Note:
(1) DET signal is bi-directional I/O pin and for internal use only.
(2) CTS and RXD are input signals and take 0V to 5V only. If the
scanner is used to interface with a standard RS232 port, those
signals should not be connected.
Standard RS232 Interface:
To support standard RS232 interface, an RS232 adapter cable from the
manufacture must be used. This cable is a special one and cannot be
replaced by the others. One end of that cable which has RS232 signal
presented is a DB25 or DB9 female connector and has following pinout:
