Mode "Differential"
In mode “Differential”, all the four input pins of the GPIO are configured to receive differential signals:
- Pins A1/A2 -> 1 differential signal
- Pins B1/B2 -> 1 differential signal
Differential Signal on Pins A1/A2 (GPI 2 / GPI 3):
- If you use pins A1 (GPI 2) and A2 (GPI 3) for one differential signal, you have to set the value Pin_ID of the receiving GPI operator instance (in VisualApplets) to Pin_ID = 2.
- Don’t use any GPI operator instance with Pin_ID = 3, since the incoming signals in this case are undefined.
Differential Signal on Pins B1/B2 (GPI 0 / GPI 1)
- If you use pins B1 (GPI 0) and B2 (GPI 1) for one differential signal, you have to set the value Pin_ID of the receiving GPI operator instance (in VisualApplets) to Pin_ID = 0.
- Don’t use any GPI operator instance with Pin_ID = 1, since the incoming signals in this case are undefined.
Usage of pins A1 / A2 (PIN_IDs 2/3 ) and pins B1/B2 (PIN_IDs 0/1) as single-ended or differential signals
