Take
There are two kinds of ‘Take’ buttons that can appear on buttons of the panel (other than the
large fixed ‘Take’ button at the lower right).
• Take Primary
• Take Secondary
Each of these buttons takes a subset of what is armed to program output. An example of a
primary function is the A/B mixer. An example of a secondary function is a DSK.
For more information about the primary and secondary subsets, refer to the Imagestore 750
User’s Guide.
Take Primary
A ‘Take Primary’ button transitions the primary subset of the panel’s armed functions to
program output.
Take Secondary
A ‘Take Secondary’ button transitions the secondary subset of the panel’s armed functions to
program output.
GPI
GPI means “general purpose interface.” A GPI output port lets you control an external device. A
GPI input port receives a signal from an external device.
The iMC-Panel-100 has a GPI/Alarm connector at the rear that provides 2 relay outputs (with NO,
NC, and COM terminals) and 2 optically isolated TTL-level inputs. The 2 relays can control
external devices. The inputs can sense external events in your system.
There are 3 GPI button types that can be present on your iMC-Panel-100:
Any GPI button will have a legend assigned by the configurer. All GPI buttons are green.
S A iMC-Panel-100 configuration does not allow any GPI port to be represented by more than
one button.
GPI Output
A GPI output button is a toggle: when it is deselected, the associated relay’s “normally open”
circuit is open. When it is selected, the relay’s “normally open” circuit is closed. (When a GPI
output button is selected, it is high-tally.)
GPI Input
A GPI input button displays the state of a GPI input (panel or MCPM/MCE). There are 2 options:
• The button is low-tally when the associated GPI input is active (current flowing).
• The button is high-tally when the associated GPI input is active (current flowing).
GPI input Displays status of one of the 2 inputs on the iMC-Panel-100.
GPI output Controls one of the 2 relays on the iMC-Panel-100.
Combined GPI input
and output Displays status of one input (iMC-Panel-100 or MCPM/MCE) and controls
one output (iMC-Panel-100 or MCPM/MCE).
