The IT3220 and VT3060B/3080B scanners are easily
configured to work with a variety of interfaces by installing the
desired cable adapter and by programming the selected
terminal interface. After identifying the communication
interface you will use and obtaining the suitable interface
adapter cable, plug the RJ45 Phone Plug of the IT3220 or
VT3060B/3080B main cable into the connector of the selected
interface cable adapter. Please make sure the connector clicks
into place securely.

All scanners have been preset to the “IBM PC/AT, PS/2
Keyboard Wedge” interface. If you need to change the host
interface, please refer to the “Host Interface Selection”
described in Chapter 3 to find your desired interface. The
following paragraphs provide the installation of the most
popular host interfaces.
Keyboard Wedge Interface
The keyboard wedge interface allows data transmission from
the scanner to the host through the existing keyboard port as
traditional keyboard input.
PC/AT, PS/2 Keyboard Wedge
For the keyboard wedge solution, the scanner must work with
the existing keyboard concurrently. If you want to link the
scanner to a computer keyboard port without a PC/AT or PS/2
keyboard, please select “Emulate External Keyboard.”
This selection instructs the scanner to perform the power-on
handshaking and routine reply between computer and
keyboard.
