Protocol Selection

In general, the point-to-point protocols will work well in most applications. They require no address and must use RS-232 or RS-422 communication standards.

Protocols define the sequence and format in which information is transferred between the scanner and the host, or in the case of Multidrop, between the scanners and a concentrator.

Note: In all protocol modes, the Preamble and Postamble character strings can be used to frame the decoded data, and both are included in calculating the LRC (Longitudinal Redundancy Check).
