PRODUCT IDENTIFICATION
Mars Electronics International (MEI) has manufactured coin mechanisms compatible with
gaming and amusment machines for a number of years. Over this time the functionality of
the range has been enhanced to match your needs and still maintain mechanical
compatibility. The product detailed in this book is the CashFlow series. Use the following
pages to check you have the right product for your application.
CashFlow® 126 and CashFlow® 129 selectors User Guide
The entry bezel and the Y-chute options can be used with either the CashFlow® 126
system or CashFlow® 129 system. The CashFlow® 126 can be supplied for fitting into a
short channel, so long as the machine has suitable mounting points for the bezel and
Y-chute.
The Y-chute is available in two versions, the one shown above which includes electronics
with back illumination of the dual coin/token bezel, and a version which has no
electronics. This version is suitable for coin only applications.
In a coin only application the interface loom from the machine goes directly to the
validator. The use of the dual coin/token application, however, requires a different loom,
which connects as shown above.
CashFlow® 126 and CashFlow® 129 selectors User Guide
The electrical connections and interfaces to each variant of CashFlow® 126 and
CashFlow® 129 are identical, and are found in the same locations.
(A) Machine Interface - This provides power to the validator and carries the coin inhibit
signals from the machine and coin outputs to the machine.
(B) Routing Plug - This comprises a series of links fitted to a route plug housing and is
used to set up the primary coin exits and any specific overflow exits.
(C) Separator Connector - The separator interface connection must be made before
physically attaching the validator and separator together. The separator will direct
accepted coins/tokens to defined exits.
(D) Route Inhibits -This connector is used to signal that a particular exit has reached
“full” status. Subsequent coins will be diverted to their defined overflow exits.

INSTALLATION
Installing or removing the CashFlow®® product from your machine can be done by
following these simple instructions.
+ When installing the CashFlow®® 126 Front Entry product it will be fitted to an MEI Front Plate and
the following instructions will always apply.
+ The mounting channel for the CashFlow®® 126 top entry product is supplied by the machine
manufacturer, and therefore some variations may exist from machine to machine, however in
principle these instructions still apply.
CF126 Front Entry Installation
q Connect the separator loom to the connector at the base of the validator and locate
the rectangular boss on the top of the separator into the base of the validator.
q Firmly screw the separator fixing lugs onto the rear of the validator.
q Having ensured that the front plate has a firm location onto the front of the
machine, insert the side of the validator onto the two round bosses at the rear of
the front plate and push firmly together until the two retaining clips are fully
engaged.
CashFlow® 126 and CashFlow® 129 selectors User Guide
+ When mounted into a short channel the product must be fully assembled and ready for use,
with only the machine interface loom to be connected.
q The mounting points indicated must be firmly seated into the channel and a
gap of between 2-3 mm left between the reject lever and the reject arm from
the machine. This small gap will ensure that the validator lid is able to fully
close when the reject button on the machine has been pressed and released.
The two Y-chutes already referred to can both be used with the short channel
version, but care must be taken to ensure that the gap mentioned above is
maintained between the Y-chute reject arm link and the reject lever of the coin
mechanism.
CashFlow® 126 and CashFlow® 129 selectors User Guide
CashFlow® 129 System Installation
The system consists of a channel, Y-chute, CashFlow® 129 validator, 8-way separator,
manifold and tube collar plate.
This is supplied as a complete system, but should you need to replace any part of it do so
only in a set sequence, starting from near the top.
+ The Y-chute can, of course, be removed first, but it is not necessary to do so just to access the
other modules.
Removal of Validator and Separator
q Ensure that power is turned off, not only to the validator, but also to the Y-chute if
live.
q Dis-connect machine interface loom, and the route inhibit connector.
q Dis-engage the release catch and lift the validator and separator upwards out of
the mounting points. Pull the validator and separator forwards clear of channel.
CashFlow® 126 and CashFlow® 129 selectors User Guide
ACCEPTANCE AND ROUTING
When the product is successfully mounted you will need to confirm that it is set up
correctly to accept good coins/tokens and direct them to where you want them to go.
First things first
q Press and release the reject button on the machine. Confirm that the lid on the
front of the validator closes fully when the reject button is released. If it does not
close fully the validator cannot function properly.
q Test that power is on by checking that the green LED on the front of the validator is
illuminated, it will flash off once when the reject lever is pressed.
Testing for Acceptance
q Insert into the machine a selection of all the coins/tokens shown on the validator
label. Acceptance of each one will be indicated by the LED flashing off once, and if
the coin/token is outside of the programmed window it will flash off twice. If the
LED flashes three time this indicates that the coin/token has been rejected by the
validator 4th sensor. Should the LED flash off four times this indicates either a
hardware or software inhibit is being applied.
Coin Routing
q Confirm that all coins and tokens are being routed to the required exits. If they are
not refer to the Trouble Shooting section. Settings may have been made on the
machine for hopper or tube limit switches, and these must be taken into account.
q If further help is required then consult the Operators Handbook for the product or
contact either your distributor or local MEI office.

PRODUCT FEATURES
The CashFlow® 126 and CashFlow® 129 products have the flexibility to change certain
settings such as varying the coin-set that it handles, or new routing for some of the
coins/tokens.
These changes can be carried out using the rotary data switch and the configuration
switch which are fitted uniquely to the CashFlow® 126 and CashFlow® 129 products. The
following pages show how, with the use of these switches, coins/tokens can be inhibited
or enabled, either a new individual token or a group of tokens selected and the machine
output mode changed.
In addition to these two switches there is a green diagnostic LED which signifies if any
changes you make have been successfully actioned or not.
Changes can also be made to the coin routing with the use of
a routing plug.
The routing plug is available in two forms, either ready-made
for specific applications, or do-it-yourself kits, consisting of
loose plugs and either wire links with crimps at each end or
links incorporating a sleeved IN4148 diode with crimps at each end. The diode version is
required to give protection from shorting where two separate coins are required to got to
the same exit. An illustration of how these can be assembled is shown on the next page.
Both versions are available from your distributor, who can assist you with assembly
details.
A summary follows of the way in which you can use the above features. For greater detail
of how to use all of these features you are advised to contact either your distributor or MEI
office for technical assistance.

CONFIGURATION
Validator Interface Connector
The interface to the validator from the machine is exactly the same as those which apply
to the MS/ME series validators, with the exception of pin 8 of the 17-way connector
Connector 1 can accept either 15 pin or 17 pin interface connectors.

Assembling a 22-Way Routing Plug
While the links are readily inserted into the routing plug by hand without specialist tools,
care is needed to ensure that they are fitted the correct way round, particularly with the
doide version, so that the barb in the pin engages with the recess in the plug. Having
inserted a link give it a gentle tug to ensure that it has engaged with the recess.
CashFlow® 126 and CashFlow® 129 selectors User Guide
Route Inhibit Connector
The function of the route Inhibit Connector is to signal when specific exits, external to the
product, are in a “Full” condition. Signals from the machine ensure that, while the “Full”
condition continues, further coins/tokens directed to that exit will be re-routed to an
alternative exit. The instruction as to which alternative exits can be used will normally
come from the routing plug.
+ In order to inhibit a particular route, 0V must be applied to its respective pin.
+ An alternative route must always be of a lower priority

Using the Rotary Data Switch and Configuration
Switches
Rotary Data Switch
The rotary data switch is used in conjunction with the
configuration switches. By pointing the arrow in the middle of
the switch, using a fine screwdriver, data can be entered into
the product. In Normal Operation mode the position of the arrow
is not critical to correct operation.
Configuration Teach Switches
These switches can be set to a series of positions which enable the product configuration
to be changed.
When teach modes are to be entered first SWITCH POWER OFF to
the unit, or an un-intended action could be set.
The example given here, with both the rotary data switch and the
configuration switch settings, is to enable channel 3 in the coin set.
+ Wherever in the examples that follow the switch is shown as hatched grey (usually switch 1) it
indicates that it does not matter if the switch is in the ON or OFF position. Switch 1 only features
in the settings for Alarm Enable when it must be in the ON position. When it is in the OFF
position the Alarm function is NOT active.
q After making any changes the
configuration switches 2, 3, and 4
MUST always return to either of the
Normal Operation positions shown
here.
Diagnostic LED
q The LED will illuminate to indicate that the product is
powered up, and in addition will give various sequences of
flashes to confirm the acceptance or rejection status of
coins/tokens.
+ Flash Sequence:Constantly ON Validator Power On
1 FlashCoin accepted / Reject lever pressed

MAINTENANCE
+ The practical maintenance that can be carried out is limited to cleaning the areas of the
validator that the coins travel through, and the replacement of the coin entry liner if it becomes
worn. All other servicing is carried out through your distributor.
The cleaning should be carried out on a regular basis of at least once a month, but, if you
have to visit the validator outside of that routine, it is worth while doing it then as well.
The shaded areas shown below, plus the back of the reject cover, are those to be cared
for.
The coin entry liner is accessed by unscrewing the coin entry moulding at the top of the
validator. The coin entry liner can then be eased off with the aid of a fine screwdriver, and
a replacement slid into place.
q Cleaning and maintenance must only be carried out by suitably trained personnel.
q Cleaning must only be carried out after power has been removed from the product.
q Never use a cleaner containing solvents, scrapers or abrasive materials.
q Never apply water or cleansers directly onto the product. Always apply them to a
clean cloth first, and not too liberally, so that the cloth used is only moist.
