Description
This meta tag causes the business application to exit and the UCA
client application goes back to the UCA client application desktop.
This means the user is still logged in and has access to the
menus, walkie-talkie or phone calls.
Parameters:
enabled- Enables the scanner.
disabled- Disables the scanner.
autoenter- Automatically appends a carriage return to the end of
any bar codes scanned.
autotab- automatically appends a tab to the end of any bar
codes scanned.
This meta tag allows the business application developer to enable
or disable the scanner as well as append a carriage return or tab
to the end of the scanned label.
Note: The enable and disable parameters are only necessary
when the business application developer wishes to use the
custom "scannernavigate" meta tag.
This custom tag allows scanner data to be passed back up to the
UCA server.
Return Values:
Data- The data decoded by the scanner or imaging device.
Source- The source device and human readable decoder type of
the decoded bar code or symbol.
Type- Hex value representing the decoder type.
Time- The time at which the decode occurred (hh:mm:ss).
Length- The length of the decoded bar code or symbol.
Retrieval tags return information by replacing the text '%s' within
the content parameter of the meta tag. Each '%s' represents 1
return value, if there are less than the maximum return values
allowed for with '%s' place holders, the return values are supplied
in sequence for that for the amount supplied. For example:
<meta http-equiv="scannernavigate"
content="PriceLookup.htm?label=%s;source=%s;typ
e=%s;time=%s;length=%s" />
This custom tag causes the device to suspend (sleep) once the
business application page is received and parsed.
This custom tag enables/disables symbologies which are not
enabled by default. This tag can also set/modify the properties of
the symbologies.
Parameters:
Symbology Name: Any of the symbologies supported by CA 50.
Refer to page [scanner symbologies section]
Ex: Code128, Codabar, Code11, etc.
Properties: properties specific to symbologies
Ex: Enable, Disable, minlength, maxlength, etc.
