17.8.3 SENDING GPI COMMANDS
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) Shortcut Value Key 1 Value 1 etc.
#### gpi name GPI_pin# boolean

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) 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 cases, 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.
