GPI Connection
GPI (General Purpose Interface) device (GPI controller, etc.) can be connected to the rear-panel [GPI]
connectors. Using GPI a variety of control signals can be transferred between the DME64N/24N and external
controllers or other devices. The optional CP4SW, CP4SF, and CP1SF control panels are also connected via
GPI.
The DME64N provides 16 channels of GPI input and output, and the DME24N provides 8 channels. Each
input channel has an IN terminal and a +V terminal. Each output channel has an OUT terminal and a GND
terminal. The +V terminals have an open-terminal voltage of 5 volts. The IN terminals can detect a full range
of input voltages from 0V through 5V, while the OUT terminals output either 0V or 5V.
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
described in “Euroblock Connection” on page 35 in this manual.
NOTE
For more information on the CP4SW, CP4SF, and CP1SF control panels refer to “CP4SW, CP4SF, and CP1SF” in the
Appendix of this manual (page 59).
NOTE
The DME Designer can be used to set up the system so that scene recall operations and user parameter control can be carried
out from connected GPI control devices. Refer to the DME Designer manual for details.
NOTE
GPI connector calibration procedure is described on page 53 of this manual, in the Utility display GPI page.
