Introduction
The XTBA F451 DMX fire effect unit is designed as a stand-alone DMX unit or can
also be used in conjunction with an existing DMX control system either in merge or
replace mode. The F451 generates two hundred thousand random levels every
second to provide ‘randomness’ to the output and can have a block of up to 250
random channel levels set. The output can be proportional or hard locked.
Controls for maximum and minimum level, flicker rate, start address and block
length allow for easy integration into an existing control system or as a stand-alone
system. The F451 can store up to eight setting memories and the unit itself will
retain the existing settings when powered down.
The F451 has a simple five button control and will provide ‘hours of fun for young
and old alike’ or alternatively is cheaper than setting fire to the 007 stage (again).
Operation:
FUNCTION BUTTON
FUNCTION Button Menu Loop – Pressing the Function button will take you around
the menu loop as follows:
FLICKER RATE
START ADDRESS
BLOCK LENGTH
RANDOM
ON/OFF

Pressing the right hand side UP and DOWN buttons will change the random rate.
The range is 1 to 100. The F451 generates 200K random levels every second and
the rate control alters the number of times the DMX output is loaded with the
random words. Pressing both the up and down keys will set the rate to 50.

Using the UP and DOWN buttons will change the DMX start address the random
channels are merged or replaced with.
If the start address is set so random levels are being lost e.g. beyond channel 512
(e.g. start address 280 with a block length of greater than 233) the screen will
change to warn that channels are being lost:

Using the UP and DOWN buttons the number of random channels transmitted can
be altered. The F451 can transmit up to 250 random levels in 512 DMX channels.
