USING GRYPHON™ BT SERIES READERS

Gryphon™ BT series readers, together with a Bluetooth
device, build a Cordless Reading System for the collection, decoding and
transmission of barcoded data.

The Gryphon™ BT (Gryphon™ Bluetooth®) reader is a CCD wireless barcode
scanner communicating in the 2.4 GHz ISM band and using the Serial Port
Profile (SPP). The Bluetooth
printer, etc with a built-in Bluetooth
(i.e. a Bluetooth

®

dongle).

®

compatible remote device can be a PC, PDA,

®

device or with external Bluetooth® adapter

Using this Quick Reference Manual, you can initialise and start using
Gryphon™ BT reader with its default values. For details about general
configuration commands, refer to the Gryphon™ BT Refence Manual on
the configuration CD-ROM.

Gryphon™ BT readers automatically scan barcodes at a distance. Simply aim
the reader and pull the trigger. Code scanning is performed along the center of
the light bar emitted from the reading window. This bar must cover the entire
code.

READING ANGLE

Successful scanning is performed by tilting the reader with respect to the
barcode to avoid direct reflections which impair the reading performance, see
the figure below.

Successful reading is signalled by an audible tone plus a good-read blue spot.

OK Not Advised

To start using your Gryphon™ BT reading system you must:

1. Have a compatible remote Bluetooth® device (with built-in Bluetooth® radio
or an external Bluetooth

®

adapter) ready to work. See your Bluetooth®

compatible device documentation.

2. Charge the Gryphon™ BT battery using C-GRYPHON charger as
described in this Quick Reference manual. A full charge takes 4 hours
with NiMh batteries.

3. Configure the reader as described in this Quick Reference manual under
"Gryphon™ BT Configuration".

CHARGING THE BATTERIES

By placing the reader onto the C-GRYPHON battery charger it is possible to
charge the Gryphon™ BT batteries. Make sure the charging LED goes on.

The LEDs positioned on the cradle signal the charge status, as described in the
following table:

LED STATUS

Yellow

Red On = the battery charge is in progress.
Green On = the battery is completely charged.

On = C-GRYPHON is powered.

After many

recharging cycles NiMh and NiCd batteries may tend to lose their
operating autonomy. This condition can be overcome by positioning the
Gryphon™ BT onto the C- GRYPHON charger and pressing the “battery
reconditioning” button. A discharge cycle may last up to 2 hours.

Changing the Batteries

When the above procedure is no longer effective, the batteries must be
changed. To change the batteries of your reader, unscrew the battery cover
screw, replace the old batteries with new ones, then insert the cover in the
handle and screw it back into place. (See the following figures).

+

Dispose of the batteries as required by the relevant laws in force.

CAUTION

Powering the C-GRYPHON

Connections should always be made with power off!

CAUTION

Apply power to C-GRYPHON by connecting a power supply unit to the connector
on the base of the battery charger.

C-GRYPHON is ready to charge Gryphon™ BT Series readers with NiMh or NiCd
batteries.

GRYPHON™ BT OPERATION

RADIO CONNECTION

Gryphon™ BT as Slave

A Gryphon™ BT is Slave when it sends barcodes to a Master remote
Bluetooth
communication.

Once set as Slave, a Gryphon™ BT reader requires no particular configuration
for communication, however some radio parameters can be set to increase
system performance and data transmission security, see the Gryphon™ BT
Reference Manual on the configuration CD-ROM. At startup the reader can only
wait for the Master to initialize the radio communication.

The following is a general procedure recommended for Gryphon™ BT Slave
applications:

1. Power up the remote Bluetooth

2. Power up the Gryphon™ BT reader within radio range (10 meters).

3. From the remote Bluetooth

4. Check that "Gryphon BTx00 " is shown among the discovered

5. Request to open an SPP connection with Gryphon™ BT, making

After the Gryphon™ BT reader indicates radio connection (see the Status LED

Indicator table), you can start sending barcodes.

Gryphon™ BT as Master

A Gryphon™ BT is Master when the remote Bluetooth® device is Slave, i.e.
with a Bluetooth

wants to communicate.

By default, at startup the reader initializes the communication with the Slave. If
the connection is successful, the reader can send barcodes to the Slave
device.

If the connection is not successful, you can attempt a connection manually by
double-clicking the reader trigger
manually as described in the Gryphon™ BT Reference Manual on the
configuration CD-ROM.

SLEEP STATE

The µP in the reader enters a “Sleep” state after 5 minutes of no reading for
minimum power consumption.

DATA TRANSMISSION

The transmission of data can be transparent (no ACK/NACK protocol), when
each character is read and immediately sent to the Host (default value).
Otherwise, data transmission can be with flow control (with ACK/NACK
protocol), when, after each reading, Gryphon™ BT waits for an acknowledge
that the remote Host received the data before reading and sending the
following code.

RTS/CTS handshaking should be set by the Bluetooth
