2-4 Installation and uninstallation of cable 

Note: If any of the below operation is incorrect, turn off the power immediately and check the scanner for 
any improper connections. Go through all steps again. 

2-4-1 Installation - USB 

The  scanner  attaches  directly  to  a  USB  host,  and  is  powered  by  it.  No  additional  power  supply  is 
required. 
1.

 

Refer to Figure 2-3, connect the USB interface cable to the bottom of the scanner. 

2.

 

Plug the series A connector in the USB host, or an available port of the terminal. 

3.

 

Windows will automatically detect the USB device. 

 

Figure 2-3

 

2-4-2 Installation - RS-232 

1.

 

Connect the RS-232 interface cable to the bottom of the scanner. 

2.

 

Connect the other end of the interface cable to the serial port on the host. Tighten the two screws to 
secure the connector to the port. 

3.

 

If the host does not have power supply (on PIN 9), connect the external power supply (DC adapter) 
to the RS-232 cable.
