scanning the Hex 1 tag. The default is to disable
Periodical Codes.
If you choose to disable Periodical Codes, there are no
other entries allowed for this parameter. Scanning the
Hex
0 tag also causes the scanner to go back to the Base
Programming state. However, if you enable Periodical
Codes, you must program the following parameters.
Periodical Code Extension(7890 0200 model)
The Periodical Code Extension parameter option has
three selections: 2-digit extension only, 5-digit extension
only or either 2- or 5-digit extensions. Scan the Hex 0
tag for 2-digit extension only, the Hex 1 tag for 5-digit
extension only, or the Hex 2 tag for both 2- and 5-digit
extension. The default is 2- and 5-digit extensions.
Scanning a valid Hex tag causes the program to go the
next parameter option.
Send Data (7890 0200 model)
The Send Data parameter option has three selections:
Data As Decoded, Periodical Code Data Only, and 7F
Hex If Periodical Data Not Decoded. If you scan a Hex
0
tag, the data is sent as decoded, whether or not there
are extension digits. If you scan a Hex 1 tag, only valid
periodical codes are sent. If you scan a Hex 2 tag, a
hexadecimal 7F is sent as the extension if the scanner
could not read a 2- or 5-digit code. The extension is sent
after the main tag data. The default is Data As Decoded.
Scanning a valid Hex tag causes the program to go the
Base Programming state.
