The programmable GPOs are used to trigger alarms or to provide a limited tally capability. The GPOs
will be in the de-energized state when the power is off, so all the contacts will be closed.
Once the GPO is enabled through the Web page (Section 6.8.2) or VistaLINK® (Section 7.8.2), the
orientation can be changed from Normally Open to Normally Closed.
Also, the GPOs can be individually encoded to work independently or collectively:

Individual Function:
The four GPOs can be triggered independently, depending on the selected
function assigned to a specific GPO set, whether it is PSU Fault, Temperature Fault, Video Src
Missing and Video Route Selected (i.e.: in case, PSU Fault is attributed to GPO1, then once the
fault is present, GPO1 will be triggered, from 0 to 1).

Encoded Function:
The four GPOs can be encoded as a single integer value, identifying the
associated source of the destination set in the Web page or VistaLINK®. These bits of integer
value are identified as a source. A GPO value of 0000 Binary (GPO1 as the LSB) equated to
source 1 and a value of 1111 Binary equated to source 16.

NOTE: Each GPO correlates to two physical output pins – see Table 2-6 and
Figure 2-3.
