Reader Lights and Buzzer Alarm
Both the magnetic slot reader and the magnetic hand scanner have three
lights and a buzzer alarm; the three lights
are
colored green, yellow, and red.
One
of
the three lights
is
on whenever your display station
is
powered on and
the reader or scanner cable
is
connected
to
your
display station.
The green light turns on when
(1) the display station
is
turned on or (2) a coded
message
is
successfully sent to the control unit. This light turns
off
during a
card reader operation when you pass the card through the reader slot or pass
the scanner over the card stripe.
If
the coded message on the card
is
successfully
sent to the control unit, the green light turns
on
again.
If
the operation
is
unsuccessful, the red light turns on.
The yellow light turns on when the card
is
successfully read
by
the magnetic
slot reader or the magnetic hand scanner and remains on until
(1) the coded
message on the magnetic stripe is successfully sent
to
the control unit or (2)
an error
in
the transfer
of
the coded message
to
the control unit
is
detected.
Subsequent read operations are ignored while the yellow indicator
is
on.
If
the
operation
is
successful, the yellow light turns
off
and the green light turns on;
if
the operation
is
unsuccessful, the yellow light turns
off
when the red light
turns on.
The red light turns on
if
an
error occurs (1) while the card
is
read or (2) during
the transfer
of
the coded message
to
the control unit.
The alarm buzzer on the reader or
on
the scanner produces a short tone
(for
about one quarter
of
a second) when the green light turns on and a long tone
(about one second) when the red light turns on.
Magnetic Slot Reader or Magnetic Hand Scanner Operation
To operate the magnetic slot reader or the magnetic hand scanner:
1.
Turn on the display station, or,
if
you
are using the display station, complete
the job
you
are presently working on.
2.
Ask the appropriate person in your organization, or check the user's program
guide, to determine where you should position the cursor in the input field
to be used for the reader operation. Remember that,
if
the cursor
is
placed
in a protected field, the coded message on the magnetic striped card
will
not be read into the host system.
3. For the magnetic slot reader, insert the magnetic striped card into the reader
as
shown in Figure 4-4 and pass the card through the slot in the reader.
4. For the magnetic hand scanner, pass the scanner over the magnetic stripe
as
shown in Figure 4-5. In some cases, the scanner can be passed over
the card in either direction.
Check with the proper person in your
organization
to
see
whether the magnetic stripe can be read in
both
directions.
If
the card
is
read successfully, the green light on the reader turns back on,
and the cursor moves to the character position
that
follows the position
occupied by the last character read. The characters on the card
mayor
may
not be displayed on the screen.
