Gryphon™ BT Cordless Reading Systems

GRYPHON™ BT OPERATION

RADIO CONNECTION

The blue LED and/or the beeper always indicate the reader radio connection

status (see the table below):

• the radio connection is signaled by the blue LED through a single blink at

regular intervals, while if the reader radio is disconnected the LED emits

two short blinks at regular intervals;

• during the initialization procedure, if the radio connection attempt is

successful, the reader emits four ascending tones;

• the radio disconnection is signaled by four descending tones.

For more details and other meanings of the Gryphon™ BT indicators (LED, blue

spot and beeper), refer to the Gryphon™ BT Reference Manual on the

configuration CD-ROM.

DATA TRANSMISSION WITH A BT DEVICE

When Gryphon™ BT is connected with a BT device, the transmission of data

can be transparent (no ACK/NACK protocol), each character is read and

immediately sent to the Host (default value). Otherwise, data transmission can

be with flow control (with ACK/NACK protocol), after each reading

Gryphon™ BT waits for an acknowledge that the remote Host received the data

before reading and sending the following code.

NOTE

RTS/CTS handshaking should be set by the Bluetooth

COM

driver for correct serial communication. If not used, the RTS line

must be forced to the level that doesn't block such

communication.
