1 INTRODUCTION
The DL Cordless Card™ is a PCMCIA card developed to provide wireless 433 MHz
RF communication between a laptop or a vehicle mounted terminal (Host) and
Datalogic RF devices or base stations, which are STAR-System™ compatible:
-
Gryphon™ M Readers
-
Dragon™ M Laser Scanners
-
STAR Modem™ Radio Modems
-
Formula Basic Line RF Terminals (F734-E/RF, F725-E/RF, F660-E/RF)
-
STARGATE™ Base Stations
1.1 OVERVIEW
DLCC provides a wireless bi-directional communication between the Host and the RF
devices. DLCC installed in a vehicle mounted terminal is a Server (receiver) to the
RF Devices and also a Client (transmitter) to STAR Modem, which receives data for
the printer (Figure 3).
STAR-System™ uses the Narrow Band RF radio and Datalogic CSMA/CA protocol
to automatically link and manage all the RF devices in the system. This protocol
manages the data transmission using a 16-bit CRC checksum.
All RF devices in the
system must implement the CSMA/CA protocol and therefore be configured using
the STAR-System™ setup procedure.

To configure the card for operating in this mode refer to paragraph 2.2.
