Publication 2755-6.8
The following illustration shows the wiring base connections
between the AdaptaScan Bar Code Reader and the personal
computer. This RS-232 serial connection is used to download match
codes to the reader from a terminal emulator. Do not connect the
cable to the computer until after the application is downloaded to the
reader (see page 3–10).
Create a cable using Belden 8303 (or equivalent) and a connector (to
match your computer’s RS-232 port). The other end of the cable is
wired to the RS-232 port in the reader wiring base.
