TTL Inputs

As previously mentioned, the DMC-3425 has 3 uncommitted TTL level inputs while the DMC-3415 has 7 uncommitted TTL level inputs. The command @IN, TI and TZ will read the state of the inputs. For more information on these commands refer to the Command Reference.

The reset input is also a TTL level, non-isolated signal and is used to locally reset the DMC-3425 without resetting the PC.

Analog Inputs

The DMC-3425 has 2 analog inputs configured for the range between –10V and +10V. The inputs are decoded by a 12-bit ADC giving a voltage resolution of approximately .005V. The impedance of these inputs is 10Kohms. The analog inputs may be read using the @AN[n] function, where n is the number of the analog input to be read.
