Trigger INPUT on the Front GPIO

If you

the values of parameter Pin_ID address the following pins:

 

The input (GPI) pins of the Front GPIO are configurable. You can use the six input pins to receive either:

a) 3 differential signals, or

b) 2 differential signals and 1 single-ended signal , or

c) 4 single-ended signals.

To configure the input pins on Front GPIO for a specific signal type (differential or single-ended), you have two modes available:

Default mode for the Front GPIO is mode „Differential“. How to switch modes, see Configuring the Physical Properties of Trigger Signals.

 

 

Usage of IN pins on Front GPIO

 

Physical Interface - Default Settings and Configuration

 

In default configuration, the GPIO pins of the Front GPIO offer:

  • 3 differential input signals or 2 differential and 1 single-ended input signal in pull-up mode
  • Two TTL output signals

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

  • Pull-down mode,
  • 4 single-ended signals (and no differential 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.
