Description
5, TTLIn0 ... TTLIn4
General purpose digital Input (for example for encoder
error signal). Other general purpose digital input
functionality, such as edge
functionality, etc., is not supported.
In NYCe 4000 Software these inputs are referenced
with the following definitions:
● Input TTLIn0 – referenced
NYCE_DIG5VIN0A
● Input TTLIn1 – referenced
NYCE_DIG5VIN0B
● Input TTLIn2 – referenced
NYCE_DIG5VIN0C
● Input TTLIn3 – referenced
NYCE_DIG5VIN1A
● Input TTLIn4 – referenced
NYCE_DIG5VIN1B
