Validator Update Instructions for Rowe BC3500 $1-$20
Kit Overview
The purpose of the kit is to replace the Rowe BA50 transport and stacker with a 120-volt
Mars validator with a compact mask. The kit and these instructions pertain to a Rowe
BC3500; this is a front-loading changer with three hoppers. There are two variations of the kit;
one will process $1-$5 and the second $1-$20. This kit is designed for dollar bill changers
that are not used to make change for a coin. If you are accepting coins please, contact us
for a coin interface kit. The kit will work with all variations of the Rowe BILL CHANGER
CONTROL COMPUTER boards.
The installation information is intended for experienced personnel familiar with the operation
of these components. All of the installation procedures must be reviewed and understood
prior to installing the kit. The installation instructions are based upon a dollar bill changer
that has not been modified from the original factory configuration. If the machine has been
altered in any way, restore the machine to the original factory configuration prior to
beginning the conversion.

Pliers
Installation Instructions
1. Unplug the power cord from the wall and open the door of the changer.
2. Remove the BA50 bill transport by unplugging the harness at the 15-position harness
connector (3 x 5). A 12-inch harness will still be connected to the side of the BA50
transport
3. Connect the jumper supplied with the kit to the now open 15-position connector of the
machines wiring harness.
4. Remove the bill box from the stacker assembly.
5. Remove the stacker assembly by unscrewing the two ¼” screws at the top of the
assembly. It may be necessary to hold the nuts under the assembly with a pair of
pliers. [For changers with a dual stacker remove the two ¼” screws that secure the
stacker assembly base to the bill box bracket. The bill box bracket can remain in the
changer] Disconnect the harness from the upper rear right hand side. Slide the

stacker assembly forward out of the changer. Replace the upper two screws and nuts.
The original stacker harness will not be connected to any component.
6. Set the dip switches on the 120 volt Mars validator per the label on the kit Module.
7. Unplug the 9 position harness at the Coin Acceptor Assembly.
8. Insert the 9 position harness from the new Module into the open connector. This kit is
not designed for use in a changer that accepts coins. The 9 position female connector
on the Coin Acceptor Assembly will remain open. If you need to accept coins, please
contact us for a coin interface kit.
9. Remove the three hoppers from the Coin Dispenser Assembly 6-50275-10.
10.Unbolt the Coin Dispenser Assembly by removing both 3/8” bolts.
11.Pivot the assembly forward, it does not need to be removed. [If you are having trouble
connecting the new harness you may wish to disconnect the harness from the Coin
Dispenser Assemble so it can be removed.]
12. Feed the harness with the two 3 position connectors from the Module through the barrier
wall toward the left wall of the changer. There is a large hole with an insulating ring
toward the upper rear of the wall.
13.Unplug the main power harness from the connector at the far left of the Power Control
Center Assembly (65042606).
14.Plug the 3 position male plug from the Module into the now open connector on the
Power Control Center Assembly. Plug the machine harness into the female side of the
harness.
15.Set the Coin Dispenser Assembly back into place and secure using both bolts. If the
harness was disconnected be sure to reconnect the harness.
16.Replace the 3 hoppers.
17.Mount the validator onto the metal validator slide plate; the four 11-32 keps nuts are
supplied with the validator. A 12 inch factory harness may be connected to the validator
when it is removed from the box. Unplug this harness, as it is not used with the kit. If
the validator’s dip switches have not been set, set them now. The label on the Module
lists the various settings.
18.Slide the validator plate assembly down the tracks that originally secured the BA50
transport. Attach the harness from the Module with the long black connector to the
validator. Note the position of the two “keyed pins” when attaching the connector.
19.Secure the Module in a safe location. The recommended location is in the alarm canister
clips located directly behind the coin acceptor assembly.
20.Remove either of the 2 wires from the coin return switch; red or black. Wrap the
terminal in electrical tape.
21.Plug the changer back into the wall and turn the power switch to the ON position.
22. At this point the BILL CHANGER CONTROL COMPUTER is reprogrammed.
The 2 most popularly used programs are described below. The programming for the MC
mode assumes 4 quarters will be dispensed for each dollar value inserted. If you are
dispensing dollar coins divide the number of coins to be dispensed by 4. The below
instructions can be used as a basis for substituting your own values if needed. The values
you are programming may seem odd, however the validator now controls the
denominations accepted. The MC mode is recommended if you are dispensing the same
value coin in all 3 hoppers. The operation of the MC Mode is described on page 2-11 in the
Rowe BC-3500 Bill & Coin Changer Field Service Manual and Parts Catalog; seventh edition.
It is also described on page 2-12 in the Rowe BC-1200/1400 Bill & Coin Changer Field
Service Manual and Parts Catalog; fifth edition.
