TransCore AI142205618 Manuel D’Utilisation

Is the main power switch light-emitting diode (LED) lit? If not, turn on power 
switch.

Is the front panel fuse blown? If so, replace it with a 1.5 amp (A) slo-blo fuse.

Is the reader’s DC-DC converter functioning? If so, the OK LED on upper left 
corner of front panel will be lit.

Are you using a null modem cable connection? If not, switch to a null modem 
connection.

Have you set the correct baud rate? If an incorrect baud rate is suspected, select 
and send each baud rate in turn, using the !100x Baud Rate Select command, and 
wait for a response.

The suggestions listed here assume that the user has already verified proper serial 
communications, and the command !305 has been entered successfully to enable 
real-time transmission to the host computer. If RF POWER LED, which is recom-
mended for customer I/O connector, is lit, the indication is that the AI1422 is querying 
for tags. If the LOCK LED, which is recommended for the customer I/O connector, is 
lit, the indication is that the reader system is retrieving tag data. If either LED is not lit, 
then check the following items:

Verify that the antenna connection is good.

Verify that the antenna cable is in good condition.

Verify that a single, known valid tag is in the antenna field.

Verify that the trigger remains activated and the unit power is on.

Verify that a tag being alternated with a tag containing different data to avoid 
uniqueness filtering.

If the unit will not retain information, such as time and date stamp or baud rate 
between power cycles, the internal battery backup has failed and the unit must be 
returned for repair. Contact TransCore at the telephone number listed at the front of 
this user guide.

Except for the 1.5-A slo-blo fuse in the front panel of the unit, there are no user-ser-
viceable parts in the AI1422 Half-Frame Reader System.
