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 configuring the scanner.
The following pins of the 19-pin connector are used for RS232 interface
connection:

R
TX232

S

N

signal ground
The RTS and CTS signals control data transmission and synchronize the
connected devices.
If the RTS/CTS hardware protocol is enabled, the DS6100 activates the RTS
output to indicate a message can be transmitted. The receiving unit must
activate the CTS input to enable the transmission.
