USER MANUAL
The standard configuration of the AEN signal is TTL active high. In other words, the AEN signal will
be high when the controller expects the amplifier to be enabled. The polarity and the amplitude can be
changed if you are using the ICM-1900interface board. To change the polarity from active high (5
volts= enable, zero volts = disable) to active low (zero volts = enable, 5 volts= disable), replace the
7407 IC with a 7406. Note that many amplifiers designate the enable input as ‘inhibit’.

To change the voltage level of the AEN signal, note the state of the resistor pack on the ICM-1900.
When Pin 1 is on the 5V mark, the output voltage is 0-5V. To change to 12 volts, pull the resistor pack
and rotate it so that Pin 1 is on the 12 volt side. If you remove the resistor pack, the output signal is an
open collector, allowing the user to connect an external supply with voltages up to 24V.

The reset is a TTL level, non-isolated signal and is used to locally reset the DMC-13X8 without
resetting the PC.

The firmware of the controllers allows unused auxiliary encoder inputs to be used as general purpose
inputs. These buffered inputs give an additional 2 inputs per unused auxiliary encoder input. On a
four axis controller, these inputs can be queried using @IN[81] - @IN[88]. Hardware connection of
these inputs is made through the A and B channels of the corresponding auxiliary encoder axis.
