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.
GPO 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 Fader Start (FDR
START); F KEY; Talkback Output (TB OUTPUT); VIRTU-
AL GPO; Channel Mute (CH MUTE).
GPO Parameter
Used to assign addition-
al 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 generat
-
ed - the relay contacts stay in their new position). It is
suggested 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’.
