Power LED
The power LED illuminates blue whilst power is present within the unit. If this indicator
is not on, the most likely reason is simply the absence of mains power, but under fault
conditions it may also indicate a ruptured mains fuse or a problem with the internal power
supply module.
Light Control Buttons
The three light control buttons; Transmit (TX), Standby and Rehearse (REH) provide remote
controls for the Sonifex SignalLED range of studio signs, or similar device. The optically
isolated drivers and the open-collector tally outputs associated with the TX and REH
buttons are activated whenever the button LEDs are illuminated.
The TX button can be pressed at any time, regardless of the state of the other two light
controller buttons. If the REH button is active when TX is pressed, REH will be deactivated. If
the Standby countdown is currently active when TX is pressed, the countdown is cancelled
and both the Standby and REH buttons are deactivated.
The Standby button controls a 2 minute countdown where the TX and REH buttons
and their associated remote outputs ash alternately. To start the 2 minute Standby
countdown, which can only be initiated if the TX control is currently inactive, simply press
the Standby button. The button will illuminate white to show the countdown is active and
the TX and REH buttons will ash red and blue respectively for 0.5 seconds each. After the
2 minutes has elapsed, the Standby and REH buttons and associated remote outputs are
deactivated while the TX remains on.
The Standby countdown can be cancelled at any time during the 2 minutes by pressing the
Standby button a second time. The TX button will be deactivated and the REH button will
return to the state it was in prior to the countdown starting.
The REH button can also be pressed at any time, regardless of the state of the other two
light controller buttons. If the TX button is active when REH is pressed, TX is deactivated.
