6. Electrical Specifications
6.1. Configuration
The OPR 3201 consists of a laser module (which includes a scan mirror, a coil, and a
photo diode), a decode and communication section (which decodes scanned data and
carries out signal processing), a 3.3 V power supply, an interface (which outputs decoded
data), a buzzer, LEDs, and a trigger key.
The OPR 3201 RS-232C model operates on a DC 6.0 V power supply fed from the
dedicated adapter. USB and Wedge models operate on bus power, so those models do
not use an adapter.

a) No Handshaking
The scanner attempts the communication regardless of the state of the host
computer.
Figure 12: No handshaking
b) BUSY/READY
The scanner and the host computer notify each other of their state and
whether they can receive data with BUSY/READY through an RTS line. They
can communicate state to each other through a CTS line when connected as
in the following figure.
Figure 13: Busy/Ready communication
The scanner stays ON (is able to receive data) except during certain parts of
the process, such as receiving data (buzzer command execution), transmitting
data, and menu processing. The scanner checks the CTS line before
transmitting data. When it is ON, the scanner transmits data. When it is OFF,
the scanner waits for it to turn ON within a set time. The scanner will abort
transmission with an error indication (buzzer) when the CTS line is not ON
