Mode "Differential" (Default)
In mode “Differential” (default), all the six input pins of the Front GPIO are configured to receive differential signals:
- Pins 8/9 -> 1 differential signal
- Pins 11/12 -> 1 differential signal
- Pins 13/14 -> 1 differential signal
Alternatively, you can use pin pair 8/9 (in mode “Differential) for receiving one single-ended signal:
- Pin 9 -> 1 single-ended signal
- Pins 11/12 -> 1 differential signal
- Pins 13/14 -> 1 differential signal
Individual Pins in Mode “Differential”
Pins 11 and 12:
- The incoming signals on pins 11 and 12 are interpreted as one differential signal (pin 11 with the +, pin 12 with the - value).
- To receive this differential signal within VisualApplets, use a GPI operator instance with Pin_ID = 0.
Pins 13 and 14
- The incoming signals on pins 13 and 14 are interpreted as one differential signal (pin 13 with the +, pin 14 with the - value) .
- To receive this differential signal within VisualApplets, use a GPI operator instance with Pin_ID = 1.
Pins 8 and 9
- The incoming signals on pins 8 and 9 are interpreted as one differential signal (pin 8 with the +, pin 9 with the - value) .
- To receive this differential signal within VisualApplets, use a GPI operator instance with Pin_ID = 2.
Alternatively, you can use pin pair 8/9 for receiving one single-ended signal (although in mode “Differential”): In this case,
- you connect the single-ended incoming signal to the physical pin 9.
- To receive this single-ended signal within VisualApplets, use a GPI operator instance with Pin_ID = 3.
