

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:

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

 

 

Physical Interface - Default Settings and Configuration

 

In default configuration, the GPIO pins of the GPIO socket (rear side) offer:

  • 4 single-ended input signals in pull-up mode
  • 4 output signals

If you need another configuration of the input signals, i.e.:

  • Pull-down mode,
  • 2 differential signals (and no single-ended signals),

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.
