DMX Operation
DMX Addressing
Push the tabs above or below the number window to
set the address. (Valid addresses range from 001 to
512.) The yellow light above the address block will
illuminate if a DMX signal is present.
Each 4Bank DMX ballast operates on 5
addresses.
This is useful in achieving light effects
like flickering, chasing or creating light patterns.
BAL-457
operates on 5 addresses:
Lamps
= 1-4
4ft/2ft
= 5
The 5th address controls the
4ft/2ft
setting.
Dimmer level from 0%~50% operates all the lamps
at the 4ft setting. Dimmer level from 50%~100%
operates the lamps in the 2ft setting and the overall
light output drops by ½ f-stop.
Note
: If the 5th address is not addressed, the ballast
will default in the 4ft setting. The
4ft/2ft
select setting
controls all 4 lamps equally. Individual settings per
lamp are not possible.
IMPORTANT!
The dimmer board/light console should have its channel set to LINEAR light
output response. (LINEAR response is the default setting on most dimmer
boards.)
Note:
If a Fixture or Ballast loses its DMX signal, it will hold its last
DMX command
. For this reason, it is important to turn a Fixture or Ballast
off using the DMX commands. For example, if you try to turn off the lights by
turning off the dimmer board, the lights will remember their last DMX com-
mand and stay on. The Fixtures or Ballasts require a DMX “Off” or “Black-
out” command in order to turn off.
