Congratulations! You have now successfully
completed the installation of your EqualizerTM
board!
NOTE: The Equalizer board can be used with
either the Viking or Excalibur markers. The
Equalizer detects which marker it is installed
in, and adjusts parameters to handle the
differentfiringsequencesandeyesmodes.
SECTION 2 – USAGE
The EqualizerTM has numerous features,
which can be a bit overwhelming to those
that are not use to having so much
flexibility.
The Boot Sequence
WhentheEqualizerTM bootsup,theLEDwilllight
up orange and then either green (NORMAL
mode)orred(COMPETITION mode).
Feature Descriptions
Dwell
Dwell is the amount of time that the
solenoid will be activated. This time is
measured in milliseconds (1/1000th of a
second). The user can alter the Dwell only
when in NORMAL mode. In COMPETITION
mode, it is not possible to change settings
via the trigger programming. The factory
default is 8.0ms. Changes can be made in
.1ms units via the Equalink.
Increasing your Dwell will increase the
velocity of your marker. If you are
experiencing a great variance in your
chrono results, try increasing your Dwell.
If your dwell is too low, consistency will
suffer greatly.
Debounce
Debounce is the amount of time the trigger
switch must be stable in the up position
before checking for another trigger pull.
This time is measured in milliseconds. The
user can alter the Debounce only when in
NORMAL mode. Possible values are from
1ms to 255ms. The factory default is 10ms.
Changes are made in 1ms units.
If you find that your marker is double firing,
increase the Debounce time. To make your
marker fire faster due to being more

responsive to the trigger, decrease the
Debounce time.
Remember, if you pull the trigger once and
the recoil causes your marker to fire again
byitself, itis NOLEGALfortournamentplay
and is a SEVERE SAFETY HAZARD!
Eye Mode
The Eye Mode is can be set to one of four
different modes for the VikingTM:
Bypass - The anti-chop system is disabled.
When this occurs, the maximum rate of fire
is limited to 13 balls per second to help
prevent chopping of balls in the breech.
Delayed – This is like the normal method
of firing used in the original Intimidator
selectfireand semi-only boards. Ifyoupull
the trigger and noball is found in the
breech within ¾ of a second, the marker is
fired anyways. If a ball is found before the
time expires, the marker will immediately
fire(beforethe ¾ofsecond timeisup). This
isthedefaulteyemode.
Forced – In this mode, the marker will not
fire unless there is a ball in the breech. In
this mode, your marker will not “dry fire”
ever. Thisis the recommended eye mode.
Simulate – In this mode, a ball is simulated
to be in the breech. This allows you to fire
themarkerwithjustair,atthefullspeed that
the marker is capable of firing! This mode
can be used for practicing trigger pull
methods, without wasting paint. DO NOT
SHOOTPAINTINTHISMODE!
It is highly recommended that tournament
players use the Forced mode. Ifyou have
a hopper jam or something hangs up in the
feed tube, and you are using Delayed
mode, it is possible to chop a ball if one
breaks free at the instant the firing
sequence starts. Although this is not
common, this does happen enough to
justify the creation of this mode. The
factory default is Delayed.
The Eye Mode can be set to one of four
different modes for the Excaliburâ:
Bypass - The anti-chop system is disabled.
When this occurs, the maximum rate of fire
is limited to 10 balls per second to help
prevent chopping of balls in the breech.
Normal – In this mode, the chambered ball
willfire (ifthereisone)andtheboltwillopen
forupto ¾of asecondbefore automatically
closing. If a ball is found before this time
expires, the bolt will immediately close.
Thisisthedefaulteyemode.
Classic – In this mode, the chambered ball
willfire(if thereis one),andtheboltwill stay
open as long as you keep holding the
trigger (just like a stockAutococker).
Sniper – In this mode, the chambered ball
will fire (if there is one), and the bolt will not
cycle until you release the trigger. When
the trigger is released, bolt will open for up
to ¾ of a second before automatically
closing. If a ball is found before this time
expires, the bolt will immediately close.
NOTE: IN ALL CASES, IF YOU DO NOT
HAVE AN EYE SYSTEM, THE COMPUTER
WILL AUTOMATICALLY SWITCH TO
BYPASS MODE!
HopperTrigger
The EqualizerTM hardware has the ability to
generate a positive or negative going
pulse, for a duration that is user
programmable. Although the EqualizerTM

cannot supply power to your hopper to run
it (in place of its own batteries), it can
provideatrigger that could forceactivation
for a programmable period of time. More
information about the interface to the
EqualizerTM will be provided in separate
documentation. Possible values are .1 to
2.0 seconds, with either a positive or
negative going pulse. The factory default is
positive pulse, lasting 1.0 second. This
configuration was designed to work
directly with the Warpfeed from Air Gun
Designs. Changes to these parameters
require the Equalink cable.
LED Colors and Meanings
The LED is a type that can light up in one
of 3 different colors. The EqualizerTM uses
this to indicate to the user when certain
events are occurring. This is a breakdown
of what the LED states represent:
•Solid Green - In or entering
programming mode.
•Blinking Green - Normal operation,
anti-chop system is enabled.
•Blinkin g Orange - Normaloperation,
anti-chop system is disabled.
•Blinking Red - Battery is low.
•Red/Green toggle - There is an error
with the anti-chop system.
GeneralUsageTips
The LED boot sequence is as follows: solid
orange (booting), solid green (normal
mode) or solid red (competition mode
You can manually bypass the anti-chop
system by moving the bolt forward
(blockingtheinfrared beam)and pullingthe
trigger3times. When the anti-chopsystem
is bypassed the LED will blink orange
(instead of green).
The first two times you pull the trigger, the
LED will toggle red/green to let you know
that an error occurred with the anti-chop
system. If a shell fragment entered the
breech,itcould beclearedon thenextshot.
Thus, disabling the anti-chop system
immediately on the first problem is
somethingthatthe EqualizerTM does notdo.
Withaneye system,the rateoffire islimited
only by how fast the pneumatics will cycle,
how fast you can pull the trigger, and how
fast your loader can feed your marker.
Because the EqualizerTM can easily exceed
the feed rate of standard agitated hoppers,
it is recommended that you use an
advanced hopper (TurboRev equipped
Revolution) or a force-feed type of hopper
for the best possible performance.
While in programming mode, the marker’s
ability to shoot is completely disabled.
TournamentLock
It is possible to put the EqualizerTM into a
tournament lock (COMPETITION) mode.
You can do this by making sure the power
switch is in the off position, grounding
(connecting) the two center pins on the
Equalink interface connector, and then
moving the power switch to on position.
Each time you ‘reboot’ with the pins
grounded, the NORMAL and
COMPETITION modes will toggle. The
markerwillnot firewiththe jumper inplace!
Removing the jumper will allow the normal
operation of the marker.
Programming the Dwell, Debounce, and Eye
ModeUsingtheTrigger
The Dwell, Debounce, and Eye Mode
functions are programmable by following
these instructions:
Make sure the power switch is on the off
position. During programming, make sure
that your marker has a barrel condom in
place or the air supply shut off. Although it
is not possible to fire the marker while in

programming mode, it is always good to
practice safe marker handling.
Pull the trigger, and hold it in the back
position. Now, turn the power switch to the
on position. The LED will light green. Now,
immediately release the trigger. The LED
will light red.
Pulling and releasing the trigger will toggle
the LED color between red, green, and
orange.
Red indicates you are in the Dwell
programming mode, green indicates you
are in the Debounce programming mode,
and orange indicates you are in the Eye
Mode programming mode. Once you have
reached orange, an additional trigger pull
willstartthe sequence ofcolors over again.
This is also known as the “programming
starting point”.
When you decide which programming
mode you want, pull the trigger and hold it
until the LED goes out and then release the
trigger. There willbe a 2secondpause,and
then the LED will flash the same color of
the programming mode you are in
(red=Dwell, green=Debounce, orange=eye
mode).
For the Dwell and Debounce programming
modes, each flash represents 1ms
(millisecond) of time. For example, if you
were programming the Dwell and the
settings were the default, you would see
theLED flashred 8timesinarow,indicating
the dwell is set to 8ms. The flashing of the
LED shows you the current setting before
you program it.
For the Eye Mode programming mode, the
total number of flashes represents the
mode of the anti-chop system.
Dwell and Debounce
Once the LED stops flashing, you can now
pull and release the trigger once for every
1ms of time you want the setting to be. For
example, if you were programming the
Debounce for 5ms, you would pull and
release the trigger 5 times. On each pull of
the trigger, the LED will light up (indicating
thatthepull hasbeen detected). Ifyouhave
decided not to program this mode, simply
do not touch the trigger for 5 seconds. The
LED will toggle green/red alternately to
indicate there was a programming error,
and then go back to the programming
starting point.
Eye Mode
Once the LED stops flashing, you can now
pull and release the trigger the number of
times necessary to set the Eye Mode.
The following is a list of the possible Eye
Modes and the flashes (also trigger pulls
required):
•1 flash – Bypassed mode (for
Viking and Excalibur)
•2 flashes - Delayed mode (Viking)
or Normal mode (Excalibur)
•3 flashes – Forced mode (Viking)
or Class mode (Excalibur)
•4 flashes - Simulate mode (Viking)
or Sniper mode (Excalibur)
Ifyoupull and releasethetrigger morethan
4 times, then the LED will toggle green/red
alternately to indicate there was a
programmingerror, andthengo back tothe
programming starting point.
Programming Complete
Once you pulled and released the trigger
the number of times necessary to set the
function, wait a few seconds. The LED will
flash red/green/orange in rapid succession
(numerous times) to let you know that the
new setting has been saved. After this, the

LED will return to the color representing
what the current programming mode is. At
this point, you can once again press and
releasethetrigger to toggle betweenDwell,
Debounce, and Eye Mode programming
modes.
You can perform a complete reset of the
Dwell, Debounce, and Eye Mode to the
factory defaults when you are in the
program starting point (where you can
toggle the programming mode).
To do this, just hold down the trigger for 5
full seconds. It does not matter what
programming mode you are currently in
(Dwell, Debounce, or Eye Mode). The
LED will start flashing red, letting you
know that a reset operation is being
performed. After this occurs, you will be
back to the programming starting point.

V. MAINTENANCE.
A.CLEANING.
Aclean marker is a happy marker.Thebarrel
ontheEXCALIBUR®andVIKING™can be
cleanedduringagamebyeitherunscrewing
thebarrelfromthemarker or by removingthe
boltandswabbingthroughthe marker andthe
barrel.
Theboltcanbefield-strippedfromthe
EXCALIBUR®andVIKING™while the
markerispressurizedwithgas.Thisallows
youtocleanthemarker and oiltheboltwhen
needed.
TheExcalibur®and VIKING™shouldbe
cleanedexternallyusing acottoncloth.
Allexternaland internalmovingpartsshould
belubricatedusinglightsynthetic oilonly. Oil
can be added by placing a few drops in the
inputquickdisconnectonthe
SIDEWINDER®(patpend)regulatorand then
dryfiringthegun.Afew drops should alsobe
placedontheo-ringsonthe Lightning bolt.
This should be done every time you play,
and the bolt should be oiled throughout
the day of play.
Recommendedlubricants:Extreme-lube from
AKALMPorPalmerPursuitspaintballgunoil.
Under no circumstances should you use
Vaseline, WD-40, Grease of any kind (ie.
NO DOW 33), Engine Oil, 3-in-1, gun oils,
and any similar oils. If you have a
question about the type of paintball gun
oil you are using e-mail us.
