Serial Port Connection
All communication parameters between the scanner and terminal must match for
correct data transfer through the serial port using RS-232 protocol. Scanning the
RS-232 interface bar code, programs the scanner for an RS-232 interface at
9600 baud, even parity, 7 data bits, 1 stop bit (8 bit data), and adds a suffix of a
CR LF.
1. Turn off power to the terminal/computer.
2. Connect the appropriate interface cable to
the scanner.
Note: For the scanner to work properly, you
must have the correct cable for your type
of terminal/computer.
3. Plug the serial connector into the serial port
on the back of your computer/terminal, as shown below. Tighten the two
screws to secure the connector to the port.
4. Plug the power pack into a power source.
5. Once the scanner has been fully connected, power up the terminal/
computer.
