Installed as an USB Interface

Installation procedures:

You can install the scanner with the USB interface cable to work with either PC or iMac USB port.

RS232 Serial Interface

To use the scanner as a RS232 serial interface, a RS232 interface cable and a power adapter are

required.

Installation procedures:

1. Make sure the scanner’s cable has the right connector and pinout for the RS232 port of the host

device. If the pinout is different from device, swapping pins is necessary to achieve proper

communication.

2. If the host device has power output at RS232 interface port, the scanner can be powered by

connecting that power line to pin 9 of the scanner connector. If there is no power at RS232 port,

An AC adapter is needed. Plug the adapter into the DB type connector at the end of the interface

cable.

3. Plug the DB type connector of the interface cable into host’s RS232 port and power up the

device.

4. When the scanner is powered, a long beep sound indicates the scanner is ready to use.
