Motorola LS9203 用户手册

6-3

This chapter covers RS-232 host information for setting up the scanner. The RS-232 interface is used to attach the scanner to point-
of-sale devices, host computers, or other devices with an available RS-232 port (e.g., com port). 

This scanner utilizes TTL RS-232 signal levels, which will interface with most system architectures. For 
system architectures requiring RS-232C signal levels, Motorola offers different cables providing the TTL to 
RS-232C conversion. Please contact the Global Customer Interaction Center for more information.

If the particular host is not listed in 

, set the communication parameters to match the host device. To set 

communication parameters for hosts not listed, refer to the documentation for the host device.

Throughout the programming bar code menus, default values are indicated with asterisks (

).

This connection is made directly from the scanner to the host computer.
