BCL 8

After each reading via an ’RTy’ command, explicitly switch off the function again since failure to do so
will interfere with other commands as well as prevent execution of a new ’RTy’ command.
Reading a reference code
Alignment mode
Command
’RR’
Description
The command reads out the reference code defined in the BCL 8. If no
parameters are specified, all defined codes are output.
Parameter
<Reference code number>
’1’ Reference code 1
’2’ Reference code 2
Acknowledgment
If no reference codes are defined, the BCL 8 responds with the ’RS’ com
-
mand and corresponding status (see Command ’RS’).
For valid codes, the output corresponds to the following format:
RCyvxxzzzzzz
y, v, x and z are placeholders (variables) for the actual input.
y
Def. reference code no.
’1’ (Code 1)
’2’ (Code 2)
v
Storage location for reference code
’0’ RAM+EEPROM
’3’ RAM only
xx Def. code type (see Command ’CA’)
z
Def. code information (1 … 30 characters)
Command
’JP’
Description
This command is used for simplified mounting and alignment of the BCL 8 in
static installation situations. After activating the function with ’JP+’, the scan
-
ner continuously supplies status information to the serial interfaces.
With this online command, the scanner is set to terminate the decoding after
100 successfully decoded labels and output the status information. Subse
-
quently, the read process is reactivated automatically.
As status, the output returns the following values:
• scans which contain the valid label information on the basis of
100 scans,
• the decoding result.
These values can be used to determine the decoding quality.
In addition to the output of the status information, the laser beam is used to
display the reading quality. Depending on how many labels were able be
extracted, the duration of the laser's "off" time increases.
If the reading quality is high, the laser beam flashes in brief, regular intervals.
The worse the decoder decodes, the longer the pauses become during which
the laser is switched off.
Parameter
’+’: Starts the alignment mode.
’-’: Ends the alignment mode.

xxxxx: "Scans since reading gate release" (scans_with info):
Number of scans that contain valid label information. The maximum
value is 100.
yyyyy: Bar code information.
