Card Insertions not recognized by the card reader

All card insertions should be reflected on the FEC display in some manner. For example, if a valid cash card is inserted into the reader, the FEC display should show the balance on the card.

A simple test is to insert any non-smart card (credit card, etc.) into the reader. The display should display an EC:20. This indicates that the reader recognizes a card has been inserted, but it cannot read it. Also this verifies that the reader is communicating successfully with the Front-End Control (FEC).

If the card insertions are not reflected on the FEC display, one of the following conditions has occurred:

•Card reader harness not hooked up or wired incorrectly.

•Card reader is not recognizing card insertions.

•Card reader is not capable of communicating with the FEC.

•If a network board is present, it has malfunctioned.

•FEC has malfunctioned, and is not supplying power to the reader.

•FEC has malfunctioned, and is not capable of communicating with the reader.

If the FEC senses that a card reader is present and the reader fails to communicate with the FEC, it will display an EC:19 error after 2-1/2 minutes. However, if the FEC never recognized that the reader was present at power-up, there will be no error displayed to indicate that there is no communication with the reader.

EC:19

NOTE: An EC:19 error indicates that the FEC recognizes that there is a Card Reader present, but it has not received a communication from it in the last 2-1/2 minutes.

Network Board Present - If a Network Board (NWB) is present, it is possible that it has malfunctioned. A bad NWB can prevent the reader from communicating with the FEC, resulting in an EC:19. Before powering down the unit, examine the LED on the NWB. If the LED is NOT flashing one second on/one second off, it is not functioning correctly. It will need to be either reset ( by powering down then up again) or replaced.

Troubleshooting

If a Network Board is present, it is helpful to eliminate it, if possible, from the circuit temporarily for troubleshooting purposes. Unplug the harness from the NWB to the Card Reader, and also unplug the harness from the NWB to the FEC. Next, connect the harness which is used to connect a Card Reader directly to the FEC.

NOTE: This harness is not included in machines containing a NWB. The individual performing the service to the machine will have to have this harness.

If the EC:19 disappears once the NWB has been removed (allow approximately 120 seconds), the NWB may need to be replaced, since the reader was able to communicate with a direct link to the FEC. Ensure that the reader is now operating properly by inserting several cards in the reader, and looking for the appropriate response on the FEC display.

Once the NWB is removed from the circuit, continue to "NWB Not Present" below.

Network Board Not Present - Begin by checking the voltage to the card reader. The following measurements should be taken at the 14-pin header on the card reader. There should be between 24 and 38 volts DC across pins 3 and 12. This voltage must be present, or the reader will not operate. Also, there should be 5 volts DC across pins 10 and 12. This voltage must be present, or the FEC will not recognize that the card reader is present.

If the voltages mentioned above are found to be present at the reader’s 14-pin header and the reader is not functioning correctly, the harness may be bad, the FEC may be bad, or the card reader may be bad.

First, disconnect the reader from the 14-pin header, and re-connect it. Wait about 20 seconds. If there was an EC:19 on the display, check the FEC display to see if the EC:19 has gone away. If it has, the communication has been re-established. The card reader may have experienced a lock-up condition, and should run fine once it has been reset by powering down and up again. Whether or not there was originally an EC:19 on the display, try several cards in the reader to ensure correct operation.
