
Key # (0 – n) – The value you enter in this field identifies a target pin on the external DVI
device to receive a signal defined in the following field. The entry should be formatted
as “pin#” (e.g., “pin1”, without quotation marks).

Value # (0 – n) – This value controls the contact closure state (on or off) for the GPI
device pin identified by the preceding key. The value can be entered variously as “1” or
“0” , “on” or “off”, “true” or “false” (without quotations).
A typical entry might look like the following:
Delay (ms) Shortcut Value Key 1 Value 1 etc.
500 gpi jlcooper pin12 1
Hint: Multiple GPI pins can be targetted simultaneously by key/value pairs entered on a
single line.
Alternatively, some GPI devices require a GPI ‘pulse’ of a specified duration. In such a case, you
might send an “on” command on one line, followed – after a suitable delay – by an “off”
command sent to the same pin.
17.9 EDITING MACROS
Often you will wish to modify values assigned to the various steps
in an existing macro, rather than re-recording it; or perhaps you
want to experiment with other possibilities. Click the Edit button to
open the Macro Editor for the currently selected macro.
