Double-click the GPIO Command on the Template Timeline to edit its properties in the Object window:
Device Supported device names are:
 DB9M – Represents the internal GPIO device, available through the DB9
socket on the back of the machine.
 410E – Represents the optional Sealevel 410E device that allows GPIO control
over Ethernet.
 VBI – Represents the virtual GPIO device that does GPIO-over-VBI on the
video output(s) of the associated nexos channel. Alternatively, real device
names VBI0, VBI1, VBI2, etc. can be used to explicitly address the GPIO
devices dedicated to channels 0, 1, 2, etc.
Note that GPIO devices must be defined in the nexos-gpio-params.txt file in
order to use them here. In case of VBI devices, only the real devices VBI0,
VBI1, etcetera should be defined.
Output pin The number of the GPIO output pin to be manipulated. The first pin is 1.
Value Supported values are:
 0 – Disables the pin, a logical 'off' or 'low'.
 1 – Enables the pin, a logical 'on' or 'high'.
