Note: Always power down machine prior to Installation.
The cashbox does not lock to the chassis. When you remove the unit from the container or when the unit is not installed in the machine, you must
never carry the note acceptor by the handle of the cashbox. The cashbox may release causing the rest of the unit to fall and damage the
chassis.
Installing the Chassis
• Most models have a configuration-specific harness installed
on the back of the chassis (see Interface Manual p/n
252058039 for more details). Connect the harness from the
chassis to the host machine. Always dress all wires to avoid
interference with any equipment operation.
Note: If you have a custom configuration, you may need to contact our technical support group for assistance.
• Once the connections are made, you will need to line up the locating holes on the bottom of
the chassis with the machine’s locating pins. Line up the mounting screw holes and insert M4
screws through several of the 10 mounting holes. There are three on each side of the chassis and
four located on the back. Leave screws slightly loose until the entry guide is mounted and aligned
with the machine door closed. Screws must not exceed a 6mm depth through the mounting plate,
otherwise they may interfere with the removable cashbox.
Earth Grounding Considerations:
Use star washers when mounting the chassis via the back or side mounting options. If the side
mounting option is selected, use the lower mounting holes with an M4 screw to ensure a bonded
connection to the host machine.

Inserting and Removing the Acceptor Module
• Insert the Acceptor Module so that the release lever locks into place. The acceptor should be
firmly seated to ensure proper engagement of the
locking feature.
• To remove the unit, pull upwards on the release lever
located on the front of the Acceptor Module and pull
away from the chassis.

Installing an Entry Guide
• To install an entry guide, just slide it onto the acceptor module until it locks into place.
No screws are required. If the entry guide has lights, you will have to first connect the harness
from the entry guide to the eight pin connector located on the left hand side of the face of the
acceptor module.
• Make sure that the entry guide is aligned so the machine door closes properly.

Installing the Cashbox
• With the chassis mounted securely to the machine, you may now insert the cashbox into the
chassis. The cashbox has slots on both sides that will guide it into the chassis. When you insert
the cashbox, you will feel some resistance from the two springs inside the chassis. Make sure to
insert the cashbox all the way in so that the rear of the cashbox is flush against the chassis wall.
Removing the Cashbox
• When the note acceptor is installed in a machine, you just need to grab the yellow strap on the
cashbox and pull firmly to release it. The
cashbox does not lock on to the chassis.
• To remove the cashbox when the unit is not
installed, grab on to the yellow handle and
place your thumb on the chassis where indi-
cated in this diagram. Placing your thumb at
this location will give you sufficient leverage to
remove the cashbox.

The cashbox may be fitted with either one or two security locks. The product is designed to
accept locks from a range of manufacturers including: -
Medeco
Kaba
Abloy
VSR
Miwa
Duo
ILCO
Standard 5/8" and 1-1/8" formats are supported. There is a significant variety of lock designs,
and spacer washers may be required for some lock types. Locking hasps are shipped with every
cashbox. Contact MEI for cashbox lock specifications.
Locks vary greatly in price, security, keying policies, etc. The customer is responsible for selecting
a lock with performance that is fit for the intended purpose. MEI does not test or endorse any
specific brand of lock for security characteristics. For applications requiring NO locks, a non-
secure “slam” latch is available: MEI Part Number 252260001P1/P12 NLC CASHBOX
LATCH.
When only one lock is used, the remaining blank hole does not give access to the contents of the
cashbox. However, some jurisdictions may require a blanking plug. Contact MEI for assistance in
obtaining a suitable plug.
When two locks are installed, they must rotate in opposite directions. See the figure below.

UPDATING SOFTWARE
There are two ways of updating the software of a Cashflow SC83 note acceptor.*
1) Via a hand held device called the Cashflow
Programming Module (CPM).
2) By replacing the programmed PROM (Chip Change).*
Cashflow Programming Module
Connecting the CPM to the CASHFLOW SC83
1. Locate the two USB ports located on the top of the Cashflow
Programming Module (See fig. 1 below).
2. Plug the type A end of your USB harness to the USB type A
port of the CPM. Plug the type B end of the same USB harness
into the USB type B port of the Cashflow SC83. (see fig.2).
fig.2
download button
fig.1 (CPM)
Type A USB port Type B USB port
*Note: Once a PROM (chip) is installed, the note acceptor can no longer be programmed via the programming
module (CPM). Installation of a PROM will disable the ability of the programing module (CPM) to communicate with
the note acceptor. Future software changes can only be made by replacing the PROM (chip change).

MEI CASHFLOW SC83 Page-15
www.meigroup.com Part # 252055088 G3
UPDATING SOFTWARE
CPM Downloading Procedure
1. After connecting the CPM to the Cashflow SC83 via the USB interface (refer to previous page
illustration), you are now ready to start the download procedure.
2. Press the square download button located on the front of the CPM. (see fig.2 on previous
page)
3. When downloading, the CPM will have a solid green and a flashing red LED, indicating the
CPM is busy. Once the dowload is complete, the LED on the CPM will change to solid green and
a solid red, indicating a successful download. The note acceptor will perform a run and stack and
the the LEDs on the CPM will turn off.
4. Disconnect the USB harness from the Cashflow SC83 once the LEDs on the CPM are off.
5. Once dowload is complete, the Cashflow SC83’s diagnostic LEDs will flash five times green
continuously until communication between the note acceptor and the machine is re-established.
Diagnostic Codes For The CPM
Led Codes: solid green = CPM on
solid green + flashing red = CPM busy
solid green + solid red = upgrade complete
Error Codes: flashing green = battery low
alternating flashing green and red = wrong product connected
solid green + flashing red 1 time = notes reader error
solid green + flashing red 2 times = CPM error
solid green + flashing red 3 times = program error

UPDATING SOFTWARE
Replacing the programmed PROM (Chip Change)
This is not necessary for all applications, but only those that occur in jurisdictions requiring
PROM to be installed.
Note: As soon as even one PROM has been installed into an acceptor module, the acceptor
module will not be able to be re-programmed with a CPM. To re-program an acceptor module
that has had a PROM installed, you MUST change or insert a new PROM (perform a chip
change). When power is re-applied, the Acceptor module will be re-programmed from the
PROM.
1. Remove the acceptor module from the chassis. (Instructions on how to remove it are on page
10).
2. Open the acceptor module by placing the palm of your hand on the front of the module and
placing your fingers around the top of the yellow cover as shown in the diagram below. Pull the
cover toward your hand and then lift up, opening the module head fully.
3. Remove the yellow cover from the acceptor module by turning the acceptor module so that the
top of the cover is facing you. Wedge the tips of your fingers underneath the left and right front
top corners of the yellow cover. Lift the cover’s corners out and then back toward you to release
the cover. The cover will be released once the cover has cleared the black ramps as shown in the
diagram below.
4. Once the yellow cover is released in the front, slide it back and remove it.

Non Committed Contacts
Depending on the desired interface, the SC83XX may be supplied with one or two sets of non
committed contact leads for OEM use. The contacts are rated at 125VAC, 5AMPs Maximum.
Wire connections are as follows:
Maintenance
Periodic maintenance can improve the performance and extend the working life of a note
acceptor. Additional attention may be required if the note acceptor becomes inoperable due to a
jammed object or acceptance rates fall below normal.
Cleaning the Acceptor Module
Note: You must remove the acceptor module from the chassis to open the front sensor area. Forcing the note path open without removing the
acceptor module from the chassis will damage the unit. Remember to turn off the machine (as per machine manufacturer) when performing any
cleaning.
• Remove the acceptor module from the chassis. (Instructions on how to
remove it are on page 10).
• Open the acceptor module by placing the palm of your hand on the front of
the module and placing your fingers around the top of the yellow cover as
shown in the diagram to the right. Pull the cover toward your hand and then
lift up, opening the module head fully.
• Clear the note path area of any foreign objects.
• Wipe the note path and sensor areas as needed with a soft damp cloth. For
stubborn dirt, a small amount of mild non-abrasive soap may be added to the
water before dampening the cloth. Make sure no streaks or residual soap remain on the note path.
Note: SC83 does not require the use of a cleaning card. Never use a petroleum-based product to clean this device! Petroleum based products
will damage the note path. Mild non-abrasive soap is preferred over alcohol.
Calibration
The SC83 series note acceptor was designed not to require calibration. Thus, the unit has no
switch settings or calibration mode that allows a user to perform a calibration. Calibration may
only be performed by MEI trained technicians.
