Troubleshooting
Loopback Mode
It is possible to reset the AI1422E Reader to default by looping back the TX from the RS232
into the RX via a short wire. Installing a loopback will cause the reader to reset its settings
to factory default, which is extremely useful during troubleshooting. The procedure for
resetting the reader is below.
13. Power down the AI1422E reader by switching the main power switch to the ‘OFF’
position.
14. Slide the Interface Selection switch on the front panel of the reader to RS232.
15. Install a loopback connector to the MAIN RS232 port.
16. Apply power to the AI1422E reader by switching the main power switch to the ‘ON’
position.
17. Wait 30 seconds for the reader to complete the factory reset.
18. Power down the AI1422E reader by switching the main power switch to the ‘OFF’
position.
The reader should now be configured for factory default settings.
