1.4 THE FIRE BUTTONS.
These buttons are snap action dome switches under a sealed overlay. When the
transmitter is off, all indicators are dark, and no signals can be transmitted even
if a button is pressed. When it is on, no transmission occurs (after the initial
power-on reset transmission) while no buttons are pressed. If armed (not in
SAFE mode), continuous transmission occurs while “Next Fire” or a numeric
button is pressed.
Pressing a numeric button while in single-shot mode fires the corresponding
receiver output on the current channel immediately.
Depression of “Next Fire” while in single-shot mode fires the next receiver output
(indicated by the illuminated numeric LED). For example, if output 3 had been
fired last, LED 4 would be illuminated, and pressing “Next Fire” would cause
output 4 to fire. If output 12 had been fired last, LED 1 would be illuminated, and
pressing “Next Fire” would cause output 1 on the next sequential channel to fire.
Thus, “Next Fire” can be used to fire a series of sequential shots. Note that after
powering up the transmitter, output 1 will be the first receiver output fired by a
depression of the “Next Fire” button.
In single-shot mode, the current cue will continue firing until the transmitter
button is released. In auto-fire (machine-gun) mode, the transmitter will continue
firing cues sequentially at the selected fire rate until the “Next Fire” button is
released. After firing cue 12, the transmitter will wrap around to cue 1 on the next
sequential channel and continue firing from there.
Output firing pulses are stretched to a minimum duration of 0.6 seconds in the
receivers to ensure that all cues fire reliably, even when the fire buttons are
pressed for a shorter period of time. Note that it is not necessary to wait for the
completion of the 0.6 second firing pulse period before firing subsequent cues.
They can be fired as fast as the operator can press the button, provided that
each button depression lasts at least 0.1 second, followed by at least 0.1 second
with the button released. If many transmitters are transmitting simultaneously, it
may be necessary to depress a fire button slightly longer than 0.2 second in
order to ensure an output from the receiver.
