3.2.1 RS232 Interface
The main serial interface is used in this case for point-to-point connections; it handles
communication with the host computer and allows both transmission of code data and the
programming of the scanner. This is the default setting.
The following pins are used for RS232 interface connection:
CBX100/500
Function
TX Transmit Data
RX Receive Data
RTS Request To Send
CTS Clear To Send
SGND Signal Ground
It is always advisable to use shielded cables. If the shield is tied to ground at the Host, then
leave it floating at the CBX. If it is floating at the Host then tie it to Shield at the CBX. The
overall maximum cable length must be less than 15 m (50 ft).

Figure 25 - RS232 Control Signals
The RTS and CTS signals control data transmission and synchronize the connected devices.
If the RTS/CTS handshaking protocol is enabled, the DS6300 activates the RTS output to
indicate a message is to be transmitted. The receiving unit activates the CTS input to enable
the transmission.
