TROUBLESHOOTING
The Omni reader is easy to install and use. Most problems encountered
can be attributed to:
· Incorrect Interface Cabling
· Incorrect Configuration Setup
· Bad Magnetic Stripe Quality
· Poor Bar Code Printing Quality
General Procedures
The troubleshooting process can be simplified by following these simple
diagnostic procedures.
1. The unit should emit two beeps when power is first applied and the
LED should turn green. If this does not happen, then the unit is not
receiving power or did not power up correctly.
2. Once it has been confirmed that the unit is correctly powered, try
swiping a credit card. If the decode is successful, the LED will turn amber
and the data will be sent out, accompanied by a beep. The LED will turn
amber for a short moment and then back to green after the data has been
transferred. If the decode fails, the LED will turn red for about 2 seconds
to indicate a “bad read” with no beep or one beep if just one track fails.
3. Once the unit has indicated a “good read,” proceed to check the
interface cabling connections.
