6. If you are able to communicate with the
Reader from the local PC, check the
integrity of the communication line
between the Reader and the PC.
7. After fixing the communication line’s
integrity, reconfigure the 95 Series RFID
System and check whether the Reader can
communicate with the PC.
8. If you cannot communicate with the
Reader (Step 5), check Probable Cause 3.
1. Open the Reader’s enclosure and connect
the PC directly to the Reader using the
RS-232 communication line. See
Connecting the RS232 Communication
Line on page 2-2.
2. Switch off the Reader’s power supply for
at least 5 seconds, then perform the steps
in the
Reader’s Power-up Sequence on
page 5-3.
3. If the power-on test is successful, the
DATA LED should start flashing
continuously at the rate of 1.4 Hz.

typing:
ISC, and pressing <Enter>. If the
Reader responds with ISC = 0, setup
the Reader’s System code again by
typing:
ISC = your SC, and pressing
<Enter>.
5. If the Reader restored one of its
parameters to the default value, all other
parameters are also reset to their default
values. Check and reset all the
application- specific parameters to their
original values.

values. If these parameters have default
values 73 and 105 respectively, you must
set them again using the correct values
from Lyngsoe’s database.
