Connecting to an External Device
GPI Connection ([GPI] Connector)
A GPI (General Purpose Interface) device (GPI controller, etc.) can be connected to the rear panel [GPI] connec-
tors to enable the transfer of a variety of control signals. Optional CP4SW, CP4SF, and CP1SF Control Panels
can be also connected via GPI.
The DME Satellite features 8-port GPI input and 4-port GPI output. The +V terminals have an output voltage
of 5 volts. The IN terminal detects voltage changes from 0V to 5V. The OUT terminals output either signal "L"
or "H" at a TTL level.
The parameters for each GPI input and output are assigned via the DME Designer application.
Euroblock connectors are used for all GPI input and output connections. Euroblock connection methods are de-
scribed in "Euroblock plug connection" on page 28 in this manual.

• For more information on the CP4SW, CP4SF, and CP1SF Control Panels, refer to the CP4SW/CP4SF/ CP1SF Owner's
Manual.
• You can use DME Designer to set up the system so that scene recall operations and User Defined parameter control can be
carried out from connected GPI control devices. Refer to the DME Designer Owner's Manual for details.
