EMBER+ VIRTUAL GPIO
V6.0 onwards adds 256 Virtual
GPIs and GPOs, available over the
Ember+ protocol.
Virtual GPIO can control and respond to
all functions that have been available to
traditional physical GPIO. This includes
triggering AutoFaders, Channel Cut and
PFL, Talkback, Tone, and responding to
Mic Open Systems, Fader open and/or on,
and On Air Protection status.
On accessing >Hydra2 Settings>GPI
or >Hydra2 Settings>GPO the user is
now presented with two GPI or GPO
sources, the normal GPI/GPO Lists
and the newly added Virtual GPI/GPO
Ember+ GPIO ports.
Fig 1 shows the assignment of GP Inputs
to control console functions. Note the ‘All
Ember+ GPI off’ button and the individual
‘Status’ switches which allow the user to
set or clear GPI’s Manually.
Fig 2 shows the assignment of GP
Outputs to respond to console functions.
Note the test button is present on every
Virtual GPO output to manually trigger the
Virtual GPO signal.
Labels for each virtual GPI and GPO are
also available to Ember+. These labels
are editable by the Ember+ controller, and
reflected in the Apollo and Artemis UI.
Figs 1 & 2 both highlight the labelling of
the eight Virtual GPI ports and the three
Virtual GPO ports which have been edited
by the Ember+ controller.
Virtual GPIO has been tested with VSM
software version 16.1.1. Please contact
Calrec if you intend to use virtual GPIO
with any other control system.
