HUDDLEVU BEHAVIOR
Power up the system via the power switch located on the AC side of the HV-CTL Control Unit. The Green
LEDS on the Table Boxes (referred to as "TB" from this point on) will fl ash for approximately 3 seconds and
then turn off. The system is now in the IDLE state and is ready to accept switch inputs/presses from the table
boxes. Note that the monitor and HDMI switchers are not yet turned on and no switch inputs are honored
while the LEDs are fl ashing.
From the IDLE state, press any one of the available switches on any of the TB's to activate the system. The
monitor and HDMI Switcher(s) will be immediately powered ON and all TB Green LEDs will fl ash for a
short time to indicate the system is powering up. Upon release of the selected switch, the selected switch’s
corresponding Green LED will fl ash at a fast rate for a short duration before turning steady green (to indicate
that particular selection was recognized). All other TB LEDs remain Red and the HDMI source from that
input is selected and is routed to the monitor. While the green LEDs of the selected input switch are fl ashing,
no other switch selections are honored. The unit is now in the ON state and is ready to accept additional
switch presses allowing the users to switch their source's program material to the monitor. (There is no
unconnected state for the HDMI switchers.)
Subsequent switch presses on any of the TB switches for less than 3 seconds will select that TB's source and
display it on the monitor. The Green LED will fl ash at a fast rate for a short duration to indicate the selection
was recognized, all other TB LEDs will go Red upon release of the switch. While the green LEDs of the
selected input switch are fl ashing, no other switch selections are honored. The unit remains in the ON state.
To return the system to the IDLE state: Press and hold any switch for a duration of greater than 3 seconds.
The monitor and HDMI switcher(s) will be switched OFF at the 3 second mark, all TB Red LEDs will fl ash
Red for a short time (approximately 3 seconds) and then all TB LEDs will be turned off indicating a return to
the IDLE state.
LOCKING/UNLOCKING SWITCH INPUTS
The user may wish to lock a specifi ed switch input(s) from recognition. This may only be done via the
appropriate LOCK command issued via the serial interface available through User Serial Port 2. (See
command description below.)
Once a switch input is locked, the corresponding LED of locked input will fl ash RED for a short duration and
then go out signifying the switch input will no longer respond to presses. Any other switch inputs also locked
will also fl ash their corresponding LED RED in unison.
In the event the switch input that is locked is also the currently selected source input then the LED will
fl ash RED for a short duration as above but then return to the GREEN status, indicating the source remains
selected.
The user may restore switch input recognition of any locked input by issuing the UNLOCK command for the
specifi ed input. Any switch inputs remaining locked will fl ash RED for a short duration and the specifi ed
unlocked input’s LED will return to its lit status of RED, if not the currently selected input, or will remain
GREEN, indicating it remains as the currently selected source input.
