Digital Control Section
GPI
The PM5000’s rear-panel GPI port provides 3 input and
8 output channels for GPI pulse communication with
external equipment. One of the input channels controls
talkback on/off (same function as the TB [ON] switch).
One of the functions in this section determines whether
or not the remaining two input channels are active for
scene increment and decrement control. The second
function determines which of the 8 output channels are
used for fader start signal transmission and scene
linking.
Scene Inc/Dec (GPI In) (Parameter No. U21)
The GPI inputs can be used for sequential incrementing
or decrementing of the PM5000 scene memory from
external equipment. Scenes 010 through 999 can be
recalled using this capability, and empty “NO DATA”
scenes are automatically skipped. These settings are
maintained in the PM5000 setup memory.
Press [ENTER] after selecting the above display and a
display like the one shown below will appear. Use the
[INC] and [DEC] keys to select ON (GPI scene recall
enabled) or OFF (GPI scene recall disabled).
GPI Out (Parameter No. U22)
This function makes it possible to specify the GPI
outputs to be used for fader start control (a signal is sent
when a fader is raised above –60 dB or lowered to -
∞
)
and for scene linking. Although 8 GPI outputs are
provided so that these operations can be separated, it is
possible to assign control to the same GPI outputs. Fader
start settings are maintained in the console’s setup
memory and are common to all scenes, while scene link
settings apply to the current scene and are stored in the
scene memory via a scene store operation.
Press [ENTER] after selecting the above display and a
display like the one shown below will appear. Use the
[INC] and [DEC] keys to select either the FADER
START or SCENE LINK function for setup.
NOTE
Scene incrementing and decrementing via the GPI port is slightly
different from the way the panel [INC] and [DEC] keys function
in that incrementing and decrementing will always occur from the
current scene – the “temporary scene” that can be used with the
[INC] and [DEC] keys (page 69) cannot be used with GPI port
control. If the preview function is active and a GPI scene change
command is received, the preview function will be disengaged.
