MENU > GPIO
Trigger Edge Select
Choose the triggered edge for this GPI pin.
Choose either Rising, Falling, or Both. If you choose 'Both' the {Polarity} field will become available.
Trigger Polarity Select
Set the Polarity of the input.
The encoder changes the polarity between positive and negative. This field is only available if the {EDGE} field is
set to BOTH.
GPI On / off
Enable and disable GPO functionality
Individual setting for each Pin.
GPO Function
Select the function to be assigned to the GPO pin.
Depending on the function selection, the {Parameter} field may or may not be available. For example, the Fader
Start (FDR START) function requires a channel assignment - set this using the {Parameter} field; the Talkback
Output (TB OUTPUT) function does not require any additional parameter. Available functions: Channel Mute Fad-
er Start (FDR START); F KEY; Talkback Output (TB OUTPUT); VIRTUAL GPO; Channel Mute (CH MUTE).
GPO Parameter
Used to assign additional values to functions where required.
Examples include channel number, virtual GPIO pin number, and so on.
Pulse Time
Set the Relay Pulse Time.
The relay contacts will revert to their original position at the end of the pulse time. The encoder adjusts the pulse
length in ms (a blank field means no pulse is generated - the relay contacts stay in their new position). It is sug-
gested that a pulse time is set only when the EDGE field is set to 'RISING' or 'FALLING. It is also suggested that no
pulse time is set when the EDGE field is set to 'BOTH'.
