Troubleshooting
If the
device
is not
working
or the
following error message
displays:
1. Check
to
be sure
the
device
is
plugged
into the
USB
or
RS-232 port.
When the
workstation
is
on and no card
is
being read,
the
LED
is
red.
A
valid
proximity
card causes
the
LED
to turn
green, provided
the
configuration
is not
set
to
only read certain
bit lengths.
2.
Only one
COM port
application can
own the
RS-232
port at
a time. Make sure there
is not
another
COM port
application running. This prevents
our
software
from
seeing
the device.
3. Verify the
correct model and
the
software configuration
screen agrees
with the device
attached.
4. Verify the port
agrees
with the
workstation
c
onnect
or
.
5. If the
device
still
does
not
work, unplug
it,
remove ‘General USB Device’ using
Windows
‘Control
Panel’
a
‘Add/Remove’
Hardware. Then reboot
the
workstation.
When the
workstation boots up, re-attach
the
device USB and
the
OS should re-install
the Windows
driver
automatically
.
Change
the
release
time to 1000
on
the
Timing
tab for
USB keystrokes
to
slow down
the
de
vic
e.
Open Notepad
or Word
and swipe a card
to
display
the
card data
to
see
the
actions
of any
non-printable
symbols.
If the
device does
not
read
the
card, contact
the
card
manuf
actur
er
/
vendor
to
verify
that the card
type
is
compatible
with the
device
model.
