GRYPHON™ BT SH3500

To simplify the management of this frame packing, and to avoid having to develop a

special proprietary software program, included on the CD-ROM are: the DL Security

Protocol example program, (written in Visual Basic), the Windlbt.dll, and the source

code of the example. The example program allows extraction of the data from the

frame, verification of the CRC, discarding any duplicate data (with the same counter

value), and automatic management of Frame Packing and ACK/NACK protocol in

response to each frame.

5.2.3 Power-Off Timeout

If this command is enabled, after the desired timeout in hours, the GRYPHON™ BT

SH3500 batteries are disconnected and all power consumption ceases. To restore

power, press the trigger once. The reader will now be ready to read codes.

Power-off does not effect configuration parameters.

5.2.4 Batch Mode

Batch mode allows codes to be stored in the gun on a FIFO basis whenever the gun

is out of range. In this case radio communication is not suspended and transmission

is attempted after each code read. If transmission cannot be successfully completed,

then the code is added to the list. When the gun returns in range, transmission of the

codes to the cradle resumes automatically, according to the selected communication

protocol, upon simply pressing and releasing the trigger or by successfully reading a

new code.
