Serial Number Explanation
Example:
NOTE:
From week 09 2009 the number representing the Manufacture Location changed from an 8 to a 9.
This will allow the warranty serial number to continue into 2010 when the year code of 0 would be
duplicated with units already manufactured in 2000.
i.e. 0988 = manufactured in Week 9 2008
0999 = manufactured in Week 9 2009
0908 = manufactured in Week 9 2000
0909 = manufactured in Week 9 2010

INSTALLATION
Unpacking the Note Acceptor
Unpack the note acceptor and immediately inspect it for damage. If the unit is damaged, return it to its
original carton along with packing materials.
Notify the delivering carrier of damages and request immediate inspection. Send a letter of
intent to file a claim to the delivering carrier within 72 hours from the time of delivery. Send a
copy of the letter to the shipper.
Only the consignee (the person or company receiving the note acceptor) can file a claim against the
carrier for concealed damages.
Retain the original carton and packing materials for future use in shipping or transporting the
note acceptor.
Mounting the Note Acceptor
The Cashflow©2612 has been designed for ease of mounting onto existing studs provided
by Original Equipment Manufacturers (OEMs). Some machines may require brackets or
faceplates to mount the unit. Refer to your machine operation manual or contact your
distributor/OEM for more model-specific mounting information.
The Cashflow©2612 has a tie-wrap included with each unit to secure its interface harness to
the mounting area of the machine. Use the tie-wrap for every installation.
1. Disconnect all power to the machine.
2. Connect the interface harnesses from the
machine to the unit.
3. Wrap the tie-wrap around the interface harness.
5. Secure the unit to the mounting studs with the appropriate hardware.

Changer Configuration
The majority of Note Acceptors are fitted to a Changers MDB Peripheral loom. It is advisable that
some options within the changer are adjusted when a Note Acceptor is fitted.
MDB Peripheral Loom
Highest Banknote Value
In the Service Mode Menu there is an option to set the highest value of Banknote. This is under
Banknote Configuration. It is normally set at €20.
Software
Since MEI software release V1.18 the behaviour of a Note Acceptor connected to the MDB
Peripheral loom is different. All the notes inserted will be held in escrow, which means not stacked
until the user makes a selection on the vending machine. Then the note will be stacked in the
magazine and the user will get the product and the change (in coins).
If the user inserts a note and presses the reject lever to get change, then the note will be returned.
This is to prevent users emptying the changer’s tubes without buying anything.
This option is only configurable with the STS tool.
Payout
If you are going to use a Note Acceptor it is recommended you change the payout of the Changer
adding one tube of €1 or €2 depending on the needs of the site. CF7000 has a wide range of pre-
programmed cassettes. Please contact your MEI technical support or local service center for further
information on this.
Testing
•Apply power to the machine.
•Check the Status LED for the "Steady ON" condition. If another condition exists, refer to the
Maintenance section for troubleshooting details.
•Insert a note to check acceptance. If enabled, the note should be accepted.
•Make a vend to ensure the proper credit is received and proper change is paid out for the note.
Warranty
All Cashflow©2612 Note Acceptors come with a Two Year Manufacturer’s Warranty. Once the unit
has been inspected, record the model and serial number from the label on the side of the note
acceptor. Refer to these numbers when you contact an MEI Approved Service Center for service or
information. The manufacturer’s warranty is based upon the date of manufacture. Parts and labour
are included in Warranty repairs.
The first four digits of the serial number contain the manufacturing date code (see Serial Number
Configuration section). This code indicates the beginning of the warranty period.

CONFIGURATION
The Cashlow©2612 can be manually configured using a bank of eight option switches.
The Cashflow©2612 can also be configured using a configuration coupon.
Factory Configuration
The Cashflow©2612 Note Acceptor is factory configured with all switches in the OFF position.
The following configuration is programmed:
•Maximum directions for note acceptance (four-way)
•High acceptance
•€5; €10 Euro note enabled
•1 pulse per Euro
•MDB Interface
The unit will default to these selections whenever all option switches are OFF. Placing any
switch ON will override the factory settings and the note acceptor will operate according to the
switch settings you choose.
If the Cashflow©2612 is reprogrammed using a coupon with a different configuration, the new
configuration will be the default. If any option switch is turned ON, the option switch settings
will override the coupon setting. The coupon configuration will remain in memory.

Cashflow

©MEI 2009 Page 18 G1
Switch Settings
The Cashflow©2612 allows configuration of interface options through option switch selection.
The option switches are located on the right-hand side of the note acceptor. The following pages
described how the option switches work for specific country variants.
