GPI Control
General Purpose Interface (GPI) is a high/low voltage
signalling protocol that allows the switcher to send
simple commands to an external device, or receive
commands from a device. Each pin on the GPI is set
as either high (+5 Volts), or low (0 Volts), and it is the
switching between high and low that sends commands
to the external device, or to the switcher.
GPI Trigger Types
There are four trigger types supported by the switcher.
These can be either output triggers, or input triggers.
Table 6: Trigger Types
Trigger Description
Low Edge The output level is set
high, and momentarily
goes low for the trigger.
High
Edge
The output level is set
low, and momentarily
goes high for the trigger.
Low
Level
The output level toggles from
the base high level to the
low level. The output signal
remains at this level until reset.
High
Level
The output toggles from
the base low level to the
high level. The output signal
remains at this level until reset.
GPI Setup
Each GPI pin on the switcher can be configured as
either an input, or an output. By default, all GPIs are
set as inputs.
To Set Up a GPI Input
The switcher requires a Low Edge GPI input trigger.
1.
Press MENU > Config > GPIO . Click
Navigation Menu > Configuration > GPIO .
The page lists all the GPIs on the switcher and
how they are currently configured.
2. Use the GPIO knob to select the GPI that you
want to configure as an input. Click Edit for the
GPI that you want to configure as an input.
3. Use the Type , or I/O , knob to select GPI . Click
GPI .
4.
Press the Edit knob.
5. Use the Event knob to select the action you want
to assign to the selected GPI input pin. Click an
Event button to select the action you want to
assign to the selected GPI input pin.
