Vending Notes: DBAs

Just as promised last rronth, I am going to
do my best to inform you of new
developnents and service updates in the
Vending Industry. Vending has come a long
way and is presently utilizing many
high-tech items. Arrong the high-tech items
is the use of Ibllar Bill Acceptors
(OBAs).
All the manufacturers have been making
provisions for installing OBAs in their
vending machines. There has been a little
confusion, however, aoout which changers
to use in conjunction with the various
OBAs -not to mention correct harnessing.
The three major manufacturers of OBAs are
Ardac, Mars and Maka. The Ardac and Mars
units are American made, while the Maka is
an up-and-coming Japanese model. At this
time, Mars has halted production on their
OBA to correct a minor problem. Ardac and
Maka are still available.
Because of the situation with Mars,
manufacturers are looking at options for
the interim period. Vendo/USI will use the
Maka system for their factory
installations. The installation will
require three rrounting brackets. The part
nlllllbers are: 620699, 620715 and 620700. A
bezel plate, nlllllber 210244, will also be
required. This OBA will be used with
either a Mars MC-5000 or Coinco C-300-F
changer. Harnesses are included with the

there is a remote possibility that credits
can sometimes be lost, even trough the MBA
system has properly recognized the
inserted bill and sent out the proper
nlllllber of credit pulses.
There are two possible solutions for this
problem and ooth involve the timing of the
credit pulse train from the MBA system. As
Ardac ships the MBA system fran the
factory, it uses a fast credit pulse train
of 50 ms on, 75 ms off, 50 ms on, 75 ms
off ... etc. If the j ~ r in pin 19 of the
21 pin plug used on the MBA control is
removed, the credit pulse train is slowed
down to 75 ms on, 300 ms off, 75 ms on,
300 ms off ... etc.
Ardac has developed a special E-PRCM as an
alternative. This will change the credit
pulse train to provide a long waiting
period after the first credit pulse is
sent for games that use the first credit
pulse to reset fran attract mode to play
mode.
This Attract-to--Play Delay E-PR0-1, part#
X-13200, may be ordered from Ardac for a
nominal charge of $25.00. Additional
questions srould be directed to Stan
G:>ssard. Stan is Ardac's new National
Service Manager and can be reached at

I don't know what route the other

look into the subject.
Rock-Ola has a new electronic cold can

uses the same control board as the Vendo

manufactured by Mars for the Vending
