1 [AC IN] Connector
This is the device's three-pronged AC power connector.
Connect to the AC mains using the supplied AC power
cord. See "Setup" on page 18 for details.
NOT E
Use the supplied AC cord clamp to prevent accidental
disconnection of the AC power.
NOT E
When connecting to two-prong type AC mains outlets use the
supplied plug adaptor.
Even when the power switch is turned off, electricity is
still flowing to the product all the minimum level. When
CAUTION
you are not using the product for a long time, make sure
to unplug the power cord from the wall AC outlet.
2 Ground Screw
The supplied AC power cable is a 3-wire type, so if the AC
outlet used is properly earthed the DME64N/24N will be
earthed as well. Hum and interference may by further
reduced in some cases by also connecting the earth screw
to an earth point.
NOT E
Connect the device to only one ground point.
Connecting the device to more than ground point can result in
ground loops that can cause increased hum and noise.

3 [GPI] Connector
This Euroblock connector provides access to the unit's GPI
(General Purpose Interface) interface for transfer of control
signals to and from external equipment. The DME64N
provides 16 channels of GPI input and output, while the
DME24N provides 8 channels. Each input channel has an
IN terminal and a +V terminal. Output channels each have
an OUT terminal and a GND terminal. The open voltage
at the +V terminal is 5V, while the IN terminal detects
voltage changes from 0V ~ 5V. The OUT terminals output
either signal "L" or "H" at a TTL level.
See "GPI Connection ([GPI] Connectors)" on page 33 for
connection details.
