Main Interface - Datalogic DS6300 Reference Manual

INSTALLATION

Main Interface

The main serial interface is compatible with the following electrical standards:
RS232
RS485 full-duplex
RS485 half-duplex
The main serial interface type and its relative parameters (baud rate, data bits, etc.) are
selected via software using the Genius™ utility program. For more details refer to the
section "Main Serial Port" in the Genius™ Help On Line.
Details regarding the connections and use of the main interface selection are given in the
next paragraphs.
RS232 Interface
The main serial interface is used for communication with the Host computer and allows both
transmission of code data and configuring the reader.
The following pins of the 25-pin and 26-pin connector are used for RS232 interface
connection depending on the reader model:
The RTS and CTS signals control data transmission and synchronize the connected devices.
If the RTS/CTS hardware protocol is enabled, the DS6300 activates the RTS output to
indicate a message can be transmitted. The receiving unit must activate the CTS input to
enable the transmission.
