FIREMASTER IV " MillenniumThree " radio shooting system User’s manual
RSSI Main shows a 58dBµV value. This parameter represents the field
intensity (at the antenna of the TX5000 Unit) of the radio signal received
from the Remote Unit. The measuring range spans from 0 to 80dBµV. When
the signal goes down to 20dBµV, the "WARNING" icon appears: the signal
is too low and some communication error could be encountered.
RSSI Unit shows a value of 67dBµV. This parameter represents the field
intensity (at the antenna of the Remote Unit RX48) of the radio signal
received from the Base Unit during the DATA REQUEST of the TX5000.
The measuring range and the details about the signal level are the same as for
the previous example.
SYSTEM shows a value of 12. 6V. This is the voltage of the battery
powering the whole SYSTEM (radio, microcontroller, peripherals, etc.) of the
Remote Unit checked. Should this voltage drop below 11.6V, the
"WARNING" icon will be displayed because the correct voltage level to the
system circuits could be no longer granted.
FIRE shows a value of 25.1V. This is the voltage of the batteries powering
the firing lines of the Remote Unit checked. Also in this case, should the
value drop below 23V, The "WARNING" icon will be displayed because the
necessary power level could be no longer available for the firing lines.
NOTE: when the "WARNING" icon appears, the system can
be still used as usually. One should anyway consider as the system is
working near to the lower limit of its possibilities and thus some
problems more or less severe could be encountered such as: firing failures, no
response from the Remote Unit, errors reading data, etc. Using the system
when the "WARNING" signal is ON, is fully under the responsibility of the
operator: he must evaluate if the show importance is worth the risk of
operating near to the safety limits.
IN ALL CASES THE SYSTEM ALWAYS GRANTS A SAFE
OPERATION AGAINST UNDUE OR PREMATURE FIRINGS.
3) The selected Remote Unit ANSWERS and data are displayed on the screen.
The selected line is connected to a series of 10 squibs with a total resistance
(squibs + cables) of 27 ohm, the SEQUENCE for that line is a timed one with
a delay of 12 seconds and 35 hundredths of second. Data will appear as
follows:
