Value – The shortcut value is the name of the GPI device (defined earlier in gpi_setup.xml) that you
want the signal defined on this line to address.
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:
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.
