6. Panel is configured in the virtual display and
connected but running incompatible firmware:
Go to the "Fixture & Firmware Library" (see
"Updating and reloading P3-100 firmware" on
page 46) and make sure the current panel firmware
is set to a version which is compatible with the
current P3-100 firmware (1.x.x panel firmware is
compatible with 1.x.x P3-100 firmware and 2.x.x
panel firmware is compatible with 2.x.x P3-100
firmware).
Correct the current firmware in Fixture & Firmware
Library, if necessary, then update firmware of
panel(s) by clicking the "Update All Devices" button.
7. Panel is configured but is currently being
controlled by another P3 controller:
If the other P3 System Controller is connected to
panel(s) by mistake, disconnect it to regain
control over panel(s).
If the other P3 System Controller is running the
same configuration, and receiving the same video
input, the P3-100 you are looking at is effectively
acting as a backup for the other P3 System
Controller. It will take control over the panel(s) if
the other P3-100 is powered off or crashes.
