Chapter 3 RS232 Serial Interface

3.1Installation

To use the scanner as a RS232 serial interface, a RS232 interface cable and a power adapter are required. See Chapter 8 for cable pinout and adapter specification. Figure 2 shows an installation diagram for your reference.

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.
