Using GPI (General Purpose Interface)

Using GPI (General Purpose Interface)
PM1D system software V1.5 allows you to use GPI (General Purpose Interface).
The PM1D system engine (DSP1D-EX{DSP1D}) and console (CS1D) have a D-sub 25-pin GPI (General Pur-
pose Interface) connector. This GPI connector combines both GPI IN and GPI OUT, and allows eight chan-
nels of control signal to be input and output simultaneously for communication with an external device. For
the pin configuration, refer to page 69 of the CS1D Reference manual (Appendices).
The GPI OUT connector is an open collector out-
put. Also GPI IN is pulled-up at 5 V. The power
supply pins must be used at less than MAX 160 mA,
and the GPI IN/OUT pins at less than MAX 40 mA.
The following diagram is an example of using GPI to
create external switches and indicators for them.
You are free to specify how the PM1D system will oper-
ate when control signals are received from GPI IN, and
which operations on the PM1D system will cause con-
trol signals to be transmitted from GPI OUT.
By connecting a GPI-compatible external device or a
customized external switch etc. to the GPI connector,
you can cause an external device to start running when a
fader is operated, or use an external device to remotely
control talkback operations or select monitor sources.
When using the PM1D system in Mirror mode,
only the currently selected engine can use its GPI
IN connector. Also, the output from the GPI
OUT connector is always linked for engines A
and B.
When using the PM1D system in Dual Console
mode (p.11), only the currently-operated con-
sole can use its GPI connector. You cannot
change the settings of the other GPI connector, or
receive control signals from the other GPI con-
nector. Also, settings for the GPI connector of the
engine can be made only on console 1.
