DMC-1700/1800
For the DMC-1800 there is a separate LSCOM and INCOM for IN1-IN8, home, and limit switches for axes 1-4 and
for IN9-16, home, and limit switches for axes 5-8. The jumpers are located on the DMC-1800 at JP3 and JP13,
respectively.

Note: The DMC-1700 controllers with 5 or more axes have IN9 through IN16 also connected to INCOM. The
DMC-1800 controllers have a separate INCOM (labeled INC) for IN9 through IN16.

Using an Isolated Power Supply
To take full advantage of opto-isolation, an isolated power supply should be used to provide the voltage at the input
common connection. When using an isolated power supply, do not connect the ground of the isolated power to the
ground of the controller. A power supply in the voltage range between 5 to 24 Volts may be applied directly (see
Figure 3-2). For voltages greater than 24 Volts, a resistor, R, is needed in series with the input such that
