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.
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.
