S GPI C
ENDING OMMANDS
A special macro command allows you to send GPI signals to external devices and
systems via network-connected GPI interface devices (such as the eBOX™ from
JLCooper Electronics).
GPI macro entries are formatted as shown below:
Delay (ms)
####

Delay – the interval, in milliseconds, between the time when the command on
the prior line (if any) was issued to the system, and execution of this line.

Shortcut – Use the entry "gpi" in this field to send a GPI signal.

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:
Delay (ms)
500
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.
