GPI Buttons
Two user-configurable buttons, GP I1 and GPI 2 , ( Figure 2-9 ) allow control of
MMCP functions and output relays and responses to opto-isolator inputs.
The buttons and functions are associated with the 12 GPI relays on the rear
of the M–2100 frame. Four GPI input relays are also provided on the rear of
the frame and can be configured as opto-inputs to trigger an M–2100 action
such as a cut or transition.
When pressed, the GPI button high tallies. If a GPI button is not configured
for one of the activities described below, pressing it has no effect, and
results in a warning beep.
GPI button presses are ignored unless in the qui-
escent state.
Figure 2-9. GPI Buttons
The GPI buttons can be configured to perform one of the following actions
when the assigned button is pressed:
■ Assign an output relay ( GPI Outputs 1–12 ) to perform a programmed
action, or
■ Arm opto-inputs (trigger a programmed M–2100 action from GPI Opto-
inputs 1–4 ).
These parameters are configured in the GPI form in the Configuration
Manager application described in the Installation and Service Manual.
