MAYTAG CIRCUIT BOARD

The Maytag Circuit Board Interface

The Maytag CompuTrac Circuit Board was designed to work with advanced payment type of

systems along with coin drops and coin slides. By creating this interface, Maytag has provided a

way to connect readers without the need to modify existing machine wiring. The interface Maytag

has provided on their CompuTrac Circuit Board allows for two forms of communication with

external devices. The first being through Enables and Availables and the second provided through a

serial connection.

Connection through Enables and Availables:

When connecting card reader equipment using the Enables and Availables the reader monitors if the

machine is in use through a set of contacts providing a short circuit on the Avail1 and Avail2

connections. The reader starts the machine though the Enable 1 and Enable 2 circuit by providing a

5 volt 30 milli second pulse to the Enable 1 circuit in reference to the Enable 2 ground circuit. The

Maytag board can be configured to work off of one pulse or multiple pulses. Depending on if the

machine is going to be connected with card and coin support at the same time will determine the

number of pulses the reader needs to be setup with. If the machine is programmed to take three

quarters to start, then the reader will need to provide 3 pulses to start the machine. If the machine is

not going to be connected to coin then it is suggested to program the Maytag board so that 1 pulse

equals to the total vend price, also setting up the card reader with one pulse.

Connection through a PR or PR/PD interface:

When connecting a PR or PR/PD reader to a Maytag Circuit Board, upon power up the board

immediately locks itself in Enhanced Debit mode, locking out all other forms of card reader

communication. This board is now dedicated as a PR or PR/PD reader ready circuit board and

cannot communicate with coin slides, drops or retro-fit readers.

PR & PR/PD READERS DESCRIPTION Smart Vend PR & PR/PD Readers The Smart Vend PR Reader is a smart card reader that has been developed to work directly with Maytag PR machines. PR readers are the substitute for coin drops and/or coin slides at the washer or dryer. The PR reader communicates serially with the Maytag Circuit Board making it difficult to cheat or bypass the reader due to the complex communication which takes place between the reader and Maytag Board.

READER PROGRAMMING Keys to Successful Programming Programming a PR, PR/PD or SLIM Retro reader successfully relies on having a known good, complete set of setup cards. Never mix cards from one location with another. Also keep the setup cards together so if ever needed, all of the cards will be ready to use. When removing keys from a PR & PR/PD reader, four dashes across the Maytag Circuit Board Display indicate the keys have been removed from the reader.

THE PROGRAMMING CARDS Key Card: Card # 1 The Key Card is always the first card inserted into the reader, PR, PR/PD and SLIM Retro. This card loads the keys “secret passwords” into the reader so that competitors’ equipment won’t interfere with another. The keys can also be removed from a reader by reinserting the Key Card back into a reader that already has the keys installed. In order to remove the keys from a reader the Key Card must contain the exact same keys that were previously loaded into the reader.

PR & PR/PD READER SETUP PROCEDURE Smart Vend PR & PR/PD Readers The PR & PR/PD Readers can be setup with the same setup card sets. Only a retro-fit reader will need a special set of setup cards to be setup. The key to successfully setting up a PR or PR/PD Reader is to insert each card #1 - #4 in sequential order waiting for each card for the “Pull Card” message on the Maytag Board Display.

SLIM RETRO READER SETUP PROCEDURE Smart Vend SLIM Retro Readers The SLIM Retro-fit reader needs a special set of setup cards to be setup. Following is a list of procedures to setup a SLIM Retro-Reader. 1. Install the SLIM Retro reader into the machine 2. Plug in the machine 3. Insert the System Key Card and wait until it indicates that it is complete 4. Insert a Site Code card and wait until it indicates that it is complete. 5.

PR & PR/PD READER WIRING Wiring the PR and PR/PD reader to a Maytag machine consists of connecting one wiring harness from the Maytag Circuit Board to the card reader. There are two different connectors that are used on PR, PR/PD reader harnesses. One end has a 6-Pin connector that connects to the Maytag Circuit Board and the other end has a 8-Pin connector that connects to the reader.

BASIC TROUBLESHOOTING PR & PR/PD Reader 1. Check for a Fault Code Displayed on the Maytag Board 2. Test with a User Card 3. Attempt to Reprogram the Reader • When reprogramming the reader, the keys are toggled on and off each time the Key Card is inserted 4. Change the Reader with a Brand New Reader 5. If needed use a machine next to the bad machine to help diagnose the problem, follow where the problem goes when swapping components SLIM Retro Reader 1.
