Variables
Matrix switches in Control4 have a standard set of VI EO_OUTPUT_xx_INPUT variables
which are populated to show which input is connected to which output. These are
updated by the driver as irector switches the matrix. In order for these variables to be
updated if a change is made directly on the switch or via IR then you must enable Query
for Switch Status in the driver properties or execute a device specific command to
update them.
In addition a number of other variables are populated and you can program on the event
of any of these changing.
INPUT_x_STATE True if the switch senses an input (source) device is powered and
connected to the switch. In order for these variables to update you
must either enable Query for Connection Status in the driver
properties or execute a device specific command to update them.
OUTPUT_x_STATE True if the switch senses an output (sink) device is powered and
connected to the switch. In order for these variables to update you
must either enable Query for Switch Status in the driver properties or
execute a device specific command to update them.
E I _x_STATE This will be set either to ‘Fixed’ or ‘Output 1’ depending on the
settings on the HX-88. In order for these to update you must either
enable Query for Connection Status in the driver properties or execute
a device specific command to update them.
Actions
The driver supports the standard Connect and isconnect commands for each output. In
addition the following evice Specific Commands are also provided.
Set E I This allows you to set the E I for an input either to the Fixed
standard E I or to copy it from Output 1
Get Input/Output Status This command interrogates the switch to find the current input
to output settings. This information is then used to update
Control4. This is useful to ensure that Control4 is periodically
aware of any manual switches that have been made on the
unit.
Get connection status This command interrogates the switch to see which Inputs and
Outputs are connected and powered. It updates the driver
variables associated with this feature.
Get E I status This command interrogates the switch to report the E I
setting on each of the inputs. It then updates the driver
variables associated with this feature.
