TTL Inputs

As previously mentioned, the DMC-14XX has 7 uncommitted TTL level inputs. The command @IN,
or TI 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-14XX
without resetting the PC.

Analog Inputs

The DMC-14XX 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 are specified as @AN[n] where n is the number 1 or 2.

TTL Outputs

The DMC-14XX provides three general use outputs, an output compare and 4 status outputs.
The general use outputs are TTL and are accessible through the ICM-1460 as OUT1 thru OUT3.
These outputs can be turned On and Off with the commands, SB (Set Bit), CB (Clear Bit), OB (Output
Bit), and OP (Output Port). For more information about these commands, see the Command

the user to connect a load (e.g. optoisolator
or relay) between AMPEN and their own
