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 bill 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 cable installed
on the back of the chassis (see Interface Manual 002850103
for more details). Connect the cable from the chassis to the
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. Then line up the mounting screw holes and insert
M4 screws through as many 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 bezel 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.

Installing A Bill Entry Guide
•To install a bill entry guide, just slide it onto the Acceptor Module until it locks into place.
No screws are required. If the bill entry guide has lights, you will have to first connect the har-
ness from the bill entry guide to the eight pin connector located on the left hand side of the face
of the Acceptor Module.
•Make sure that the bill 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 bill 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 were indicated
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
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. Two 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.
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 SC66 bill acceptor.*
1) Via a hand held device called the cashflow Portable
Programming Module (PPM).
2) By replacing the programmed PROM (Chip Change).*
Portable Programming Module
CONNECTING THE PPM TO THE CASHFLOW SC66
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 cable to the USB type A port
of the PPM. Plug the type B end of the same USB cable into the
USB type B port of the Cashflow SC66. (see fig.2).

fig.1 (PPM)
Type A USB port Type B USB port
*Note: Once you install a PROM (chip), the bill acceptor can no longer be programmed by the Programming module
(PPM). Once a prom is installed, the bill acceptor disables the ability for the programing module (PPM) to
communicate with the bill acceptor. Future software changes will have to be made by replacing the PROM (chip
change) only.

UPDATING SOFTWARE
PPM DOWNLOADING PROCEDURE
1. After connecting the PPM to the Cashflow SC66 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 PPM. (see fig.2 on previous
page)
3. When downloading, the PPM will have a solid green and a flashing red LED, indicating the
PPM is busy. Once the dowload is complete, the LED on the PPM will change to solid green and
a solid red, indicating a successful download. The bill acceptor will perform a run and stack and
the the LEDs on the PPM will turn off.
4. Disconnect the USB harness from the Cashflow SC66 once the LEDs on the PPM are off.
5. Once dowload is complete, the Cashflow SC66’s diagnostic LEDs will flash five times green
continuously until communication between the bill acceptor and the machine is re-established.
Diagnostic Codes For The PPM
Led Codes: solid green = PPM on
solid green + flashing red = PPM 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 = bill reader error
solid green + flashing red 2 times = PPM error
solid green + flashing red 3 times = program error

UPDATING SOFTWARE
Replacing the programmed PROM (Chip Change)
Note: Once you remove the programmed PROM(perform a chip change),the bill acceptor can no
longer be programmed by the Programming module (PPM). Once a PROM is inserted or
removed, the bill acceptor disables the ability for the programing module (PPM) to communicate
with the bill acceptor. Future software changes can only be made by replacing the PROM
(chip change).
1. Remove the acceptor module from the chassis. (Instructions on
how to remove it are on page 8).
2. Open the acceptor module.
3. Release the yellow cover from the left and the right front corner
of the acceptor module. Lift the cover to release the
clip on both sides.
4. Once the yellow cover is released in the front, slide it back and remove it.
5. You may now remove the PROM using a PLC puller.

Periodic maintenance can improve the performance and extend the working life of a bill accep-
tor. Additional attention may be required if the bill 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 bill path open
without removing the Acceptor Module from the chassis will damage the connector board located at the rear of the
Acceptor Module. Remember to turn off the machine (as per machine manufacturer) when performing any cleaning.
•Release the Acceptor Module from its normal operating position.
•Open the Acceptor Module unit by pulling up on the yellow cap.
•Clear the bill path area of any foreign objects.
•Clean bill path and sensor areas as needed.
For stubborn dirt, a small amount of mild non-abrasive soap may be applied to a damp cloth.
Make sure no streaks or residual from the cleaning product remain on the bill path.
Note: SC66 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 bill path. Mild non-abrasive soap is prefered over alcohol.
Calibration
The SC66 series bill 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 one of our trained technicians.

Diagnostic Codes
The chart below indicates the 15 color-coded combinations of diagnostic LEDs on the acceptor
module. For each color, there is a solid indicator and four flashing combinations. If multiple
failure conditions occur, the most severe condition will be displayed.
Red conditions - Hard Fault. One of the bill acceptor components needs to be replaced.
Yellow condtions - Soft Fault The operator can correct the issue at the machine.
Green conditions - No Fault No problem with the bill acceptor.
Note: By opening the machine door, you will disable the primary interface. The 10-second delay allows you to see
a normal condition on the unit prior to the MMI display update.
