10. ERROR HANDLING
10.1 Magnetic Card Read Errors
If a card read is bad no data will be returned when track data is requested with the T1,T2,T3,
or TA commands.
The :SR<CR><LF> command will return the status of the most recent card swipe
The status return string contains data on Missing STX, ETX, and LRC errors for each track
Please see the details of the :SR command in the preceding section
10.2 Communication Errors
The UCIMAG will acknowledge most RS232 commands with either a data string or <CR><LF>.
Please see preceding section for details. If the UCIMAG fails to receive the command correctly
it will not respond. The Host PC control software should assume that if no response is received
in 1 second a communication error has occurred and the command should be resent.
10.3 Power Failure
If power fails and is then restored, the unit is reset and reinitialized. On reset the UCIMAG will send
the current firmware revision. In this way a host PC can tell when power has been lost on the UCIMAG.
