RS-232 Interface 7-3
Introduction
This chapter describes how to set up the digital scanner with an RS-232 host. The RS-232 interface is used to connect the digital
scanner to point-of-sale devices, host computers, or other devices with an available RS-232 port (e.g., com port).
If the host is not listed in Table 7-2 , refer to the documentation for the host device to set communication parameters to match the host.
The digital scanner uses TTL RS-232 signal levels, which interface with most system architectures. For
system architectures requiring RS-232C signal levels, Symbol offers different cables providing TTL-to-RS-
232C conversion. Contact the Symbol Support Center for more information.
Throughout the programming bar code menus, default values are indicated with asterisks (

).
Most computer monitors allow scanning the bar codes directly on the screen. When scanning from the screen, be sure
to set the document magnification to a level where the bar code can be seen clearly, and bars and/or spaces are not
merging.
