Serial Communication and Wedge Options
The following communication options are used to define how your PSC scanner communicates with the host system through its serial interface or its keyboard wedge interface.
A message transmitted from the scanner upon a successful decode has the following format:
Prefix
Terminal
ID
Preamble
Code ID
Data
Postamble
Suffix
Some of these attributes, e.g., prefix, preamble, etc., may not be required or may vary from one host system to another. The parameter selection process allows you to tailor these elements for the particular requirements of your host system. You may also program an inter- character delay to prevent data overrun problems with your host ter- minal.
Options specific to serial communications are:
Baud Rate | Protocol |
Parity | Inverted Serial |
Stop Bits | External Trigger |
Word Length | Buffering Level |
Each of these options is discussed in greater detail in the section on Serial Communication Parameters.
