The BEII (Bonus Engine 2)

board is the primary commu-
nications piece linking the
machine to the server, as well
as to the NexGen (or VFD).
The NexGen is what stores all
the cool promotional mes-
sages that the customer sees.
The problem is that the BEII
and the NexGen are very
separate entities. The
NexGen has a much higher
ratio of visible failure, while
the BEII is usually the cause
of the more difficult to track
problems.
Page 18 Slot Tech Magazine June 2007
your communications numbers increase
back to 144.16.

Before you ever replace a BEII, I would rec-

ommend performing a hard ram clear. To
do this, you will need to remove power and
short C33 to ground for about 10 seconds.
This will wipe all information stored on the
BEII and you will have to reprogram it. If
this doesn’t clear up the problem, then I
would recommend a BEII swap.

Any promotional information displayed on

the NexGen is stored within the NexGen. If
a power outage occurs or you need to un-
plug the NexGen, you may lose this infor-
mation. This is usually caused by a battery
failure. This doesn’t mean the NexGen is
bad, simply that it needs to download all its
information again. I would recommend re-
placing the battery on the back to keep it
from doing this at every power outage. An-
other thing to remember is that these are
rechargeable batteries but the NexGen does
not recharge them. You may want to look
into a battery charging system.

When a NexGen displays the “Not Registered”

message, this means there is a conflict in
the system. Either the BEII has no informa-
tion, or the wrong information. If you insert
your employee card, it should give you a
message, such as “NO ASSET” or “DUPLI-
CATE ASSET.” Duplicate means that your
machine and another machine are sharing
the same asset number in the system. If
you get this message after programming a
BEII, you may have entered some informa-
tion incorrectly. If your information is cor-
rect, you may have to start looking for the
other machine.

If you have a “UID MISMATCH” displayed on

the NexGen, you more than likely have prob-
lem with the UID or the system. Resetting
the UID in the Machine Wizard program will
typically clear this up.

A message of “NOT IN USE” will almost al-

ways lead to a problem with the UID har-

the Ho-Chunk Nation Dejope Gam-

“During a recent expansion from

340 Class II bingo-style games to
more than 1,100 games, Dejope
selected Bally for approximately
600 games or nearly half of their
slot floor,” noted Alex Dungan, Vice
President, Class II & Central De-
termination Markets. “This marks
a significant increase of Bally slot
titles at this premier gaming facil-
ity.”

According to Dungan, a variety of

popular Bally reel-spinning and
video titles on both the new ALPHA
Elite™ S9E and wide-screen
CineVision™ cabinets are now
available for play at the Dejope
Gaming facility. These include: Hee
Haw™, Lucky Wheel™, Blues
Brothers™, In The Money™, Penny
Frenzy™, Double Blazing 7s™,
Mystic Lamp™ and Fireball
Frenzy™.

Additionally, the Class II gaming

facility recently converted its en-
tire casino floor from a competing
back-end casino management ac-
counting system to the Bally One
System™.

“We are delighted that Dejope se-

lected the Bally One System as
their preferred casino management
application,” stated Dungan. “The
Bally One System is designed to
give Class II/Central Determina-

capability of integrating all of their

Why would there be a rub-

ber stopper inside of a handle

to absorb some of the shock

coming together, there is a
piece of rubber (replaceable)

this is to give the noise when
the handle is being pulled. In

think that it's pretty cool that
some of the new stepper slot

Bottom Heating for

PCB Rework
By Marv Cohen
The time is determined by the
efficiency of the heating device
and the thermal conduction of
heat to the solder joint. A sol-
dering iron is still the most effi-
cient device because the heat
makes direct contact with the
solder joint. An alternative
method is the use of hot air and

have gone through major
changes. Most new circuit
boards are multilayer PCBs with
an increased density of sur-
rounding components near the
SMDs (surface mount devices).
When soldering components in
these dense areas, there is a
heat sink effect that draws the
required heat away from the
solder pads. The incorrect way
of overcoming this problem is by
increasing the applied solder
iron temperature to a point
where there is an even greater
increase in potential for dam-
age to the PCB board and com-
ponents. When soldering in
these dense areas, bottom side
preheat has many advantages
that will overcome this problem.

Soldering Iron Alternative

There is an alternative choice for

solder/desolder and general re-
work other than the traditional
solder iron. When applying heat
to a solder joint, a certain
amount of time is required to
transfer the applied heat to the
thermal load (the solder joint).

USING CHIP QUIK® WITH

PREHEAT FOR SAFE SMD RE-
MOVAL

Due to the low melting tempera-

ture of Chip Quik® removal al-
loy (136°F.) an SMD can be re-
moved using bottom heat only.
With the PCB bottom heated to
a safe bottom temperature of
300° F, apply flux to all leads of
the SMD. Apply Chip Quik low

USING A HOT AIR PENCIL AND
BOTTOM HEAT

Apply bottom heat and wait

until solder paste starts to acti-
vate. This will be visible when
the flux in the solder paste
starts to smoke. Now set the air
pencil for low air velocity and a
temperature of 500°F. Using the
solder pencil, slowly move from
pin to pin and apply heat. Watch
each pin/pad solder joint as it
is formed and then move on to
the next. If a solder bridge is
formed, apply more paste flux
and heat again. If this does not
work, use solder braid while
heating with the hot air pencil.
Clean all connections with an
acid brush and flux cleaner.
Check with magnification for

Subscriptions & Back Issues
Why back issues of Slot Tech Magazine are
important to own . . .

S lot Tech Magazine is strictly technical. As such, the

magazine's contents are not time critical. The repair
information and technical data contained in past issues is just
as valid today as it was the day it was published.

Additionally, current and future articles more-or-less assume

that readers are already familiar with what has been covered in
past issues. This editorial policy assures that Slot Tech Magazine's
contributing writers are not limited to "writing down" to the level of a novice
technician but are free to continue to produce the most comprehensive technical articles
in the gaming industry.
